The value of community technology workers for LPG use: A pilot in Shirati, Tanzania

Background: Sustainable Development Goal (SDG) 7 calls for the adoption and continued use of clean-burning stoves by the 2.9 billion people relying on unclean fuels (both solid biomass and kerosene). However, to date, the clean cooking literature has found low rates of efficient stove adoption and continued use. This paper presents the application of a public health community engagement model to the use of clean cooking fuels. We implemented a pilot study with Community Technology Workers (CTWs) as a means to overcome maintenance, education, and behavioral barriers to clean fuel use in rural Tanzania. Methods: The intervention was a free 6 kg Liquified Petroleum Gas (LPG) cylinder and stove coupled with education from a local technically trained CTW on LPG use. We evaluated the training, work, and impact of a CTW on LPG use on 30 randomly selected households from two villages in a rural district of Tanzania over a 1-year period. After an initial baseline survey, technically trained local CTWs educated the households on safe LPG use and conducted 34 follow up surveys over the next year on their cooking fuel use. Additionally, we conducted qualitative interviews with all households and a focus group with six of the households. Results: The results from the mixed methods approach show that 80% of families (n = 24) consistently refilled their LPG cylinders and similar to 40% of households exclusively used LPG. Households reported appreciating the CTWs' visits for providing education and maintenance support, giving them confidence to use LPG safely, reminding them to save for their cylinder, and providing a community driven effort to use clean fuel. Conclusions: The findings demonstrate the feasibility of this type of community infrastructure model to promote and facilitate consistent LPG use, but suggest the need to couple this local support with financial mechanisms (e.g., a microsavings program). This model could be a mechanism to increase LPG use, particularly in rural, low-income areas.

Automated summary

This study applies a public health community engagement model to promote the use of clean cooking fuels in rural Tanzania. The intervention provided free LPG cylinders and education on LPG use by local Community Technology Workers (CTWs). The results show that 80% of families consistently refilled their LPG cylinders and about 40% of households exclusively used LPG. The findings highlight the feasibility of this community infrastructure model and suggest the need for financial mechanisms to further support LPG use.
