Abstract

Background: Indoor air pollution, primarily emitted by burning solid fuels indoors in poorly ventilated conditions, is one of the greatest agitators of respiratory infection worldwide. In the Democratic Republic of Congo (DRC) indoor air pollution, linked to respiratory infection, is responsible for 19% of child deaths under five, outranking malaria and diarrhea as the top contributor to child mortality. One proposed solution to reducing the ill health effects of indoor air pollution is to promote improved clean cookstoves.

Objective: The primary objective of this study was to understand household experience with the Top-Lit Up Draft (TLUD) clean cookstove. Secondary objectives were to determine possible barriers and incentives to households' using and liking the stove, and finally to investigate households' willingness to pay for the stove.

Methods: A mixed methods sequential design study was used to examine household experience with the stove. Forty households in Mokali, Kinshasa, were randomly selected to receive the TLUD stove. One month after receiving the stove, five focus group discussions were conducted with household members that had used the stove. A month later, a survey was administered to the 40 households that received the TLUD stove. Survey questions were informed by data from the focus group discussions.

Results: Results of the study show that household experience with the TLUD stove was dependent upon the fuel market environment, the cost of fueling the TLUD stove, smoke, and design elements of the stove. The biggest barrier to having a positive experience with the stove centered around the kind of wood households used to fuel the stove. Willingness to pay for the stove, regardless of experience, was low.

Conclusion: The complex relationships of factors affecting stove experience and likelihood of adoption point to the necessity of understanding the context of household energy and fuel environments as well as household preferences. Household willingness to adopt clean cookstove technology extends far beyond the economics of fueling and purchasing, but also involves greater social, economic, and technological factors.
