1. Post-harvest Technologies to Maintain Grain and Seed Quality Dieudonne Baributsa Purdue University Regional Knowledge Sharing Meeting Washington, DC November 13 – 15, 2012

2. 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 Time Initial1 months2 months4 months Population 5 Insects50025,0001,250,000

3. Pest control methods

4. Purdue Improved Crop Storage (PICS) 6O 2 + C 6 H 12 O 6  6CO 2 + 6H 2 0

6. 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 Cellphone

7.  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

8. 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

9. Achievement Supply Chain From July 2007- Jan 2012 1,820,000 triple layer bags Roughly 1000 vendors Poor harvest- 2011 season

10. Quick adoption….… Profitable Storage Margin: Mali. Price of the PICS bag in Mali~ $2.30

11. Impact - Increase their income - Avoid health hazard -Improve food security -Improve nutrition Maradi- Niger, 2010 Zinder- Niger, 2010 Ejura- Ghana, 2010

12. Key constraints to adoption of triple layer bags

13. 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!

14. 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:
