ABSTRACTApproximately 2.8 billion people rely on polluting cooking fuels (e.g. wood, kerosene), exposing them to health-damaging household air pollution. A key access barrier to clean cooking fuels (e.g. liquefied petroleum gas (LPG)) is affordability. By enabling households to pay in small increments, pay-as-you-go (PAYG) LPG could help promote clean cooking, and support continued LPG use through periods of economic downturn. We investigate the ability of PAYG LPG to sustain access to clean cooking from January 2018-June 2020, including during COVID-19 lockdown (March-June 2020) in an informal settlement in Nairobi, Kenya. We utilize novel PAYG LPG smart meter data to document cooking/spending patterns from 426 PAYG LPG customers and semi-structured interviews among a subset of seven households. Objective cooking pattern comparisons are made to those cooking with full 6kg cylinder LPG and polluting fuel users from 23 households in peri-urban Eldoret in western Kenya, using stove monitoring data. Customers’ average PAYG LPG consumption was 0.97 kg/capita/month (11.6 kg/capita/year) prior to COVID-19 lockdown. Despite adverse economic impacts of the lockdown, 95% of households continued using PAYG LPG, and consumption increased to 1.22 kg/capita/month (March-June 2020). Daily cooking events using PAYG LPG increased by 60% (1.07 events/day (pre-lockdown) to 1.72 events/day (lockdown)). In contrast, among seven households purchasing full 6kg cylinder LPG in Eldoret, average days/month using LPG declined by 75% (17 to four days) during COVID-19 lockdown. Median PAYG LPG payment frequency doubled (from every 8 days to every 4 days) during lockdown, while average payment amount was nearly halved (336 Kenyan Shillings (KSh)/US$3.08 to 179 KSh/US$1.64).Interviewed customers reported numerous benefits of PAYG LPG beyond fuel affordability, including safety, time savings, cylinder delivery and user-friendliness. PAYG LPG helped sustain clean cooking during COVID-19 lockdown, possibly averting increases in polluting cooking fuel use and associated household air pollution exposures.Graphical AbstractHighlightsFirst study to report long-term cooking/spending patterns using PAYG LPG smart meter data95% of 301 active PAYG LPG customers in February 2020 continued to use the fuel during COVID-19 lockdownDaily cooking events using PAYG LPG increased by 60% during COVID-19 lockdownMedian payment frequency increased 50%, while single payment amount decreased 50% during lockdownThree-quarters of PAYG LPG households in this study were first time LPG users

Cooking Fuels

Background Household air pollution adversely affects human health and the environment, yet more than 40% of the world still depends on solid cooking fuels. The House Air Pollution Intervention Network (HAPIN) randomized controlled trial is assessing the health effects of a liquefied petroleum gas (LPG) stove and 18-month supply of free fuel in 3,200 households in rural Guatemala, India, Peru, and Rwanda. Aims We conducted formative research in Guatemala to create visual messages that support the sustained, exclusive use of LPG in HAPIN intervention households. Method We conducted ethnographic research, including direct observation ( n = 36), in-depth ( n = 18), and semistructured ( n = 6) interviews, and 24 focus group discussions ( n = 96) to understand participants’ experience with LPG. Sixty participants were selected from a pilot study of LPG stove and 2-months of free fuel to assess the acceptability and use of LPG. Emergent themes were used to create visual messages based on observations and interviews in 40 households; messages were tested and revised in focus group discussions with 20 households. Results We identified 50 codes related to household air pollution and stoves; these were reduced into 24 themes relevant to LPG stoves, prioritizing 12 for calendars. Messages addressed fear and reluctance to use LPG; preference of wood stoves for cooking traditional foods; sustainability and accessibility of fuel; association between health outcomes and household air pollution; and the need for inspirational and aspirational messages. Discussion We created a flip chart and calendar illustrating themes to promote exclusive LPG use in HAPIN intervention households.

Abstract Background: Household air pollution (HAP) is a recognised risk factor for many diseases, including respiratory diseases, cardiovascular/circulatory disorders, adverse pregnancy outcomes and cataracts. Population exposure to biomass fuels, including wood, varies among countries and from one fuel source to the other. This study aimed to investigate the different sources of HAP in peri-urban and rural communities in Cameroon. Methods: A cross-sectional survey was conducted in a representative sample of households from the Dschang Health District (DHD) region. This included 848 homes in which a range of fuels for cooking including biomass (firewood, charcoal, sawdust), kerosene and liquefied petroleum gas (LPG) were used both indoors and outdoors. Results: Of the study households, 651 (77%) reported exclusive use of firewood and 141 (17%) reported using more than one source of fuel. Exclusive use of firewood was greater in rural communities (94%) than in peri-urban communities (38%). In peri-urban communites, use of multiple fuels including LPG, wood, sawdust and kerosene, was more common (44.75%). A total of 25.03% of households in both peri-urban and rural communities reported using bottled gas (or liquified petroleum gas (LPG) for cooking. Motivations for choice of fuel included, price, availability (easy access), rapidity, tradition or culture related factorsConclusion: Wood is the main cooking fuel in both peri-urban and rural communities in the Dschang Health District. Work to help households (especially those who are resource poor) to adopt LPG equipment for cooking, and use in a more exclusive way is required.

The Impact

Background: Exposure to PM2.5 arising from solid fuel combustion is estimated to result in approximately 2.3 million premature deaths and 90 million lost disability-adjusted life years annually. 'Clean' cooking interventions attempting to mitigate this burden have had limited success in reducing exposures to levels that may yield improved health outcomes. Objectives: This paper reports exposure reductions achieved by a liquified petroleum gas (LPG) stove and fuel intervention for pregnant mothers in the Household Air Pollution Intervention Network (HAPIN) randomized controlled trial. Methods: The HAPIN trial included 3195 households primarily using biomass for cooking in Guatemala, India, Peru, and Rwanda. 24-hour exposures to PM2.5, carbon monoxide (CO), and black carbon (BC) were measured for pregnant women once before randomization into control (n=1605) and LPG arms (n=1590) and twice thereafter (aligned with trimester). Changes in exposure were estimated by directly comparing exposures between intervention and control arms and by using linear mixed-effect models to estimate the impact of the intervention on exposure levels. Results: Median exposures of PM2.5, BC, and CO post-randomization in the intervention arm were lower by 66% (70.7 versus 24.0 µg/m3), 71% (9.6 versus 2.8 µg/m3), and 83% (1.2 versus 0.2 ppm), respectively, compared to the control arm. Exposure reductions were similar across research locations. Post-intervention PM2.5 exposures in the intervention arm were at the lower end of what has been reported for LPG and other clean fuel interventions, with 69% of PM2.5 samples falling below the WHO Annual Interim Target 1 of 35 µg/m3. Discussion: This study indicates that an LPG intervention with high displacement of traditional cooking can reduce exposures to levels thought to be associated with health benefits. Success in reducing exposures was likely due to strong performance of, and high adherence to the intervention.

Introduction: Despite program efforts to encourage use of clean cookstoves and fuels to mitigate climate change, many communities continue to use wood-fueled open fires. Objectives: Describe experiences of participants with mixed use of cooking and fuel technologies (e.g. open fires and chimney stoves using wood and liquefied petroleum gas (LPG) stoves) in rural Lambayeque, Peru in 2018. Material and methods: Fifteen participants were interviewed using a qualitative exploratory research design. Data was collected through semi-structured interviews and analyzed using thematic content analysis. Results: Four categories emerged: decisions about acquiring cooking fuels are primarily based on cost; plastic trash is used to light wood-burning stoves; decisions to use gas over wood are based on quick food cooking time; and benefits and health problems are recognized, but mixed use of fuels persist. Conclusion: Use of both traditional wood cookstoves and plastic trash to ignite fires were used frequently because both are free or cheap. The environmental impact of cutting down trees isn't considered important, but interviewees did notice detriments to their wellbeing. Although gas stoves are used and benefits were mentioned, use of traditional stoves persists. We recommend that policy makers in Peru begin to address barriers to full adoption of new clean cooking technologies and consider governmental subsidies to meet families' spending priorities.
