ISFM innovation: Example of maize - pigeonpea (and vegetables) in Tanzania

  1. 1. ISFM innovation: Example of maize - pigeonpea (and vegetables) in Tanzania Job Kihara International Center for Tropical Agriculture (CIAT) Africa RISING ESA Project review and planning meeting 11 – 12 September 2019, Dar es Salaam, Tanzania
  2. 2. Interventions
  3. 3. Varieties Availability/access Affordability Quality seeds Suitability Quality of manure Access/availability Fertilizers (green)Manure GAPS (Intercropping) Soil and Water Conservation Healthy soils and productivity Knowledge gaps Right equipment Labour availability • Tied ridging • Forages/fodder • Cover crops • Contours (?) Constraints Current practices • Mbili Mbili • CSA options • Double up legume • Spatial configurations (Spacing/density) • 4R • Manure integration • Maize (Meru 513, 515, SC 627 • Pipegonpea Karatu and Mali R flows • Post harvest mgt. • Nutrition
  4. 4. Calculations Scaled effects: (value-min) (max-min) • Max for runoff (197 mm) and erosion (25 t/ha) from literature (Kihara et al. review) • Converted data: high value better, low worse • Prevalence Reduction • Runoff Runoff avoided
  5. 5. Technology benefits: with ISFM vs no-ISFM
  6. 6. Technology benefits: ISFM in vegetables
  7. 7. GAPS and research studies • Understanding risks, farmers perceptions and adaptation strategies to the risks (weather variability, market fluctuations) • Market linkages (collective marketing) • Technology use/disuse study • Representation of uncertainty Variations around means for the domains/indicators? Standard deviations? • Seasonal/weather variability Performance under contrasting seasons
