Smoke hoods save lives
In communities where people lack any access to grid electricity, wood and dung (biomass) is the main source of energy. ‘Clean’ fuel to cook food, light for study and power to run tools for earning a living is almost non-existent – and burning wood creates toxic smoke, which kills.
More than 3 billion people worldwide depend on fuel such as wood and coal for cooking and heating. Burning these fuels creates a dangerous cocktail of pollutants. It is the poor who rely on the lowest grades of fuel, and each year more than 4 million people die from in haling lethal smoke from kitchen stoves and fires.
But solutions are available. By working with women battling the extreme problem of indoor air pollution in their homes, Practical Action has developed a simple smoke hood, which reduces indoor smoke levels by up to 80%.
Working with communities in the developing world, Practical Action created a special smoke hood which is simple, cost effective and efficient, and is already helping to save lives.
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 - allowing more time for other activities.
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.
Increasing the impact
Indoor smoke is a killer. But we have simple solutions that can stop it.
We are extending our work to reduce indoor air pollution in Nepal. With your help, we can build more smoke hoods and improved stoves.
A simple technology makes a difference
In the Rasuwa district of Nepal, Practical Action has been helping families eradicate indoor smoke.
Life is hard for Sonam and Nima. Sonam works in his 16 ropani (about 2 acres) of land all day and Nima works round the clock cooking and taking care of their children and cattle. Their kitchen is also their bedroom – a refuge for indoor smoke.
Nima’s kitchen is poorly ventilated and the indoor smoke caused Nima’s health to ail. Due to improper combustion, she tired easily and complained of chest pains, headaches and eye irritation.
Sonam on the other hand could not understand his wife's complaints and had not paid much attention to his wife’s deteriorating health. “I talked to my friend, Bhume Lama, about my problems who happened to be a smoke hood manufacturer promoted by Practical Action. After listening to my problems and considering the fact that our kitchen is also our bedroom he advised me to install a smoke hood,” he says.
He talked to his wife about the benefits of smoke hood and agreed to install it but the cost of installation would amount to NRs. 5,000. “I had to install it for the benefit of my family,” he says. “I paid NRs. 1,000 as a down payment and obtained NRs. 4,000 as a loan from the village revolving fund." He pays NRs. 150 per month to the revolving fund to repay his loan.
After installation of the smoke hood Nima already feels the difference. Her eyes no longer waters and she no longer has headaches or chest pains. She spends more time outdoors as the cooking time has decreased significantly due to stove improvement leading to efficiency.
Sonam recently formed a group of 20 households to share his knowledge and experiences. Practical Action provided seed money to start a village revolving fund for the sole purpose of smoke hood installation. All the members from Sonam’s group have installed smoke hoods in their homes. “People now come to me seeking information on IAP and smoke hood, I am happy to share my knowledge and experience with them,” he says.
Video: Indoor air pollution - the biggest child killer in Nepal
In Nepal, indoor air pollution results causes the premature death of over 22,000 people annually *. In this video, see the effects of smoke in the home - and the impact of some practical solutions.
The killer in Mika's home
Mika is just 7 months old, and is battling pneumonia. Living with her family in the bitterly cold foothills of the Himalaya mountains, they are unaware that the fire they rely on to keep warm, cook food and give light, is also filling Mika's little lungs with deadly smoke.
Every minute of every day indoor smoke takes the life of a child like Mika. Thousands of families in Nepal are forced to put the lives of their children at risk as they so desperately depend on their fires to survive. But without a fire, the outcome for children like Mika would be just as bleak.
But you could help to save the lives of children like Mika and give them back their futures with a very simple solution.
With your help, we can build more smoke hoods and improved stoves.
