This chapter presents an analytic framework to identify agricultural innovations that are sustainable and suitable for the poorest and most vulnerable parts of the population. The framework contains a set of tools to collect and evaluate information on appropriate innovations based on relevant criteria. It considers the dimensions of environmental resilience, economic viability, and social sustainability, as well as technical sustainability considering important properties of the innovation itself. Information on already available agricultural innovations was collected in ten countries in South and Southeast Asia, as well as from the national and international agricultural research communities. A composite sustainability indicator was constructed to compare the collected innovations and radar charts were computed to visualize their performance in each sustainability criterion.

In rural Ethiopia, people consume mainly cereals and pulses. Integrating vegetables into the multi-storey cropping system of the Yayu Coffee Forest Biosphere Reserve could improve nutritional health while reducing pressure on natural habitats in the biodiversity hotspot. The aim of the study was to assess the performance of cowpea under shade and its consumer acceptance as leafy vegetables. Trials compared continuous harvesting with uprooting, and food preference was tested. A baseline survey was conducted in four villages and revealed that cropping of vegetables in coffee plantations would be adoptable by 17% of farmers. The cumulatively harvested mean leaf yield (18.15 t ha−1) was significantly higher than the leaf yield of the uprooted cowpea (6.56 t ha−1). As many as 41% (52%) of participants liked cowpea dishes (very much). Based on the trial yields and the RDA, a 25 m2 cowpea plot could produce sufficient vitamin A for 2.1–4.6 adults, iron for 0.8–1.7, and vitamin C for 1.3–2.9 adults during six months. Cowpea was successfully cultivated below coffee, yielded most when repeatedly harvested and showed a high acceptance among consumers. The consumption of cowpea leaves from coffee forests could contribute to a balanced diet and improved nutrition.
