RIPPLE Africa is making fuel-efficient clean cookstoves in Malawi, Africa. RIPPLE Africa’s fuel-efficient cookstove is called the “Changu Changu Moto” and is a sustainable and locally produced fuel efficient cookstove made out of just 26 mud bricks and a mud mortar mix. The Changu Changu Moto fuel-efficient cookstove is an adaption of a 16-brick design by Dr Larry Winiarski, and has been specially modified by RIPPLE Africa after lots of positive trials and community feedback. RIPPLE Africa has worked with several types of fuel-efficient cookstoves over the years; however, we firmly believe the Changu Changu Moto is the most realistic and aptly suited fuel-efficient cookstove design for rural Africa we have ever seen!

  • Three-stone fires typically use three large bundles of wood per week

  • Each year, about two million people worldwide die prematurely from smoke inhalation from cooking fires
    Each year, about 1.6 million people worldwide die prematurely from smoke inhalation from cooking fires
  • Children regularly suffer burns from falling into three-stone fires or when their clothes catch fire

Here are some of the reasons why:

  • Only one bundle of wood is needed each week for a Changu Changu Moto cookstove

  • Two or three small pieces of wood are used at a time, and the bricks retain the heat to prolong cooking

  • Less smoke is produced, the cookstove is safer and cleaner, and it benefits from a double burner

Why This Is Important

Deforestation is one of the greatest issues facing Africa today. The effects of deforestation are tangible: less rain, hotter climates, soil erosion, and drought bring famine, poverty, and starvation. One of causes of deforestation is the high demand for wood used for cooking fires. In Malawi, 95% of the population use wood or charcoal for cooking every day, and almost 100% in rural areas! The Changu Changu Moto fuel-efficient cookstove reduces the demand on Malawi’s forests, as it uses up to 66% less wood than a traditional three-stone cooking fire. Just one Changu Changu Moto fuel-efficient cookstove will save hundreds of trees in its lifetime. (Imagine the savings if everyone in Malawi used one!)

The Changu Changu Moto fuel-efficient clean cookstove is also important to healthcare. According to the World Health Organisation, 1.6 million people die prematurely from smoke inhalation every year — that’s more people than die of malaria! These effects are most poignant for women and children who spend most of their day around the fire. The Changu Changu Moto fuel-efficient clean cookstove reduces smoke inhalation as it produces substantially less smoke and is located at the side of the kitchen, keeping families out of the line of the smoke during their day-to-day activity. The Changu Changu Moto also reduces the chance of incurring serious burns: 60% of the families surveyed in our community said they had at least one family member who had suffered serious injury from clothes catching fire or from falling into a traditional three-stone fire.

Lastly, the Changu Changu Moto fuel-efficient cookstove is important because it improves the quality of life for women in Malawi. Culturally, women in Malawi have a huge amount of responsibility, including the cooking and collecting of firewood. For a typical Malawian woman, collecting enough firewood for the family can require three or four separate trips each week, each trip taking between three to five hours! The Changu Changu Moto fuel-efficient cookstove reduces that labour by up to 10 hours per week, drastically improving the quality of life for women who have it quite tough as it is!

What it Costs

The Changu Changu Moto fuel-efficient clean cookstove is a fantastic and cost-effective fuel-efficient cookstove option for rural Africa. By donating to this project, you will be saving hundreds of trees, and changing the lives of women and children in Malawi. The unit cost includes awareness training, construction of the cookstove, and regular visits to monitor and train householders in the use and maintenance of the cookstove for a two-year period so that using and maintaining the cookstove becomes a way of life.
