From Scientific American:
The world will be able to feed the predicted 2050 population of nine billion people, according to two French agricultural research organizations. In a joint report published today, they lay out findings gleaned from 2006 to 2008 that could overturn some current assumptions about the state of global farming.
The report, titled Agrimonde1, is published by the French National Institute for Agricultural Research (INRA) and the Centre for International Cooperation in Agronomic Research for Development (CIRAD), both headquartered in Paris. It contains some surprise findings on Africa and other regions -- the latest results from an ongoing study by the two research agencies.
