Abstract
This study examined measures of clean cookstove adoption after improved solid fuel stove programmes in three geographically and culturally diverse rural Andean settings and explored factors associated with these measures. A questionnaire was administered to 1200 households on stove use and cooking behaviours including previously defined factors associated with clean cookstove adoption. Logistic multivariable regressions with 16 pre-specified explanatory variables were performed for three outcomes; (1) daily improved solid fuel stove use, (2) use of liquefied petroleum gas stove and (3) traditional stove displacement. Eighty-seven percent of households reported daily improved solid fuel stove use, 51% liquefied petroleum gas stove use and 66% no longer used the traditional cookstove. Variables associated with one or more of the three outcomes are: education, age and civil status of the reporting female, household wealth and size, region, encounters of problems with the improved solid fuel stove, knowledge of somebody able to build an improved solid fuel stove, whether stove parts are obtainable in the community, and subsidy schemes. We conclude that to be successful, improved solid fuel stove programmes need to consider (1) existing household characteristics, (2) the household’s need for ready access to maintenance and repair, and (3) improved knowledge at the community level.
Highlights
Three billion people continue to use solid fuels for cooking, heating and lighting [1].Exposure to solid fuel smoke often through the use of traditional cookstoves (“traditional cookstove”includes open indoor fire in this article) is associated with adverse health impacts like respiratory infections [2,3], ischemic heart disease [4], stroke [5], lung cancer [6], and cataract formation [5,7].Household air pollution was ranked the eighth leading health risk factor and was associated with nearly three million deaths in 2015 [8]
These variables were chosen based on a review of the literature and included (i) demographics and household variables (region, age, education and civil status of reporting female, household size, household wealth index, land ownership), (ii) knowledge and awareness variables, (iii) price and costing variables, (iv) stove design variables, variables describing the supply chain, the clean cookstove market and an enabling environment
In the Peruvian Andes the transition to clean cookstoves appears to be in process after many years of improved solid fuel stove (IS) and more recent liquefied petroleum gas (LPG) stove promotion
Summary
Three billion people continue to use solid fuels for cooking, heating and lighting [1].Exposure to solid fuel smoke often through the use of traditional cookstoves (“traditional cookstove”includes open indoor fire in this article) is associated with adverse health impacts like respiratory infections [2,3], ischemic heart disease [4], stroke [5], lung cancer [6], and cataract formation [5,7].Household air pollution was ranked the eighth leading health risk factor and was associated with nearly three million deaths in 2015 [8]. Three billion people continue to use solid fuels for cooking, heating and lighting [1]. Exposure to solid fuel smoke often through the use of traditional cookstoves Household air pollution was ranked the eighth leading health risk factor and was associated with nearly three million deaths in 2015 [8]. The use of traditional cookstoves has been shown to lead to negative social and environmental impacts through excess time and money spent [9], contribution to outdoor air pollution [10,11], deforestation and climate change [12]. To mitigate the negative impacts of burning solid fuels for cooking, efforts to promote the adoption of clean cookstoves are undertaken.
