Some of the most profound and direct impacts of climate change in southern Africa over years have been droughts, fluctuations in annual rainfall, extreme temperatures and floods. These have resulted in low and unstable food production, especially maize which is the staple food in most Southern African countries. Furthermore, research suggests that 30% of threatened plant species will be critically endangered or extinct due to drought, thus further worsening food availability, accessibility and stability in the region. Drought is therefore is assumed to be the major obstacle to the achievement of food security in Southern Africa. Agroforestry is emerging as the promising option to sustain agricultural productivity and livelihoods of farmers. We discussed the need for further selection and releasing new tree germplasm with superior capacity to adapt to the changing climatic and ecological conditions in the region. Innovative mechanisms to further enhance the contribution of agroforestry to climate change mitigation and adaptation are examined.
