Maize legume Intensification – case studies from Malawi

  1. 1. Maize legume Intensification – case studies from Malawi Munyaradzi Mutenje International Maize and Wheat Improvement Center (CIMMYT) Africa RISING ESA Project review and planning meeting 11 – 12 September 2019, Dar es Salaam, Tanzania
  2. 2. Theme 2: Maize legume Intensification – case studies • Profile technologies of host farmers – ( adoption & adaptation, impact at farm scale) • Hypotheses: • Mother trial farmers are more likely to adopt the technologies • Farmers that have adopted a combination of SAI technologies are more resilient to shocks • Baby trial farmers follow up ( adoption and adaptation) • Baseline follow up ( IFPRI & MSU)
  3. 3. Strategic approach & methodology • Scaling out strategy – Mother baby trials • 6 mothers per community & 12 babies per mother • 2 contrasting agro-ecological regions • Main technologies/ treatments to be compared • Tillage systems - Conventional with tied ridges - Conservation agriculture • Cropping systems - Maize in doubled up legumes rotations - Maize- legume intercropping - Maize drought tolerant varieties - Climbing vs non climbing bio-fortified beans • Fertiliser regimes
  4. 4. Cluster villages and “mother and baby” trials Village of 100-200 households Good extension officer Vibrant and interested farmers Accessible site Distance 2-3 km
  5. 5. Strategic approach & methodology • Detailed case study looking of the SAIF 5 domains at farm scale • Select one champion mother in each of the agro-ecological zones • Randomly select one baby and non- adopter within the same vicinity
  6. 6. Data required 1. Mothers • Social & Human domain • technologies adopted and adapted for the five domains • integration of impacts at farm scale 2. Babies • technologies adopted & adapted 3. No Adopters whole farm enterprise analysis Livelihood analysis
