This manual was initially designed to help school feeding programs use cleaner and more efficient cooking stoves by reducing smoke emissions and fuel wood consumption. Then, we realized that its contents could also be adapted and used in other set- tings. We encourage anyone interested in improving their cooking stoves to use this manual. The book teaches how to design and develop better cooking stoves, train local stove producers, and cooks how to use and maintain improved stoves. Teachers can use this manual to educate their students about the importance of reducing indoor air pollution and alleviating the negative social and environmental impacts of fuel wood consumption. Most importantly, they can teach students how to apply these recommendations in their every day lives.
