  • 1. System of Wheat Intensification (SWI) in Mali – West Africa 3 years of experience Erika Styger SRI International Network and Resources Center (SRI-Rice)
  • 2. Mali - Timbuktu region
    • Sahelo-Saharien and Saharien climate
    • 150-200 mm rain/yr
    • Annual mean Temp: 29.1°C (13°- 43°C)
    • Food Security: >70% communes are among most vulnerable in Mali
  • 3.  
  • 4. Irrigated Rice and Wheat in the Timbuktu region Village Irrigation Perimeter 30-35 ha - 1 motor pump Shared among 100 farmers 0.33 ha / farmers
  • 5. SRI Story in Mali 2007 - 2011
    • 2007: first farmer exploratory test: SRI: 9 t/ha vs 6.7t/ha

    • 2009: 450 farmers in 5 regions: 7.7 t/ha vs 4.5 t/ha

    • Problems: mortality, spacing too large (25cm x 25cm)
    • Labor reduction: 40 %
    • Irrigation water reduction: 30%
    SWI: 10.2 cm Traditional: 4.2 cm Panicle length Number of tillers 18.4 3.7
