Sustainable development has been one of Development Marketplace's themes since its beginning 10 years ago. It's hard to count all the DM winners and finalists who have come forward with innovative "green" ideas that they wanted to share. Just a few examples:
One of the winners in DM2007 -- themed "Health, Nutrition, Population" -- was a Massachusetts Institute of Technology-sponsored project to develop clean-burning cooking charcoal from agricultural waste. Haiti's traditional cooking fuel often comes from wood. But wood burning produces high pollution that is a cause of widespread respiratory disease. Substituting charcoal for cooking not only improves the health of Haitian families, but also means fewer trees -- a major protection against soil erosion -- are cut down.
