What It Costs
By donating to this project, you will be contributing to saving millions of trees, and changing the lives of women and children in Malawi. The unit cost includes awareness training, construction of the fuel-efficient cookstove, and regular visits to monitor and train householders in its use and maintenance for a two-year period so that using and maintaining the cookstove becomes a way of life.


FURTHER INFORMATION ABOUT THE PROJECT
Why Is It So Important?
RIPPLE Africa is helping local communities to build fuel-efficient clean cookstoves in Malawi, Africa. RIPPLE Africa’s fuel-efficient cookstove is called the “Changu Changu Moto” which means “Fast Fast Fire” in Chichewa. The Changu Changu Moto:

  • AFTER: Mrs Longwe now has her Changu Changu Moto fuel-efficient cookstove

The Changu Changu Moto is a sustainable and locally produced fuel-efficient cookstove made out of just 26 mud bricks and a mud mortar mix. It is an adaption of a 16-brick design by Dr Larry Winiarski, and has been specially modified by RIPPLE Africa for Malawi 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

What We Have Achieved

So far, we have helped communities construct over 30,000 Changu Changu Moto cookstoves and have supported the householders to maintain and use them.

  • 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

How We Work

The Changu Changu Moto project is a great example of RIPPLE Africa working in partnership with the community to assess what is needed most and finding simple solutions quickly to meet these needs. Over the years, we have made several adaptations to the project such as:

When we first started the Changu Changu Moto project, the high demand and simple nature of the fuel-efficient cookstoves enabled us to roll out the project quickly in different areas.

While we expanded quickly, some of the households stopped using the stoves a few months after they are built. When RIPPLE Africa investigated the reasons for this, the solutions were often simple – for example, teaching families the correct use of wood for the fuel-efficient cookstove and that large branches and tree trunks well suited to an open three stone fire are too big for the Changu Changu Moto, so encouraging them to harvest smaller branches instead.

The solution was simple, but it took several follow-up visits to get the stove in use again.

To ensure better quality control, we now have a new monitoring and evaluation system:

The Project’s Future

Deforestation in Africa is a huge problem, but we believe that the use of our fuel-efficient cookstoves in Malawi will help save millions of trees. We expect that every stove built will continue to be in use for an indefinite period of time. With the longer monitoring period, our hope is that any problems are addressed during this period, so the stoves will be in use well into the future. Householders are taught to care for, repair, and even replace their stoves, so the outcomes from the initial investment will carry on for years to come. We have also helped families to plant their own trees which can be coppiced to provide a sustainable source of fuel close to where it is needed.

How To Make the Changu Changu Moto Fuel-efficient Clean Cookstove

Anyone with the knowledge can build their own Changu Changu Moto fuel-efficient cookstove, and we encourage people to copy our design! Just follow the instructions below.

  • 1. Make 26 mud bricks and dry in the sun
