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, our focus in this book is on plant products, mostly seeds, used to produce oil – which is then either utilized directly in engines or equipment, or processed into biodiesel.
