Clean cookstoves don’t just save lives; they add healthy years to someone’s life.
In November of last year, Trees, Water & People and our Nicaraguan partners, Proleña, partnered with Aprovecho Research Center to compare the emissions from open-fire stoves to those from Proleña’s improved stoves, manufactured in Managua. The results were alarming, which is why we are raising $8,000 to provide 60 clean cookstoves to those 60 study participants still cooking over open fires.
This study took place near Jinotega, Nicaragua with half of the families using traditional open fire stoves, and the other half using Proleña’s clean cookstoves. Each stove user volunteered to wear a small monitoring device that attaches to the shirt near the woman’s face to approximate her exposure to smoke for a 24-hour period. These monitors collect small airborne particles, referred to as PM2.5 in the air quality monitoring field, that are the most commonly measured pollutant coming from wood smoke. PM2.5 particles are widely accepted as a principle source of illnesses like chronic obstructive pulmonary disease, lower respiratory infections, lung cancer, and cardiovascular disease.
The average traditional stove user in this study was consistently exposed to 245 µg/m3 of particulates, qualifying their kitchens as a “HEAVY POLLUTED” environment, according to the EPA’s Air Quality Index. In homes where an improved stove had been introduced and adopted, exposure to indoor air pollution was reduced by an average of 63%.
Averted Disability Adjusted Life Years (ADALY) is a commonly used metric for public health studies that represent the number of years of healthy life made possible by reducing exposure to particulate matter in smoke. Using the ADALY methodology, we determined that if clean cookstoves were installed in 500 homes (helping 2,500 people), we could extend life in that population by 286 years. This is why we’ve launched the “Clean Cookstoves and Healthy Families in Nicaragua” campaign because, quite frankly, cooking shouldn’t kill!
Overall, this study was an excellent reminder that clean cookstoves are indeed critical, tangible tools that can help improve a person’s quality of life measurably. It is difficult to put a price on extra years of health, but with $8,000 we’ll be able to complete funding for 60 stoves needed in Jinotega.
Help thank the women in this study who opened their kitchens to us, and who are still breathing smoke as you read this. Give Health. Give Hope. Give Today!
Valentina de Rooy is a Nicaraguan psychologist with experience in qualitative research about social phenomena. Her passion is working with rural communities on a diversity of issues for the community development in Nicaragua, her country of origin. Valentina became familiar with Trees, Water & People’s work through Lucas Wolf, TWP’s former International Director, whose dedication to the people and the environment inspired to engage in TWP’s mission.
I recently had the opportunity to travel with Trees, Water & People’s nonprofit partner in Nicaragua, PROLEÑA, for a clean cookstove health study. The Aprovecho Research Center and PROLEÑA joined forces to carry out a study to measure the difference in pollution from smoke emissions in households cooking with wood in traditional stoves and improved stoves around Jinotega, Nicaragua. My role was to serve as interpreter and research assistant to Sam Bentson, the lab manager for Aprovecho.
For a month and a half, we stayed in Jinotega, a city located in northern Nicaragua in the dry corridor of Central America. Sam, some technicians of the NGO La Cuculmeca, and I visited more than 120 homes in six rural communities in the outskirts of the city of Jinotega. The participants in our study received us with great hospitality, stories, and gifts of crops they grew themselves. The children of the communities satiated their curiosity by following us to each of the households; some of them were even essential to the study by showing us the route to their neighbors’ homes.
We met so many amazing people during our stay. We met Don Aparicio, who has dedicated his life to the development of projects in his community of Saraguasca. While we were walking along the hill one day, Don Aparicio sang to us some verses composed by “Los Soñadores de Saraguasca,” a group of which he is a member and dedicates his songs to nature, its protection and conservation:
Let’s take care of the animals,
that enliven our environment,
like those found in the forest
over there at Agua Caliente.
For destroying our woodlands,
they had to be absent,
but if we reforest,
they will return.
In the last stage of the study, we met Doña Cata from the community of Las Lomas. Doña Cata and her husband Mario are pioneers in their community when it comes to crop diversification for their own consumption and they play a key role in hosting community meetings for the people engaged in agricultural projects.
Doña Cata introduced us to Idania, a young entrepreneur who runs her own cake-making business by modifying her PROLEÑA clean cookstove with two large pots in a small oven for baking cakes. Like most beneficiaries of improved stoves, Idania enthusiastically commented on her positive experience with smoke reduction and fuel saving. Now, the stakeholders are looking forward to the results of the study, hoping to know about their health condition in order to suggest changes for the future of their communities.
An update from TWP’s International Director, Gemara Gifford:
We are pleased to announce that each participant in this study who cooks with an open-fire cookstove will be receiving a brand new clean cookstove as a reward for participating in this study. For the first time, these families will be able to breathe easierand save time and money on fuelwood. Keep an eye out for how you can sponsor a family to make this a reality! If you would like to help fund the construction of these families’ clean cookstoves, please donate today!
As the holiday season begins in the United States, many of us gather with family to cook our favorite meals, celebrate with friends, to reflect back on the past year, and to make plans for the next. If we’re lucky, the holiday season creates a sense of comfort, community, and pride.
As TWP looks back on our year, one of our proudest moments has been working with you – our community – to help 500 more families in southern Guatemala begin their new year with a brand new clean cookstove. Last week, the final installment of stoves were delivered, and families are now being trained on its care and maintenance, just in time for the holidays! In March, some of you will be joining TWP Tours on our next tour to the region to see first-hand how families have been impacted by their new stove.
If you’ve been following us for a while, you know that clean cookstoves have a lasting impact on people’s lives because they:
reduce dangerous indoor air pollution by up to 85%
reduce forest fuelwood needed by up to 50%
are more efficient and thus save families valuable time and money
But perhaps the most inspiring and transformative impact of a stove is not in the numbers, but rather, within oneself. By listening to women across Central America for the last 19 years, we know that stoves:
increase women’s self-esteem and self-worth
create hope, pride, and dignity
help people thrive, not just survive
foster the ability to think “beyond tomorrow”
When I met Doña Teresa earlier this summer, she was thrilled to cook me something yummy on her new stove. She was proud to tell me how her day-to-day activities had been transformed. “My clothes look so much nicer now,” she said. “I don’t have soot all over them, and I am not embarrassed to invite my friends over anymore.” The best part was her smile. There are certain things that we simply cannot communicate with statistics – the pride in her face told me everything I needed to know. “And by the way, I don’t have to spend so much time cooking, this thing stays on all day, and the wood that I need is much less,” she said.
I am excited to visit Doña Teresa again on my next trip in January to see how she doing, and thank her for teaching me such a valuable lesson about what a stove represented to her!

Remember that parable about the boy and the starfish? It went something like this — a boy walked along the beach, picking up starfish and throwing them back into the ocean. A recent storm had passed, and the shore was covered with thousands of them. A man stopped and asked the boy what he was doing, pointing out that he couldn’t possibly help all the starfish. The boy bent down, picked up another one, threw it into the ocean, turned to the man and replied with a smile, “It made a difference to that one.”
Our research in environmental health can feel daunting. Around 2.8 billion people, almost a third of the world’s population, use solid fuel to meet their household energy needs, like cooking and heating (Bonjour et al., 2013). Using inefficient stoves to burn solid fuel — like wood, animal dung, and coal — creates toxic pollution. Imagine hovering over the thick plume of smoke from a campfire for hours a day. Now imagine doing that indoors for the majority of your life. The health impacts from breathing solid fuel smoke are many, such as lung cancer, pneumonia, poor pregnancy outcomes, and cardiovascular effects (Quansah et al., 2017). It is estimated that in 2015, 2.9 million people died prematurely due to their exposure to solid fuel smoke, mostly from cooking (Forouzanfar et al. 2016). In addition to the negative impacts on human health, these inefficient stoves create hazardous pollution for the environment and use resources, such as trees, for fuel.
With a problem this vast, it can be hard to imagine that one project among 230 women in rural Honduras would make a difference.
But we are making good on a promise that was made in 2014 to these women and their community leaders — to select a group of families to receive an improved Justa (pronounced ‘who-sta’) stove and visit them every six months for a few years to see how their pollution levels and health change after receiving a Justa clean cookstove. The Justa is a well-accepted, culturally appropriate stove, which was originally designed by Trees, Water & People, and is now made locally in Honduras. If you ask the women in our study, who had cooked their entire lives on traditional stoves and then received their Justa stove in 2016 or 2017, you’ll hear heartfelt stories of less smoke, less coughing, and cleaner air for the entire family.
Of course, it will be ideal at the end of the study if we see improvements in women’s health, like lower blood pressure, plus reductions in household air pollution and use of less wood-fuel.
Changes like these can have larger public health impacts and potentially lead to stove interventions among entire communities. However, regardless of the bigger picture from this study, I know that the 230 houses that were involved with this intervention are now cooking on cleaner and more efficient stoves, with less smoke inhaled by the entire family, and I feel confident that we have made a difference for those “ones.”
Trees, Water & People and our partner organization, Utz Che’, are working to build 500 clean cookstoves this year in Guatemala. If you would like to help fund a stove for a family or would like to learn more about the importance of this project, click the button below.

Several years ago, Marta Alicia Orellana of El Porvenir, El Salvador had invested in building a formal latrine at her home, but due to a lack of finances it was never finished. As the base and the walls deteriorated, she found herself using shower curtains around the latrine for privacy, but risked “exposing her physical and moral integrity” daily due to the poor state of her family’s bathroom.
When Trees, Water & People and the Mayor’s office of El Porvenir announced another round of latrine donations, she quickly put her name on the list. She now says she feels more secure having reduced risk of contamination for her family and for those who visit her home, and shows off her new latrine proudly.
How does a dry composting latrine work?
The dry compost latrines consist of two chambers made of concrete cinder blocks with a toilet seat, including urine diverter, placed over each of the chambers. After each use, stove ash, compost, and/or sawdust is added inside the chamber to reduce odors and keep the chamber dry. It also includes a vent to allow fresh air to circulate and further dry the solid matter. After one chamber is filled it is left to dry during six to eight month periods while the second chamber is in use. The contents of the first chamber are then transformed into a rich fertilizer that can be used on surrounding crops or trees after a drying period under the sun and mixed with a 1:1 ratio of earth. One dry composting latrine can serve families of more than six people for over 10 years with proper maintenance.
This region is tropical and volcanic, with regular seismic activity, episodes of torrential rains, and a high water table. During big rain events, the ground gets completely saturated, flooding traditional pit latrines, which then leach excrement and pathogens onto open land, into agricultural fields, and into drinking water supplies. Replacing these common pit latrines with composting latrines means cleaner groundwater and a more hygienic conditions in the home, leading to a lower disease burden in these communities.
A new report released by the World Health Organization (WHO) calls attention to the devastating effects of El Niño in Guatemala, Nicaragua, Honduras, and El Salvador. El Niño refers to the “large-scale ocean-atmosphere climate interaction linked to a periodic warming in sea surface temperatures across the central and east-central Equatorial Pacific (NOAA, 2016).”
El Niño Wreaks Havoc on Central America
The presence of El Niño has caused prolonged drought in Central America that is expected to last through at least March of 2016. Crop failure, especially in the “dry corridors” of Guatemala, Nicaragua, Honduras and El Salvador, has already affected 4.2 million people in the sub-region.
As with many climate-related events, the poorest households are most affected. Food insecurity and malnutrition are the biggest challenges facing these countries and are expected to last through the next harvest in August 2016. Guatemala and Honduras have gone as far as to declare a state of emergency. The governments of Nicaragua, Honduras and El Salvador are providing support to farmers by distributing seeds and water pumps.
Most farmers in the region, particularly subsistence or small-scale campesino (rural farmer) operations, rely predominantly on natural rainfall for their crops, and these recent weather patterns, caused by El Niño and increasing climate volatility, have exacerbated food insecurity and overall instability in the rural areas of Central America. We are not even halfway through the summer season here, with full bore temperatures (and corresponding dryness) reaching its peak in the months of March and April.
Eco-Friendly Agriculture in a Changing Climate
One of the key takeaways from the campesinos that I work with and visited on my last regional tour in October is that increased variability creates significant uncertainty around the arrival of the first rains in May. Many farmers are unsure about when, what, and how much they should plant for the season. These conversations played over and over again as I traveled from El Salvador to Guatemala, and then from Honduras back to Nicaragua.
According to Gerardo Santos, a field coordinator for Centro Educativo de Agricultura Sostenible (CEASO), “These fluctuations and changing climate dynamics are wreaking havoc in the most vulnerable areas and increasingly encroaching upon the majority of the country. Without the stability and predictability of the rains, campesinos are really in a difficult spot; they are in a struggle for survival.”
To assist these farmers, Trees, Water & People supports programs in sustainable agriculture, like those of our newest partner, CEASO in Honduras. A shifting paradigm in agriculture emphasizes climate mitigation and adaptation strategies like better soil management, conservation, rainwater harvesting, enhanced water storage capacity, agroforestry, crop diversification, and better and more resistant local seeds.
We believe that a more diverse, holistic approach to farming will protect campesino families in the long run, ensuring rural communities have access to food and other natural resources in a rapidly changing climate.
Here’s a report with lots of great pictures (for those who don’t speak Spanish) of several Nicaraguan communities where we will be doing the multi-year health study on how the Eco-stoves benefit local women. Partnering with us on this project are Colorado State University, PROLENA, and Casa de Mujer, a Nicaraguan NGO based in Granada.
