Strategies used to reduce the risk of desertification Desertification is not inevitable and with careful management of water resources, the soil and vegetation via tree planting we can limit the spread of deserts. Farmers were trained in laying out contours using a simple water tube level. Over the Horizon Migration to the EU. Less than 50 years ago land in this region of the Sahel was productive Savannah, but is now dry desert because of decades of climate change and over intensive farming, forestry and land degradation.
