Patterns of fuel use, cooking practices and factors associated with the use of LPG for cooking in peri-urban Cameroon

Abstract

Background/Aim: Over three billion people, mostly living in low and middle income countries (LMICs), are exposed to household air pollution from reliance on polluting fuels (e.g. wood, charcoal). There is a dearth of information on barriers to adoption and sustained use of clean cooking fuels, (e.g. liquefied petroleum gas (LPG)) in remote locations in sub-Saharan Africa. Methods: A cross-sectional demographic and fuel use survey was completed by approximately 1500 household cooks from peri-urban Mbalmayo in Central Cameroon. Stratified random sampling was conducted to identify approximately 200 clean (LPG) and 200 polluting (e.g. wood) cooking fuel users who completed in-depth surveys on individual and household characteristics that were potentially associated with cooking behavior and fuel choice. Results: Among households using solid fuels (n=196), the main reported barrier to LPG adoption included the initial cost of LPG equipment (n=87; 59%). Concerns over LPG safety were a significant concern in both users and non-users of LPG (n=366; 83.6% perceived LPG to be dangerous). Decision making over choice of cooking fuel was approximately equally split between the main cook (typically women) and the head of household (usually men); men were in charge of decision making regarding cooking fuel adoption among 41.4% (n=121) LPG users and 56.2% (n=82) of biomass users. Stacking was universal (100%) amongst LPG users, with 70% LPG use. Free secondary fuel and a distance 20-30minutes from retail point reduced LPG use by 20% and 10% respectively. Household head unemployed (O.R 2,057, p-value .000), No formal education (O.R 15.200,p-value .006), and Cost (O.R 2.489, p-value 0.000) were all associated with the non-adoption of LPG. Conclusions: Addressing safety concerns through education, and financially supporting households (e.g. through microfinance) will considerably scale LPG adoption in peri-urban Cameroon. Policies to facilitate LPG adoption should be targeted to both genders. Key words: LPG, clean cooking, adoption
