Abstract and Figures

A clear majority of smallholder farmers in commodity value chains such as cocoa, tea, coffee and oil palm are struggling to earn a living income. This despite numerous interventions in the past two decades, aiming to lift them out of poverty. Interventions have ranged from training, to voluntary sustainability certification and the provision of free or subsidised inputs, to the support of farmer groups. They also included community-level provision of infrastructure, such as school buildings, medical centres and access to potable water. Unfortunately, these measures and policies have not lifted smallholder commodity farmers above the $1.90 World Bank poverty line or a living income, nor have they halted deforestation. For more than 50% of the cocoa and tea farmers included in the research, household income would need to double for them to earn a living income. In this white paper on sustainable commodity production, Wageningen University & Research researchers propose various approaches, aiming to create significant impacts on the income earned by commodity farmers and their household members and to protect both forests and biodiversity.

Wageningen Economic Research | White paper on sustainable commodity production 2
Interventions and policies in the cocoa, tea and coffee sectors have failed to ensure
that all smallholder commodity farmers earn more than the $1.90 World Bank
poverty line or a living income, and they have not halted deforestation. Commodity
farming is strongly associated with deforestation, in spite of interventions. For
more than 50% of the cocoa and tea farmers in our datasets, household income
would need to double in order for them to earn a living income. For those farmers,
farming will never be a primary pathway out of poverty.
In this paper, we explore data and the literature to
propose approaches towards creating signicant impacts
on the income earned by commodity farmers and their
household members, and towards protecting both forests
and biodiversity. Our key messages are as follows:
A minority of smallholder commodity farmers earn
or could earn a living income from primary com-
modity production. For many farmers primary agricul-
tural production of global commodities will never be a
pathway out of poverty because of small farm sizes and
low productivity levels.
Price increases at scale can play an important role,
but require supply management to offer stable long-
term income impact without negative impact on forests
and biodiversity.
A tailored approach is needed. Smallholder commod-
ity farmers who cannot earn more than the living
income need alternatives, such as employment
opportunities, so that they can move out of agriculture
when land reform is implemented.
Farmers remaining in agriculture should have the
opportunity to increase farm sizes through appropriately
implemented land reform.
Such farmers should obtain support in land use
change if they are situated in areas affected strongly by
climate change. Such support should take into account
the entire farm, not the commodity eld only.
In identifying the farmers who will or will not be lifted
out of poverty by agriculture-based interventions, swift
and effective decisions can be made on where and
how to invest time and funds. In this way, policies
and programmes can be implemented more cost-effec-
tively, farmer’s frustrations can be avoided, as well as
any time and costs associated with non-adoption.
Policies and interventions must take into account
contextual and personal factors which can inuence
farmers’ behaviour. People in rural areas should be
listened to about their aspirations, needs and opportuni-
ties.
Forest and biodiversity protection works best with
multiple simultaneous interventions tackling all drivers
of deforestation, including a strong role of the local
population, sharing of information (data) and ultimately
a concerted action between public and private stake-
holders from different sectors, in order to prevent any
shifting of the problem to some other sector or place.
For designing effective and efcient interventions,
ndings should be shared between countries and across
commodities on what works and also what failed to
work. This includes the sharing of data and methodolo-
gies in order to avoid too much data being collected too
many times, with too many farmers being interviewed
too often, to satisfy the needs of various buyers and
implementers.

Interventions in cocoa, tea, coffee and oil palm
sectors generally have resulted neither in lifting
smallholder farmers out of poverty nor in forest and
biodiversity protection.
Smallholder farmers in commodityi value chains such as
cocoa, tea, coffee and oil palm have received numerous
interventions from private sectors for food and agribusi-
ness traders, processors and manufacturers, as well as
public sector agencies in the past two decades aiming to
improve their incomes and lift them out of poverty.
Interventions have ranged from training, to voluntary
sustainability certication and the provision of free or
subsidised inputs, to the support of farmer groups, to
community-level provision of infrastructure, such as
school buildings, medical centres and access to potable
water. However, most interventions have had limited,
mixed or no impact on household incomesii. Despite those
interventions, in the majority of commodity farm house-
holds, incomes per capita are below living income stand-
ards1. In Figure 1, we show examples from our research
that support this nding for important cocoa and tea
producing countries2.

For more than 50% of the cocoa and tea farmers in
our datasets, household income would need to
double in order for them to earn a living income.

the living income line (Figure 2)iii, a benchmark income
level which is more and more often set as a goal by both
the public and private sectorsiv. These challenges lead to
the question of whether and how such farmers can be
supported to earn a living income. This is the rst ques-
tion that will be addressed in this paper.

Commodity farming is strongly associated with
deforestation and biodiversity loss, despite
interventions.
A large body of research shows that commodity farms
have often been created in forested areas or previously
forested areasv. These agro-ecological areas are suitable
for growing commodity tree crops, as their wild ancestors
originated from forests. Population increases and the
fertility of forest soils have led farmers to convert forested
areas to farms in order to sustain their families and to
satisfy the increasing demand for commodities. This
expansion, combined with a general lack of investment in
already cultivated elds, is strongly associated with land
degradation, biodiversity loss and deforestationvi.
Reforestation or compensation measures have had limited
success in halting or mitigating these impactsvii.
Based on the literature and the data from our cocoa
and tea research, we propose approaches for signi-
cantly impacting household incomes, as well as the
protection of forests and biodiversity.
In this paper, we present information on smallholder cocoa
farmers in Ghana and Côte d’Ivoire, as well as smallholder
tea farmers in Kenya, in order to assess whether and how
such farmers can be better supported (Section 2).
Through a literature review that focuses on overview
studies and systematic reviews, we investigate why past
interventions have not had the expected effects, an
investigation that reveals contextual and personal factors
which inuence farmer behaviour (Section 3); we also
draw conclusions about how best to address drivers for
deforestation (Section 4). Finally, we present and reect
on strategies for impacting smallholder commodity farmer
incomes (Section 5), and we conclude with recommenda-
tions for the public and private sector (governments and
businesses) and NGOs on both increasing farmer incomes
and protecting forests and biodiversity (Section 6). Finally,
we present a research agenda for transformational science
to facilitate smallholder farmer sustainable development
(Section 7).

2 There is no business case for lifting the poorest farmers
out of poverty
4 See for more information on how the living income is calculated in Appendix 1.
5 In these calculations, it is assumed that the $400/tonne living income differential would end up totally in the farm gate price.
Even when farmers’ incomes increase,
many remain poor.
Interventions aimed at income enhancement and lifting
farmers out of poverty are often based on the assumption
that the latter should be attainable through said interven-
tions. However, for many farmers this is an unachievable
goal due to the conditions in which they live. Even if
farmers’ incomes from cash crops were to directly
increase – for example, through increased farm gate
prices – we observe that small farm sizes and low produc-
tivity levels lead to only a few farmers moving to another
income group. Figure 3 shows that even if farm gate
prices for tea were to increase by 50%, only 6% of
farmers would shift into the group of farmers earning
more than the living income line (see Figure 1 for baseline
gures)4. Such price increases, moreover, are not expect-
ed, and if increases were not properly managed, they
could lead to unwanted market effects, such as large
increases in volumes produced, putting pressure back on
price levels.

Source: Ghana: Waarts et al., 2014 (N = 311), Côte d’Ivoire: Ingram et al., 2018 (N = 362), Kenya: Waarts et al., 2015 (N = 439).
A recent political deal between the governments of Côte
d’Ivoire and Ghana requires chocolate companies to pay a
living income differential of $0.40 per kilogram ($400/
tonne) on all 2020/2021 season cocoa contractsviii, on top
of the market price. The ICCO daily price was $2408/
tonne on 7 November 2019ix. At such a price, the price
increase would constitute 17%. Any increase in smallhold-
er farmers’ incomes is a step in the right direction since
they are often poor, but even under the assumption that
the full premium ends up with the farmers, it would not
help most out of poverty. An increase per kilogram will
yield the largest benets for farmers in higher income
groups, as they produce larger volumes. Based upon our
data, a $0.40 increase per kilogram would yield approxi-
mately a $205 increase in yearly income for farmers
earning less than the poverty line in Ghana and a $360
increase in Côte d’Ivoire. In addition, such an increase
would positively affect the yearly income of farmers
earning more than the living income standard in Ghana by
$832, and in Côte d’Ivoire by $17075. For our analyses on
the usefulness of this living income differential, see
Section 5.
The fact that smallholder farmer household incomes
have often not increased is the result of relatively
intractable farmer characteristics, such as farm size,
in combination with low productivity levels.
Cocoa and tea farm sizes are generally small, and with the
exception of Ghana, they are much smaller among
smallholder farmers earning less than the living income
than they are among farmers earning more than the living
income (Figure 4). We nd that the farm sizes for farmers
We observe that only few farmers move to
another income group
Wageningen Economic Research | White paper on sustainable commodity production 6
in the tea sector in Kenya are particularly small, while
inheritance and a growing population drive down the
mean farm size even furtherx. Farm sizes for cocoa are
larger, but the returns of these larger plots in terms of
income earned are often similar to the returns of tea
farmers farming smaller plots of land. Even if there is a
possibility to increase a commodity’s productivity or to
produce a more protable crop on (part of) the land,
these can only lead to marginal increases in income, as
total volumes produced will remain small. Thus, the
income earning potential of small plots is limited. We nd
that the low incomes of the poorest farmers are explained
by low productivity levels in combination with small farm
sizes.

Low average productivity levels prevail, not having
signicantly improved in decades, despite
interventions.
Productivity levels for smallholder farmers are generally
far below maximum achievable levels (Figure 5). Only
very few farmers achieve high levels of productivity. On
the one hand, this indicates the potential to increase
farmer productivity. On the other hand, the literature and
data show that average productivity per hectare has not
signifcantly improved in decades, despite interventionsxi.
Our evaluations show that it is difcult to signicantly
increase farmer productivity since various factors inu-
ence farmers’ investments. Interventions in cocoa in
Ghana and Côte d’Ivoire outcomes were mixed and
generally modestxii. In Kenya, we found that tea farmer
participation in farmer eld schools did affect productivity,
but adoption levels remain low and generally productivity
levels remain far below the maximum achievable levelxiii.
In all three countries, farmers in the lowest income group
have the lowest levels of productivity.

maximum productivity was established in these studies based on feedback from agronomists in the areas we studied.
Farmers have more land than just for cocoa and tea.
Farmers do have other land available besides tea or cocoa,
indicating that one must consider the entire farming
system instead of the cocoa and tea elds only if one is to
accurately assess how to best support the farmers.
However, such additional land parcels are not often
sufcient for generating substantial income (Figure 6).
Small farm sizes, combined with challenges in acquiring
and enlarging farm size, as well as encroachment upon
forested land, are barriers for farmers to earn more.
Farmers are quite dependent on commodity in-
comes, leaving little room for income diversication.
Income diversication can be an important way to im-
prove farmer resilience. In our cocoa studies, a large
proportion of farmer income is earned y producing the
commodity (about 80% in Ghana, 90% in Côte d’Ivoire
and 70% in Kenya, Figure 6). In particular in our study,
cocoa farmers in Côte d’Ivoire have very few alternatives
other than cocoa production to generate income, leaving
them vulnerable to climatic and price uctuations.
Wageningen Economic Research | White paper on sustainable commodity production 8
Another study indicates that cocoa farmers in Côte
d’Ivoire are dependent on cocoa for 66% of their income
and farmers in Ghana 61%.xiv . Many farmers are thus
very dependent on cocoa production for earning their
income. The lack of options for diversication may have
different causes: the household may not have excess
labour or land available to invest in on- farm or off-farm
income generation, or other income opportunities may
simply not be available.

There is no business case for lifting the poorest
farmers out of poverty.
Productivity levels, combined with small farm sizes of
smallholder farmers earning less than the World Bank
poverty line, suggest that there is no business case of
increasing income levels such that all farmers earn more
than the living income lines. Not only are farmers in the
lowest income group the most vulnerable to shocks, they
also have very limited opportunities to increase productiv-
ity and diversify. Moreover, even if opportunities were
more available, such famers still likely would not be lifted
out of poverty, especially in Côte d’Ivoire and Kenya,
where the lowest-income farmers have signicantly
smaller farms than those in other income groups.
Improving farmers’ productivity has not been and will
not be enough to lift them out of poverty.

3 Contextual and personal factors to be addressed in policies
and interventions to be able to inuence farmers’ behaviour,
increase farmer incomes and protect forests and biodiversity
Contextual and personal factors impede farmers from
changing farm management practices that could increase
household incomes and protect forests and biodiversity.
Our research, conrmed by the literature shows that, even
if farmers adopt new farm management practices, many
farmers do not adopt the recommended practicesxv.
Furthermore, if farmers do adopt new practices, they
rarely adopt all recommended practicesxvi.
Required investments present nancial risks for
farmers, while farmers often lack the means to
invest.
Studies have shown that farmers are often resistant to
change, or dis-adopt after initially adopting new technolo-
giesxvii. This is due to different reasons which can be
roughly divided into four categories, see next page.

1 Inability to afford investment
Smallholder farmers may resist technological innovations,
given that required investments often present nancial
risks and even losses in the short term, while smallholder
farmers often lack a credit basis for nancial invest-
mentxviii. Farmers often cannot afford recommended inputs
(including hired labour) or spend their often scarcely
available cash on other living expenses, such as school
fees or food. In addition to nancial investments, im-
proved farming practices usually require substantive
additional household labour requirements which make
them unattractivexix.
2 Investment benets not guaranteed
Future benets are not guaranteed. Farmers may decide
not to adopt new practices because those practices might
not lead to signicant income increase, for instance when
farming small parcels of land, or when inferior planting
material will not respond to improved practicesxx. Adoption
of technology only leads to increased agricultural produc-
tivity under specic circumstances and conditions which
cannot be broadly recreatedxxi. Farmers base their motiva-
tion and effort level on their expectations of the new
practice or technology, and if they experience that the
extra effort does not meet their expectations, they will
decrease their effort levels in the next season.xxii
3 Failing markets prompt constraints
Failing markets often lead to adoption constraints. Inputs
such as fertiliser, crop protection products and hired
labour are often not available – or they are available but
not at the right time. In addition, quality of inputs cannot
be assessed by farmers. The asymmetry of information
6 ‘Transhumance is the regular movement of herds between xed points to exploit seasonal availability of Pastures’ (FAO, 2001)
about quality of inputs increases the risks for farmers to
invest in seeds or fertiliser of insufcient qualityxxiii.
4 Interventions are often not tailored to aspirations,
needs and opportunities
Finally, interventions often are not tailored to farmers’
aspirations, needs and opportunities—moreover, they are
implemented from a technocratic perspective. They hardly
consider personal factors that determine the motivation to
adopt new farming practices. For example, new practices
may conict with social norms. In Burkina Faso, for
instance, crop livestock integration is a technology that
has clear benets and improves status for crop farmers
because livestock is a sign of wealth. However, crop
livestock integration is seen as a failure by transhumant6
livestock herders, as it forces them to work the land,
which is considered a last resort for those who cannot live
anymore off of their herds (Slingerland, 2000). Social
networks and norms can have a strong impact on technol-
ogy adoption decisionsxxiv.
Hence, understanding both the contextual and personal
drivers of technology adoption behaviour is of utmost
importance in designing effective interventions for small-
holder farmers in order to support them to adopt good
farming practices, while also aiming towards earning a
living income and preserving biodiversity.

4 To protect forests and biodiversity, all drivers of deforestation
should be addressed simultaneously
7 The Consumer Goods Forum (CGF) pledge to zero net deforestation 2010, New York Declaration on Forests 2014, Amsterdam Declaration towards Eliminating
deforestation from agricultural commodity chains with European countries 2015, Cocoa and Forests Initiative 2017, European Commission 2019 Communication to
step up action against deforestation and to restore forests (EU 2019).
Smallholder commodity production is connected to
deforestation, but increasingly, large-scale indus-
trial agriculture for domestic urban consumption
and exports are drivers of deforestation.
Globally, 27% of all forest disturbances result from
commodity-driven deforestationxxv. However, the common
view that growing populations of shifting cultivators and
smallholders are the main drivers of deforestation has
been false, as large-scale industrial agriculture for domes-
tic urban consumption and agricultural exports is increas-
ingly the primary driver of tropical deforestationxxvi. In
Côte d’Ivoire, our studies showed that between 40 and
58% of cocoa farms had been cleared from primary forest,
and 25 to 33% established on fallow land, with farms on
average 21 years oldxxvii.
Deforestation, environmental and land degradation
attributed to smallholder farmers is driven by many
factors.
Deforestation worldwide is an important cause of green-
house gas emissions contributing to climate change, and it
can create a local loss of ecosystem services and natural
capital. However, smallholders convert forests to agricul-
tural land (to expand farmland or compensate for decreas-
ing productivity on existing farms) and degrade forests
through unsustainable exploitation, such as for timber,
fuel, foods and medicines for subsistence use and in-
comes. These local benets can be weighed against the
costs of access and social and institutional barriers that
determine people’s use of and impact on a resourcexxviii.
These impacts change over time, as well. There has been
a tendency to identify ‘universal’ drivers of deforestation
(or what may stop it). Population, wealth (or conversely
poverty) and market access are considered major drivers
of forest lossxxix.
There are many new commitments to stop deforest-
ation – but these are often blind to multiple drivers,
failing to address them or addressing outcomes
instead of causes.
By 2018, over 450 commodity traders and retailers had
committed to voluntary sustainability certication, made
individual corporate commitments and programmes and
signed pledges and regional and international public sector
agreements7 to reduce or eliminate the deforestation
caused by their commodity value chainsxxx. However, many
of these commitments fail to consider that the dynamics
of forest loss and recovery are driven by many political
and socio-economic contexts and forces, interacting at
global to local levels and over timexxxi. These interactions
mean that interventions to mitigate deforestation by
smallholder farmers can play out very differently, depend-
ing on local (historical) contexts. Even actively policed
boundaries are easily encroached when other factors allow
or encourage it, when access to managed forests is
misusedxxxii or when land ownership claims overlapxxxiii.
Similarly, payments for ecosystem services can be cap-
tured by elitesxxxiv, leaving poor smallholders even more
dependent on forest resources. The evidence base on the
most effective measures to stop deforestation is still weak
and scattered. What works or not is very much context
dependent.
Improved farm productivity in elds close to forest
areas does not necessarily reduce pressure on
forests.
Many studies indicate that in addition to local yield
increases, measures to prevent agricultural encroachment
into forests are essentialxxxv. Productivity improvement can
encourage deforestation when commodities have elastic
demand on the short term (i.e. when supply increases,
their prices do not decrease)xxxvi, situations that are
common in cocoa, palm oil, soy and timber, but also in
local charcoal and wood fuel value chains. Additionally,
creating economic opportunities through improved
productivity can attract migrants, which further contrib-
utes to forest encroachmentxxxvii. When farmers are
capital- and/or labour-constrained, productivity intensi-
cation can release labour and allow farmers to expand
cultivated farm areas.
Protected areas – when well-managed – can reduce
deforestation, but often do not stop forest

approaches protecting forests, while also taking into
account the local context and needs for regulated forest
access and use. Such approaches are likely the most
successful for stopping or reducing forest degradation and
deforestationxxxix.
Various interventions tested for restoration, but the
role of smallholders in restoration is unclear.
While there are cases of forest restoration, efforts to
implement restoration promises generally have been slow
to gain traction, with most restoration taking place outside
of natural forests, and the role of smallholders in restora-
tion is unclearxl. Collaborative interventions include
encouraging diverse agroforestry systems, sustainable
agricultural intensication, promoting the use of degraded
lands, cash-for-work programmes, incentivised grants and
loans to smallholders while adjusting or removing per-
verse incentives from subsidies and, lastly, establishing
national forest restoration fundsxli.
The most effective means of addressing the causes
of deforestation appears to be multiple simultane-
ous interventions.
Evidence concerning the most effective solutions to stop
commodity-driven deforestation suggests the importance
of several initiatives implemented simultaneously: strong
enforcement of forest protection laws; support of contin-
ued forest management by local people, including legal
rights; payments for ecosystem services (PES) that
increase the economic value of forests to local people,
while reinforcing their intrinsic motivation to protect the
forest; and timely national action, rather than lengthy
international agreementsxlii. Stopping PES runs the risk of
resuming deforestation behaviour—or worse. Without
monetary value, the forest may suddenly become worth-
less, whereas before PES was established, forests’ multi-
ple intrinsic, social and economic values became ‘forgot-
ten’ or ‘overruled’ by PES monetary value. Kerr et al
8 Leakage: the ‘net increase of greenhouse-gas emissions in an area outside the project resulting from the [project] activity’ (Schwarze et al., 2002). It occurs
‘whenever the spatial scale of intervention is inferior to the full scale of the targeted problem’ (Wunder, 2008). This denition also applies to deforestation itself next
to for greenhouse-gas emissions resulting from deforestation.
(2017) clearly shows that incentives that undermine
intrinsic sources of motivation are able to crowd-out
targeted behaviour, while incentives that reinforce intrinsic
sources of motivation can crowd it in.
Multi-stakeholder collaboration is needed taking
into account leakage and spill-over effects of
interventions.
The implementation of multiple and simultaneous inter-
ventions requires multi-stakeholder collaboration. As
many of the compliance mechanisms associated with
implementing zero deforestation initiatives are costly,
these may be overwhelming or inaccessible for smallhold-
er farmersxliii. This should be addressed. Land use policy
change furthermore needs to take account of leakage8 and
spill-over effects of interventions. For example, policies to
reduce soy-related deforestation in the Brazilian Amazon
appeared successful, but deforestation increased in the
Cerradoxliv. Additionally, high compliance costs in regions
where zero deforestation commitments are implemented
could result in a loss of competitive advantage, encourag-
ing further leakage to other localitiesxlv.
Such collaborations should include appropriate
baselines, monitoring and evaluations.
Appropriate baselines are needed in order to compare the
results of interventions in landscapes where different
communities, ethnic groups or land uses occur. Especially
for landscapes with different commodities and where
organisations implement different programmes, the
overall effect on deforestation may be assessed, but the
effects of specic interventions are difcult to untangle.
Reporting on the progress of zero deforestation initiatives
is scarcexlvi, and on-the-ground impacts that can be
attributed to these initiatives are limited at best. The New
York Forest Declaration ve-year assessment reported few
positive results and slow progressxlvii. As baselines and
monitoring activities often go beyond what are perceived
as private sector activities and spheres of inuence,
partnerships with public sector, civil society, research
organisations and service-providing organisations—such
as the World Resources Institute’s Global Forest Watch
and the Sustainability Consortium (TSC) (Curtis et al
2018)—are essential in enabling the tracking of impact of
zero deforestation initiatives, if implemented properlyxlviii.

5 Structural change is essential for all smallholder commodity
farmers to earn a living income
One highly important structural change is land
reform, to ensure that farm sizes increase.
Our research shows that often, farm sizes in cocoa and
tea producing countries are much smaller than so-called
‘sustainable farm sizes’, i.e. farm sizes needed to earn a
living incomexlix. Increasing farm size is a path worth
exploring. However, this is often not an option, as most
land is already occupied and buying land is costly. Labour
requirements to create new farms are expensive and have
led to different share cropping arrangements between
farmers and workers, where a proportion of the harvest or
land is shared, known as abunu, abusa and abunal.
Farmers may start by receiving a small piece of land in
return for their labour. Thus, increasing farm land can
typically only happen in forested areas, which are often
formally owned by the government. Also, inheritance laws
lead to land fragmentation. To increase farm sizes there-
fore, a large transition is needed, in which one segment of
farmers would increase their farm sizes and another
segment of farmers would stop their farming altogether,
consequently seeking employment opportunities outside of
agriculture. Lessons for this transition can be learned from
historical examples of agricultural land reform processes
in Europe and elsewhere. Scaling up smallholder farming
requires the deep involvement of public sector, civil
society and private sector playersli.
Land reform requires adequate employment oppor-
tunities for farmers moving out of agriculture.
While land reform poses opportunities to increase farmer
income for some, it also poses a challenge for other
farmers who can no longer grow cocoa or tea. In order to
create space for larger farms that can generate a higher
income, other farmers need to nd employment else-
where. Some farmers can continue in the agricultural
sector, either as employees of larger farmers or elsewhere
in the agricultural value chain, in processing, trading or
service activities. As farm sizes increase and farmer
revenues increase, more investment in added value
activities in the value chain is possible, thereby generating
employment for farmers that had to quit farming. Other
employment opportunities could be found outside of
agriculture, mainly in larger towns and cities. Already
now, we understand that many young people in rural
areas of developing countries leave the countryside since
they no longer see a future in farming. This is presents
signicant challenges that governments and cities are
already trying to address.
Structural changes are not new in rural develop-
ment thinking, but broader policies are needed, and
multiple stakeholders should collaborate to imple-
ment them.
Even in the 1970s and 1980s, similar changes were
proposed, such as the ‘integrated rural development
policies’ which were also focused on moving away from
small-scale agriculture. They strongly suggested increas-
ing local agro-processing in order to, among other things,
create more local employment opportunitieslii. An impor-
tant lesson learned from these policies was that they were
less effective when scaled up to the national level, as this
no longer allows communities to mobilise their own
resources for development or for real strengthening of the
development of local public sector agenciesliii. Some major
differences between then and now include the movement
away from rural thinking towards urban development and
job creation. More important is the change in responsibili-
ties from the public sector only to a shared collaboration
between the public and the private.
Price increases lead to short-term benets for
farmers, but increases could have negative long-
term effects on the market, which could lead again
to pressure on prices.
Price interventions in global markers often have limited
effects when they are only applied at the country or
regional level. If prices are raised by individual country
policies, buyers of cocoa and tea can purchase cocoa and
tea in other countries instead, where prices are lower.
Moreover, raising cocoa and tea prices will lead to more
farmers growing them and spur existing farmers to
increase production. This puts more pressure on forests
for land expansion. If no policies are implemented to
mitigate such effects, total volume produced will increase,
creating national and global surpluses. This may lead to
farmers not being able to sell their cocoa, thereby reduc-
ing their incomes and causing market prices to fall again.
An example here is the Brazilian coffee sector where ‘at
various times during the last century, (1906, the 1930s
and the early 1970s) the coffee giant had to destroy many
millions of bags of green coffee [] to prevent a glut in the
market’liv.
The living income differential in Ghana and Côte
d’Ivoire seems to be a good solution, but could it
also backre?
The recent living income premium (called ‘living income
differential’) set by Ghana and Côte d’Ivoire is intended to
help increase incomes of farmerslv. As both countries
together are responsible for two-thirds of global cocoa
production, this premium may in the short term have no
Wageningen Economic Research | White paper on sustainable commodity production 14
effects on cocoa sales. But in the long term, effects as
described in the previous paragraph could materialise.
This development is likely to inspire buyers to see whether
they could buy their cocoa for a lower price elsewhere.
This may also increase the global market price for cocoa
to which farmers in other countries respond by planting
more cocoa. Such demand and price increase could spike
cocoa production and sales in for instance Brazil and
Indonesia, with severe repercussions:
lower cocoa sales for Ghanaian and Ivorian farmers,
leading to income decreases which could counteract
earlier increases
massive unsold cocoa stocks at public sector level in
Ghana and Côte d’Ivoire, leading to pressure on public
sector budgets because farmers are paid while the cocoa
cannot be exported.
So, without other policies in place to address such volume
and budget challenges, price levels established by the
public sector are bound to have negative effects.
A precondition for increasing prices without creating
negative effects is a system of international supply
management, led by producing countries.
Since the cessation of international cocoa agreements in
the mid-1980s, among which included export quotas,
beans have been traded internationally in a free market.
This resulted in a period of low prices throughout the
1990s. To cope with the collapse of prices and with a
value-sharing scheme that is considered unfair, Koning
and Jongeneel suggested in 2008 the creation of a ‘cocoa
OPEC’ among the main producing countries. The idea was
‘parked’ as prices of raw materials including cocoa in-
creased between 2008 and 2015. However, in response to
the recent price fall and with the voluntarism of the
African public sectors, whose economies were directly
affected, the creation of an ‘OPEC for cocoa’ is explicitly
mentioned in the declaration of the last conference of the
International Cocoa Organisation (ICCO, April 2018). The
World Bank, in its latest report on Ghana (2018), also
stresses the need to strengthen cooperation between
Ghana and Côte d’Ivoire as prerequisite to gaining more
market power. If such international supply management
system is developed, it should be led by producing
countries, who involve farmers and their organisations,
include production controls in a fair and efcient way, and
prevent countries from free ridinglvi. For a 10-step action
plan to implement this, see Koning & Jongeneel (2006),
and Koning & Jongeneel (2008)lvii.
Policies should consider climate change forecasts,
as it is expected by 2050 that in many regions it will
be difcult to produce tea, cocoa and coffee.
Recent studies show that climate change is expected to
make large parts of cocoa and tea and coffee growing
areas much less suitable for growing these cropslviii. In
some areas, growing these crops will no longer be possi-
ble without far-reaching adaptation activities. To address
these issues at farm-level, farmers can plant improved,
more climate-resilient varieties or develop infrastructures
for irrigation. However, these strategies often require
substantial investments, which many smallholder farmers
do not have readily available. Irrigation infrastructure also
goes beyond farm scale, as it requires fair and wise
management of scarce water resources, not only between
farmers, but also between farming and other sectors.
Predicted climate impacts on cocoa and tea productivity
therefore also require regional or landscape approaches
which design policies that address all the consequences of
climate change for one area.
In some areas, growing these crops
will no longer be possible without
far-reaching adaptation activities

This requires supporting farmers in affected areas
to change land use entirely in order for them to earn
a living income, by actors needing to provide differ-
ent services to the farmers than in the past.
In areas affected by climate change, farmers can be
supported in diversifying their income-generating activities
to complement the income from tea or cocoa, or they can
be facilitated in shifting from cocoa and tea as their main
source of income to other crops or income-generating
activities. Interventions to address climate change should
more often facilitate the latter instead of keeping farmers
in the production of crops which their land will no longer
be suitable for in the future. By considering projections for
the future, the public and private sector try not only to lift
farmers out of their poverty, but also make sure they stay
out of poverty. This requires that the public sector and
service deliverers work differently; tea and cocoa coopera-
tives would support their farmers in producing other crops/
livestock, providing technical assistance and inputs not
only for cocoa and tea, and facilitate farmers in marketing
the new products. Thus, public sector agencies, service
deliverers and buyers implementing programmes with the
farmers would need to diversify their support as well.
Diversication can contribute to income, resilience
and improved nutrition, but is not suitable for all
farmers.
Diversication can help farmer to increase their total
income, while improving their resilience by reducing their
reliance on a crop. Moreover, diversication can help
farmers increase the diversity in their diets, contributing
to greater balance and nutrition. Earning additional
income through diversication is not always possible for
all farmers, however. This is only possible when there is a
market for these products or activities. This can prove
difcult in remote, sparsely populated and relatively
inaccessible rural areas. Market development should be
supported alongside supporting farmer diversity, focusing
on improvements in nutrition, in addition to increasing
incomes. Moreover, many cocoa and tea farmers have
small farm sizes, which limits the land available to diver-
sify their income. Finally, many cocoa and tea farmers lack
the resources to invest in developing new economic
activities; therefore, income diversication is more
suitable for farmers with enough assets.

6 What public and private sectors can do: conclusions and
recommendations for lifting smallholder commodity farmers out
of poverty and protecting forests and biodiversity
The poorest smallholder commodity farmers need
different policies for earning a living income than
relatively better-off farmers.
For the poorest farmers to earn a living income, manifold
increases in income would be required, which is not
feasible given farmers’ situation in terms of land size and
productivity levels, not to mention given how the market
currently operates. We identify the structural changes that
can facilitate increases in income of the poorest commod-
ity producers:
1 Land reform policies should seek to increase farm sizes.
This is impossible without farmers moving out of
agriculture, who need to be properly supported to nd
alternative income sources. The land reform process
should ensure that no human rights are violated. And
should address inheritance laws.
2 Land reform policies should be informed by climate
change forecasts (as in some areas tea or cocoa may
not grow anymore), urbanisation and other demographic
trends.
3 Price increases seem a viable option, and could lead to
income increases for farmers, but they also could have
negative effects on the market over time, leading to
buyers changing sourcing countries and surpluses,
putting pressure on market prices yet again. Also, price
increases on their own are not enough to lift the poorest
farmers out of poverty. Price increases thus must go
hand in hand with land reform policies.
4 A precondition for increasing prices without creating
negative effects is a system of international supply
management led by producing countries. Furthermore,
farmers and their organisations should be involved in
this system, which should include production controls in
a fair and efcient way and prevent countries from free
riding. For a 10-step action plan to implement this
system, see Koning & Jongeneel, 2006, and Koning &
Jongeneel, 2008lix.
Support in productivity increase and on-farm diver-
sication can be useful for relatively better off
farmers under certain conditions.
Interventions to increase commodity productivity, along
with support of on-farm diversication focused on income
increase and food security, can be useful in some cases,
but only under the following circumstances:
1 The intervention targets the right group (farmers who
earn enough to invest, and have a large enough farm
size).
2 The aspirations, needs, opportunities and behavioural
drivers of farmers are taken into account via a farming
systems approach that does not focus solely on com-
modity production.
3 The intervention should be informed by climate change
forecasts and market developments in order to ensure
the intervention is ‘future proof‘. This could mean that
farmers are supported to change their land use entirely
to continue earning an income in the long run. Such
land use changes should be informed by possibilities in
marketing the produce.
In addition to the above conditions for success, land
reform and price increases can also help to improve
incomes of these farmers.
To protect forests and biodiversity, all causes of
deforestation need to be addressed simultaneously
through multi-stakeholder collaboration.
By all accounts, the most effective strategy for responding
to all causes of deforestation is multiple interventions at
once. Such interventions should be implemented through
multi-stakeholder collaboration, including conducting
appropriate baselines and taking into account leakage and
spill-over effects.
Learning from each other: sharing positive and
unsuccessful experiences data and methodologies
to design effective and efcient interventions.
For designing effective and efcient interventions, ndings
should be shared between countries and across commodi-
ties on what works and also what failed to work. This
includes the sharing of data and methodologies in order to
avoid too much data being collected too many times, with
too many farmers being interviewed too often, to satisfy
the needs of various buyers and implementers. Much data
has been collected in the past but has remained conden-
tial. We call on the private and public sectors as well as on
NGOs and business platforms to nd a way to share data
and methodologies without jeopardising business and
public interests. A good example is the Cocoa Soils
Initiative, https://cocoasoils.org/.
Please nd detailed steps that we propose to be under-
taken for smallholder commodity farmers to earn a living
income and for forest and biodiversity protection in
Appendix 2.
By all accounts, the most eective
strategy for responding to all causes
of deforestation is multiple interventions
at once

7 Research agenda to support structural transformation:
a need for transformational science to facilitate
smallholder farmer sustainable development
How can the private and public sectors collaborate more effectively with
academics to lift smallholder farmers in commodity sectors out of poverty
and support forest protection/reforestation?
A research agenda to positively transform smallholder commodity farming
Farming system research acknowledging community
and landscape scales
The dramatic change from the common private sector data
collection focus on individual commodity purchases means
that we should take a farming and household system
approach. This is to understand why and how farmers
make choices for different cash and subsistence crops,
livestock and on and off farm activities and land uses –
and, by extension, the tradeoffs between different crops
and business models. This change ts with a living income
approach, acknowledges the role of labor and technologies,
and it seeks to provide data that can support efforts to
increase total disposable income as well as food and
nutrition security. This information can also help us
understand the implications of how interventions that focus
on deforestation and environmental degradation have an
impact.
Better understanding of farmer’s aspirations, assets
and capacities
Better understanding the combination of farmer’s aspira-
tions, needs, knowledge, assets and capacities is of utmost
importance. This is a change from the current practice of
‘sending messages’ through interventions, towards
listening to farmer’s household and individual members
changing needs and how farmers can benet from the data
they help generate. This implies a focus on contextually
applied recommended agricultural practices rather than
meeting (externally set) standards.
Pathways to transforming farming systems, markets
and landscapes
We must investigate and understand what it takes to
(further) develop and diversify smallholder commodity
products, markets, and processing facilities such that more
added-value remains in the country of origin and with
farmers and labourers in commodity value chains. It is
additionally important to grasp the motives of farmers to
expand in forested areas and the political reality driving
such expansion. Trade-offs and implications of maintaining
the value of sensitive and high-risk and high conservation
value landscapes must be fully accounted for, in response
to zero deforestation concerns and initiatives.
New research models focusing on commodity
farmers and sectors are needed.
To meet the challenges addressed in this paper, the
questions asked by scientists, private and public sector
organisations and other stakeholders need to be critically
reviewed, in addition to the fundamental ways that
science is conducted, how scientic outputs are produced
and, last but not least, for whom. Different models of
conducting and disseminating research inform the sectors
and value chains in which smallholder commodity farmers
operate, ranging from academic to in-house corporate to
origin state research. These different models (see
Appendix 3) result in scientic outputs accessible to
different users in very different formats. As the commis-
sioners of scientic research vary, each model functions
according to different agendas often meeting different
aims, covering different geographic and political scales.
There are two clear disadvantages of these parallel,
multiple models of science.
One disadvantage is that despite the decades of research
into smallholder commodities such as tea, coffee and
cocoa, scientic knowledge has not effectively reached
farmers, or wider farm and ecosystem products and
services, in a way that could substantially change their
position in these commodity value chains. Science has
focused on and beneted other actors in smallholder
commodity value chains, particularly those commission-
ing, funding and consuming the products. Second is that
the lack of signicant changes in livelihood indicators such
as incomes and degradation in many environmental
indicators (trees on farms, forest cover, soil and water
quality), strongly points towards ineffectiveness when
gauging how scientic knowledge and research models
have impacted smallholder farmers.
Future research approaches should address the
complex make-up of smallholders.
Most of the publicly accessible research is deeply divided
by language, sector and geography, thereby hindering
cross-regional and cross-commodity sectoral learning and
exchange. This is despite many actors conducting science
work on multiple commodities. Currently, most research
is predominantly structured according to disciplines.
Wageningen Economic Research | White paper on sustainable commodity production 18
By contrast, highly complex challenges with many trade-
offs require more inter- and multi-disciplinary approaches,
where the vast body of crop production research is
integrated with economics, politics, livelihoods (incomes,
health, labour etc.), communication, innovation and
technology.
A research agenda for inclusive, resilient smallhold-
er commodity value chains.
Taking these issues into account, the cocoa sector created
a consensus on societally relevant research needslx.
Building on this history, we propose a research agenda
that addresses knowledge gaps in order to positively
transform smallholder commodity farming (see the box
above). This agenda requires taking an integrated,
multidisciplinary, international and collaborative approach
to research. This could take a more co-designed approach
to design, implement and disseminate research. This
entails developing collaborative research models investi-
gating options and approaches to funding, generating and
ownership of data and results between farmers, farmer’s
organisations, traders, manufacturers, researchers and
other stakeholders. It also means engaging smallholder
farmers and origin country public sector agencies in the
co-design of research, and in making co-generated
knowledge outputs much more available, if they are to
adequately respond to the issues addressed in this paper.
By engaging with public sector agencies, additionality is
created, even in so-called weak stateslxi. Equally, voluntary
sustainability standard systems largely implemented by
the private sector have increasingly realised the benets
of collaborating with NGOS and public sector authorities
– initially as trainers as in Côte d’Ivoire in the cocoa
sector, but increasingly as partners. These private volun-
tary certication schemes have sparked reactions by origin
country public sectors claiming back sovereignty over their
territory and the welfare of their inhabitants, the commod-
ity producing smallholders. The joint action by Ghana and
Côte d’Ivoire to create a living income differential is one
example. The mandatory and gradually rolled-out certi-
cation schemes recently introduced for palm oil cultivation
by public sector organisations in Indonesia and Malaysia is
another example. A third is the Mozambican national
biofuel certication in response to EU biofuel
certicationlxii.

Way of calculating what percentage of farmers is
placed in which income group.
Group 1: Consists of farmers who earn less than the World
Bank poverty line of 1,90 USD per person per day. This
excludes farmers who, with a 10% increase in total
household income earn the same or more than the World
Bank poverty line of 1,90 USD per person per day.
Group 2: Farmers who earn minimally as much as the
World Bank poverty line of 1,90 USD per person per day,
and maximally below the living income benchmark. This
includes farmers normally placed in group 1, but who,
with a 10% increase in total household income earn the
same or more than the World Bank poverty line of 1,90
USD per person per day.
Group 3: Farmers who earn the same or more than the
living income benchmark per person per day.

The monthly living income benchmarks were converted to
the year of each dataset using the changes over time in
the consumer price index. The living income benchmark is
based upon a country specic average family size (6 in
Côte d’Ivoire, 5 in Ghana, 5.5 in Kenya). Therefore, yearly
household income from each of the datasets was adjusted
only for the period: it was divided by 12 to change the
data from yearly to monthly income. For comparison with
the World Bank poverty line, the monthly living income
line per family was converted to a daily living income per
household member. By doing so, we treated adults and
children in the households in the same way, not correcting
for male or female equivalent FTE values.
Poverty line benchmark calculations
For each country, household incomes were converted to
match the poverty line of $1.90 per person per day. This
poverty line was set in 2011, and was adjusted to the year
of the data using the difference in time using the consum-
er price index. The yearly household level income data
was converted to daily income by dividing by 365, and
then divided by the number of household members.

Appendix 2: detailed steps to be undertaken for smallholder
commodity farmers to earn a living income and for forest and
biodiversity protection
Action Approach Involved stakeholders
Land reform • Start a land reform process to create new land use
policies, which leads to farmers to move out of
agri culture to make it possible for remaining farmers
to earn a living income. Such a process should be
inclusive, discussing needs and possibilities with
the affected population. And should address
inheritance laws.
• Provide alternative income earning opportunities for
people moving out of agriculture by for instance
establishing arrangements so they can become
absentee land owners. Ensure that human rights are
not violated in this process.
• In creating new land use policies, consider climate
change forecasts and demographic trends such as
urbanisation, and forest and biodiversity protection
targets.
• Investigate what alternative livelihoods could be if
expected climate change effects materialise,
including conducting land suitability analyses, and
studying the feasibility of new market/supply chains.
• Learn from similar land reforms processes and
effects in Europe.
• Next to land use policies, such land reform process
should also lead to policies for protecting forests and
biodiversity considering the lessons learned in this
paper.
• The public sectors in origin countries are in the
driver’s seat of land reform processes.
• The private sector to support the origin country
public sector to implement such land reforms as they
are an important stakeholder for the origin country
(export revenues), and they can also continue
sourcing from the country without being accused of
violating human rights.
• EU public sector organisations to support origin
public sector organisations in learning about land
reform policies implemented in the past.
Inuencing the market and
farm gate price
• Governments to establish the market price for a
commodity together, in collaboration with farmers
and their organisations, but only if they can avoid
surpluses in the production of the commodity.
• Quota systems could be used, but the question is
based on what criteria it will be decided who get
what quota, as quotas are generally exclusive, not
inclusive. Would non-cocoa producing countries still
have the possibility to produce cocoa? Lessons could
be learned on whether an OPEC is possible for cocoa
based on the 10-step plan developed by Koning and
Jongeneel (2006 and 2008).
• Buyers to close long-term contracts with sustainabi-
lity performance criteria connected to higher prices
for a commodity. However, the performance criteria
should be possible to achieve by the farmers without
them taking all the risk.
• Public sector organisations in origin countries
The private sector to nd creative ways in the value
chain together, e.g. by reducing cost, to optimise the
price paid to smallholder farmers.
• Consumers should (be enticed to) pay more for
chocolate.
Capacity development of
remaining commodity
producing farmers to
increase productivity and
quality and increase
incomes
• Support remaining farmers in climate change
adaptation (e.g. drought resistant clones), and
enhancing productivity and quality through training
and input supply, etc.
• This support should be done while considering the
whole farming system and contextual and personal
factors to optimise the possibility to inuence
farmers and households to change their behaviour
and have an impact. This support should include
nding ways how to overcome a period with less
income due to replanting bushes/trees with new
clones, without the farmers to take all the risk.
• Companies can support farmers from which they
source--especially when farmer unions have a voice.
• Whole farming system approach does not seem to
suit commodity buyers but it may be needed for
them to continuing sourcing cocoa or tea.
Forest and biodiversity
protection
• Address multiple drivers of deforestation/biodiversity
loss simultaneously.
• Properly implemented multi-stakeholder collabora-
tion, including conducting baselines and considering
leakage and spill-over effects.
• The public sector in origins together with the private
sector and NGOs.
Learning from each other:
sharing positive and
unsuccessful experience
and data and methodolo-
gies
• Sharing learnings between countries and across
commodities of what works and also what failed to
work.
• Sharing data and methodologies in order to avoid
too much data to be collected multiple times and
too many farmers to be interviewed too often.
• The private sector, the public sector, standard setting
bodies, NGOs.
• Universities: a good example is the Cocoa Soils

i The Economist (2017): ‘In economic terms, commodities are vital
components of commerce that are standardised and hence easy to
exchange for goods of the same type, have a fairly uniform price around
the world (excluding transport costs and taxes) and help make other
products. They are extracted, grown and traded in sufcient quantities
that they underpin highly liquid markets, often with futures and options to

... These ecological zones (i.e., the shaded part of Figure 1) include the Ashanti, Brong-Ahafo, Central, Eastern, Volta and Western regions (refer to Abubakar, RM&E (COCOBOD), pers. communic., 2016, cited in Waarts et al., 2019). It is worth noting that some of these regions have been politically repartitioned, demarcated and renamed in 2018-2019. ...
... The WCF's social dimension of sustainability may be understood as healthy, thriving cocoa farmer households and communities working under naturally acceptable conditions and being granted equal opportunities. The social side also seeks to empower farmers to make rational decisions about their welfare, farms and produce (see Waarts et al., 2019) without any discrimination. Lastly, the environmental dimension of sustainability refers to responsible and sound environmental stewardship in cocoa-farming communities where the environment is well protected from the destruction caused by open-cast mining and logging activities (Basir-Cyio et al., 2020;Kouassi et al., 2021). ...
... The Ministry of Finance announces the new price at the commencement of a new crop season (Abubakar, RM&E (COCOBOD), pers. communic., 2016, as cited in Waarts et al., 2019) and farmers and other key stakeholders continue their upstream CSC activities. An industry-wide lack of transparency seems to culminate in systemic corruption, pilferage, diversion of farm inputs, resource misappropriation and mismanagement (as narrated by the respondents in Section 4.1). ...
Purpose Change in the economic status of a low-income country is accompanied by an expected increase in investment and economic activities along with land degradation and biodiversity loss. This study aims to explore Ghana's transition from a low-income to a lower-middle income economy, and the impact of the accompanying rise in extractive activities on the upstream cocoa supply chain (CSC) and its supporting ecosystem. Design/methodology/approach The author conducted interviews and made critical observations on Ghana's upstream CSC. Grounded theory (GT) and system dynamics (SD) methodologies were employed to extract and analyze themes from the data gathered. Causal loop diagrams were derived from the analyzed data to provide insight into the possible long-term structural behavior of the upstream CSC due to the change in Ghana's economic status. Findings The findings suggest that continuous increase in land capture by open-cast mining and logging concessionaires, poor environmental law enforcement and farmer discontentment could cause a decline in cocoa production and biodiversity. Originality/value This research could stimulate the identification of a most effective alternative policy (such as agroecological farming) to improve the living standards of upstream CSC partners and reduce biodiversity loss. The models herein could serve as a learning/demonstration tool for researchers, academia and policymakers when brainstorming students, or during stakeholder (community/society) engagement/consultation sessions, to discuss policy decisions and their consequences. The model approach could also be helpful when designing strategic land-use policies. This could improve understanding of the complex interdependent relationships and the consequences of land degradation, loss of biodiversity and rural livelihood from a system thinking perspective.
... Despite past and current interventions to lift smallholder African cocoa farmers out of poverty, most live below the living income standards. Approximately 80% and 75% of cocoa farmers in Ghana and Cote d' Ivoire, respectively, live below the living income standards for the specific countries (Waarts et al 2019). Living income is the net income a household would need to earn to enable all household members to afford a decent standard of living. ...
... Living income is the net income a household would need to earn to enable all household members to afford a decent standard of living. For more than half of the cocoa-growing households, household income would need to double for them to earn a living income (Waarts et al 2019). For cocoa-growing households in SSA, an increase in income can be achieved either through; 1) increasing the cocoa farm gate prices, 2) improving cocoa productivity, 3) diversification with other crops and off-farm activities and/or, 4) value-adding cocoa at the small-scale level. ...
... Increasing farm-gate prices for these commodities is necessary but not sufficient to lift smallholder farmers out of poverty. Even if farmers' incomes from these commodities were to directly increase -for example, through increased farm gate prices -small farm sizes and low productivity levels lead to only a few farmers moving to another income group (Waarts et al 2019). ...

Key highlights 1 Cocoa and coffee contribute significantly to economies of African countries and the livelihoods of smallholder farmers through revenues and employment; 2 Massive inequalities exist in the distribution of returns within the global value chains of cocoa and coffee. West African farmers only receive 7% of total global cocoa proceeds despite producing 75% of the world's cocoa beans. Coffee producing countries only receive 10% of aggregate coffee wealth globally. Value addition of these commodities within Africa is needed to tap into proceeds from processing and distribution as well; 3 Contributions of cocoa and coffee systems to human capital in terms of nutrition and health are mixed and context-specific. Pesticides and fungicides pose a severe threat to human health from these systems. Contributions to human nutrition largely depend on the farm's diversity and incomes from commodities produced. Freeing the cocoa industry of the negative stigma of child and enslaved labour remains a challenge; 4 Sustainable intensification and diversification through agroforestry are needed to combat the negative impacts of cocoa and coffee production growth in forest frontiers. There is evidence that some of these are beginning to take root; 5 Production, market and policy innovations will be needed to improve cocoa and coffee contributions to livelihoods in Africa, especially in terms of financial, human, natural and social capital.
... Within a food system, contextual factors (shown in Fig. 3) and personal factors, can strongly differ between farmers and geographies (van Berkum et al., 2018;Waarts et al., 2019). These factors have important implications for farmers' income from agricultural production and off-farm activities, which is why we present the two figures additionally to the food systems figure above as it deepens the information for food system components which are important for tree-crop commodity farmer income. ...
... Some of the key recurring barriers to behavioural change are: 1) Farmers might not be able to afford the financial investments that are required for technological innovations, or might decide to invest in something else, 2) The future benefits of investments are not guaranteed, 3) Failing markets lead to adoption constraints (i.e. shortage of inputs when needed), 4) Interventions may not be tailored enough to farmers' specific needs and possibilities (Waarts et al., 2019). Interventions that address these barriers are therefore more likely to lead to behavioural change of farmers and therefore positively impact incomes. ...
... Frequently, interventions have been implemented from a technocratic perspective which does not consider personal factors. Studies have shown that these factors influence farmer and household decision-making processes (Waarts et al., 2019). Personal factors include socio-economic Fig. 2 The food system, its drivers and outcomes. ...

Many sources indicate that smallholder tree-crop commodity farmers are poor, but there is a paucity of data on how many of them are poor and the depth of poverty. The living income concept establishes the net annual income required for a household in a place to afford a decent standard of living. Based on datasets on smallholder cocoa and tea farmers in Ghana, Ivory Coast and Kenya and literature, we conclude that a large proportion of such farmers do not have the potential to earn a living income based on their current situation. Because these farmers typically cultivate small farm sizes and have low capacity to invest and to diversify, there are no silver bullets to move them out of poverty. We present an assessment approach that results in insights into which interventions can be effective in improving the livelihoods of different types of farmers. While it is morally imperative that all households living in poverty are supported to earn a living income, the assessment approach and literature indicate that focussing on short- to medium-term interventions for households with a low likelihood of generating a living income could be: improving food security and health, finding off-farm and alternative employment, and social assistance programmes. In the long term, land governance policies could address land fragmentation and secure rights. Achieving living incomes based on smallholder commodity production requires more discussion and engagement with farmers and their household members and within their communities, coordination between all involved stakeholders, sharing lessons learnt and data.
... Further, the production of tree-sourced foods with international market potential can increase employment and business opportunities in rural areas, which in turn can reduce rural-to-urban migration (Deotti & Estruch, 2016). Diversified employment opportunities can further be generated by accompanying increased production of tropical tree-sourced foods with investments in the creation of value adding activities to the products (Waarts et al. 2019). Tree-based food production can thus provide opportunities for gender empowerment, improve equitable and sustainable development options, and provide more resilient livelihood options, depending on local culture and gendered tenure rights to land and trees (Ingram et al., 2015; Table 3). ...
... Tree-plantations in monoculture on the other hand, can have negative effects on water security, by negatively affecting groundwater recharge (Jackson et al., 2005), and increase vulnerability of smallholders to price fluctuations, climate change and pandemics (Waarts et al., 2019;Kahiluoto, 2020). Thus, if scaling-up of tropical treebased food production is primarily based on monoculture plantations, the environmental, livelihood and nutritional benefits that can be obtained are limited. ...
... Supply to global markets can in some cases, depending on the crop, be associated with rapid transformation of traditional production systems towards industrialized monocultures, which, as discussed above, can reduce the environmental, nutritional and livelihood benefits of tree-based food production. In addition, many (traditional) smallholders lack the financial means or labour capacity to invest in new production models necessary to supply the global market or cannot bear the risks that involve these new investments (Waarts et al., 2019). If powerful actors and largescale farmers then take over and replace small farms, this can increase inequality and potentially exacerbate poverty (Altieri & Nicholls, 2008;Brown & Sander, 2007;Markelova et al., 2009). ...

1. The global food system is causing large-scale environmental degradation and is a major contributor to climate change. Its low diversity and failure to produce enough fruits and vegetables is contributing to a global health crisis. 2. The extraordinary diversity of tropical tree species is increasingly recognized to be vital to planetary health and especially important for supporting climate change mitigation. However, they are poorly integrated into food systems. Tropical tree diversity offers the potential for sustainable production of many foods, providing livelihood benefits and multiple ecosystem services including improved human nutrition. 3. First, we present an overview of these environmental, nutritional and livelihood benefits and show that tree-sourced foods provide important contributions to critical fruit and micronutrient (vitamin A and C) intake in rural populations based on data from sites in seven countries. 4. Then, we discuss several risks and limitations that must be taken into account when scaling-up tropical tree-based food production, including the importance of production system diversity and risks associated with supply to the global markets. 5. We conclude by discussing several interventions addressing technical, financial, political and consumer behaviour barriers, with potential to increase the consumption and production of tropical tree-sourced foods, to catalyse a transition towards more sustainable global food systems.

... In their evaluation of the sustainability of the coffee sector, Earth Security Group (2017) identifies the need for "regenerative production systems which are commercially viable, " although they do not mention food security or income diversification. Improved yields/ha, for example, a doubling of national yield averages, may benefit efficient growers, but would lead to general overall overproduction putting downward pressure on coffee prices (Waarts et al., 2019). Well-designed multi-strata agroforestry appears to offer a way forward based on well-yielding coffee with lower costs of production based on nutrient recycling and nitrogen enrichment, pest and disease suppression based on biotic and abiotic factors and labor efficiencies in harvesting and other practices. ...
... The potential of coffee with agroforestry to contribute to living and prosperous incomes needs to be dimensioned by farm size, availability of markets and off-farm services and natural resource base. Waarts et al. (2019) highlight the challenges for different sub-groups of farms based on income and land size to improve livelihoods through commodity production and the vulnerabilities of very smallholders and workers. The importance of data-driven analysis is key to more effective research and policy agendas. ...

Sixty percent of global coffee is produced from farms of <5 ha. Studies show that returns from such farms do not generate a living income for producers or workers threatening supplies. Smallholders use agroforestry to reduce coffee production costs, diversify income and address livelihood needs. We undertook a three-phase analysis to test the following hypothesis. Current coffee agroforestry must shift from a low labor, low risk-stable return, slowly-changing matrix to more active management of species and stem turnover in system renovation cycles targeted to sustaining, reorienting and intensifying ecosystem-based benefits to coffee production, diversified income and household food. First, we conducted a document survey of current traditional tree diversity, research trends, and market drivers for more benefits-oriented agroforestry. Second, we proposed a framework for multiple benefits quantification converting tree use characteristics and density into five categories of benefits, each with sub-categories which we tested using previously collected data of stem density by species from coffee agroforestry in northern Nicaragua. Third, we modeled radiation in mixed canopy scenarios using the program SExI-FS based on modifications of species and density to target food and income diversification and tested our framework by quantifying benefits. We found that smallholder coffee faces farms decreasing coffee margins, labor scarcity, new pests and climate variability best addressed with targeted and adaptive shifts in coffee varieties and associated trees. Increasing data demands from certification and regulations provide a basis more data-driven coffee farm management. Our data bases of stem density by species of established agroforestry systems were sufficient to identify gaps in food and income benefits which were addressed in the scenarios thereby verifying the hypothesis. The benefits ranking both of current systems and three scenarios also provided insights into data collection specifications for a more rigorous academic test of the hypothesis and data-driven grower strategies for agroforestry transformation.
... It is a major source of revenue and a key contributor to the socioeconomic infrastructure in Ghana. The commodity directly employs about 800,000 farmers in Ghana, and a large proportion of their income (about 80%) comes from cocoa production [1]. Similarly, in Cote d'Ivoire, cocoa employs approximately 1,000,000 farmers and constitutes about 90% of their income [1]. ...

Cocoa production is one of the leading causes of deforestation in West Africa. Agroforestry cocoa systems are increasingly promoted as a possible solution to deforestation. This study seeks to understand the trade-offs within agroforestry cocoa in full-sun and high-tech plantation cocoa systems in Ghana. It uses secondary data collected from an extensive literature search. The results established various trade-offs between cocoa yields and other provisioning services derived from the agroforestry services. While the cocoa yields in high-tech systems are almost thrice those in agroforestry systems, the total value of all the provisioning services is highest within the shaded systems. The economic value of per hectarage yield is estimated at USD 8140, USD 5320 and USD 5050 for shaded, full-sun and high-tech systems, respectively. Agroforestry systems also have higher ecosystem services compared to full-sun cocoa and high-tech cocoa systems. The high pesticide use in Ghana′s high-tech cocoa systems is also strongly linked to water and soil pollution, as well as adverse effects on human health. The study concludes that different cocoa production systems in Ghana yield different types of ecosystem provision and are associated with externalities such as the effect of pesticides on soils, water and human health, thus there is a need for the careful consideration of the system from policy and practice perspectives.

... Cocoa production has been associated with deforestation, and therefore loss of ecosystem services, such as carbon sequestration and soil fertility (Akrofi-Atitianti et al., 2018;Tondoh et al., 2015) as well as biodiversity (Asigbaase et al., 2019;Bennett et al., 2021). Cacao is a major income source (output) in cocoa-producing areas, yet more than 30% of the farmers in the two major cocoa producing countries, Cote d'Ivoire and Ghana, live below the $1.90 poverty line and more than 70% have incomes per capita below living income standards Waarts et al., 2019). This income poverty is associated with differences in multidimensional wellbeing between social groups (outcome), mediated by local governance, tenure arrangements and gender norms Hirons, Robinson, et al., 2018;Knößlsdorfer et al., 2021). ...

While international trade in agricultural commodities can spur economic development especially where governance is strong, there are also concerns about the local impacts of commodity production and their distribution. Previous frameworks have primarily focused on trade effects on environmental conditions in production regions, as well as economic growth and food security. Instead, we develop a conceptual framework for understanding the impact of agricultural trade on multidimensional wellbeing and equity. The purpose of the framework is to guide the analysis of the impacts of trade on people, by identifying the core concepts and organising the complexity of the local social impacts of global value chains. The framework is supported by evidence from studies on trade in soy, coffee, cocoa, and palm oil.
Article
While international trade in agricultural commodities can spur economic development especially where governance is strong, there are also concerns about the local impacts of commodity production and their distribution on the environment and on people. The sustainable development goals (SDGs), though seeing trade as a means to support their achievement, recognise the need to address potential negative social and environmental impacts. It is therefore important to assess the contribution of international trade to the SDGs in commodity production areas. The environmental impacts of commodity production are widely acknowledged, but much less is known about its social impacts, and how this affects poverty reduction objectives across different dimensions. Impacts on human wellbeing and equity depend on a multitude of factors, including resources, systemic conditions and outputs of production. Through a broad literature review on soy, coffee, cocoa and palm oil, we show how studies have addressed different aspects of these factors and their impacts. The paper demonstrates how efforts by actors in global supply chains are related to a large number of SDGs and their targets. We link the social impacts and factors to the SDGs and a list of potential indicators and variables to guide operationalisation of assessments in new empirical studies.

This Campbell systematic review examines the effects of input subsidies on agricultural productivity, beneficiary incomes and welfare, consumer welfare and wider economic growth. The review summarizes evidence from 15 experimental and quasi‐experimental studies and 16 studies that use computable models, the majority concerning sub‐Saharan Africa. This review examines studies that evaluate the impact of agricultural input subsidies, including subsidies for agricultural machinery, seeds or fertilisers, on farmers, farm households, wage labourers or food consumers in low‐ or lower‐ middle‐income countries. It includes 15 experimental and quasi‐experimental studies and 16 simulation modelling studies. The majority relate to sub‐Saharan Africa (15 to Malawi) and to subsidised fertilizers and seeds. Fertiliser and seed subsidies are associated with increased use of these inputs, higher agricultural yields and increased income among farm households, but evidence of their effects on poverty is limited. There is much evidence that subsidy schemes are prone to inefficiency, bias and corruption. Models show that introducing or increasing subsidies generally results in positive effects for consumers and wider economic growth. However, the models indicate that the way subsidies are funded, world input prices and beneficiary targeting all have important influences on predicted outcomes. The authors were not able to find any studies examining subsidies for machinery. Plain language summary Agricultural input subsidies raise input use, yields and farm income. The review in brief Agricultural input subsidies raise input use, yields and farm income, but the evidence base is small and comes from a limited number of schemes and countries. What is this review about? Greater use of improved seeds and inorganic fertilisers, and increased mechanisation, could boost agricultural productivity in some low‐ or lower‐middle‐income countries, but there is disagreement about whether subsidising these inputs is an effective way to stimulate their use. This review examines the evidence for impacts of input subsidies on agricultural productivity, beneficiary incomes and welfare, consumer welfare and wider economic growth. What is the aim of this review? This Campbell systematic review examines the effects of input subsidies on agricultural productivity, beneficiary incomes and welfare, consumer welfare and wider economic growth. The review summarizes evidence from 15 experimental and quasi‐experimental studies and 16 studies that use computable models, the majority concerning sub‐Saharan Africa. What are the main findings of this review? What studies are included? This review examines studies that evaluate the impact of agricultural input subsidies, including subsidies for agricultural machinery, seeds or fertilisers, on farmers, farm households, wage labourers or food consumers in low‐ or lower‐ middle‐income countries. It includes 15 experimental and quasi‐experimental studies and 16 simulation modelling studies. The majority relate to sub‐Saharan Africa (15 to Malawi) and to subsidised fertilizers and seeds. What are the main results of this review? Fertiliser and seed subsidies are associated with increased use of these inputs, higher agricultural yields and increased income among farm households, but evidence of their effects on poverty is limited. There is much evidence that subsidy schemes are prone to inefficiency, bias and corruption. Models show that introducing or increasing subsidies generally results in positive effects for consumers and wider economic growth. However, the models indicate that the way subsidies are funded, world input prices and beneficiary targeting all have important influences on predicted outcomes. The authors were not able to find any studies examining subsidies for machinery. What do the findings of this review mean? Input subsidies can increase input use, and raise agricultural productivity with wider benefits. However, the design of subsidy schemes is crucial to their effectiveness, if they are to reach the desired farmers and stimulate input use. The effectiveness of subsidies in comparison to other interventions requires further study. A relatively small number of appropriate studies were found, and well‐documented research in countries beyond sub‐Saharan Africa is needed to ensure the wider relevance of these results. Mixed‐methods, theory‐based impact evaluations would help explore the impacts of different levels of subsidies for different beneficiaries. Simulation models studies could make more use of rigorous evidence from experimental and quasi‐experimental studies and examine more helpful subsidy comparisons. More clarity is needed in the reporting of methodological approaches, statistical information and the type and size of input subsidy implemented or modelled. How up‐to‐date is this review? The review authors searched for studies up to 2013. This Campbell systematic review was published in 2018. Executive summary/Abstract Background In recent decades, agricultural productivity in low‐ and lower‐middle‐income countries, particularly in Africa, has fallen increasingly behind that of upper middle‐income countries. Adequate use of agricultural inputs such as improved seeds and inorganic fertilisers has been identified as one way of enhancing agricultural productivity. However, these inputs can be financially unaffordable or unattractive to many poor farmers in developing countries. Agricultural input subsidies aim to make inputs available to users at below market costs as a way of incentivising adoption, increasing agricultural productivity and profitability, increasing food availability and access and ultimately reducing poverty and stimulating economic growth. They were common in poor rural economies in the 1960s and 70s. Their use declined in the 1980s and 90s, but recent years have witnessed a resurgence of interest and investment, mainly in Africa. There remains considerable debate about the effectiveness and efficiency of their use and the conditions under which they may or may not work. Objectives This systematic review explores the effects of agricultural input subsidies on agricultural productivity, farm incomes, consumer welfare and wider growth in low‐ and lower‐middle‐income countries. This research question is divided into the following primary and secondary research questions: • 1. What are the effects of agricultural input subsidies on agricultural productivity and beneficiary incomes and welfare? • 2. What are the effects of agricultural input subsidies on consumer welfare and wider economic growth? Search methods We carried out a systematic search for includable studies in a wide range of sources and using a variety of search methods. We searched academic and online databases, carried out forwards and backwards citation tracking of included studies, and consulted experts. There were no restrictions on publication year, type or language, though searches were undertaken in English. The main searches were completed in November 2013. However, we incorporated additional papers after this date where they became available before our analysis was completed. Selection criteria To be included, studies had to examine the effects of agricultural input subsidies, including products, machinery, seeds or fertilisers, on farmers, farm households, wage labourers or food consumers in low‐ or lower‐ middle‐income countries. Eligible comparisons included no active agricultural input subsidy intervention, wait‐list, alternate input subsidy intervention, or other interventions providing access to inputs. We included experimental or quasi‐experimental studies to address our primary research question regarding primary outcomes of adoption, productivity and farm income. We included econometric modelling studies to address our secondary research question on consumer welfare and wider economic growth outcomes. Studies were assessed by a single reviewer at both title and abstract level and full‐text level. A second reviewer then checked screening decisions taken at full‐text level. Data collection and analysis We extracted a range of data including bibliographic details, outcomes, time period covered, study design and outcomes data. For our primary research questions we synthesised evidence from experimental and quasi‐experimental studies using meta‐analysis, meta‐regression analysis and a qualitative synthesis of relevant implementation and contextual factors. For our secondary research questions we synthesised evidence from modelling studies narratively and displayed effects in scatter plots where possible. Results We identified 15 experimental and quasi‐experimental studies that assess the effectiveness of agricultural input subsidies on adoption, yield and farm incomes. We also identified 16 studies that use computable models that simulate the effect of agricultural input subsidies on measures of consumer welfare and wider growth. Overall, the evidence base is limited with a disproportionate focus on subsidy programmes in sub‐Saharan Africa and in particular on the case of Malawi. Most studies also have a focus on fertilisers and/or seeds rather than other types of inputs. We undertook meta‐analysis of experimental and quasi‐experimental studies to examine the effect of agricultural input subsidies on adoption, productivity, household income and poverty. The findings for primary outcomes are as follows: • Adoption: Meta‐analysis of seven experimental and quasi‐experimental studies indicates an increase in adoption by 0.23 standard deviations (SD) (95% confidence interval (CI) [0.08, 0.38]) for farmers receiving agricultural input subsidies versus those not receiving agricultural input subsidies. • Productivity: Across five studies, which were able to account adequate for confounding, there is an increase in yields of 0.11 SD (95% CI [0.05, 0.18]) for agricultural input subsidy recipients, compared to non‐recipients. • Farm income: Recipient farmer income, measured by household expenditure and income and crop income and revenue from four studies, increases by 0.17 standard deviations (SD) (95% CI [0.10, 0.25]), over that of non‐recipients. • Poverty: Only two studies report the effects of agricultural input subsidies on poverty, making it difficult to draw any clear conclusion. Meta‐regression found no association (positive or negative) between subsidy size and agricultural outcomes. However, narrative synthesis of data relating to programme implementation, input subsidy delivery mechanisms, farmer take‐up and usage of inputs, leakage of vouchers or inputs, and other associated factors indicates several points at which the theory of change for input subsidies breaks down. Subsidy vouchers do not always reach farmers in the quantities intended. Furthermore, where they do reach farmers they are not always used, and as a result providing subsidised inputs may not necessarily increase the amount of inputs used by farmers in absolute terms. We also synthesised data from simulation modelling studies of consumer welfare‐ and economic growth‐related outcomes including staple food prices and consumption, labour demand and agricultural wages, poverty incidence and gross domestic product (GDP). Results suggest that the relationships between the size of the change in subsidy and the outcomes of interest to be in line with our theory of change. However, analysis of modelling studies also indicates that factors such as how subsidies are funded, world input prices and beneficiary targeting can all play important roles in determining the effectiveness of input subsidies and their relative value compared to alternative policy options for agricultural development and poverty alleviation. Authors' conclusions Implications for research Overall, this review finds generally positive results for both primary and secondary outcomes across our theory of change. Included studies provide evidence linking fertiliser and seed subsidies to increased use of the subsidised inputs, higher agricultural yields and increased income among farm households, while the limited evidence relating to effects on poverty make it difficult to draw any clear conclusion. Models simulating subsidy effects show the introduction or increase in subsidies generally results in positive effects for consumers and wider economic growth. However, the review also indicates the importance of programme implementation and wider contextual factors. A narrative synthesis of data from experimental and quasi‐experimental studies finds implementation problems, with inputs not always made available or used as planned. Modelling studies indicate that the positive effects of subsidies are sensitive to changes in contextual factors endogenous and exogenous to the subsidy itself. There are also a number of implications for research. The review finds a relatively small evidence base of both experimental and quasi‐experimental studies, and econometric modelling studies. The evidence base focuses on a limited number of countries and evidence from a wider set of contexts where subsidies are used would be welcome. Implications for policy and practice Mixed‐methods, theory‐based impact evaluations can explore different levels of subsidies and unpack outcomes and assumptions along the causal chain, for different sub‐groups of beneficiaries. Simulation models studies should make more use of rigorous evidence from experimental and quasi‐experimental studies in determining coefficients used for household behaviour and the micro‐economic effects of subsidies. Furthermore, including multiple simulations in modelling studies to offer a range of different possible scenarios may be of more use to policy makers rather than simple ‘with or without subsidy’ comparisons. Researchers should ensure that they more clearly report methodological approaches, relevant statistical information and the type and size of input subsidy implemented or modelled.

Crop diversification is one of the most cost‐effective way of reducing uncertainties in farmer's income, especially among poor smallholder farmers. However, poverty is a complex concept, which includes more dimensions than only income. This review investigates the contribution of crop diversification to Sustainable Development Goal 1(SDG1) “No poverty” by also considering other dimensions of poverty, namely gender equality, food security and nutrition, and vulnerability to climate change. It demonstrates that the contribution of crop diversification to food security and nutrition, gender equality, and reduction of poor farmers' vulnerability to climate change has not been properly researched. Several factors across the studies analysed were found to influence the implementation of crop diversification, but these were hardly connected to poverty reduction. New research and policy impact evaluation methods that follow a sustainability approach perspective to poverty need to be undertaken in order to assess the contribution of crop diversification to SDG1.

Zero-deforestation commitments are a type of voluntary sustainability initiative that companies adopt to signal their intention to reduce or eliminate deforestation associated with commodities that they produce, trade, and/or sell. Because each company defines its own zero-deforestation commitment goals and implementation mechanisms, commitment content varies widely. This creates challenges for the assessment of commitment implementation or effectiveness. Here, we develop criteria to assess the potential effectiveness of zero-deforestation commitments at reducing deforestation within a company supply chain, regionally, and globally. We apply these criteria to evaluate 52 zero-deforestation commitments made by companies identified by Forest 500 as having high deforestation risk. While our assessment indicates that existing commitments converge with several criteria for effectiveness, they fall short in a few key ways. First, they cover just a small share of the global market for deforestation-risk commodities, which means that their global impact is likely to be small. Second, biome-wide implementation is only achieved in the Brazilian Amazon. Outside this region, implementation occurs mainly through certification programs, which are not adopted by all producers and lack third-party near-real time deforestation monitoring. Additionally, around half of all commitments include zero-net deforestation targets and future implementation deadlines, both of which are design elements that may reduce effectiveness. Zero-net targets allow promises of future reforestation to compensate for current forest loss, while future implementation deadlines allow for preemptive clearing. To increase the likelihood that commitments will lead to reduced deforestation across all scales, more companies should adopt zero-gross deforestation targets with immediate implementation deadlines and clear sanction-based implementation mechanisms in biomes with high risk of forest to commodity conversion.

Voluntary commitments to eliminate or reduce deforestation are developing into a powerful framing of global activities to combat deforestation and forest degradation. With the demand for agricultural commodities expected to double in coming decades, pressure on forests is likely to increase, particularly in the Global South. This background study provides an overview of the governance landscape around zero deforestation pledges, to aid a better understanding of its workings and dynamics.

Mapping global deforestation patterns Forest loss is being driven by various factors, including commodity production, forestry, agriculture, wildfire, and urbanization. Curtis et al. used high-resolution Google Earth imagery to map and classify global forest loss since 2001. Just over a quarter of global forest loss is due to deforestation through permanent land use change for the production of commodities, including beef, soy, palm oil, and wood fiber. Despite regional differences and efforts by governments, conservationists, and corporations to stem the losses, the overall rate of commodity-driven deforestation has not declined since 2001.
