Additionally, southern Africa is likely to experience a 10 per cent rainfall decrease and more frequent drought, while East Africa is expected to see rainfall increases in the north and decreases in the south. Increasing occurrences of high rainfall events and flooding are also anticipated (Christensen et al., 2007).

 

However, climatic change is just one stressor among many complex, interacting and dynamic factors that influence smallholder farming households in SSA. Other factors include: population growth, urbanisation, education, health, especially HIV and Aids, financial service provision and market changes. Vulnerability to climate change and adaptive capacity is determined by a similarly wide combination of interacting socio-ecological factors.

Post-harvest systems

Post-harvest systems are diverse, reflecting the varied nature of the people, place, focal crop or product and the different activity stages involved. Post-harvest systems are influenced by the activities and interactions of many different players. An agricultural innovation systems perspective provides an analytical framework with which to examine technological and institutional change in post-harvest systems; identifying the players and factors affecting demand for, and use of, existing and new post-harvest and climate change knowledge.
