Crop adaptation to climate change in the semi-arid zone in Tanzania: the role of genetic resources and seed systems

Rural livelihoods relying on agriculture are particularly vulnerable to climate change. Climate models project increasingly negative effects on maize and sorghum production in sub-Saharan Africa. This paper presents a case study of the role of genetic resources and seed systems in adapting to climatic stress from the semi-arid agroecological zone in Tanzania.
