Meaningful impact-read about the essence of empowerment and sustainability

Clean, safe water comes to the people

The Maasai Stoves & Solar Project strives for the greatest possible direct impact from the introduction of smoke-removing efficient stoves.

From the onset, this has meant better health for women and their children. Because the focus goes beyond a single technological solution, the impact soon spreads and grows. The International Collaborative engages the people as they embrace the idea that problems can be solved through organizing for collective action.

Something new emerges in the midst of idea generation, engineering, design, and resource planning. Participants soon discover the greatest impact is on themselves, as a community. There is a new optimistic celebration of power and the realization of the possibility of genuine life improvement.

The International Collaborative believes that the essence of “empowerment” is the internalization and retention of that creative energy.

Empowered people are those who are able to do things they believe should be done.   And the essence of “sustainability” is the increasing permanence of that new spirit of engagement. 

Once people experience the joy of working together to make life better, they will want to continue to experience that joy

Scope of Action

Impact Summaries

Home improvement and impact on women’s lives

The Maasai Stoves & Solar Project addresses the indoor smoke in the homes of pastoral people in East Africa caused by cooking on open wood-burning fires. This is a profound international health issue that affects millions in the developing world.

The Project designs and installs clean-burning and efficient wood-burning chimney stoves and solar panel-based electrical systems in the homes of the people. In addition, we install settlement-wide solar panel-based micro-grid electrical systems. We purchase and import components of the photo-voltaic systems but produce stoves locally.

Stoves & Solar

Over the course of its lifetime, The International Collaborative durable and efficient Model Four stove reduces carbon dioxide emissions by more than 20 tons.

Having a light at night is a dramatic lift from poverty. In the small homes of the Maasai even a few watts makes a huge difference in life. In the Maasai areas near the equator, dark nights are long year-round. In addition, cell-phone charging in the home is cost-efficient, and keeps the phone safe and away from tampering.

  • Stove use saves 10-12 hours of wood-gathering labor each week
  • Reduction of the polluting particulate level from cooking smoke by 90 percent, alleviating chronic coughing and head congestion, primarily in women and children
  • One stove reduces carbon dioxide emissions by 3.6 metric tons per year
  • Reduction of carbon monoxide levels in the home by 90 percent, eliminating low-level poisoning
  • Eliminated the danger of burns to toddlers caused by open cooking fires in their homes
  • Reducing the risk of smoke-related lung disease in children
  • Pollution-free and odor-free lighting motivates kids to read and study and makes women’s evening and night work much more pleasant
  • Maasai women who join stove installation teams are profoundly appreciative of the opportunity to learn to use tools and master construction and design challenges, and report feeling authentically empowered
  • Each stove saves the woman of the house 10-12 hours of weekly wood gathering labor
  • Each stove saves 120 pounds of firewood per week, reducing deforestation
  • Greater appreciation of the power of the collective, versus what an individual woman can do alone
  • 6000 stoves installed as of 2023

Maasai Stoves & Solar micro-grid electrification impact

Light at night in the boma

From the beginning, the Maasai Stoves & Solar Project has integrated electrification on a home-by-home basis. We continue this approach on a significant scale.

Sixty bomas now have micro-grid electrical service

Since 2014 we have also brought shared electrification through micro-grids. The micro-grids supply power to all the homes and corrals of Maasai family settlements, or bomas.

  • For the first time, settlements have light at night
  • Sixty bomas now have micro-grid electrical service
  • The homes have clean stoves, lights and phone chargers
  • Maasai men and women are trained in solar installation and electrical maintenance

Safe water chlorination systems impact

Forty liters of safe water a day provides a woman with drinking and bathing water for her family without having to treat it herself. Women have a variety of ways to handle badly polluted water, from doing nothing to boiling it at the cost of more energy and hours of work.

With 35 children per thousand dying of water-borne disease before the age of five in these communities, and many more sickened by the pollution, safe water is a crucial life-saver.

The installation of a 5,000 or 10,000-liter per day pond-side chlorination systems costs only $35 per family. Maintenance with the necessary chemical treatment costs a few cents per month per family.

  • Each system is successfully managed by community members responsible for the surface pond use.
  • System size is set to provide 40 liters per day for each family using that water source
  • Costs are low and health impacts very significant and positive

Livestock management impact

At the International Collaborative Manyara Feedlot

The Maasai’s traditional herding practices have made them East Africa’s most famous pastoralists. But because of periods of serious drought in recent years, and the unpredictable weather in the changing climate, new approaches are essential.

Established in 2017, the Project’s Manyara feedlot is already having an impact, recognized by the Uhuru Torch award that year.

Climate change is already here for rain-based livestock-based economies like the one for pastoralists in the plains of northern Tanzania. There will continue to be some seasons with plenty of rain and grass when traditional livestock practices will still function for the people. But it is important to expand flexible solutions for economic and social survival and to keep pastoralists from resorting to moving to urban slums.

The International Collaborative feedlot provides a model of the flexibility required. It demonstrates how to care for cattle with purchased hay and food supplements when weather conditions require it.

Impact of women organizing for social strength and independent income

Women need social connection and independent income

In a polygamous and patriarchal society, such as the Maasai, women need social connection and independent income.

The International Collaborative organizes two types of women’s groups. These are widow’s groups and groups the women choose themselves based on family and social relationships but not marital status.


In collaboration with the Global Fund for Widows, the ICSEE (T) organized 19 groups in seven villages. Each group of 25 women received excellent training. They now operate their cooperative banks and manage a collective livestock business. The ICSEE (T) Project Organizer succeeds in linking the women to the village authorities for additional support benefits.

Self-forming women’s groups

Women form groups according to their own social criteria, gather the initial capital for livestock fattening businesses and come to the ICSEE (T) for additional capital and training.  As of August, 2023 there are 20 of these groups, with more in process.

Maasai Stoves & Solar Installation Trainers and Teams

The stove has a chimney and needs installation and is therefore an opportunity for employment. This is a special feature at the core of the impact of the Project. Team leaders train women in new villages to become installation experts. Trainers and trainees earn money for this. Installing women have organized themselves as the Monduli Pastoralist Women’s Organization (MPWO), and are also engaged in livestock fattening businesses.
