In 2001 Ochsner founded ADES to help combat rampant deforestation. Ochsner lived in Madagascar in the early 1970s and was shocked, when she visited in the late 1990s, at the amount of deforestation that had occurred in a period of just 25 years. (Madagascan families use about 100 kilograms of charcoal on a monthly basis, amounting to one-sixth of an average monthly salary.) Ochsner researched cooking alternatives that would reduce firewood and charcoal use, and discovered solar cookers. Madagascar, especially in the south of the country, has close to ideal conditions for the use of solar energy.
