| This study compares aboveground and belowground carbon stocks and tree diversity in different cocoa cultivation systems in Bolivia: monoculture, simple agroforestry, and successional agroforestry, as well as fallow as a control. Since diversified, agroforestry-based cultivation systems are often considered important for sustainable development, we also evaluated the links between carbon stocks and tree diversity, as well as the role of organic certification in transitioning from monoculture to agroforestry. Biomass, tree diversity, and soil physiochemical parameters were sampled in 15 plots measuring 48 × 48 m. Semi-structured interviews with 52 cocoa farmers were used to evaluate the role of organic certification and farmers’ organizations (e.g., cocoa... |

| Migration from the Bolivian Altiplano to the Amazonian lowlands poses a number of challenges related to climate change adaptation and disaster risk reduction. Alto Beni, located in the Bolivian Yungas at the interface between two altitudinal zones, is a critical area in this respect. Unsustainable land use practices are leading to soil erosion, shallow landslides, as well as forest and biodiversity loss. Settlers from the Altiplano see themselves confronted with an ecosystem that does not support the agricultural systems they were once used to. Soil degradation and government incentives have promoted migration further into the rainforest, creating pressure on local indigenous groups and biodiversity. The best-suited land use system for the fragile soils... |

| Cocoa based small scale agriculture is the basic livelihood of most farming families in the region of Alto Beni in the Bolivian Andes. Cocoa cultivation is affected by climate change impacts, soil degradation, pests and plant diseases, and insecure cocoa prices. From a sustainable development point of view, cocoa farms need thus to become more resilient. Resilience refers to the ability within a farming system to reduce the sensitivity to stress factors while maintaining productivity, the capacity for self-organisation, to learn, and to adapt to change. Resilience can be subdivided in the three features buffer capacity, self-organisation, and adaptive capacity. This study addresses differences in resilience of organic and non-organic cocoa farms, and the... |

| Cocoa production in Alto Beni, Bolivia, is a major source of income and is severely affected by climate change impacts and other stress factors. Resilient farming systems are, thus, important for local families. This study compares indicators for social–ecological resilience in 30 organic and 22 nonorganic cocoa farms of Alto Beni. Organic farms had a higher tree and crop diversity, higher yields and incomes, more social connectedness, and participated in more courses on cocoa cultivation. Resilience was enhanced by local farmers’ organizations, providing organic certification and supporting diversified agroforestry with seedlings and extension, going beyond basic organic certification requirements. |

| Die Agroforstwirtschaft kann zum Schutz des Bodens, der Biodiversität, zur Ernährungs- und Einkommenssicherheit sowie zur Resilienz gegenüber dem Klimawandel beitragen. Kakaobauern in Alto Beni in Bolivien setzen verschiedene Varianten von Agroforstsystemen ein, und viele haben die Bio-Zertifizierung. Um die verschiedenen Anbausysteme zu vergleichen und herauszufinden, was die Rolle der Bio-Zertifizierung ist, wurden für diese Studie Daten in Kakaoparzellen erhoben und Interviews mit Kakaoproduzenten durchgeführt. Neben der Biodiversität waren auch die Kakaoernten und die Einkommen der Familien höher, welche ein Agroforstsystem hatten. Die Interviews zeigten, dass die Bio-Zertifizierung die Kakaoproduzenten motivierte, Kooperativen zu gründen, die Wissen... |

| Cocoa-based small-scale agriculture is the most important source of income for most farming families in the region of Alto Beni in the sub-humid foothills of the Andes. Cocoa is grown in cultivation systems of varying ecological complexity. The plantations are highly susceptible to climate change impacts. Local cocoa producers mention heat waves, droughts, floods and plant diseases as the main impacts affecting plants and working conditions, and they associate these impacts with global climate change. From a sustainable regional development point of view, cocoa farms need to become more resilient in order to cope with the climate change related effects that are putting cocoa-based livelihoods at risk. This study assesses agroecosystem resilience under... |

| El cultivo del cacao en pequeña escala, sustento básico de muchas familias del Alto Beni, es afectado por los impactos del cambio climático. Para el desarrollo sostenible, es necesario que las fincas adquieran resiliencia: la capacidad de un sistema para reducir su sensibilidad hacia factores de estrés y perturbaciones, manteniendo su productividad, capacidad auto-organizativa, de aprendizaje y adaptación al cambio. Investigamos las diferencias en la resiliencia entre las fincas orgánicas y no orgánicas de cacao, y los rasgos significativos que inciden en la resiliencia socio-ecológica de los sistemas agrícolas del cacao. Definimos indicadores de resiliencia con expertos locales y productores durante un taller y con grupos focales. Los indicadores de la... |

| Improved organic farming methods that enable more sustainable use of natural resources are numerous and are applied in almost every region of this planet. However, when it comes to spreading and adapting these methods to specific ecological and socio-economic contexts, we know only little about what factors influence the learning processes involved. This study aims at a thorough assessment of factors that are enabling or hindering knowledge co-production in organic farming in general and of sustainable rice farming in particular. Following a qualitative multilevel analysis, special emphasis is placed on understanding how the socio-economic, cultural and ecological context is constituted (macro-level), how key stakeholder groups collaborate and enhance... |
