  • Desertification in the Sahel
    • Causes
    • Management Strategies
      • Mali
        • 'Jatropha curcas' is grown as hedges around food crops. It can grow in poor quality soils and isn't eaten by animals.
          • Oil from the plant can be sold, providing a source of income
          • The roots of the plant help bind soil together and help prevent erosion.
          • The plant can  be burnt as fuel, reducing the need for deforestation.
        • Solar cooking uses mirrors to cook by reflecting the sun's rays and concentrating them in an area- reduces deforestation.
        • People are taught to look after trees and the environment
      • Chad
        • New stoves run on manure instead of wood, reducing deforestation.
        • NGOs have launched schemes to reduce soil erosion by educating villagers about the importance of maintaining vegetation and helping them grow and plant seedlings.
          • Also promote co-operation between villages to avoid over-exploitation of resources.
      • Ethiopia
        • Over one million trees are being planted in Ethiopia's rift valley
      • Niger
        • NGOs are providing farmers with free seeds of plants suitable for growing in arid conditions.
          • These plants grow extensive root systems that help hold the soil together. Long roots also mean the plants can access water deeper in the ground and are less vulnerable to drought.
      • Sudan
        • A more efficient version of the mogogo (traditional stove) has been introduced. This stove uses 50% less wood and so reduces the need for deforestation.
          • Funding from NGOs and international aid agencies
          • Senegal
            • The 'Great Green Wall'- a 15km belt of trees will be built to combat the spread of the desert.
      • Eritea
        • A more efficient version of the mogogo (traditional stove) has been introduced. This stove uses 50% less wood and so reduces the need for deforestation.
          • Funding from NGOs and international aid agencies
          • Senegal
            • The 'Great Green Wall'- a 15km belt of trees will be built to combat the spread of the desert.
      • Burkina Faso
        • Drip irrigation- dripping water directly to roots- reduces salinization and water waste.
  • NGOs have launched schemes to reduce soil erosion by educating villagers about the importance of maintaining vegetation and helping them grow and plant seedlings.
    • Also promote co-operation between villages to avoid over-exploitation of resources.
