The study examines the benefits of biogas adoption in Nepal using survey data, land satellite images and GIS mapping tools. The study shows from the women's standpoint how biogas has brought many benefits to local women and the environment. The findings suggest that installing biogas plants saves time for women and improves their respiratory health. It is also concluded that the saved time has not been effectively used. Biogas is also found to be the reason for increased revenues for the community, and replacing 2.7 to 5.3 tonnes of fuel wood annually with an increase in a forest area of 135 hectares. Two major challenges to the sustainability of these benefits related to health, well-being, environment and community are discussed, along with some suggestions for addressing them.
