However, climate change will not have uniform impacts on water resources across the continent. impacts, climate change remains a long-term threat unlike any we have faced. They also include the economic and social changes which stem from living in a warmer world. As our climate changes, droughts, floods, melting glaciers, sea-level rise and storms intensify or alter, often with severe consequences. Climate change impacts the water cycle by influencing when, where, and how much precipitation falls. The African continent has been identified as particularly vulnerable to the changing climate due to its envisaged low adaptive capacity and vulnerability (Callaway, 2004).The southern African region is regarded as one of the most vulnerable regions in Africa (IPCC, 2007b).Within the climate change matrix, water resources are at the epicentre of projected climate change impacts. A recent study by the International Food Policy Research Institute found that more than half the world's population and approximately half of global grain production will be at risk due to water stress by 2050. Many states in the MENA Region have already begun to experience changes in precipitation levels due to climate change. The African countries are particularly exposed and vulnerable to the negative impacts of climate change, with important impacts on water resources and hydrological systems, water availability,. 46 participants attended, coming mainly from North America and Europe.
