The Ranthambhore National Park in Rajasthan, India, is the home of the endangered Indian tiger, and the demand for fuelwood for cooking in surrounding villages puts great pressure on the park's trees. The Prakratik Society has installed 250 biogas digesters in villages on the park's fringes. The digesters use cattle manure to produce biogas for cooking, and thus save fuelwood.
