Afforestation and reforestation of natural forests
In Sudan, sandy soils cover about 60% of the country area, mainly in the north, northwest and north-eastern parts. Heavy, cracking clay soils form a triangular central easterly plain which constitutes approximately 30% of the land. Afforestation and restoration of natural or remnant Forests will help to control the water cycle by regulating precipitation, evaporation, and flows. Layers of forest canopy, branches and roots will store and release water vapor, which controls rainfall. Deforestation weakens this process, leading to irregular rainfall patterns including drought and flooding especially in Sahel region.
