Adapting to Climate Change in Africa's Drylands: From Research to Action

  1. 1. ADAPTING TO CLIMATE CHANGE IN AFRICA’S DRYLANDS: FROM RESEARCH TO ACTION
  2. 2. STUDY AREAS
  3. 3. <ul><li>CONTEXT </li></ul><ul><li>> Temperatures will increase (2-3° C?) </li></ul><ul><li>> Rainfall will diminish and become more erratic </li></ul><ul><li>Crop yields will decline ( - 20%?) </li></ul><ul><li>Population will double every 20 years </li></ul>
  4. 4. Niger: 15 million inhabitants in 2010 30 million in 2030 (every day + 1500)
  5. 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)
  6. 6. Vegetation in Galma in 1975 and 2003 2003 1975
  7. 8. NEW agroforestry parklands in Zinder dominated by Faidherbia Albida
  8. 9. The Barahogon are responsible for managing these on-farm forests on Mali’s Seno plains
  9. 11. 1990 REHABILITATION OF BARREN LAND 2004 Demi lunes Combretum glutinosum Zaï Techniques simples Piliostigma reticulatum Impacts importants
  10. 12. In Batodi water levels in wells increased by 14 m in 10 years (1994 – 2004)
  11. 13. A FIELD REHABILITATED IN 1988 (O.Kindo)
  12. 14. THE SAME FIELD IN 2008/LE MEME CHAMP EN 2008
  13. 15. Natural regeneration in Tigray (about 1 million ha) and in Zinder (NIGER)
  14. 16. Natural regeneration and water harvesting upslope……
  15. 17. … .have recharged groundwater levels downslope……..
  16. 18. … and expanded irrigation
  17. 19. … which contributes to food security in drought years
  18. 20. African Re-greening Initiatives: build on existing successes in re-greening to adapt to climate change, improve food security……..
  19. 21. AFRICAN RE-GREENING INITIATIVES OPERATIONAL IN: BURKINA FASO (since June 2009) MALI (since June 2009) SOON OPERATIONAL IN: NIGER (2010) ETHIOPIA (2010)
  20. 22. Is it possible to improve the livelihoods of millions of farmers in Africa ? Yes, it is !!
