Farmers have already felt the first effects of changing climatic conditions. In 2006, the production of maize, the main staple in the region, fell short by 2.18 million metric tonnes due to droughts in Namibia, Mozambique, Swaziland, Zimbabwe and South Africa. Flooding in the Zambezi basin has been affecting Angola, Botswana, Namibia, Zambia and Zimbabwe, said Musvoto. Both Seychelles and Zambia have been experiencing a mixture of increased droughts and increased flooding. The World Food Programme (WFP) announced in January that about 6.5 million people will need food aid in Southern Africa by the end of April.
