Post-harvest Technologies to Maintain Grain and Seed Quality Dieudonne Baributsa Purdue University Regional Knowledge Sharing Meeting Washington, DC November 13 – 15, 2012
Cowpea Production and Trade Callosobruchusmaculatus 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
Purdue Improved Crop Storage (PICS) 6O2 + C6H12O6 6CO2 + 6H20
Approach to Extension/Outreach Cellphone • Village training- demonstrations • Market demonstrations • FBO and Women groups training • Cowpea traders and processors • Media- Radio, TV, posters, etc. Village Film
Extension/Outreach achievements • Target 28,778 villages • Reached 30,995 villages by Dec 2011 • More than 500 Market demonstrations • Over 150,000 households tested bag
Approach to PICS bags Supply Chain Distributors/ wholesalers Semi-wholesalers/ Vendors Retailers/ Roaming vendors Manufacturers - Commercial radio messages support vendors - PICS business consultant help vendors improve sales
Achievement Supply Chain From July 2007- Jan 2012 1,820,000 triple layer bags Roughly 1000 vendors Poor harvest- 2011 season
Quick adoption….… Profitable Price of the PICS bag in Mali~ $2.30 Storage Margin: Mali.
Impact • - Increase their income • - Avoid health hazard • Improve food security • Improve nutrition Maradi- Niger, 2010 Zinder- Niger, 2010 Ejura- Ghana, 2010
Partnership improves Availability of Post-harvest Technologies CRS- Purdue in Niger, 2011 Challenges S. Chain: • Weak legal system • Limited capital =>Strengthening social relations More partnership needed!
Research on other Crops- Underway: • 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?
