Towards sustainable & productive farming systems for Africa: experiences and lessons from SIMLESA

  1. 1. Towards sustainable & productive farming systems for Africa: experiences and lessons from SIMLESA Mulugetta Mekuria SIMLESA Program Coordinator CIMMYT Southern Africa Regional Office, Harare, Zimbabwe
  2. 2. The Problem ComplexLow productivity Scarce biomass Land degradationClimate variability Poor markets Limited resources Food insecurity
  3. 3. The Potential: closing the yield gap
  4. 4. A Response: SIMLESA in actionWithin the CAADP framework, SIMLESA is increasing maize and legume yields by 30% through: Conservation agriculture practices Improved maize & legume varieties Better markets & value chainsIt will reduce yield risks by 30%Enhancing capacity & sustainabilityTo benefit 650,000 households Mrs Grace Malaichi CHAMPION FARMER,Facilitating spillovers to the region MALAWI
  5. 5. Where is ‘SIMLESA-10’ working?
  6. 6. SIMLESA Results on the Ground: 7 Increased maize yield from CA in Malawi Farmer practice 6 Mean maize ggrain yield (t ha-1) Conservation Agriculture 5 4 3 2 1 0 ETH KEN TAN MAL MOZ ETH KEN TAN MAL MOZ WET AREAS DRY AREAS Complex interactions: Rainfall × Soil × Tillage × Residue cover × inputs etc
  7. 7. SIMLESA Results on the Ground: benefits of CA in Ethiopia 40% Higher returns 54% Lower variable costs 1800 40000 Plowing 1600 35000 1400 30000 Cultivation 1200 Cost (birr ha-1)Return (birr ha-1) 25000 1000 Herbicide 20000 800 15000 600 Labour for row 10000 400 making 5000 200 Labour for herbicide 0 0 application CA FP CA FP
  8. 8. Scaling out: The weakest link in the R&D ContinuumIn country• Strengthening and replicating innovation platforms• Build technical capacity at all levels• Build capacity in partnership formation – Public private partnershipsAcross the region• Accelerating spillovers across countries – Ethiopia/Kenya to Rwanda/Burundi/Uganda/South Sudan – Tanzania/Malawi/Mozambique to Zambia/Botswana
  9. 9. Further Research Gaps• Integrated soil fertility management for CA• Integration of crop-livestock systems for CA – Forage/fodder legumes • Post harvest technology, storage and processing, food quality • Policy options for sustainable intensification • Resilience enhancing and risk reducing technologies – Stress tolerant QPM – Herbicide resistant maize and legumes – Cell-phone based insurance
  10. 10. Take Home Messages• Sustainable intensification through CA in Africa is not only necessary but urgent• Phased intensification across farming systems• Focus on impact pathways, innovation platforms and systems integration
