What are examples of human causes of desertification in Sudan's Dafur Region (part of Sahel)?

1. Overgrazing: In the Dafur Region of Sudan, decades of overgrazing of livestock by local communities have significantly diminished the grasslands, making it more difficult for crop production. Additionally, overstocking of animals has led to an increase in soil compaction, preventing rainwater from soaking into the ground. 2. Unsustainable agricultural practices: The combined effect of population growth and environmental degradation has caused widespread soil erosion, which has further reduced the fertility of the soils, leading to reduced crop yield. Unsustainable agricultural practices, such as the cultivation of fragile slopes, have also contributed to desertification in the region, as they cause further soil erosion and loss of vegetation cover. 3. Poor land use management: Poor land use management, such as deforestation, has further decreased the region’s soil fertility and led to the encroachment of the desert. The cutting of trees has led to the depletion of plant nutrients, and has also prevented rainwater from seeping into the soil, leading to further land degradation.
