Funded by the Bill & Melinda Gates Foundation, IPIM is a program directed by Dr. John Sanders​ of Purdue University's Department of Agricultural Economics and Co-Director Botorou Ouendeba to ease the strain of hunger in the Sahel. Africa's Sahel Region faces many c​hallenges, the first of which is an ongoing food crisis with risk of hunger a real concern. Learn more about how IPIM is working to improve agricultural technology and marketing practices of small farms. The objectives​ are to increase sorghum/millet crop yields, stabilize and increase prices with resulting higher incomes. ​

Diversification in the Cotton Zones of the Sahel​​​​

* Secondary markets are critical to reduce price flucations from good weather or rapid technological change. For millet this is the rapidly increasing sector of entrepreneurs producing processed millet food products. For sorghum, the feed grain sector will become more important with economic growth given sorghum's advantage over maize in drought tolerance and its lower soil fertility requirements.
