Reducing indoor air pollution in Nepal
In rural areas across Nepal, traditional stoves are common. Simple three-stone stoves cook food for the family and heat the home during the cold winter months – but they also fill the home with thick black smoke.
This smoke fills the lungs of the whole family, causing them to cough and their eyes to stream – and potentially causing serious or fatal illnesses such as stroke, heart disease and cancer. But there is a solution. An improved stove with smoke-hood will improve the health of families across Nepal.
What we’re doing to help
Objective: Improving the health and livelihoods of women and their families by providing access to fuel-efficient stoves and smoke hoods,
Project name: Result-Based Financing for Sustainable Hood-Stove Market
Location: Gorkha, Dhading, Makwanpur, Rasuwa and Nuwakot districts, Nepal
Project date: June 2014 - July 2018
Partners: GORETO in Gorkha; Multi-Dimensional Resource Centre (MRC-Nepal) in Makwanpur; Indoor Smoke Alleviation and Environment Protection Forum Nepal ( ISAEPF-Nepal) in Rasuwa; and Forum for Community Upliftment System (FOCUS Nepal) in Dhading.
This project will help families get a complete package of a specifically designed smoke-hood and improved stove running off locally-available ‘biomass’ – firewood, crop residue or animal dung.
The improved stoves use the smoke-hoods to draw smoke up and away from the home, reducing indoor smoke by 80%.
As well as improving the health of all the family, the stoves use less fuel. They’re cheaper to run, but they can also give women their time back. When they no longer have to to spend time searching for wood and carrying heavy loads back home, women can learn new skills, spend good quality time with their children and earn an income.
Indoor air pollution is a huge problem, but it needn’t be. This project will help many people and make sure they no longer have to risk the health of their family just to cook a meal.
Findings from a new study into the effects of improved stoves in Malawi suggest that improved stoves do not reduce occurrences of pneumonia in children under 5, as the World Health Organisation and others assert. Read a response from Dr Lucy Stevens, our energy access and clean cooking policy lead, including how this new study relates to our on-going work to stop the #killerinthekitchen.
Look how far your money can go
“The doctor used to tell us not to sit in front of the fire because of the smoke, but we had no choice. Now with the smokehood it is clear, I can see things. The smoke doesn’t spread over the room. It uses less firewood and we can dry meat easily.” – Lal Singh Bal, Nepal
Smoke-hoods change lives
People have been cooking and heating their homes in the traditional way in Nepal for centuries, so some people are resistant to change, not believing that smoke is to blame for their health problems. We will be educating people about the dangers of indoor air pollution and why a smokehood and improved cook stove is so important.
We are working mainly with poor families in rural Nepal. With the availability of subsidies and low-interest micro-loans through local cooperatives, even the very poor households will be able to access the technology.
It's important to create a long-term, sustainable and viable industry and market that can supply life-transforming smokehoods and clean stoves long after the project finishes. This industry cannot start on its own, so this project provides the capital upfront, subsidises and underwrites loans, and provides training. It also empowers communities that have never previously had formal access to financial institutions.
We also recognise that Practical Action cannot change the situation on its own. Instead projects like this demonstrate to local governments and other international institutions what solutions work and what challenges they are likely to face, to help bring about long-term change.
- Household air pollution reduced by more than 80%
- Improved respiratory and eye health of beneficiaries, mainly of women and children
- 50% reduction in firewood consumption compared with traditional stoves
- Time and money saved collecting or purchasing fuel wood is available to invest in personal development, education and earning an income – an average of 360 hours per year per family
The empowerment of women through female-led cooperatives and cook-stove enterprises, and an increased involvement in cook-stove markets
Read more about this project
The traditional stoves used in Nepal are simple structures made from clay, with stone or metal tripods. These stoves are very ineﬃcient because they have poor air flow and insulation, and as a result they consume a lot of fuel and produce high levels of indoor air pollution.
A combined improved stove with smoke hood tackles both of these problems in one design.
The sheet metal smoke hood sits over the fire, drawing smoke straight out through the roof.
As well as the health benefits of significantly cleaner air, a fire beneath a smoke hood burns more efficiently, so less fuel needs to be collected - typically 40% less.
As local conditions and available materials vary, we work with communities to determine the best design of smoke hood for their needs. Our Healthy Hoods toolkit, based on our experience in this field, can help other agencies to make similar choices.

Other technologies that can improve fuel efficiency and reduce air pollution
We have found throughout our work that one size doesn’t fit all, so we offer different solutions depending on local conditions.
In Darfur in western Sudan we have a similar financial model to Nepal, but use it to encourage people to swap traditional open fires for gas fires (because there is a large and cheap supply of liquid petroleum gas, a by-product of the oil industry in the region).
In Peru we have worked to improve the demand for portable stoves, and in East Africa, we have tended to focus on improved biomass stoves.
