In Africa, climate change is reducing crop yields and productivity . Agricultural productivity growth has been reduced by 34% since 1961 due to climate change, more than any other region. Maize and wheat yields decreased on average 5.8% and 2.3%, respectively in sub-Saharan Africa due to climate change in the period 1974-2008. Farmers and pastoralists perceive the climate to have changed and over two-thirds of Africans perceive climate conditions for agricultural production have worsened over the past 10 years. Woody plant encroachment has reduced fodder availability.
