Farm-scale explorations: Trade-off analysis
Falconnier 2015
10. • Many scenarios, using limited data, to quickly explore options
• Input data:
• Household survey at district level for yields, input costs
(AfricaRISING baselines), market survey for crop prices
• Rapid characterization of population of 109 farm
households in 3 villages (crop areas, livestock and
equipment), plus detailed characterization of 19 farms
based on types
• Calculated income from crops and food self-sufficiency for
each farm in several scenarios
11. • Yields
• 50th percentile (median) yields [MARBES]
• 90th percentile (best farmer practice) yields [MARBES]
• Experimental potential yields [ICRISAT/IER]
• Prices
• Averaged market prices from monthly market survey in
2014-2015
• Calculated income and food self-sufficiency
12. • Current crop allocation
• Optimized crop allocation
• Maximize gross margins
• Meet household calorie requirements with staple grains
• Maize area < twice cotton area (fertilizer availability
constraint)
• Crop area expansion

≥100% food
self-sufficient
Median 91% 79%
Best farmer 99% 99%
Potential 99% 99%
• Median yields: most farms self-sufficient
• All other scenarios: all but one farm is self-sufficient
16. What can we learn from simple scenarios?
• “Rapid prototyping” of farm
designs to explore potential
• Estimating cost-benefit of a
new technology should be a
first step not a last step
• Staple crop improvement
research should target food-
insecure households
• Livestock and off-farm income
income sources are important
for improving livelihoods
17. Typologies for Targeting and Scaling
• Simple indicators allow researchers to place
farmers within types
• Important to target a diverse group of farmers for
testing technologies
• Farmer evaluations can aid in analysis of
variability and in targeting technologies to types
• Ex-post typologies based on initial adoption can
be useful for scaling

21 options, assessed for yield and gross margin
Point out that there’s a difference between household and compound types – how to look compound -> household -> individual and what information you get at each level
Decisions re eg what goes on which soil type after which crop are made IN MALI at COMPOUND level by a chef des terres
Started with cluster analysis and then developed a decision tree so it becomes easy to classify farmers in the field
Replacing %ages of area with a new option
Rapid characterization
19 farms from rapid characterization
Crops: cotton maize gnut rice
Farmers are near optimal income levels now. Don’t gain much from optimization at current yields, a little more at 90th %ile, potential/opt potential
10 cases where optimized potential yields > gold mining
Farmers are near optimal income levels now. Don’t gain much from optimization at current yields, a little more at 90th %ile.
Groundnut and cowpea are potentially profitable options that have other benefits
