The World Health Organization (WHO) estimates that exposure to
smoke from the simple act of cooking is the fifth worst risk factor for disease
in developing countries, and causes almost two million premature deaths per year
– exceeding deaths attributable to malaria or tuberculosis.
Women in developing countries are also at risk of head and spinal injuries,
pregnancy complications, and maternal mortality from the strenuous task of
carrying heavy loads of firewood or other fuels. Frequent exposure to cookstove
smoke can also cause disabling health impacts like cataracts, which affect women
more than men, and is the leading cause of blindness in developing countries.
Rudimentary wood-fired cookstoves and open fires emit fine particles, carbon
monoxide, and other pollutants at levels up to 100 times higher than the
recommended limits set by WHO
A randomized-control study in Guatemala led by the University of California,
Berkeley, found that halving exposure to indoor air pollution with a chimney
stove brought about a reduction in severe pneumonia, and that larger reductions
in exposure had more pronounced effects. A systematic review of all available
studies on the link between solid fuel use and child pneumonia has found an
almost doubling of risk for those exposed.
Burns from open fires and unsafe cookstoves are another insidious risk faced by
poor households dependent on kerosene, open fires, and unstable metal or clay
cookstoves, contributing to a substantial percentage of the estimated 300,000
burn deaths that occur annually
While the link between exposure to cookstove smoke and a wide range of health
problems such as pneumonia, chronic obstructive pulmonary disease, and lung
cancer is well established, the current body of evidence linking cookstoves with
other potentially important health effects is compelling but less documented
Nearly all of the existing evidence is based on observational studies that
compare groups using open fires and traditional cookstoves with those using
cleaner fuels, with very little being directly obtained from studies that
directly measure the effects of interventions.
More evidence is needed to demonstrate that the levels of exposure reduction
delivered by clean cookstove and fuels will result in declines in related
illnesses and deaths.
