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

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

Technology benefits: with ISFM vs no-ISFM

Technology benefits: ISFM in vegetables

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
