The Sahel region of Africa is experiencing unprecedented warming and drought in 40 years. This was stated today, scientists in the report "Safety of life support: climate change, migration and conflict in the Sahel", released at the ongoing Durban / South Africa / 17 conference, the UN Framework Convention on Climate Change / UNFCCC /. They used a new surveying techniques to determine the most vulnerable areas in the Sahel — the area surrounding the Sahara desert.
In the 17 countries of the Sahel, which stretches from the Atlantic Ocean to Lake Chad, with 1970 registered significant changes in average temperatures, climate, rainfall, is indicated in the document. For example, the average temperature has risen by 1 degree Celsius, and in eastern Chad and northern Mali and Mauritania — and a half-two degrees. Increased frequency and magnitude of floods in southern Burkina Faso, western Niger and northern Nigeria.
Climate change and the reduction of natural resources combined population growth exacerbate the struggle for pasture and water sources, the report said. In this nomadic Saharan offensive pressure shift in their movements more and more to the south. The peasants in the fertile coastal plains competing with them in the struggle for the land, which leads to increased conflict and tension, particularly off the coast of Lake Chad dries quickly.
Chad, Mali, Mauritania and Niger have experienced over the past 20 years 6-10 drought, and some of their parts — 11-15, states the document. Many communities transition to a mixed type of farming, combining agriculture and animal husbandry.
