| In recent years, the limitations of top-down approaches for development-oriented research have become apparent. Therefore, scientists have started to explore alternatives such as participatory research. By involving many stakeholders throughout the different stages of innovation development, participatory research helps tackling the multi-faceted challenges the global food system is facing today. Since almost a decade, the Research Institute of Organic Agriculture (FiBL) has been running a large program called “Farming Systems Comparison in the Tropics” (SysCom) in Bolivia, India and Kenya. Besides maintaining four Long-Term farming systems comparison Experiments (LTE), Participatory On-farm Research (POR) is a strong component of SysCom. In POR, we aim... |

| Yams (Dioscorea spp.) are widely grown throughout the tropics. Three yam species constitute the staple for more than 60 million people in five West African coastal countries, where more than 90% of the world's production takes place. Here we give a general introduction to yams, including their origin and geographic distribution as well as different types of yams common in Africa and Asia, and outline their uses. However, the main body in this chapter pertains to the agricultural production practices, including information on climatic requirements, soil type and land preparation, propagation, agronomic practices, pests and diseases (and their control), harvesting, curing and storage. Finally, we elaborate on the need for future research, in particular on... |

| Increasing concerns about global food security, depleting fossil reserves and diminishing natural resources question the continuation of energy-intensive conventional agriculture and emphasize the importance of sustainable alternatives such as organic agriculture. Even though organic farming is more ecologically sustainable and often economically advantageous, widespread adoption is limited as farmers making adoption-decisions are faced with challenging trade-offs (e.g. lower yields in the short term, limited options for crop nutrition and pest control and non-existence of markets for organic produce). This highlights the importance of innovation platforms involving relevant stakeholders (farmers, researchers, extensionists, etc.) in decision-making... |

| Cadmium(Cd) uptake by cocoa has recently attracted attention, after the European Union (EU) decided to establish values for tolerable Cd concentrations in cocoa products. Bean Cd concentrations from some cocoa provenances, especially from Latin America, were found to exceed these values. Cadmium uptake by cocoa is expected not only to depend on a variety of soil factors, but also on plant and management factors. In this study, we investigated the influence of different production systems on Cd uptake by cocoa in a long-term field trial in the Alto Beni Region of Bolivia,where cocoa trees are grown inmonocultures and in agroforestry systems, both under organic and conventional management. Leaf, fruits and roots of two cultivars were sampled fromeach... |

| The debate on the relative benefits of conventional and organic farming systems is more topical than ever. The achievements of conventional high-input agriculture were largely brought about at the cost of deteriorating soil fertility; furthermore, they were based to a large extent on fossil fuels. Developing more sustainable farming practices on a large scale is of utmost importance. However, information about the performance of agricultural production systems under organic and conventional management in tropical and subtropical regions is largely lacking. This study aimed to assess agronomic and economic data from a long-term farming systems comparison trial under semi-arid conditions in central India. |

| The growing demand for cocoa beans and products worldwide has been met by expanding the area under cocoa production while productivity per hectare has stagnated at a low level of around 450 kg/ha per year in the last decade. Throughout the tropics cocoa has increasingly been cultivated in full-sun monocultures in order to maximize short-term productivity and profitability, which has been associated with soil erosion and degradation, biodiversity loss, as well as increased susceptibility to climate change impacts and pests and diseases. Dynamic agroforestry systems are an alternative production method which has long been practiced in Latin American countries such as Bolivia. Through mimicking natural forests, these systems offer multiple benefits such as... |
