Small ceramic indoor stoves, such as those sold by women in AIDS self-help groups in Africa, do save fuel and cut down on eye-irritating smoke, a new study has found — but they do not save children from pneumonia.
The study, published in The American Journal of Tropical Medicine and Hygiene, compared 168 households in rural Kenya that used either “upesi jiko” stoves or traditional three-stone indoor fires. The former — the name means “quick stove” in Swahili — has a locally made ceramic firebox that sells for $3. Clay and mud must be built up around it to insulate it and support the pot.
Since it uses less wood, it saves local forests. But it has no chimney, so the smoke stays indoors.
Biweekly visits by researchers found that children in both the stove and open-fire homes got pneumonia equally often. Pneumonia is a leading cause of death for infants in poor countries, and a 2008 study showed that the fine particles and toxic gases in cooking smoke inflame their lungs, doubling the pneumonia risk.
Two years ago, Secretary of State Hillary Rodham Clinton committed $50 million in American aid to help the Global Alliance for Clean Cookstoves get 100 million efficient stoves into households by 2020. But experts are still divided over which stove to pursue; chimneys do not solve all the problems, and stoves with fans burn more cleanly but are expensive and fragile.
