North Africa has a Mediterranean climate with hot dry summers and cool wet winters. Large area of the land of countries like Libya, Morocco and Egypt are classified as deserts or semi-desert and land use is governed by water availability. Soil loss from wind and water erosion and overgrazing of the steppes by livestock are common immediate cause of desertification. Over the last century there has been a decrease in rainfall throughout the Mediterranean region. Climate change predictions for North Africa show rising temperatures with potentially grim impact on the region's already stressed resources including food and water.
