Impact of climate change on agricultural production in the Sahel. Part 2. Case study for Groundnut and Cowpea in Niger

In the last 30 years the climate of the West African Sahel has shown various changes, especially in terms of rainfall, of which inter-annual variability is very high. This has significant consequences for the poor-resource farmers, whose incomes depend mainly on rainfed agriculture. Van Duivenbooden et al examine the impact of current climate variability and future climate change on groundnut and cowpea production in Niger.
