This book of case studies represents a collaborative effort to explore the potential of biofuels to provide sustainable livelihoods and local sources of energy for people in rural areas of developing countries, with a special emphasis on women. Although there are many forms of bio-energy that can be useful in this regard, book focuses on plant products, mostly seeds, used to produce oil - which is then either utilized directly in engines or equipment, or processed into biodiesel. The book was presented at the 17th session of the UN Commission for Sustainable Development.
