The case for fuel-efficient stoves is strong. In most societies, women are in charge of cooking, spending between three and seven hours per day near the stove, depending on the demands of the local cuisine. According to the World Health Organization, 59 percent of all indoor air pollution related deaths are female. There is also a strong risk to young children who spend a large proportion of their time close to their mother, breathing in smoke from cooking fires during their early developing years.
In addition to the health burden, there are also livelihood and environmental consequences resulting from the use of open fires. The use of improved fuel-efficient stoves can reduce the production of smoke and harmful gasses within households, reduce the use of biomass by up to 60 percent (wood, crop waste, dung etc), reduce cooking cycle times, and create significant household safety and labour benefits. The use of biomass for daily fuel consumption in developing countries accounts for up to 90 percent of all energy use and the majority of this is from non-renewable sources.
