5. Introduction
Extreme climatic events, such as
droughts and floods, as well as chang-
es in the mean climate, have a direct
effect on crops and livestock and, thus,
people’s livelihoods. Food security is at
risk, particularly in sub-Saharan Africa
where local production remains largely
rain-fed. Given that climate variability
