Stuvia is a great platform for students to share their knowledge and hard work&period; By helping others by offering your own notes and summari.... Moreover, the fundamental long-term problem remains: the Sahel is always food-insecure, even when harvests are good. What is really needed is development aid, which involves educating the local community in farming practices. The onset is usually in June, with the majority of the rain falling between July and September. This method preserves the topsoil and has improved farming and food production in the village. Overcultivation: the land is continually used for crops and does not have time to recover eventually al the nutrients are depleted (taken out) and the ground eventually turns to dust.
And in northern Mali the risks of food insecurity remain high, because of the conflict between jihadist militant groups and the forces of the government and France and their African allies.

Human activities such as overgrazing, overcultivation and the collection of firewood can lead to desertification [desertification: The spread of desert conditions in arid regions due to human activities, drought or climate change. Fish were more likely to die because of low flow, low oxygen levels and higher water temperatures. This video shows the Sahel region south of the Sahara is at risk of becoming desert. It becomes a vicious circle and can result in many deaths, especially among infants and the elderly. Earn hundreds of pounds each month by selling your written material to your fellow students. Food and water shortages have left a trail of death and destruction in the Sahel [Reuters]Between the vast Sahara Desert and the dense foliage of the African Rainforest is a band of semi-arid grassland.
