There is widespread consensus that agricultural technology has an important role to play for poverty reduction and sustainable development. There is less consensus, however, about the types of technologies that are best suited for smallholder farmers in Africa. While some consider natural...

Climatic risks are a major challenge for rural communities, especially those whose livelihoods directly depend on agriculture. Weather extremes affect crop productivity not only through the direct relationship between weather variables and yields, but also through the negative effects of such...

Do transgenic crops cause agrobiodiversity erosion? We hypothesize that they increase productivity and reduce production risk and may therefore reduce farmer demand for on-farm varietal diversity, especially when only a few transgenic varieties are available. We also hypothesize that varietal...
