Improved cook stoves (ICS) particularly mud-brick ICS with and without chimney is one of the most simple, inexpensive and widely used technologies designed to improve combustion efficiency of biomass and reduce exposure to indoor air pollution.
The benefits of ICS includes: increased thermal efficiency, conservation of forests by reducing fuel wood consumption, reduction in womens' drudgery, reduction in indoor air pollution and hence smoke-related health disorders, and prevention of fire hazards.
Traditional stoves used in Nepal are simple structures made from clay or having stone or metal tripods. These stoves are very ineﬃcient because they have poor air flow and insulation. As a result, they consume a lot of biomass and produce high levels of indoor air pollution.
ICS was introduced in Nepal in 1950s and continues to be relevant in the present context. AEPC/NRREP, together with other government, non-government and private organisations, is involved in developing and promoting diﬀerent types of ICS in Nepal and so far more than 700,000 improved cook stoves have been installed in 63 districts
