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.

New clean cookstove in Guatemala

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.

International Day for Biological Diversity

By Gemara Gifford, Director of Development and Biodiversity

Happy International Day for Biological Diversity from everyone here at Trees, Water & People! “Biodiversity,” is a term that describes the variety of life on earth, from microorganisms to the largest trees. It can also refer to the number of different types of species living in a particular area. When there are high numbers of multiple species in a region, we call this a “biodiversity hotspot.”

Did you know that Trees, Water & People’s work occurs in many biodiversity hotspots? Central America, in particular, is one of the most biodiverse places on earth, with eight ecoregions and dozens of microhabitat types, it can support an incredible array of human, agricultural, and animal life. The small country of Guatemala, for example, boasts over 350 species of birds — that’s more species than the entire country of Canada! On the Pine Ridge Reservation in South Dakota, grasslands are known as the most threatened and biodiverse terrestrial ecosystem in North America – a forgotten ecosystem to say the least.

So, how does biodiversity loss affect humans?

At TWP, we know that biodiversity supports the overall health of the planet and has a direct impact on everyone. The next time you sit down to eat, think about this: every third bite of food you take is made possible by a pollinator, like a bee, bat, or hummingbird. Without a healthy biodiversity of pollinators, our current food system as we know it would collapse.

From an aesthetic point of view, many of us travel thousands of miles to see the rarest forms of life, like the odd cloud forests and creatures in Honduras. This brings us wonder, appreciation, and perspective. At the same time, it is important to be conscious about the carbon footprint that tourism has on the environment so that future generations may enjoy the diversity of life on our planet.

Honduran EcoTour
This cheery group joined Trees, Water & People on our first EcoTour to the Highlands of Honduras in January 2017.

This year’s International Day for Biological Diversity is focused on sustainable travel, and TWP is doing our part to take our place in this movement. Do you want to get involved with TWP to support the biodiversity of Honduras? Sign up for our eNewsletter to learn more about our second EcoTour to the Highlands of Honduras occurring in January 2018. Spots are limited! Together, we can support the earth’s biodiversity.

Celebrating World Water Day Every Day!

by Lucas Wolf, Assistant International Director 

World Water Day is an important day in a long list of significant calendar dates, sharing the same week with International Day of Happiness, International Day of Forests, and The International Day for the Elimination of Racial Discrimination. For those organizations that work with water, we know how critical it truly is as an element and necessity of all life on this planet. “Agua es vida, or water is life;” that simple yet profound phrase is uttered in communities across the Americas that have less water than most. It’s a statement and a refrain that captures the full awareness of the delicate nature of life and our total dependence on this one element.

At Trees, Water & People, we seek to expand on that awareness through programs that support enhanced water access in communities throughout Central America and the US. This year in Central America, our efforts with water will focus on rainwater catchment tanks in the Cordillera (mountain range) de Montecillos in the highlands of central Honduras. Our local counterparts, CEASO (Center for Teaching and Learning Sustainable Agriculture) were assisted by several TWP work trip participants this past January. CEASO’s philosophy towards water is holistic and profound; they see the importance of the forests, the soil, and the other elements existing in a balanced cycle that keeps our natural world healthy and able to support rural communities.

In El Salvador, a country ravaged by deforestation, our counterparts at Árboles y Agua para el Pueblo diligently work to keep their nursery humming with new plants, which will go towards diversifying a smallholder plot or anchoring trees and their roots to a critical watershed. In Guatemala, our partners at Utz Che look to build rural resilience and increased access to water for marginalized indigenous and campesino communities in all of the geographic zones of the country.

La Bendición, our special exchange community that has hosted two recent TWP work trips, seeks to find solutions for their water woes by capitalizing on the old coffee plantation infrastructure that they hope can be transformed to provide the community with more robust water security during the dry season. Here in Managua, work continues at NICFEC, the Nicaraguan Center for Forests, Energy, and Climate, which will serve as a demonstration center for best practices and methods to maximize water conservation and soil management for sustainable agriculture in a changing environment that is projected to see fewer rains in the future.

Meanwhile, in the rest of the region, there are additional stark reminders of the critical importance of water. México City continues to sink due to continued overdrawing of its aquifers, the number of planned resorts for Costa Rica´s booming Guanacaste region is in jeopardy due to a lack of available water, and here in Nicaragua, the land of the large freshwater lakes, many communities south of Managua face an acute shortage of water and virtual dependence on water distribution trucks.

In the United States, TWP stands with the Water Protectors of Standing Rock in their fight against the Dakota Access Pipeline (DAPL). Over this past winter, we provided off-grid solar heaters and generators to provide warmth and energy to the protest camps. These camps are the frontline resistance in a struggle for critical water and natural resource sovereignty. All of our strategic partners are focused on water, and we at TWP are striving to find ways to boost our water-related projects as we continue to hear how critically important it is for the survival of our communities.

Examples abound across the globe, and these stories of water stress are reminders that we must continue to focus our efforts on conservation, education, and innovation to stem the looming water crisis.

Connecting TWP’s Work through Migratory Birds

By Gemara Gifford, Conservation Scientist & TWP’s Development Director

Have you ever wondered where birds go when they fly south? October is that time of year when migratory birds to gear up to fly from TWP’s projects in the Northern Great Plains all the way down to those in Latin America. Golden-winged Warblers (pictured above), Black-and-white Warblers, Wood Thrushes, and Baltimore Orioles are just a few species that will winter in remote places like Guatemalan villages, Salvadoran cloud forests, Honduran coffee agroecosystems, and Nicaraguan dry forests.

Unfortunately, migratory bird populations are declining faster than most other avian species worldwide (State of North America’s Birds 2016) due to habitat loss on their wintering grounds and also because we know less about their conservation requirements in Central America compared to their breeding grounds in the U.S. and Canada. What we do know is migrants tend to live in the same places as the rural communities whom TWP works with, and can directly benefit from community-based development projects (Agroecosystems for communities and conservation).

Did you know that TWP’s clean cookstove, reforestation, and farmer-to-farmer training programs in Central America are especially helping to conserve migratory birds?

  • TWP’s clean cookstoves greatly reduce the amount of fuelwood families use to cook (an average of 50%) and as a result protect nearby forests and reduce deforestation.
  • Our reforestation programs in the U.S. and Central America improve degraded bird habitat, with over 7 million trees planted so far, and also protect the soils and watersheds upon which families depend.
  • By training hundreds of smallholder farmers in agroecology, agriculture can be diversified with multiple tree species and crop types which creates excellent migratory bird habitat while producing important foods and fibers for people.

For 18 years, our generous supporters have been helping us make the world a better place for people and the planet. Did you realize your dedication has also been helping to conserve threatened migratory birds?

On behalf of TWP, I am excited to invite you to join us on our newest endeavor with migratory birds – to follow them as they head south! This January, we’ll take 15 TWP donors and supporters to tour our new projects in Central Honduras. There we will conduct baseline bird surveys in cloud forest agroecosystems, and participate in on-the-ground bird conservation efforts through clean cookstove construction, tree planting, and ten days of cross-cultural exchange with our local partners at the Center for Education in Sustainable Agriculture in Socorro, Honduras.

With your continued support we can make the world a better place for people and wildlife. For more information about how to attend the 2017 Honduras Work Tour, or to learn about how TWP’s projects benefit birds, give me a call at 877-606-4TWP.

A special thanks to Ruth Bennett, Ph.D. student at Cornell University, for providing photos of her ongoing research in Central America to uncover the best strategies for conserving the Golden-winged Warblers in working landscapes.

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.

Marina Germeño reported that she was saving $3.33 per week – a significant sum over the life of the stove.

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!

TWP Celebrates International Day of the World’s Indigenous People

by Lucas Wolf, Assistant International Director

Today marks an important date on the calendar for indigenous communities around the world as the United Nations declares the International Day of the World´s Indigenous Peoples. This year, the Indigenous Peoples Day highlights the importance of education for indigenous communities worldwide.

For the international and national partners of Trees, Water & People (TWP) as well as the home office employees, every day is indigenous people´s day. Our tribal program in the US continues to break new ground on housing opportunities on the Pine Ridge Reservation, expand access to sustainable agriculture and improve food security, and work to reforest hillsides that have been decimated by fires and erosion. Our partnership with Henry Red Cloud has led to many educational opportunities for Native Americans over the years, such as business development courses, green job training, and sustainable building.

These two young Native American women were the recipients of our Solar Women Warrior Scholarship and learned how to install solar air heaters. Here they are working on fans for a heater.

Internationally, with our partner Utz Ché in Guatemala, we are also working to provide education opportunities, training, and capacity building for indigenous communities. In our primary community of La Bendición, where we led two work tours last year, we continue to support training in beekeeping (two youth leaders attended an apiculture and permaculture workshop at the Mesoamerican Permaculture Institute in San Lucas de Toliman).

La Bendición was founded in 2000 by two different indigenous communities that were displaced by the armed conflict in the 1990s in western Guatemala. They were relocated to an abandoned and defunct coffee plantation in the southeastern part of the country and were passed a bill for the value of the land, as assessed by the government. The discrepancy between the valuation of the land and what they received has characterized the next 16 years of their community’s existence. They have fought for dismissal of this over-inflated debt so they could get on with learning how to live separated from their ancestral land and people.

According to Oswaldo Mauricio, our primary coordinator with La Bendición and the director of Campesino exchanges for Utz Ché:

“The relationship between TWP, Utz Ché, and La Bendición contributes to an enhanced quality of life in many different ways. Together we improve the overall reforestation and conservation of the forests, protect the watersheds and the rivers, moderate the use of firewood and pressures on the forest, and help smallholder farmers diversify their parcels (productivity projects). All these activities are the primary focal point for the creation of better educational opportunities, both informal and formal. All of these developments help to ensure clean and healthy food production and consumption for the families of La Bendición.”

In addition to these efforts, our ongoing goal to build 500 clean cookstoves, in collaboration with Utz Ché and two Guatemalan improved cookstove producers, EcoComal and Doña Dora, is helping to train and educate other Utz Ché communities on the use and maintenance of the clean cookstoves. Your donation will allow indigenous communities in southern Guatemala to have access to these clean cookstoves, as well as the training they need to use and maintain them.
