Abstract and Figures

This chapter presents the contribution of “chakra,” a traditional agroforestry system, to climate change adaptation and biodiversity conservation in Ecuador’s Amazonian communities. IPCC’s methodology was used for the estimation of carbon sequestration in soil, biomass, and cacao plantations. Carbon levels in multiple systems of land use were measured through temporary plots. Chakra is efficient to adapt to climate change due to higher levels of carbon sequestration and tree diversity in comparison to other forms of land use. Chakra allows for sustainable use of forests by combining cultivation of the Ecuadorian finest aromatic cacao, controlled timber extraction, production of staple food, and conservation of medicinal plants. Chakra enables Amazonian communities to contribute to both food security and well-being and conservation of the region’s high biodiversity. The chapter informs policy makers and communities about the importance of strengthening traditional agroforestry to achieve environmental and social sustainability. The Amazon region is a vulnerable ecosystem, where adaptation to climate change depends on the extent to which the options for land use are compatible with the conservation of biodiversity and the provision of the ecosystem services that sustain local communities’ livelihoods. The chapter provides solid evidence that this might be possible through traditional agroforestry.

Introduction
Traditional systems of agricultural production, particularly agroforestry, have been recognized
worldwide as an integrated approach to sustainable land use. More recently, agroforestry systems
are believed to have a high potential to contribute to climate change mitigation through carbon
sequestration. This has brought a renewed interest in research both on the biophysical conditions
under which efcient carbon sequestration can happen and the factors that can enable positive gains

for farmers. Yet, the evidence found in this recent literature is not conclusive and generalizations
tend to become unrealistic, often because several interrelated and site-specic factors inuence the
rate and extent to which agroforestry can sequester carbon (Noponen et al. 2013; Oelbermann
et al. 2004).
Agroforestry, generally referred as the practice of growing of trees and crops in interacting
combinations, is based on the premise that complex land-use systems result in greater efciency
of resource (nutrients, light, and water) capture and utilization and greater structural diversity that
enables tighter nutrient cycles, therefore, more system stability and resilience at site level and
connectivity between forests and other landscape features at landscape and watershed levels (Nair
et al. 2008). The advantage of agroforestry as a mechanism for climate change mitigation is that,
compared with other terrestrial options, agroforestry has other environmental benets such as
restoring and maintaining above-ground and below-ground biodiversity, corridors between
protected forests, and reduction of pressure on natural forests and maintaining watershed hydrology.
These ecological foundations of agroforestry systems have been associated with a potential for the
provision of ecosystem services worldwide and contribution to food security and poverty alleviation
in developing countries (c.f. Lal 2001; Pandey 2002).
In large-scale studies of regions where data is available and reliable, the potential of agroforestry
to increase carbon sequestration is promising. For example, in European agriculture it has been
estimated to reach near 35 % of all CO
2
-equivalent emissions in the EU in 2007, which at prices of
2012 would have a value of 282 euro/ha (Aertsens et al. 2013). Freibauer et al. (2004) analyzed the
potential for carbon sequestration and economic viability of agricultural soils in Europe (EU-15) and
concluded that efcient carbon sequestration in agricultural soils demands a permanent management
change and implementation concepts adjusted to local soil, climate, and management features. In
tropical agroforestry systems, Albrecht and Kandji (2003) estimated the carbon sequestration
potential in a range of 1.12.2 pc carbon in the terrestrial ecosystems over the next 50 years.
However, there are shortcomings of these estimates associated with the uncertainties related to future
shifts in global climate, land use, and land cover and the poor performance of trees and crops on
substandard soils and dry environments, pests, and diseases. Also, research in the Appalachian
agriculture (López-Bellido et al. 2010) shows that current practices do not allow for contribution to
C sequestration; hence, improved agricultural practices are needed in order to increase soil organic
carbon sequestration.
In developing countries, where reliable environmental and economic data are less available
c.f. (Claessens et al. 2012), there is increasing expectation about the economic impact of agricultural
carbon sequestration. In the Andean region, the fragile nature of agroecosystems and limited
capacity of resource-poor farmers to adopt the large-scale use of fertilizers and pesticides suggest
the need for agroecological intensication to restore soil functioning and ensure long-term sustain-
ability (Fonte et al. 2012). However, Antle et al. (2007) used a model to simulate the effects of
adopting agroforestry practices in the Peruvian Andes and showed that the economic potential is
relatively low at carbon prices below $50 per MgC. The price would need to rise signicantly
(100 %) to make the adoption of agroforestry in terraces attractive; if that happens, carbon
sequestration could raise per capita incomes by up to 15 % and reduce poverty by 9 %. In Central
America, Somarriba et al. (2013) suggest that, among the agroforestry crops that have the greater
potential to mitigate climate change, the cacao tree is credited for stocking signicant amounts of
carbon.
Research on sub-Saharan Africa, where climate change is predicted to have considerable negative
impacts, shows also that carbon sequestration in agricultural soil can make only modest contribu-
tions, in a range of 36 of fossil-fuel contributions, to mitigation of overall greenhouse gas emissions

(Hutchinson et al. 2007). Palmer and Silber (2012) showed that, in order to make the potential of
traditional land use effective for improving the farmersincome of Mozambique, systems that
combine sequestration and cash crop production have higher net benets, although they have less
carbon-sequestration potential. In West African Sahel as in sub-Saharan Africa, carbon sequestration
is a promising incentive for introducing agroforestry practices and contributing to sustainable land
use (Takimoto et al. 2008; Thangata and Hildebrand 2012); therefore, countries that incentive this
practice can benet from REDD+ and other global environmental policies for climate change
mitigation. Additionally, as it has been demonstrated in traditional societies like in many parts of
rural China (Xu et al 2007), the economic impact of environmental policies that promote carbon
sequestration through agroforestry can also have social implications in terms of participation,
increased mobility, and less subsistence agriculture-based livelihoods.
This brief review suggests that research is not conclusive and more is needed, especially for the
tropics, to more accurately capture the impact of region-specic interactions between climate, soil,
and management of resources on carbon sequestration, which are lost in global-level assessments. In
the recent global context of climate uncertainty, many productive ecosystems are endangered.
Diversied farming systems are an example of complex systems which are able to adapt and resist
the effects of climate change. These systems have a high structural complexity which enables them
to act as a buffer against temperature uctuations (Nicholls 2013) and, as Ríos et al. (2007) suggest,
there is increasing interest in understanding how local populations traditional practices can generate
a path for sustainable use of plant diversity and adaptation to climate change. The purpose of this
chapter is to present the contribution of chakra,a traditional agroforestry system developed in
Ecuadors Amazonian communities, to climate change adaptation and biodiversity conservation.
Given that the Amazon region is a vulnerable ecosystem, where adaptation to climate change
depends on the extent to which the options for land use are compatible with the conservation of
biodiversity and the provision of the ecosystem services that sustain local communitieslivelihoods,
we argue that the chakra system is efcient to adapt to climate change due to higher levels of carbon
sequestration in comparison to other forms of land use. Chakra also allows for sustainable use of
forests by combining cultivation of the Ecuadorian nest aromatic cacao, controlled timber extrac-
tion, production of staple food, and conservation of medicinal plants. The local governance system
established around chakra enables Amazonian communities to improve their chances for food
security, increasing income, and conservation of the regions high biodiversity. In the remaining
sections, we develop this argument, preceded by a description of the methodology used in the study
and a contextual description of the Ecuadorian Amazon.
Chakra in the Context of the Ecuadorian Amazon
Characteristics of the Ecuadorian Amazon
Ecuador represents only 0.2 % of the earths surface; it is positioned in the 6th place among the most
mega-diverse countries in the world (Mittermeier 1988), hosting around 10 % of the worlds plant
species (CAAM 1995). In this epicenter of biodiversity, the Andean-Amazonian space is considered
as a leading hotspot(Myers et al. 2000) with a great potential to provide the ecosystem services
needed to sustain local livelihoods and global goods such as carbon forest.
However, one of the major problems facing this area is deforestation mainly due to the increase of
the agricultural frontier (Pichón 1997; Bilsborrow 2004; Pan and Carr 2010). The forest clearing
started in the early 1960s, when the emergent oil industry induced the formation of human
settlements in the rainforest, and continued at a rapid pace during the land reform, from 1964 to

1973, when a process of agricultural colonization (Murphy et al. 1997; Sierra 2000; Mena
et al. 2006) changed signicantly the pattern of land use from forests to agricultural crops and
livestock grasslands (Carr and Bilsborrow 2001; Torres et al. 2005; Pan and Carr 2010). Farmers
from coastal and highland areas of Ecuador settled in the Amazon and introduced practices of
monoculture (Pichón 1997), unsuitable for the fragile Amazonian soils. The expansion of agricul-
ture and the introduction of livestock induced signicant levels of immigration and the construction
of road infrastructure, which severely impacted the Amazon ecosystems and landscape (Pichón
1997; Wunder 2000; Pan et al. 2005).
The challenges of biodiversity conservation and recovery of cultural patrimony associated with
traditional land use led to design a strategy based on spatial planning, supported by the UNESCO. As
part of this strategy, the Man and Biosphereprogram delimitated an area located in northeastern
Ecuador to be the Sumaco Biosphere Reserve (SBR), covering 931,930 ha, i.e., 8 % of the
Ecuadorian Amazon (MAE 2002). The core of this strategy is the conservation of the Sumaco
Napo-Galeras National Park in an area of 205751.11 ha (MAE 2013; see, Fig. 1).
The native Kichwa population inhabiting the Ecuadorian Amazon is concentrated in Napo
province, representing 60 % of Napos total population (Irvine 2000; INEC 2010). However,
since the 1980s, Napo has become one of the main attractive centers for migration (Arévalo
2009), particularly to the SBR, for its potential for economic activity. The new human settlements
have located in the SBR transition and buffer areas.
Traditional Agroforestry in the Ecuadorian Amazon: The Chakra System
Cultivation of small plots within the rainforest is a traditional practice that, over the centuries, the
Kichwa population from the Ecuadorian Amazon has developed in order to sustain their livelihoods.

Such a pattern of land use, locally known as chakra,integrates cultivation of staple food and
medicinal plants, including manioc (Manihot esculenta Crantz), banana (Musa paradisiaca L.),
peach palm (Bactris gasipaes Kunth), and other edible and medicinal plants that enable food and
health security (Irvine 2000; Lu et al. 2004; Whitten and Whitten 2008). Over time, other agricul-
tural species with commercial value have been integrated into this traditional agroforestry system,
which is the case of the ne-avored cacao (Theobroma cacao L.) and robusta coffee (Coffea
canephora Pierre ex A. Froehner). The size of cultivation plots of cacao within an Amazonian
chakra is in a range of 0.54 ha (Gizb 2011); these plots are generally located in remaining areas of
primary and secondary forests and fallow land. This forms a landscape that resembles a mosaic
economically productive and ecologically friendly to the biodiversity of the area.
The SBR contains near 12,500 ha of cacao cultivated in the chakra system, which are managed by
9,200 farmers, approximately (Gizb 2011). Most of it is located in buffer and transition areas of the
SBR and Yasuní, within the so-called cacao corridor (see, Fig. 1), and belongs to indigenous Kichwa
communities which, since the 1970s, had to adapt to the process of agricultural colonization and
relocated their settlements in areas surrounding the Sumaco and Yasuni reserves. While the state has
guaranteed the property rights of these communities through land titles and facilitated their access to
agricultural credit (Irvine 1989,2000; Perreault 2003), the intensive migration to the area observed
in the last 40 years (Bilsborrow et al. 2004) has also implied diversication of local population and
new forms of land use oriented not only to subsistence but also to the market. From an economic
perspective, the integration of subsistence and commercial agriculture specialized in the market
niche of ne cacao has implied the improvement of householdsincome. Ecologically, it has
produced the effect of redrawing the northern Amazon landscape, pictured now as
a multifunctional rainforest with productive plots of cacao or coffee, patches of primary and
secondary forest, and stubble and non-used areas, all of which are needed for the soilsresilience
in their multiple strata.
The cultural meaning of the chakra system for local population is directly related to the conser-
vation of the Amazon landscape. Cultural practices among the SBR and Yasuní reserve include:
selective classication of crops and identication of fertile or unfertile time periods based on the
moons phases, a particular local calendar, the uorescence of some trees, the birdsincubation
period or ight style, and/or some insectsbehavior (Avilés and Sarmiento 1997). As suggested by
Irvine (2000) and GIZ (2013), these practices have enabled indigenous local population to achieve
a certain harmony between food security, income generation, and the preservation of traditional
medicine and spiritual values.
Recently, new challenges that climate change presents to local population in the SBR have
motivated research both on the capacity of the chakra system to facilitate the adaptation of local
population and the rainforest ecosystems to climatic conditions and their capacity to contribute to
climate change mitigation. While the former goes beyond the scope of this chapter, the latter is
developed in detail in the following chapters.
Methodology
The research project Diversication of land use and carbon assessment for biodiversity preserva-
tion,in its initial phase, studies changes in carbon storage, biodiversity preservation, and produc-
tivity in various land-use systems. The investigation was implemented in 2011 in the buffer and
transition zone of the Sumaco Biosphere Reserve and aims at examining the potential for carbon
storage by the chakra system, therefore assessing their potential for climate change mitigation. The

project is located in the so-called cacao corridor in the province of Napo in the northeastern part of
the Ecuadorian Amazon region. The research was performed as results of an international collab-
oration of universities including the Amazon State University (Universidad Estatal Amazónica) in
Ecuador, the Tropical Agricultural Research and Higher Education Center (Centro Agronómico
Tropical de Investigación y Enseñanza) in Costa Rica, and the Technical University of Munich in
Germany.
The criteria used to select cultivation plots where traditional agroforestry practices are
implemented (i.e., classication of plots under the chakra system) were percentage of shadow
10 %, net area of chakras 0.5 ha, and the farmerswillingness to support the system. Fifteen
circular temporary plots of 1,600 m
2
under the chakra system were selected to measure the numbers
and diversity of tree species and the amount of carbon captured in each plot and to assess the
diversity of tree species and practices that produce food and medicinal plants. Similarly, 8 circular
temporary plots under the monoculture system were also selected for the purpose of comparison.
The cacao chakras included in the sample are, on average, 7 years old, have diversied shading
systems in multiple strata and growth periods, and have the potential to store carbon efciently each
year. Table 1summarizes the cultivation plotscharacteristics.
In all temporary plots of 1,600 m
2
, diameter at breast height (DBH) was measured (taken at
1.30 m) from all trees and palm with DBH 10 cm, and the total height was also measured. The
oristic diversity of species was identied in situ, by using common and scientic names at the level
of family, genus, and species. Species that were not recognized in situ were collected and identied
in a national herbarium with the help of expert botanists.
Multiple systems of land use were selected in the lower area of the Sumaco Biosphere Reserve
(Fig. 1), specically in Tena and Archidona cantons within the Napo province. All sites are located
below 700 m above sea level. The plots selected belong to farmers from the Kallari and Wiñak
producer organizations, both members of the Cacao Dialog Table (MCFA in Spanish) in the
SBR. Plots chosen for comparison in native forests were located in the Jatun Sacha Biological
Station (EBJS).
Research on the contribution of the chakra system to climate change mitigation adopted the IPCC
methodology for assessing the capacity of traditional agroforestry for carbon sequestration. This
includes methods to estimate the amount of biomass and carbon in each one of the land-use systems.
According to the methodology used by Jadán et al. (2012), ground biomass was estimated using
algometric equations formulated for primary rainforest species. These equations were also used to
calculate low-latizal sapling biomass and necromass (Table 2). The underground biomass was
calculated using the equation recommended by the IPCC (2003). The biomass of dead wood was
calculated based on volumes obtained via the Smalian formula taken in different decomposition
categories (Table 3).

The estimated biomass was converted into units of C by multiplying by the 0.5 factor of
conversion, as indicated in IPCC (2003). The values obtained were expressed as MgCha

(mega

The organic carbon in the soil was estimated using the percentage of organic C and the apparent

C to each of the components of the ecosystem (biomass, necromass, and soils) in each one of the
evaluated systems (Table 3).
The air biomass in tropical forests was estimated based on the wood density (d) of tree species

Contribution of the Chakra Agroforestry System to Climate Change
Mitigation
As reviewed in the Introduction, the benets of agroforestry systems for carbon sequestration and
climate change mitigation are nowadays widely recognized. Adequate management of these systems
increases their potential for recovering part of the carbon released into the atmosphere due to
deforestation in the world (Montagnini and Nair 2004). Therefore, agricultural production has the
potential to be less a problem and more part of the solution to problems related to climate change and
development (Hoffmann 2011).
The initial ndings of the project, reported in Table 4, show that, in comparison with primary
rainforest, traditional agroforestry systems based on cacao farming store 42 % of C (334 Mg C ha
1
)
and 56 Mg C ha
1
more than cacao monocultures (see, also, Torres et al. 2013).
The carbon content in air and root biomass shows that the cacao chakra system contains 896 %
more C than cacao monocultures (68.1 Mg C ha-1 and 7.6 Mg C ha
1
, respectively). This high
percentage of carbon storage in the chakra system corresponds to the diversity of trees used for
timber, most of which have a high commercial value, for example, chuncho [Cedrelinga

ue [Pollalesta discolor
(Kunth) Aristeg] (see Table 6). There is also a diversity of fruit trees, bushes, and palm trees that
form part of the local population gastronomic culture.
These ndings on stored carbon in air and root biomass in cacao chakras are similar to those
obtained by Ordoñez et al. (2011) in locations near the area of our study within the SBR. They
register (68.6 Mg C ha
1
) in chakra agroforestry systems with cacao trees that are 8 years old, on
average (Table 5).
These results show that, given the amount of carbon stored both in air biomass and in root biomass
in cacao, fruit, and timber trees, the potential of the traditional cacao chakra system to enter into the
carbon market is important. Also, participation in the carbon market could help to maintain other
components of the chakra system, which produce ecosystem services with no market value.
Contribution to the Conservation of Plant Species Diversity and the
Amazon Landscape
One of the main characteristics of the chakra system is the oral diversity and density of timber-
yielding species, which mostly regenerate naturally.
With regard to the oristic diversity at family, genus, and species levels, we found an average of
eight families, nine genus, and nine species in the chakra system. Meanwhile, in cocoa monoculture
farms, only one family, one gender, and two species were found (in average). These demonstrate the
contribution of the chakra with cocoa production system to the conservation of oristic diversity of
fruit and timber trees. In addition, having a variety of species, commonly used for food, medicine,
energy drink, craft, spiritual rituals, and multipurpose materials (Table 7), also shows its potential to
adapt to climate change.
In relation to density, the chakra system with cacao was found to have on average 170 timber and
fruit trees with a diameter greater than or equal to 10 cm at breast height (DBH). Figure 2shows the
number of trees identied in line with the DAP ranking.
A particular pattern of spatial distribution of timber tree species and fruit trees could not be
identied due to the absence of systematic practices for planting timber or fruit trees. These trees
grow in a process of natural regeneration from the dispersion of seeds caused by wind or from the

diversity of the fauna present in the system. As a general observation, it can be mentioned that
timber-yielding trees can be found in distances between 15 and 20 m apart (Figs. 3,4, and 5).
However, it is important to highlight that, at the time when producers engage in crop management,
timber species of commercial value are generally carefully managed. The management of tree
diversity in the chakra system (Table 6) shows how the Amazonian Kichwa population maintains
crucial information about plant resources from a solid popular knowledge of plant species and their
uses. Thus, it can be said that chakras are a model of biodiversity conservation; at the same time, they
provide ecosystem services for the livelihoods of local population.
Contribution of Cacao Chakras to Food Security and Climate Change
Adaptation
The effects of climate change on production systems are particular to each region. The number of
extreme weather events, droughts, oods, and temperature rise affects agriculture, especially mono-
cultures. Genetic diversity of production systems with high diversity of plants and animals is
a means to address climate change (Kotschi and von Lossau 2012).
In the Sumaco Biosphere Reserve, chakras are based on the cultivation of cacao, combined with
fruit trees and food plants, which also have the function to store carbon during their growth process.
This is the case of guabos (Inga spp.), grape tree (Pourouma cecropiifolia Mart.), hard chonta
(Bactris gasipaes Kunth), white cacao (Theobroma bicolor Bonpl.), and introduced fruit trees such
as achotillo (Nephelium lappaceum), cherimoya [Rollinia mucosa (Jacq.) Baill.], among others.
Given that, at 2010, there were about 12,500 ha of cacao-based chakra farms in the SBR, managed

by approximately 9,200 producers (Giza 2011), it can be said that the contribution of traditional
agroforestry to climate change mitigation is important (see, also, section Methodology).
Noteworthy, research supported by the German Development Cooperation (GIZ) on the contri-
bution of traditional agroforestry to local economies suggests that the chakra system substantially
supports rural livelihoods. Indeed, for producers from the Kallari Association in the SBR, it was
found that 42 % of the household monetary income comes from the sale of cacao and 37 %

corresponds to produce that contributes to food security, i.e., staple food produced and consumed in
chakras (GIZb 2011).
Table 7shows the main species of fruit trees, shrubs, and palms that are commonly found in
a chakra. These species contribute both to carbon sequestration and storage and the preservation of
local food culture. All species listed in the table correspond to the cacao-based chakras. Their
botanical identication and most popular use were veried through two sources: de la Torre
et al. (2008) and Ríos et al. (2007).
Edible plants found in chakras with cacao in the Sumaco Biosphere Reserve like banana (Musa
spp.), cassava (Manihot esculenta Crantz), pineapple [Ananas comosus (L.) Merr.], corn (Zea mays
L.), peanuts (Arachis hypogaea L.), lemongrass [Cymbopogon citratus (DC.) stapf], chili

and one mestizo population, according to Ríos et al. (2007). This highlights that the chakra system,
associated with a cash crop such as cacao, can be an option for carbon sequestration and climate
change mitigation; it also contributes to food security. Chakras with cacao also can be integrated into
wildlife corridors, connecting patches of primary or secondary forests while generating household
income (Torres et al. 2013). Therefore, they potentially contribute to local populationslifestyle in
harmony with nature. However, more quantitative approaches are needed in order to develop
concrete strategies for climate change adaptation.

Local Governance for Climate Change Management by Promoting Chakra
System with Cacao
The Ecuadorian Constitution of 2008 includes two specic articles for climate change management:
Article 413 (The State shall promote energy efciency, development and use of environmentally
clean technologies, practices and policies as well as diversied renewable energy of low impact on
and no risk for food sovereignty, ecological balance of ecosystems and the right to water) and
Article 414 (The State shall take appropriate and transverse measures to mitigate climate change by
limiting emissions of greenhouse gases, deforestation and air pollution). This mandate is
implemented through the National Development Plan for Good Living (20092013), in which

objective 4 includes a policy to promote the adaptation to and mitigation of climate variability with
focus on climate change.
In 2008, both legal instruments set up a framework for the First Forum of Cacao, established in the
city of Tena. This started an innovative process of land management of cacao elds based on
strengthening a space of coordination (the cacao round table MCFA) in the SBR (GIZa 2011).
Such a public space includes participatory governance principles for issues regarding mitigation of
and adaptation to climate change.
The SBR MCFA promotes the production of cacao on the basis of the chakra system. At the time
this chapter was nished (August 2013), the MCFA had 41 actors representing the social, public,
private, and cooperative sectors. Remarkably, 16 of them are representatives of local producers. The
MCFA works with a concerted strategy called faces of cacao; this includes (Chacón et al 2012)
(a) the agro-productive face, (b) the ecological face, (c) culture and tourism, and (d) avors and
smells. In this strategy, the ecological face addresses issues of climate change in chakras with cacao.
The MCFA is a local governance mechanism that helps to coordinate actions to mitigate climate
change through the cultivation of cacao. It has achieved to promote participatory processes that
address and guide a local agenda, where stakeholders, from public and private sectors, put in practice
their ideas and interests in local action plans. These are implemented on the basis of a single driving
scheme where all actors have the same rights to evaluate and decide on the principle of horizontality.
This model of management allows for particular and transparent contribution from each member
of the MCFA platform to collective action. Participation draws on the principles of inclusion and
interacting planning becomes practical action on the principle of complementarity. All these
consolidate, in practice, the implementation of climate-smart, socially, and ecologically sustainable
production systems.
Revival of the Amazonian traditional chakra system, adapted to a commercial produce that adds
value such as cacao, has facilitated the political understanding of sustainability both on productive
and climate change grounds. As a land management system, the Amazonian chakra is an example
that shows how adaptation of production systems based on traditional knowledge can contribute to
mitigate and adapt to climate change; therefore, it is useful for the promotion of sustainable
production patterns in other areas where traditional systems also exist.
Conclusion
This chapter reports ndings on the capacity of a traditional agroforestry system, called chakra, to
contribute to climate change mitigation and adaptation. The focus was particularly on the integrative
characteristic of such a system to harmoniously pursue the achievement of multiple goals. The
ndings suggest that chakras can be taken as examples of sustainable production that must be
preserved in order to tackle climate change effects in tropical zones. Chakras with cacao in the
Ecuadorian Amazon region provide diversied ecosystem services that can only be recuperated
through the recognition of local knowledge. Furthermore, it is within the chakra system where
decisions concerning harmonized landscapes, territory, and locally constructed processes of adap-
tation to climate change are made every day.
The ndings can guide policy makers and other stakeholders in their decisions on land-use policy
and measures to tackle poverty and climate change. In this way, the intention is to contribute to
making future policies more effective, thus better enabling local population to strengthen their
organizational capacity for climate change adaptation. Yet, encouraging dialogue platforms to
support local governance mechanisms, based on sustainable production systems, requires

transdisciplinary research focused on issues of sustainable climate change adaptation, that is,
combining climatic concerns with good livinggoals. Further, it requires a development strategy
that has the sustainable conservation of the rainforest as a main pillar and integrates local population
in the Amazon region territorial planning.

Introduction Cocoa is one of the main crops grown in Ecuador. The agricultural area dedicated to cocoa represents the largest area dedicated to a permanent crop the country. Dry bean production has grown at an average annual rate of 15% since 2014, mainly due to yield improvements and replacement of other crops. Several varieties of cocoa are grown, but production is dominated by two main varieties: “Cacao Fino y de Aroma” and clonal varieties (dominated by CCN-51). Cocoa, mainly in monocrop systems, is mainly produced on the Ecuadorian Coast (but also in the Highlands and Amazonia). This study presents a statistics-based LCA of the Ecuadorian cocoa value chain. Material and methods LCIs representing the various types of systems in each link of the value chain—i.e. the various types of farming systems, processing and distribution—were constructed in terms of representative production units. Sub-chains centred on different cocoa varieties and value-adding strategies were identified. Primary and secondary data were collected for the most representative system types, as defined in the actor typologies. Primary data were obtained via field visits and surveys, while secondary data were obtained mainly from statistical datasets of the National Institute of Statistics and Census. Impacts were computed following the European Commission's Product Environmental Footprint, while soil carbon turnover was modelled using RothC. Results and discussion Identified types of producers are subsistence and entrepreneurial small, medium, and large. Two post-harvest strategies were modelled: a volume-oriented one and a quality-oriented one. The main sub-chains identified are the volume/commodity-oriented one (which is dominantly based on cocoa which either does not undergo post-harvest, or which undergoes volume-oriented post-harvest activities) and the quality-oriented one. Across producer types, irrigation and negative direct field emissions are the most important factors, followed in importance by total energy consumption. Post-harvest and processing activities are dominated by energy expenditures. Sub-chains feature significantly different intensity of impacts, with the volume-oriented sub-chain (i.e. those privileging quantity over quality) featuring lower impacts than the quality-oriented ones. Conclusions The impacts of the value chain are comparatively lower, at least regarding climate change, than in other producing countries. Its agricultural phase generally exhibits low input pressure, contributes to climate change mitigation through high C sequestration in biomass that exceeds C losses due to land use change (e.g. deforestation), and does not seem to pose an immediate threat to biodiversity. Improvement initiatives do not necessarily imply intensification of production.
... The Ecuadorian Amazon covers an area of 116.604 km 2 , which represents 47% of the national continental territory (figure 2) (Torres, 2015). Precipitations are frequent and intense, around 3000-4000 mm annually, the average temperature is 25° and the topsoil is generally thin and prone to erosion (due to the intensive rains), namely when not completely covered by the natural dense vegetation (Vizcaino, 2009). ...
... Arevalo identifies it as varying between 2 and 7 years, while before it could largely exceed 10 years, which Vera-Velez et al. consider as ideal for integral regeneration (Arevalo, 2009;Vera-Velez et al., 2019). The dimension of individual chakras can vary between 0.25 and 1.5 ha for family chakras and 4 ha for productive chakras (Torres et al., 2015;Jarret et al., 2017). ...
... They are the keepers of most of the traditional ecological knowledge related to the Chakra, which is connected to a deep ability to interpret the natural signals and to maintain a relationship of reciprocity with the forest (Arevalo, 2009;Andy et al., 2012). Before the sowing of manioc, for example, they realise the ritual of "Lumupachina", to propitiate a good production, they realise a careful consociation with other plants, they can predict rains and days of strong sun by observing the presence of animals and their ways of singing and they can identify fertile and unfertile periods according to the moon's phases and the fluorescence of trees (GIZ, 2020;Torres, 2015). The "gift" (paju), which corresponds to the agricultural management ability associated with each specific plant, is traditionally passed from women to women by rituals of joint work. ...

In a context of climate crisis, the Amazon Forest is considered a key ecosystem for global climate regulation and biodiversity preservation. Indigenous populations inhabited the forest for centuries, developing extremely biodiverse agroforestry systems which favour the regeneration of the natural ecosystem. However, today the environmental and cultural richness of the Amazon is increasingly threatened by deforestation, in large part related to the advancement of the conventional agriculture frontier. The present research aims at proposing that empowering these traditional ecological systems could be employed by local and international development cooperation as a participatory strategy to promote sustainable development, and so to contribute to preserve the Amazonian ecosystem services and enhance food security. A case study of Chakra Kichwa Amazonica, indigenous agroforestry system of the Ecuadorian Amazon, serves to investigate concrete empowerment actions, to be eventually replicated in other areas of the Amazon Basin. This exploratory research concludes that empowering traditional agroforestry systems can be a valuable strategy to promote sustainable development in the Amazon Basin, but not itself sufficient to ensure a participatory approach.
... Traditional production systems have several attributes that contribute to sustainable development, such as high species diversity with strong environmental adaptability (Zhang et al., 2011) and resistance to pests and diseases (Flores-Delgadillo et al., 2011). They can act as instruments for resilience, mitigation, and adaptation to climate change (McCord et al., 2015;Torres et al., 2015Torres et al., , 2018Tesfaye and Tirivayi, 2020). Such systems can help manage risk and decrease rural poverty and food insecurity (Michler and Josephson, 2017;Waha et al., 2018;Lovo and Veronesi, 2019;Mustafa et al., 2019;Bellon et al., 2020) through providing income from local markets (Bellon et al., 2020) and nutrition and child health in impoverished rural households. ...
... These groups manage their own traditional agricultural systems, which are part of each cultural heritage and geographic origin, for their tangible and intangible assets (Rudel et al., 2002;Lu and Bilsborrow, 2011;Ima Omene, 2012;Torres et al., 2015;Zurita-Benavides, 2017). However, climate variability, deforestation, and poor land management practices have led local populations to depend on agrochemicals (Davis et al., 2012) or in the expansion of the agricultural frontier to increase incomes (Mena et al., 2006(Mena et al., , 2011Walsh et al., 2008). ...
... Their predominant traditional production system is the chakra, which today has been widely studied Vera et al., 2017;Coq-Huelva et al., 2018;Vera-Vélez et al., 2019) and is considered a combination of culturally specific means of biosocial construction (Coq-Huelva et al., 2017). It is characterized by its high level of biodiversity (Vera et al., 2017;Vera-Vélez et al., 2019) and a high number of fruit and timber trees (Jadán et al., 2015;Torres et al., 2015;Coq-Huelva et al., 2017Luzuriaga-Quichimbo et al., 2019), with the predominant crops being cocoa (Theobroma cacao L.), coffee (Coffea canephora Pierre ex A. Froehner), and to a lesser extent guayusa (Ilex guayusa Loes.) (Krause and Ness, 2017), alongside medicinal plants for healing purposes, spiritual rituals, handicrafts, and consumption (Coq-Huelva et al., 2017). ...

Although traditional agriculture carried out by ethnic groups is considered for its high biodiversity and important for food security and sovereignty, few studies have investigated the potential of these systems in the interest of promoting a sustainable agricultural development policy according to United Nations Sustainable Development Goals. Using the FAO's Sustainability Assessment of Food and Agriculture (SAFA) methodology, this study analyzed the sustainability of four traditional agricultural systems, three indigenous (Waorani, Shuar, and Kichwa) and one migrant settler populations in the Yasuní Biosphere Reserve (YBR) and identified synergies and trade-offs among the dimensions of sustainability. The results showed different dynamics in all dimensions of sustainability-specifically, trade-offs in the dimensions of good governance with environmental integrity and social well-being, economic resilience, and social well-being. It was identified that the differences in terms of sustainability are narrowing between the indigenous Shuar people's traditional agricultural systems and those of migrant settlers, which provides policymakers with specific information to design sustainable development policies and rescue traditional agricultural systems in the Amazon region.

El presente trabajo analiza el turismo científico en la comunidad San José de Payamino como potencial para lograr los objetivos de desarrollo sostenible (ODS). El estudio se realizó en la comunidad kichwa San José de Payamino ubicado en el cantón Loreto, provincia de Orellana, con una extensión de 17.000 hectáreas, formando parte de la zona de amortiguamiento del Parque Nacional Sumaco Napo Galeras (PNSNG) y la Reserva de Biosfera Sumaco (RBS). Se aplicó una encuesta a 62 hogares utilizando un cuestionario estructurado, así como talleres y entrevistas con la participación de actores claves involucrados. Para analizar las formas del Turismo científico TCi y los elementos de la cosmovisión indígena para lograr los ODS, se realizó una matriz de ponderación, donde se clasifican las formas de TCi y su relación con seis elementos de la cosmovisión indígena. Los resultados muestran que las actividades principales en los hogares se orientan a la cría de animales (pollos, gallinas, cerdos) específicamente para la alimentación y los cultivos cacao, café, naranjilla para la generación de ingresos monetario. Se determinó que las cuatro formas del TCi tienen afinidad con los seis elementos de la cosmovisión kichwa evaluados, y contribuyen al menos a 11 de los 17 ODS en la comunidad. Finalmente, estos resultados sugieren que las estaciones científicas pueden apoyar a las comunidades rurales en el buen manejo de sus recursos naturales, la generación de ingresos sostenibles y logros de los ODS.

... This agrees with (Moreno el al., 2013) from a study conducted in traditional agroforestry systems in Mexico. Traditional agroforestry systems present crops associated with banana area, coffee, national cocoa and CCN-51 with timber and fruit species interspersed with annual cycles, which for (Torres et al., 2014) determines that through the integration of trees on farms improves the agricultural landscape, diversifies and sustains production to increase the social, economic and environmental benefits of farmers at all levels. The most abundant family within the agroforestry systems was: Boraginaceae with 126 individuals followed by Moraceae with 70 individuals, data that does not agree with the research of (Zambrano, 2012) where the most dominant family was: Malvaceae followed by Arecaceae and the work done by (Chacón, 2017) the most abundant family was Leguminosae and Rutaceae. ...

Agroforestry systems are known for their potential to provide income and food security as well as various ecosystem services in a sustainable manner. Thus, the Chakra System – the traditional agroforestry system of the Kichwa people of the Ecuadorian province of Napo – should not be of overlooked for further development of the province, as it is located in one of the most biodiverse regions of the world and faces challenges like deforestation, soil degradation, and climate change. Since Napo experienced major socioeconomic and environmental changes over the last century, this study investigates how these developments impact the Chakra System and the role it plays in Napo Province. It provides insight into the history of Napo, giving background to the most prominent changes. An in-depth description of the traditional and contemporary Chakra System variations allows for an analysis of how the system changed with the framework it operates in. Subsequently, this paper outlines three alternative future scenarios by extrapolating these trends into the future to illustrate the potential impacts of current developments. On this basis, it analyzes the development of the role the Chakra System plays for Napo. Journal articles, conference papers, internet documents, census data, theses, atlases, and books concerning current, past and future matter were analyzed for this purpose. The Chakra System was identified to play a central role in balancing human needs with the maintenance of the ecosystem’s functionality. The changes Napo experiences placed new demands on the system. Thus, new functions (like monetary income generation) and features (like sedentarism) were added to the Chakra’s arsenal. Analysis showed that these developments did not change the balancing role of the Chakra System. Conversely, they increased the importance of this balancing act in the face of the upcoming developments and challenges within Napo. For the Chakra System to fulfill its role satisfactorily, its new functions and features need to be further developed and improvement. The framework it operates in needs to be adapted to it. Continuous research and funding will be needed to address the challenges and the potential the Chakra System and Napo Province face.

Tropical forests are recognized for their role in providing diverse ecosystem services (ESs), with carbon uptake the best recognized. The capacity of tropical forests to provide ESs is strongly linked to their enormous biodiversity. However, causal relationships between biodiversity and ESs are poorly understood. This may be because biodiversity is often translated into species richness. Here, we argue that focusing on multiple attributes of biodiversity—structure, composition, and function—will make relationships between biodiversity and ESs clearer. In this review, we discuss the ecological processes behind ESs from tropical humid and subhumid forests of South America. Our main goal is to understand the links between the ESs and those three biodiversity attributes. While supporting and regulating services relate more closely to forest structure and function, provisioning services relate more closely to forest composition and function, and cultural services are more related to structure and composition attributes. In this sense, ESs from subhumid forests (savannas) differ from those provided by the Amazon Forest, although both ecosystems are recognized as harboring tremendous biodiversity. Given this, if anthropogenic drivers of change promote a shift in the Amazon Forest toward savanna—the savannization hypothesis—the types of services provided will change, especially climate regulating services. This review emphasizes the importance of deeply understanding ecosystem structure, composition, and function to better understand the services ecosystems provide. Understanding that anthropogenic impacts on biodiversity occur through these three main attributes, it becomes easier to anticipate how humans will impact ESs.

The predominant aim of the current research has been to quantify and map the pattern of changes in land use coverage (LULC), using a variety of tools of geographic information systems. The study area comprises the southern zone of the Diversity and Life Zone (DLZ), located in the Yasuní Biosphere Reserve, within the western Amazonian lowland. The processes for conducting the LULC in the DLZ included 1) data collection and analysis, 2) remote sensing data processing, 3) thematic land cover and 4) transformation from raster to vector. The analysis period was of about ten years (2009–2018), with the use of Landsat 7−8 satellite images. The classified classes were forest, traditional productive system, herbaceous vegetation, infrastructure and water. It was determined that the herbaceous vegetation increased by 0.81%, as well as the surface of traditional productive systems by some 0.73%, while the forest decreased by 0.93%. Therefore, we may state that the LUCL allows different local and international actors to contribute in agri-environmental and conservation decisions in order to minimize deforestation within the study area.

Se estimó el almacenamiento de carbono de cinco usos de la tierra (cacaotales con árboles, bananales con árboles, plátano monocul-tivo, charrales y bosques de galería), el margen bruto y el costo de oportunidad de cambiar el uso actual del suelo hacia otros con mayor contenido de carbono en las fincas de Talamanca indígena, Costa Rica. Los usos de la tierra en las lomas almacenaron 22% más carbono total y 47% más de carbono en biomasa que los del valle. Los bosques de galería son los sistemas que más carbono almacenaron, seguidos de cacaotales con árboles, charrales, bana¬no con árboles y, por último, plátano en monocultivo. El suelo fue el mayor reservorio de carbono (27-74%), seguido de la biomasa arriba del suelo (15-57%). El plátano es el uso del suelo más ren¬table, con un beneficio neto de 798 US$ ha-1 año-1. Las plantaciones de cacao con árboles y arroz presentan beneficios negativos (59 y 14 ha-1 US$ año-1, respectivamente), pero permiten capitalizar la mano de obra familiar en zonas sin otras opciones de empleo. El cambio de platanales a otros usos del suelo para fijar carbono es poco factible, ya que el costo de oportunidad es muy elevado (20,8-50,1 US$ tC-1). Los cambios de cultivos de maíz o arroz a charrales y cacaotales son más atractivos por sus bajos costos de oportunidad.

The cocoa tree (Theobroma cacao L.) is cultivated typically in agroforestry systems in close association with a rich list of tree species and other useful plants on the same plot. Cocoa based agroforestry systems are credited for stocking significant amounts of carbon and hence have the potential to mitigate climate change. Since cocoa yields decrease non-linearly with increasing shade, a need is to design optimal cocoa agroforestry systems with high yields and high carbon stocks. We estimated the carbon stocked in a network of 229 permanent sample plots in cacao-based agroforestry systems and natural forests in five Central American countries. Carbon stocks were fractioned by both system compartments (aboveground, roots, soil, litter, dead wood – fine and coarse, and total) and tree use/form (cocoa, timber, fruit, bananas, shade and ornamentals, and palms). Cocoa plantations were assigned to a five-class typology and tested for independence with growing region using contingency analysis. Most Central American cocoa plantations had mixed or productive shade canopies. Only 4% of cocoa plantations were full sun or rustic (cocoa under thinned natural forest). Cocoa tree density was low (548 ± 192 trees ha−1). Total carbon (soil + biomass + dead biomass) was 117 ± 47 Mg ha−1, with 51 Mg ha−1 in the soil and 49 Mg ha−1 (42% of total carbon) in aboveground biomass (cocoa and canopy trees). Cocoa trees accumulated 9 Mg C ha−1 (18% of carbon in aboveground biomass). Timber and fruit trees stored 65% of aboveground carbon. The annual rate of accumulation of carbon in aboveground biomass ranged between 1.3 and 2.6 Mg C ha−1 y−1. Trade-offs between carbon levels and yields were explored qualitatively using functional relationships documented in the scientific and technical literature, and expert knowledge. We argue that it is possible to design cocoa-based AFS with good yields (cocoa and shade canopy) and high carbon stock levels. The botanical composition of the shade canopy provides a large set of morphological and functional traits that can be used to optimize shade canopy design. Our results offer Central American cocoa producers a rigorous estimate of carbon stocks in their cocoa plantations. This knowledge may help them to certify and sell their cocoa, timber, fruits and other goods to niche markets with good prices. Our results will also assist governments and the private sector in (i) designing better legal, institutional and policy frameworks, local and national, promoting an agriculture with trees and (ii) contributing to the development of the national monitoring, reporting and verification systems required by the international community to access funding and payment for ecosystem services.

A growing literature has identified agricultural expansion by small farmers in the tropics as an important cause of global forest clearing, yet institutional factors affecting small farmers' decisions have rarely been taken into account in empirical analyses. We examine the influence of context on household land use/cover change (LUCC) decisions and estimate a multilevel model of LUCC for forest, pasture, perennials, annuals and fallow in Ecuador's northern Amazon from 1990 to 1999. We draw upon four strands of theoretical research to test relationships and interpret the findings: the peasant pioneer cycle, the hollow frontier, forest transition theory, and household lifecycle theory. We also examine differences within the study region, viz., sub-regional differences, and use descriptive and empirical model results to show that LUCC is jointly influenced by natural resource endowments, population changes, and community context, which may be moderated by location via road access. Off-farm employment and finca subdivision, which are affected by changes in population, are also strong predictors of LUCC. Community context plays a statistically significant role in land use change, accounting for 10% of total variation in our models. From a theoretical perspective, therefore, models that fail to take into account the effects of context, particularly in rapidly changing frontier environments, are missing a key component in explaining LUCC, which may result in incorrect statistical inferences. From a policy perspective, the results of this research suggest that policies in the Amazon must be targeted not just toward farmers, but toward structural factors at the community level.

The carbon, phosphorus, and water cycles of a subtropical floodplain forest, and related ecosystem characteristics, were studied. Located at 750 m elevation in Puerto Rico (latitude 18@?N) the forest had 27 tree species, 3059 stems/ha, a basal area of 42.4 m^2/ha, maximum height of 17 m, and a leaf area index of 3.3. Palm (Prestoea montana) dominated the forest, and, with two other species, accounted for 68% of the dominance. Throughfall, stemflow, interception, runoff, transpiration, and evapotranspiration accounted for 81.6, 9.8, 8.6, 77.7, 13.7, and 22.3% of annual rainfall (3725 mm) respectively. The stand carbon storage was 28.77 kg/m^2, distributed as follows: aboveground 35.4%, vegetation 44.2%, soil to 1 m depth 55%, palms 10.9%. Vegetation biomass was partitioned as follows: leaves 9.8% (75% are palm leaves), wood 68%, and roots 21.8%. Net aboveground primary carbon productivity (NPP) was 876 g@?m^-^2@?yr^-^1. Average litterfall was 2.4 g@?m^-^2@?d^-^1 (palm leaves 32%, other leaves 39%, and wood 10%). Half-lives of decaying material were 188, 306, 462, and 576 d, respectively, for palm leaves still attached to the parent tree, dicotyledonous leaves, palm leaves on the ground, and palm trunks. Total organic carbon concentrations in stream water increased with increasing stream discharge (from 2 g/m^3 to 30 g/m^3). Watershed export of carbon was 50 g@?m^-^2@?yr^-^1 (including 12 g@?m^-^2@?yr^-^1 in the form of leaf litter). Mean P concentration in palm leaves (1.18 mg/g) was twice that in dicotyledonous leaves (0.64 mg/g). Compared to a rainfall phosphorus input to the watershed of 63 mg@?m^-^2@?yr^-^1, leaching from the canopy was high (167 mg@?m^-^2@?yr^-^1), as was the loss of P from the watershed (611 mg@?m^-^2@?yr^-^1). Phosphorus-conserving mechanisms included a high rate of retranslocation in palms (504 mg@?m^-^2@?yr^-^1). In spite of these mechanisms, there was a net P loss from the watershed that ranged from 136 to 544 mg@?m^-^2@?yr^-^1. Periodic flooding, poor soil aeration, intensive year-round rainfall, and low atmospheric saturation vapor pressure deficits are believed to be the main driving forces of the floodplain forest, which exhibits many characteristics typical of lowland rain forests and floodplain wetlands. Rates of NPP, litterfall, and biomass turnover (residence time of 14-17 yr) are faster than expected for the climatic conditions, whereas rates of wood production and storage of organic matter in the vegetation and soil profile are lower than expected for the climate.
