Description:
A majority of the population in sub-Saharan African lives in rural areas, where income and employment depend almost entirely on rain-fed agriculture. This population is today at high risk. Sub-Saharan Africa already has a highly variable and unpredictable climate and is acutely vulnerable to floods and droughts. A third of the people in the region live in drought-prone areas, and floods are a recurrent threat in several countries. With climate change, large parts of the region will become drier, increasing the number of people at risk of hunger and poverty by tens of millions. Climate change is already affecting the region. Reduced rainfall across the Sahel, an increase in the incidence of drought and greater volatility are among the current symptoms. But the future points to far more extreme changes: warming between 0.2°C and 0.5°C per decade, with 10% less rainfall in interior regions under intermediate global warming scenarios, and water losses increased by rising temperatures. ...
