  2. 2. RE-GREENING IN THE SAHEL:BUILDING RESILIENCE ANDIMPROVING FOOD SECURITY
  3. 3. Vegetation in Galma in 1975 and 2003 1975 2003
  4. 4. Farmer-managed re-greening inNiger  5,000,000 ha re-greened in 20 years (no recurrent costs to governments)  200 million new trees (not planted)  additional cereal production/year: 500,000 ton  2.5 million people fed  1.25 million farm households involved
  5. 5. One million ha dominated by Faidherbiaalbida: improved soil fertility andmore fodder
  6. 6. Grain surplus Kantché Department(Zinder/Niger). 350,000 inhabitants;high on-farm tree density  2007 + 21,230 ton  2008 + 36,838 ton  2009 + 28,122 ton  2010 + 64,208 ton  2011 + 13,818 ton Source: National Committee for the Prevention and Management of Food Crises and FEWS Quoted by: Yamba and sambo (2012)

  11. 11. MULTIPLE IMPACTS OF RE-GREENINGINCLUDE:☛ IMPROVED FOOD SECURITY☛ ADAPTATION TO CLIMATE CHANGE☛ MITIGATION OF CLIMATE CHANGE☛ POVERTY REDUCTION☛ MORE FIREWOOD☛ MORE FODDER☛ REDUCTION OF CONFLICTS
  12. 12. VEGETATION TURNS DOWN THE HEAT
  13. 13. Some lessons  Farmers invest in on-farm trees when they have exclusive rights to their trees  Vital contribution from governments: lowering barriers to millions of farmers to invest in trees (national legislation, policies, incentives)  More people, more trees
