Human and environmental health costs and benefits of firewood versus clean fossil fuel use by Forcibly Displaced Myanmar Nationals and host communities in Bangladesh

What did the study set out to achieve?

The study aimed to add to the limited evidence base on the adoption of liquified petroleum gas (LPG) and implementation of an LPG delivery system in a humanitarian context. It specifically aimed to investigate the health and environmental impacts of the distribution of LPG to replace firewood for cooking in Rohingya refugee camps. It also aimed to investigate the intervention’s cost-effectiveness and how the effectiveness of LPG distribution and uptake could be increased.

A cross-sectional study was conducted of communities that are and are not receiving free propane distribution. By studying the factors that influence household’s usage of propane and firewood, the research sought to better understand how these factors affect health, household economics, and the environment. Often these factors have particularly negative impacts on women and children.

What were the key findings?

The LPG distribution programme was associated with high exclusive use of LPG. It also:

•  replaced 4.3 kg of firewood/day with 0.34 kg of LPG/day, preventing 330,600 tons of firewood extraction and 407,000 tons of CO2 emissions;
• increased spending on food (from $7.19/month to $8.55/month);
• reduced air pollution, preventing 2,309 adult deaths and 385 child death over 5 years;
• lowered the prevalence of female caregivers at risk of depression by 10.0%;
• reduced the prevalence of burning of plastic as a cooking fuel from 40% burning 5+ days/week to 0%; and
• reduced inter-group and domestic violence.

The programme cost $0.34-$0.47 per day per family. Since refugees needed to bring their cylinders to the depot to collect the LPG refill, targeting of resource appeared effective: very few LPG tanks were “lost” and needed to be replaced.

What are the implications for humanitarian practitioners and policymakers?

Humanitarians can use the results of this study to help donors understand the multi-sectoral impact of their funding: not only does funding the provision of clean-cooking reduce respiratory illness and save lives, but it also improves food security and reduces refugee-host conflict and domestic violence.

Humanitarians could advance clean cooking for refugees by:

• assessing sustainable clean fuel options for other humanitarian settings;
• continuing to develop technologies and processes the increase the efficient use of cooking fuel;
• developing international financing mechanisms; based on carbon credits or results-based tools to
  offset the cost of fuel provision, and;
• considering incorporation of fuel provision into the mandate of the World Food Program (WFP).

Donors can draw on these study results to be reassured that their contributions to a clean cooking fuel programme provides a range of benefits well-targeted to refugee beneficiaries.
