Improved Stoves and Other Measures
The World Health Organization has documented the significant number of deaths caused by smoke from home fires. The negative impacts can be reduced by using improved cook stoves, improved fuels (e.g. biogas, or kerosene instead of dung), changes to the environment (e.g. use of a chimney), and changes to user behaviour (e.g. drying fuel wood before use, using a lid during cooking)." Improved stoves are more efficient, meaning that the stove's users spend less time gathering wood or other fuels, suffer less emphysema and other lung diseases prevalent in smoke-filled homes, while reducing deforestation and air pollution.
For instance, an improvement of the energy efficiency from 25% for the traditional Lao stove (wood and charcoal fired) to 29% efficiency for an improved Lao stove, results in 21% less wood fuel being needed, and saves 182000 ton CO2eq emissions, as reported in this GHG-compensation project. The traditional Lao stove needs an average of 385 kilograms of charcoal and 450 kilograms of wood per year as fuel. For making a kilogram of charcoal about seven kilograms of wood is needed. The report also indicates that in Cambodia 369000 ton of non-renewable biomass wood fuel is consumed yearly for charcoal production for these stoves, destroying 45 km² of deciduous forests. This is not sustainable, as only 4% of the forests regrows.
Some designs also make the stove safer, preventing burns that often occur when children stumble into open fires. Some of the new stove designs are discussed below.

Famous quotes containing the words improved, stoves and/or measures:
“The liberal wing of the feminist movement may have improved the lives of its middle- and upper-class constituency—indeed, 1992 was the Year of the White Middle Class Woman—but since the leadership of this faction of the feminist movement has singled out black men as the meta-enemy of women, these women represent one of the most serious threats to black male well-being since the Klan.”
—Ishmael Reed (b. 1938)
“We do not suspect how much our chimneys have concealed; and now air-tight stoves have come to conceal all the rest.”
—Henry David Thoreau (1817–1862)
“However much we may differ in the choice of the measures which should guide the administration of the government, there can be but little doubt in the minds of those who are really friendly to the republican features of our system that one of its most important securities consists in the separation of the legislative and executive powers at the same time that each is acknowledged to be supreme, in the will of the people constitutionally expressed.”
—Andrew Jackson (1767–1845)
