"The Water Efficient Maize for Africa (WEMA) program  was launched in 2008 with a $47 million grant from mega-rich philanthropists Warren Buffet  and Bill Gates. The program is supposed to help farmers in several African countries increase their yields with drought- and heat-tolerant corn varieties, but a report released last month by the African Centre for Biosafety  claims WEMA is threatening Africa's food sovereignty and opening new markets
for agribusiness giants like Monsanto.
The Gates Foundation claims that biotechnology, GE crops and Western agricultural methods are needed to feed the world's growing population and programs like WEMA will help end poverty and hunger in the developing world. Critics say the foundation is using its billions to shape the global food agenda and the motivations behind WEMA were recently called into question when activists discovered  the Gates foundation had spent $27.6 million on 500,000 shares of Monsanto stock between April and June 2010."
