  • 3.
    • CONTEXT
    • > Temperatures will increase (2-3° C?)
    • > Rainfall will diminish and become more erratic
    • Crop yields will decline ( - 20%?)
    • Population will double every 20 years
  • 4. Niger: 15 million inhabitants in 2010 30 million in 2030 (every day + 1500)
  • 5. THE 1968 – 1973 DROUGHT ☹ A DROP IN RAINFALL OF 200 mm (about 30%) ☹ CHANGE IN RAINFALL CHARACTERISTICS ☹ STRONG DEGRADATION OF NATURAL RESOURCES ☹ LOW AND DECLINING CEREAL YIELDS (≤ 400 kg/ha)
