Abstract
The trade in soybean, an important animal feed product, exemplifies the environmental and
socio-economic impact of global markets and global agricultural policy. This paper analyses
the impact of increasing production of soybean in the exporting countries (deforestation and
grassland conversion) as well as in importing regions (decrease in permanent grassland by
substitution of grass as feed). Ecosystem services monetary values were used to calculate
the environmental and socio-economic impact of observed land use changes. This is bal-
anced against the economic value of the global soybean trade. The results prove that con-
sumption choices in one region have real effects on the supply of ecosystem services at a
large spatial scale. Conclusively, solutions to make this global market more sustainable are
discussed.
Introduction
Population growth and increasing consumption has led to a global increase in food demand
while fertile agricultural land is becoming scarcer [1–3]. Globalisation of food commodities is
taking place at a large scale, disconnecting production and consumption. High income coun-
tries ‘use’land abroad to ‘virtually’increase their agricultural land, also referred to as ‘virtual
land use’or ‘displaced land use’[1,3]. As a consequence, land and water resources needed for
food production are displaced, virtually transferring the environmental impacts to the produc-
ing countries [4]. International trade especially has led to large-scale land degradation and
deforestation causing a severe loss of natural resources and ecosystem services [5]. The negative
environmental impacts are unintended side-effects (i.e. environmental externalities) of farming
activities, and basically coming at the cost of the society [6]. Despite being an important cause
for market failure [7], externalities are little or not touched upon at the decision-making level.
However, there is a need for environmental costs to be factored into the evaluation of different

policy measures [8]. Indeed, the lack of information about the value of non-market ecosystem
services is still a major knowledge gap hampering informed ecosystem management [9]. The
concept of ecosystem services offers tools to identify, quantify and value some of those environ-
mental effects by explicitly linking ecological functioning with human wellbeing. The valuation
of environmental externalities aims to raise awareness on the negative and non-visible effects
of human activities and to provide information for decision makers [6]. Valuation techniques
are already used to quantify and monetise the impact of deforestation (e.g. Schmitz et al. [10]),
but no direct links have been made to international trade causing the deforestation and the
related costs on the produced goods. In this study, land use changes due to global soybean
trade both in exporting and importing countries are calculated and the associated environmen-
tal and socio-economic impact estimated using an ecosystem services valuation approach.
Materials and Methods
Case study: global soybean market
Soybean production is one of the worlds’booming industries with an increase of 200 million
tons in the global consumption since the seventies [11]. The success of the soybean lies within
its multiple applications: soybeans can be used in food products (e.g. tofu, soybean sauce), as
edible vegetable oil, biofuel and most importantly its meal can be used as protein source in live-
stock feeds. This paper studies the impact of the European soybean import, because it is world-
wide one of the most important importing regions and showing a strong increase in the last 50
years (Fig 1A). In particular the import from Brazil and Argentina is studied, because both
countries became the largest region of origin for soybean imported by Europe (Fig 1A) and
show a large increase in soybean area over the last decades (Fig 1B). In addition, it is especially
in South America that the “soybean boom”has generated well-studied impacts such as land
grabbing practices and deforestation, posing a severe threat to rainforest preservation [11–14].
The main threatened ecosystems in the exporting countries are rainforests (the Amazonian
and the Atlantic forest), and grasslands of the Pampa, the Campos and the Cerrado [15,16].
However, the effect of deforestation is mostly indirect. The main direct driver for deforestation
is cattle ranching; roughly 80% of recently deforested land in Brazil is used for ranching [17].
The expansion of soybean cultivation land happens mainly in pastures, displacing cattle ranch-
ing to forest areas and the savannah [18,19]. In more recent years, soybean cultivation also
moved to previously uncultivated ecosystems which lead to direct deforestation [17]. Hence,
the surge in soybean cultivation in Brazil and Argentina is partially at the cost of other arable
crops and grasslands but also linked to the loss of forest and savannah [18,20,21].
Soybean area expansion in Brazil and Argentina for the export to EU-27, 1961–2008.
The soybean virtual land in Brazil and Argentina for the EU market is calculated based on
annual soybean export to Europe (ton/y) and soybean yield per year in Brazil and Argentina
(ton/ha). To calculate the total soybean export volumes (soybeans and cake of soybeans), data
on cake of soybeans [21] is converted to the equivalent weight of beans (1 kg cake = 1.21 kg
beans,[19]). The soybean export to EU prior to 1986 (1961–1985) is missing and therefore cal-
culated by multiplying the soybean area (data since 1961) with the average share of the total
soybean production exported to EU between 1986 and 2008 (44% in Brazil and 45% in Argen-
tina). The soybean yield in Brazil and Argentina increased substantially over time from about 1
ton/ha in 1961 to 2.8 ton/ha in 2008 [21].
Associated land use changes in Brazil, Argentina and EU-27. The impact of soybean
expansion on deforestation and grassland conversion is estimated based on data retrieved from
governmental sources (e.g. www.embrapa.br), international literature on deforestation and
grassland conversion in general and due to soybean expansion in particular. For certain years,

sources indicate at the cost of which ecosystems soybean expansion is taking place (Table 1).
For the other years, the distribution of soybean area expansion in the different regions was esti-
mated assuming a linear trend. The area of deforestation and grassland conversion is calculated
by multiplying the soybean area for the export to Europe in each year with the relative distribu-
tion in the different regions. The area of deforestation is the sum of losses in Atlantic forest,
Amazon rain forest, half of the Cerrado [22] and Yungas forest, and grassland conversion is
the sum of Campos, Pampas, half of the Cerrado, Pampas and Gran Chaco.
Increasing soybean import by European countries is changing land use in Europe too [30].
The meat consumption and livestock sector in Europe shifted to less cattle and sheep and more
pigs and poultry [21]. One of the reasons is that pigs and poultry meat is cheaper because less
land use is needed to feed the animals combined with cheap protein-rich feed products [31].
For cattle production itself, a shift towards less grazing and more alternative feed like cereals
and protein-rich products is observed [32]. Protein-rich products consumed in Europe are

imported for 75%, of which 83% consists of soybean, from which again 60% comes from Brazil
and Argentina [21,31]. The increasing soybean import to Europe from both countries clearly
exemplifies the increasing consumption of protein-rich products by pigs, poultry and cattle.
Therefore, it is expected that the increasing soybean import resulted in a decrease of permanent
meadows and pastures and an increase of maize and other cereal production for animal feed.
Data on permanent meadows and pastures, cereal production, cattle stock, pigs stock and poul-
try stock between 1961 and 2008 was retrieved from FAO [21]. Correlations between soybean
import and changes in meat stock and between permanent meadows and cereal production
and meat stock changes are explored to corroborate these land use impact in Europe due to
increasing soybean import.
Environmental and socio-economic impact. A monetary value of ecosystem services per
land use was estimated based on a literature review of monetary values of food provisioning
and other ES for the different land use types in our study ($/ha/y). Economic values of ecosys-
tem services for the main ecosystems are based on the meta-review by Costanza et al. [33]. In
addition, values for the specific ecosystems in our study (e.g. Amazon forest) were added to
improve the relevance of the estimates for this case study (S1 File). The total economic value
(TEV) per land use, calculated as the sum of food provisioning and other ecosystem services,
was then multiplied with the land use changes to calculate the total annual impact ($/y). This
annual impact also includes the losses of the previous years because services from converted
land are lost forever (until restored). The calculated impact is a conservative estimate since
missing values for several services were not included in the total value. All data is compounded
to US$2008 values by using the Historical Consumer Price Index (U.S. Department Of Labor
Bureau of Labor Statistics). Data in Euro are converted to US$ with a factor 1 US$ = 0.7 €
(2008).
Results
Land use changes in Brazil and Argentina for the soybean export to EU-
27
In 1961, the soybean area needed in Brazil and Argentina for the EU export was about 0.1 mil-
lion ha and almost completely located in Brazil (99%). In 2008, the soybean area in both coun-
tries required for the EU export, increased to 11.8 million ha of which still the majority (53%)
located in Brazil (Fig 2A). This explosive expansion of soybean area happened mainly within
tropical grassland and savannah (2.2 million ha in Brazil and 4.5 million ha in Argentina) and
tropical forest (4 million ha in Brazil; 1 million ha in Argentina) (Fig 2B and 2C).
Associated land use changes in EU-27
Land use changes due to soybean import in the EU concern permanent meadows and pastures
and maize and other cereals. From 1961 to 2008, the European agricultural area of permanent
meadows and pastures decreased by 7 million ha (9%) from 76.3 to 69.3 million ha (FAOSTAT
—Resources—Resources—Land). This decrease is again a conservative estimate since the areas
of some countries (Croatia, Czech Republic, Estonia, Latvia, Lithuania, Slovakia and Slovenia)
are not included in the statistics between 1961 and 1992. With 85% of the imported soybean
coming from Brazil and Argentina (data 2008), about 6 million ha loss in permanent meadows
and pastures could be attributed to the EU soybean import from Brazil and Argentina. This
link between increasing soybean import and grassland losses in Europe is corroborated by cor-
relations between the livestock sector, soybean import and land uses in Europe. Although alter-
native feed is increasingly used in the cattle sector, the cattle stock is negatively correlated with

the soybean import since 1987 (correlation coefficient -0.97; Fig 3). Furthermore, the poultry
stock is positively correlated with the soybean import since 1987 (0.69; Fig 3). Unexpectedly,
the pigs stock is negatively correlated with the soybean import since 1987 (-0.75; Fig 3). This
could be explained by a small decrease in the pigs stock in the last 20 years (- 6%), but between
1961 and 1987 the pigs stock in Europe almost doubled. The decrease in cattle stock [21] but
also the reduction of grazing land used per cattle unit, could be linked to the decrease of mead-
ows and pastures in Europe with 6 million ha [34] (0.86; Fig 4). The shift in the livestock sector
causes an increasing demand for cereals and protein-rich products. However, no increase in
cereal production was found in the European data (instead a negative correlation was found
with the pig and poultry stock at the European scale of −0.83 and −0.86 respectively; Fig 4).
This could be explained by potential import of cereals. Conclusively, soybean import very
probably affects land use and land cover in Europe. Off course, the decline in pastures and ara-
ble land is also caused by other broad European land-use changes like urbanisation [35].

Economic valuation of the land use changes using ecosystem services
valuation
Tropical forests and tropical grasslands have the largest average social benefits when compar-
ing the involved land uses but the range in the monetary value is large (Fig 5). The environ-
mental and socio-economic impact of land use changes since 1961 in EU, Brazil and Argentina
due to the soybean trade, has reached an average net loss of 120 billion $/y in 2008 (Fig 6). This
is mainly the consequence of losses in ecosystem services from deforestation and converted
tropical grassland and savannahs in Brazil and Argentina, and to a small extent also the con-
verted grasslands in Europe. The conservative estimate of the total cumulated loss of natural
capital by EU-soybean trade between 1961 and 2008 amounts to 1.7 trillion dollars.
Discussion
Global soybean trade generates clear short-term benefits. The Brazilian and Argentinian
farming sector earns about 2.3 billion $/y from the soybean export to Europe (11.7 million ha
in 2008 (our calculation) and a net value of soybean area of 200 $/ha/y ([27])). For Europe,
the cost for soybean import from Brazil and Argentina is about 10 billion $/y (34 million ton

in 2008 and a market price for soybean meal in 2008 of about 300 $/metric ton (www.
indexmundi.com/commodities)). The benefit for Europe could be represented by the value of
the European livestock sector fed with soybean; 145 billion $ in 2008. This is the total value of
the EU-27 livestock sector in 2008 (152 billion €, or 220 billion $ (conversion rate 2008),
www.eufetec.eu) multiplied with the share of the livestock sector fed with soybean meal: 68%,
in protein equivalent ([36]). However, when considering the environmental consequences
with effects on a global and long term scale our results demonstrate that soybean import
might not be beneficial at all. For 2008, an environmental loss of 120 billion $ was calculated
(Fig 6). This confirms that agro-industrial benefits are often gained at the cost of the environ-
ment and future generations [10,31].
Soybean export data [21] point out that the virtual land in Brazil and Argentina needed to
meet the European soybean import had risen to 11.7 million hectares in 2008. This is compara-
ble to the 11.4 ha of virtual land for the soybean imports from Brazil and Argentina in the EU
according to Von Witzke and Noleppa [37] (i.e. 60% of their total of 19 million ha imported by
the EU). Soybean imports are a considerable part of the total virtual import of cropland by
Europe from Brazil and Argentina (about 40% of 51 million ha, [3]).
The impact of soybean area expansion on deforestation is mostly indirect. The main direct
driver for deforestation is cattle ranching; roughly 80% of recently deforested land in Brazil is

used for ranching. The expansion of soybean cultivation land happens mainly in pastures, dis-
placing cattle ranching to other forest areas and the savannah [18,19]. In more recent years,
soybean cultivation also moved to previously uncultivated ecosystems which lead to direct
deforestation. Hence, the increase in soybean cultivation in Brazil and Argentina is partially at
the cost of other arable crops and grasslands but could also be linked directly and indirectly to
forest and savannah conversion [18]. Our estimation of land use changes is based on available
information on deforestation and grassland conversion due to soybean expansion.
The impact of soybean import in Europe is situated in the livestock sector and associated
land uses (pastures and cereal production for animal feed), but also the more broader environ-
ment (e.g. nitrogen is imported with soybeans, [19]). The cattle stock and permanent meadows
and pastures are both decreased. The growth in the pig and poultry sector that depends on
cereals and protein-rich products as feed, together with a shift in the cattle sector to more alter-
native feed like cereals and protein-rich products [32], has not led to the expected increase in
cereal production in Europe. Instead, the total area for cereal production decreased (Fig 4).
This corresponds to the general trend in Europe of increasing urbanisation at the cost of agri-
cultural land [35]. The strong correlation between the cattle stock and pastures can be
explained by the strong location specific character, which is absent for the production of cereals
and protein-rich products. Cereals are traded within Europe and globally. Furthermore, the
European agricultural policy had over a long period a strong control on what is and what is not
produced in the European Union by the use of specific subsidies and production quota. Last
but not least, international agreements have enabled the cheap import of, for example,
soybean.
The economic approach is applied to make a full resource valuation and full cost pricing of
resources [8]. It is argued that there is a need to incorporate environmental costs in manage-
ment and policy debates. The economic valuation of ecosystem services is an approach to take
into account effects of human activities that are otherwise not accounted for (e.g. pollution,
waste). This enables a more integrated debate and inclusion of regions and generations that are
not involved in these discussions. However, it is important to note that the monetary values
have to be interpreted as a conservative and crude estimate and not as a total or exact value.
The primary function of the monetary outcome is to inform decision makers and non-govern-
mental organisations about the relevance of environmental effects and its societal implications
(e.g. contamination of air and water, reduced productivity, etc., [38]).
When translating the environmental effects into monetary values it becomes possible to
trade-off advantages (food) and disadvantages of global soybean trade (e.g. loss of wood and
non-wood materials, loss of water regulation, loss of climate regulation, and loss of opportuni-
ties for recreation and tourism). An optimal conversion rate to agriculture is at the maximum
of the net societal benefit, i.e. agricultural income corrected for environmental damage of con-
verted land (Fig 7A). Such an approach could suggest that the EU-Brazil-Argentina soybean
trade is situated in the ‘positive for society’zone (Fig 7; 137.3 $ soybean income versus 120 $
environmental loss from deforestation and grassland conversion). However, it is impossible to
determine the exact position of the global soybean market in Fig 7 since constant habitat values
(independent of how much forest and grassland is converted to soybean area) were applied.
We argue that forest and grassland values were underestimated because of the actual and his-
toric large deforestation and grassland conversion rates in particular in Brazil and Argentina
[39,40]. When more forest and grassland has been converted already, the societal value of the
remaining area will increase because it becomes rare. Moreover, soybean income was overesti-
mated because of the large amounts of soybean that are being produced. When there is suffi-
cient food produced, the societal value of producing more will decrease. This reasoning leads to
Environmental and Socio-Economic Impact of the Soybean Market

the presumption that the actual position is more to the right side of the graph (Fig 7): the opti-
mum ‘conversion to soybean area’has likely been passed.
On the one hand, global food demand -and global soybean trade-, will keep increasing due
to population growth and increasing meat consumption globally, as will the marginal value of
soybean production expansion. This in turn can shift the optimum ‘conversion to soybean
area’to the right (Fig 7B). On the other hand, increasing meat consumption has negative health
consequences [31] leading to an additional societal cost and hence a shift to the left (Fig 7C).
This model shows the complex situation of trading off the importance of increasing food pro-
duction with environmental and societal costs.
Our results demonstrate the problematic implications of global food trade in case of soy-
beans. However, many options and policy measures are available or even in place to mitigate
those negative effects. Without pretending to solve this complex problem, we present a non-
exhaustive list of actions or partial solutions that could and should be considered to steer the
global soybean market in a more sustainable direction (Table 2). The actions are diverse: at
local or global scale, in the importing or exporting country or globally to work on the shared
responsibility, using legal, economic or social incentives, and from being preventive to
curative.
The proposed actions articulate with the market in three major ways. First, some actions
can reduce the demand for soybeans such as using alternatives for soybean feed (e.g. promote
grass fed meat instead of grain fed meat) and promote sustainable consumption (e.g. avoid
food waste in all steps of the food chain, and reduce meat consumption in general). Food waste
is a substantial problem; about 40% of all European food produced is not consumed. Recycling
of animal waste is banned at the end of the nineties as a consequence of the mad cow disease in
Europe, but new opportunities arise for example by using insects, fed on animal protein meals,
as animal feed [41]. This has the potential of both reducing food waste and soybean use. Fur-
thermore, the link between meat consumption and soybean use is strong; halving the meat con-
sumption in the European Union would reduce the use of soymeal by 75% [31]. Eating grass-
fed meat in Europe means the destruction of high valuable ecosystems and de-stabilising the

self-sufficiency of the soybean producing countries [42]. The European meat sector depends
heavily on the cheap soybean import and changes in this global market (e.g. when incorporat-
ing losses from deforestation) will have unforeseen effects. Fundamental changes in the Euro-
pean meat sector with a focus on more self-sufficiency could reduce the risk for food security
(both risk for sufficient import and export opportunities) and reduce the negative externalities
in the rest of the world. Fundamental changes in agricultural management towards more sus-
tainability, a better balance between supply and demand, and technical considerations such as
crop rotation will contribute to the conservation of local and global ecosystem services (food
provisioning, but also soil retention, groundwater quality, climate change, biodiversity etc.).
Secondly, some actions can reduce the environmental damage associated with soybean pro-
duction. Many subsidies are promoting destructive behavior. In Brazil, for example, infrastruc-
ture towards the Cerrado and the Amazon forest is organized to promote economic activities
which promote indirectly deforestation. All trends are going in the direction of increasing crop
area expansion and increasing environmental damage. Possibilities are: certificate system for
sustainable soybean (Round Table for Responsible Soy, www.responsiblesoy.org), import soy-
bean from various regions to spread the pressure, sustainable agricultural practices (e.g. agro-
forestry, avoid monoculture).
Thirdly, actions could be taken to compensate inevitable environmental damage with forest
conservation programs, compensation and payment schemes for environmental services. Eco-
nomic valuation enables to charge consumers with the cost of externalities and hence to make
‘polluting’goods less attractive (i.e. more expensive) [43]. Likewise, this valuation could also be
used to set penalties for destruction of ecosystems and biodiversity [5].

Our analysis shows that the European soybean import has deleterious ecological and socio-eco-
nomic effects, eroding natural capital by provoking permanent losses of important ecosystem
services, while providing no economic benefits to society at large. The ecosystem services con-
cept offers an approach to demonstrate real impacts on local communities (e.g. clean drinking
water polluted by fertilizers) and global/future communities (e.g. global climate regulation
decrease by deforestation). For this specific global trade market, quantification of these effects
in monetary values allowed discussion of the complex trade-offs involved in the expansion of a
global market. Finally, a set of actions to increase the protein self-sufficiency of Europe and
decrease negative externalities of global soybean trade are discussed.
