Crisis in Africa's drylands: the promise of agroforestry


Published on

The recent events in Mali, and before that in Sudan, Somalia and other dryland countries of Africa, all happened in areas where food insecurity coincides with low education, growing populations and recurrent droughts. Prof Garrity shows how tackling the root cause of these issues - low agricultural productivity - will, by kindling economic growth, boost stability in these countries. His favourite saying? "Hungry people are angry people".

Crisis in Africa's drylands: the promise of agroforestry

  1. 1. The Crises of Africa’s Drylandsand the Promise of Agroforestry Dennis Garrity UN Drylands Ambassador Distinguished Board Research Fellow World Agroforestry Centre
  2. 2. Perfect Storm of Challenges in the Drylands • Rainfall is becoming more erratic and extreme.  • Temperatures are increasing, intensifying crop stress. • Soil fertility is further declining in many regions.• Inorganic fertilizers are increasingly expensive.• Population growth rates remain estremely high•  Farm sizes are rapidly declining. Farming is expanding into more marginal lands.
  3. 3. Reversing Desertification throughFarmer-Managed Natural Regeneration Southern Niger in the 1980s
  4. 4. The albida halo effect• Microclimate buffering• Soil fertility improvement
  5. 5. Creating a Climate SMART and Productive Agriculture with fertilizer and fodder trees

  7. 7. Major agroforestry regions in West Africa and directions of expansion
  8. 8. Adaptation of fertilizer recommendation to local conditionswith strategic application of nurientsOther Successes:•Local fertilizer packaging andblending•Target input Vouchers•Legume-cereal rotation orintercrop•Participatory approaches Application of fertilizers in the seed holes at planting time
  9. 9. Microdose Control

  12. 12. Scaling up Evergreen AgricultureIntegrating Biofertilizer and Fodder Trees into croplandsto restore and build more productive and drought resilient farmingand livestock systemsRainwater Harvesting with an accent on simple techniques forenhanced crop production, water recharge and water retentionintegrated with agroforestry.Integrated Soil Fertility M anagement with fertilizermicrodosingwith enhanced organic nutrient sources combined withagroforestry.
  13. 13. 17 Countries are engaged in EverGreen Agriculture Farmer Managed Natural Regeneration Conservation Agriculture with trees Trees interplanted in conventional tilled cropland Farmer Managed Natural Regeneration + Trees interplanted in conventional tilled cropland
  14. 14. Conclusions – Way Forward• There is a ‘Convenient Convergence’ – Create a Climate Resilient Agriculture through EverGreen Agriculture for land regeneration and food security on small-scale farms.• The approach has taken root in Africa, and is spreading rapidly.• Millions of smallholders are adopting effective land regeneration methods• Many nations are creating the policy and institutional environments to favor adoption
