Abstract: | Improved wood-burning stoves offer a possible solution that can simultaneously impact both problems of deforestation and problems
of respiratory health in developing countries. We carried out a field experiment in which new fuel-efficient woodstoves were
allocated in a Guatemalan village via the use of a lottery. A 2008 baseline survey was carried out on 2,148 individuals in
351 households, and then a follow-up survey was carried out in 2009, 4 months after households received the stoves. We found
that households with the new stoves reduced wood consumption by an average of 59.1%. We also found indications of reductions
in indoor air related health problems, where point estimates indicate a significant reduction in reported respiratory symptoms
by 48.6% among women and 63.3% among children. |
