Cowpea Production and Trade
Source: Langyintuo et al., 2003
- Adapted dry climate and cash crop- Rich in protein- 23%- 3.7 MT produced yearly-Global - 70% of world production in WCA- Over 500,000 MT traded annually
Callosobruchus maculatus
Pest control methods
Purdue Improved Crop Storage (PICS)
6O2 + C6H12O6 6CO2 + 6H20
Approach to Extension/Outreach
• Village training- demonstrations• Market demonstrations• FBO and Women groups training • Cowpea traders and processors• Media- Radio, TV, posters, etc.
Village Film

e
Target 28,778 villages Reached 30,995 villages by Dec 2011 More than 500 Market
demonstrations Over 150,000 households tested bag
Extension/Outreach achievements
Approach to PICS bags Supply Chain
Semi-wholesalers/Vendors
Manufacturers Distributors/wholesalers
Retailers/Roaming vendors
- Commercial radio messages support vendors- PICS business consultant help vendors improve sales
Achievement Supply Chain
From July 2007- Jan 20121,820,000 triple layer bagsRoughly 1000 vendors
Poor harvest- 2011 season
Quick adoption….… Profitable
Storage Margin: Mali.
Price of the PICS bag in Mali~ $2.30

Impact- Increase their income
- Avoid health hazard - Improve food security
- Improve nutrition

Key constraints to adoption of triple layer bags
Partnership improves Availability of Post-harvest Technologies
Challenges S. Chain:•Weak legal system•Limited capital=>Strengthening social relations
CRS- Purdue in Niger, 2011
More partnership needed!
1. Does PICS bagging stop the insect problem?
2. Is grain moisture a problem?
3. Will seed stored in PICS bags germinate?
4. Are processing, cooking time, etc. affected?
5. Would PICS intervention be economical?
Research on other Crops- Underway:
