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.

500 More Clean Cookstoves in Guatemala

By Sebastian Africano, Executive Director

Since 2006, Utz Che’ has been a tireless advocate for over 40 indigenous Guatemalan communities committed to protecting and sustainably managing their forest resources. Utz Che’ acts as a loudspeaker for indigenous causes and concerns, which are otherwise easily dismissed from the public discourse and policy-making dialogues.

Trees, Water & People (TWP) was introduced to Utz Che’s leadership in 2010 and has worked with them to add fuel-efficient cookstove technology to their services to reduce pressure on the local forests from which fuelwood is harvested, as well as reduce indoor air pollution. After several years of prototyping designs with Utz Che’ communities and Guatemalan manufacturers, last year we embarked on the full-scale implementation of 500 clean cookstoves manufactured by two local enterprises — ECOCOMAL and Estufa Doña Dora. The project was so successful that this year we are raising funds to install 500 more in high-need communities.

Learning about the new Doña Dora stove
In 2016, this community in southern Guatemala received Doña Dora stoves and were all trained by Doña Dora employees on how to install, use, and maintain their new clean cookstoves.

The cookstove models selected for this project are partially pre-manufactured for consistency but are installed in a brick and mortar body constructed by trained community members. In 2016, this included 159 men and 371 women. Hands-on training in installation, use, and maintenance of the stoves increases local investment in the program through sweat equity and allows community members to become more intimate with the technology. Community engagement improves the local support network around the cookstoves.

Cooking is a very personal tradition in Central America, so new technologies must be able to cook the same foods, with the same fuels, in the same amount of time as the traditional designs if they are to be accepted by all members of society. Trees, Water & People’s years of expertise, coupled with a locally fine-tuned design, and the trust and rapport that Utz Che’ has with its member communities make for an extraordinarily effective, participatory, and meaningful partnership.

Guest Blog: 500 Clean Cookstoves Installed in Guatemala

By Jeff Abbott, Independent Journalist

Jeff Abbott is an independent journalist based in Guatemala. He covers human rights, social movements, and natural resource rights in Central America and Mexico. Recently Jeff visited some of TWP’s projects in Guatemala and spoke with recipients of our clean cookstoves while photographing the delivery and installation process.

During my visit to the communities of Jocote, Jicar, and Barrio Belice, in the municipality of Quesada, Guatemala, I was able to speak to several community leaders, who shared that the origins of Utz Che’ and Trees, Water & People’s clean cookstove project came after seeing similar programs in other places. At its core, the drive for the endeavor comes from a place of deep concern over the deforestation in the mountains above their community.

Besides the health benefits of these stoves, which channel smoke out of the kitchen via a chimney, they also require far less firewood than the traditional open fire. As many beneficiaries of this project live in the peri-urban outskirts of Quesada, where fuel is purchased more than collected, this translates to a considerable reduction in household fuel expenditures.

Vera Alica with her new clean cookstove
Vera Alica’s new clean cookstove will use up to 70% less fuel than the open fire she was using to cook before her stove was installed.

Vera Alicia (pictured above) is one of the recipients of the stove in the Aldea of Jicar. The 47-year-old mother of nine stated that the stove has allowed her to save substantial money on firewood. Another beneficiary, Marina Germeño (pictured below), reported that she was saving $3.33 per week – a significant sum over the life of the stove. Vera Alicia also explained that it has not changed her cooking habits, but that she has seen a dramatic reduction in the amount of smoke in her kitchen.

This clean cookstove project in the communities of Quesada and two other departments in Guatemala’s arid corridor, provide an important opportunity for the residents who have benefitted. Short-term, tangible benefits of the project are the immediate economic savings that families experience via the significant reduction in firewood used for cooking. Most residents quickly acknowledged this benefit, expressing the savings they had noticed.

Furthermore, residents are conscious of the environmental benefit that the decreased reliance on firewood brings to their communal lands, which TWP has helped to reforest in years past. Apart from protecting local forests, another beneficiary, Marthy Corina Soto, also expressed that a major benefit that she has noticed since receiving the stove is the fact that she does not burn herself as easily, as there is no open flame. “Everything has been magnificent,” echoes her husband, Angel.

Trees, Water & People is happy to report that, with our partner Utz Che’, we were able to build and install all 500 cookstoves in three departments of Guatemala. We truly have the best supporters in the world and are humbled by your contributions!

We are still working to raise funds for this program to follow up with each family to ensure that they have transitioned completely to their new stove and to assess any barriers to full adoption.  We have found that following up with families shortly after their new stoves have been installed is critical to the family using their clean cookstoves consistently and correctly. Monitoring after the installation is an important part of our work and it is only possible with your support!

Guest Blog: Estufa Doña Dora Teams up with Trees, Water & People

by David Evitt, co-founder and CEO of Estufa Doña Dora 

A staggering 57% of Guatemalan energy use comes from firewood. That single statistic puts the challenge of clean cooking in context. In rural areas, there is near total dependence on biomass energy. For those families, wood for cooking is their only significant use of energy.

70% of Guatemalan families cook with wood, mostly on improvised open fire stoves that leave the kitchen filled with smoke, leading to disastrous health outcomes. Household air pollution globally causes more deaths than HIV/AIDS, tuberculosis, and malaria combined. The country-level outcomes for Guatemala are similar, with 5,000 deaths a year caused by indoor air pollution, and acute respiratory infections aggravated by kitchen smoke being the leading killer of children under five.

Yes, the challenge of clean cooking in Guatemala is monumental. However, we see this as an opportunity. Estufa Doña Dora is a Guatemalan social enterprise founded on the idea that a clean cookstove should have more in common with consumer durables, like blenders and TV’s, even when used for humanitarian interventions. We recognize that a cookstove is mission-critical professional equipment for Guatemalan cooks.

The most important criteria for a Guatemalan cookstove are that 1) it has the necessary capacity for the family’s cooking needs, 2) it cooks quickly and well, 3) it’s affordable, 4) it gets the smoke out of the house, and 5) it saves wood. Estufa Doña Dora has been working since 2011 to deliver products that meet all those criteria. We are the only company in Guatemala that sells a majority of efficient cookstoves directly to individual families.

We divide families into two broad groups: wood buyers and wood collectors. The wood buyers are able to pay for a cookstove over time by getting a loan through our microfinance partners, and redirecting their savings on firewood to pay for the stove. Wood collectors do not have a ready income stream to invest in a stove. That is where international development organizations like Trees, Water & People (TWP) can focus their efforts for maximum impact.

Learning about the new Doña Dora stove
This community in southern Guatemala is learning about their new Doña Dora stoves.

We are proud to partner with TWP and Utz Ché to bring Doña Dora cookstoves to 414 families gathering wood in the Camotán, Chiquimula and Quesada, Jutiapa areas of southern Guatemala. These types of partnerships are critical to bringing the capacity, function, and ease-of-use of the Doña Dora in a way that meets the needs of the project and families. To lower costs and involve the family, Utz Ché has been delivering the pre-built, internal components of the stove and they have then been training the families on how to build the supporting structure from concrete cinderblock or Adobe, according to their preference and budget.

In following up with the first community to receive the stoves, 98% of families reported loving the stove, having no problems, and saving 50% on firewood. We were able to give extra attention to the families that needed additional support adapting to the technology, and are confident that they will adapt quickly.

Please support TWP and Utz Ché in helping eliminate household air pollution and reduce firewood consumption in 500 Guatemalan homes. Your support will help change the way these families cook their food for generations to come.

Guest Blog: StoveTeam International and Trees, Water & People Team Up!

Introduction by Sebastian Africano, International Director

At Trees, Water & People (TWP), we’re one organization in a global movement to improve living conditions for some of the world’s poorest families. Working together with other groups expands our reach and our impact, which is why we are thrilled to collaborate with our colleagues at StoveTeam International to improve cooking conditions for rural Guatemalan families. Please enjoy our guest blog post by Katie Laughlin of StoveTeam International, and support TWP’s goal of funding 500 stoves for Guatemala in June 2016!

by Katie Laughlin, Program Director at StoveTeam International

In Guatemala, 2.4 million families cook over traditional open fires. Without action, that number will likely increase to 2.8 million by 2030. That’s a scary vision for the future of Guatemala, a nation whose iconic landscapes of virgin lowland jungles and highland cloud forests are already disappearing alarmingly fast due to escalating rates of deforestation; and where burns and respiratory infections caused by harmful smoke are responsible for more than 5,000 deaths a year.

Natividad Ortiz, who is the third beneficiary of the stoves in the community of El Tarral
Natividad and her family are the third beneficiaries of a clean cookstove in the community of El Tarral in southern Guatemala.

StoveTeam International is motivated to change this grim prognosis by supporting efforts, large and small, to provide communities access to efficient and safe cooking alternatives. That’s why we are excited to support Trees Water & People’s effort to provide hundreds of clean cookstoves to families in Guatemala!

This summer, TWP and its partner, Utz Ché, will provide 500 stoves to three critically poor communities in Chiquimula, Jutiapa, and Escuintla. A StoveTeam International-sponsored cookstove factory, EcoComal, will provide many of these stoves. In StoveTeam’s experience, three elements are vital to success when working with local entrepreneurs to create independently owned and operated cookstove businesses – trust, local knowledge, and a passion for making a difference. TWP, Utz Ché, and EcoComal bring all three to their work with communities to create a culture of clean, smoke-free cooking that can be passed on to the next generation.

Guest Blog: Investigating the Health Impacts of Cookstove Pollution in Honduras

Honduras cookstove study
Women emerge from the mist carrying bags of potatoes in Zacate Blanco.

by Bonnie Young, Colorado State University

When you think of torrential downpours, mud-slick roads, and backcountry hiking, you might imagine an exciting episode of “The Amazing Race.” Our fieldwork in rural western Honduras was similar, although we lacked a camera crew and the promise of a grand prize.

As a postdoctoral researcher with Colorado State University (CSU), I worked side-by-side for two months with Sarah Rajkumar, another CSU postdoc, Jon Stack, a CSU volunteer, and Gloribel Bautista, a local coordinator. Our goal was to work with communities to enroll 500 women in villages in Yamaranguila and Intibucá. This was our first step in a three-year project to investigate the health impacts of cookstove-based pollution, and to learn about women’s perceptions and behaviors with different stove types.

Western Honduras
Beautiful views in this agricultural region in western Honduras, which boasts the highest elevation in the country of over 6,000 feet.

Most people in this agricultural region use wood-burning stoves to cook, heat their home, dry clothes, and generate light. Poor-functioning and inefficient stoves create household air pollution and demand excessive amounts of wood, meaning harmful effects on people’s health and the environment. Women and children often have greater exposure to indoor smoke since they tend to spend more time in the kitchen.

Knowing the importance of this research and its potential impacts fueled our daily slogs from house-to-house during the rainy season, where every hot cup of coffee and fresh corn tortilla felt like a grand prize.

Stay tuned for updates on this project during our next field session, February – May, 2015.

Infographic: Clean Cookstoves Save Lives!

clean cookstoves infographic

Around the world, billions of people are still dependent on wood and other forms of biomass to cook every meal. Cooking with wood over an open fire causes a variety of environmental, economic, and human health problems.

Since 1998, we have been working with our partners and local community members to design clean cookstoves that greatly reduce deadly indoor air pollution, deforestation, and high fuel costs. These cookstoves are designed according to specific cooking needs and cultural context, which is why they can look very different from country to country. However, all of these stoves have one important thing in common: they make cooking much safer for women and their families.
