I am delighted today to get news of an award (Gender Just Climate Solutions Award) that was given to Sonita Mbah from Betterworld Cameroon. She actually received the award in 2017, but could not participate in the event. So today I saw the press conference recording from COP 24 which I will share below.
Sonita is championing the project we started together in 2015/16: the Africa Kitchen Revolution. We started in the local village with a group of women and taught them to build rocket cook stoves. The model for this was to teach a group by building or two example stoves in home kitchens and then ask those women to build stoves for the rest of the members of the group. In 2016 we held a training for trainers to be able to reach more women .
If you listen to Sonita’s statement the intention we set together has been moving forward:
Women are teaching women to build their own mud stoves.
Following this work in Cameroon I have shared the stove building process again in Kenya. And the rocket stove technology has been moving into a few other countries in Africa . Here’s an example from the Gambia by builder Alagie Manneh:
To me it comes down to this:
In order to serve the needs of the women who in many cases have no access to cash income, a technology has to be culturally acceptable, attainable, locally doable and independent from industrial processes . If the women succeed to spread the skills and continue to develop the design to suit their particular cooking needs, this project is successful.
If you are interested in trainings for stoves like this please contact me. I will be in East Africa in 2019 and can be available to groups or organizations.
Here now as promised the award presentation: Sonita is speaking at 16:25
I made a comment on Facebook recently stating how much I love to work with cob more than any other earth building method.
Here’s a selection of techniques and my impressions which help me decide which method to use in a specific location:
We’ve built Earthbag foundations in Canada (OUR Ecovillage ), Tanzania and Cameroon. The earthbag foundations work well and are low cost in places where stone isn’t available.
At a Natural building colloquium I filled long tubes with earth. Friends from the natural building movement have built beautiful domes and other homes with this method. I believe if there’s clay in your soil, forget the bags and build freely with that clay-soil. It’s a matter of location and what’s available.
Another amazing technique producing beautiful and stunning buildings is Rammed Earth. Layers of different colors tell the story of the earth at the location. I’m talking about rammed earth free of cement here, as its being done by several builders in Europe. This way of building requires serious formwork and planning. My personal experience is limited to observation, because in my work I’ve been in locations where that formwork is very difficult (expensive) to build. As a result rammed earth shows up on the high end of building cost and in larger scale buildings.
Many cultures have built with Mud blocks (Adobe) and still do so. Here in Cameroon I see homes being constructed with a mud-block infill system, using concrete for structural support: ringbeams and to bridge large openings. Local people have experience producing these blocks and will make their own when it’s time to build a home. Making blocks doesn’t require much: water and clay-soil. Fiber isn’t so commonly used but is useful to prevent cracks and to strengthen the blocks. You need a flat area to lay out the blocks to dry in the sun- this will take about a week. Then dry storage until construction begins. Building walls with blocks requires some skill- to build a house takes some practice at masonry work. And those blocks are very heavy to lift. However, depending on seasonal patterns and workflow, this can be a great way to build an earth home.
Compressed Earth Blocks
Compressed earth blocks (CEB’s) can be made with or without cement for stabilization in various shapes and sizes. Simple mechanical block presses require at least two people to work together – mixing the clay-soil (sometimes sifted) with a little water, then filling the form and compressing with the power of a long lever. Scale it up and you’ll see machines working with hydraulics taking the hard work out, but driving up the cost . The result is a firm, even block, sometimes interlocking. We’ve just finished building our dormitory walls with CEB’s – because we had the perfect soil on site, were too late in the season for sundried blocks , and had straight walls to build. We hired a local builder to lay the blocks as they came from the press. It got the job done.
Parallel to this process our volunteers were building with cob. We created some hybrid walls with the blocks to add sculptural details and bottles. And we shaped benches and a lounge area. A layer of cob fills awkward spots in the block walls (filling around posts etc) . I watched inexperienced building volunteers mix great batches of cob, build the walls and trim them. Everybody took on designing with bottles- allowing one individual to be the overall artistic eye.
And that’s where that statement came from.
Watching people, who have never built anything, confidently building something beautiful makes my heart sing.
We’ll be moving into Earth plasters next – where sculptures get refined and block-walls disappear behind a hand-applied layer of mud. Earthen plasters can be simple sand/clay mixes applied by hand or more sophisticated ones with additions of ingredients like mica or marble dust, finished with special trowels. It’s up to the availability of materials, skills and taste, desires and budget of the owner.
Hybrid of techniques
The beauty with all of the options above is the possibility of mixing things up. We call it hybrid homes- for example walls of cob on one side and straw-bale on the other. Or adobe with inserts of cob for bottles and other sculpted elements. All tied together with beautiful natural plaster finishes.
I’m heading to Kenya this summer to create a cabin for my host Joannah in a couple of workshops. She’s already collecting beautiful things to incorporate. Dreaming her space. Clearing the site.
When participants arrive we’ll work with a selection of techniques appropriate to the location and learn about decision-making in the process. This opens up the possibility of being creative builders in collaboration with others. We’ll be supporting the first stage of a learning center for permaculture in a protected forest.
So if you are so inclined, come to Kenya this August! You will get your hands muddy and experience a different sort of safari!
What does it take to get a building project off the ground in Bafut, Cameroon?
What will be our most successful ways to share knowledge and skills?
How can we work with the local community and have different interest groups meet and move together?
These and other questions are my focus at this time of beginning the work of building a meeting hall and small kitchen at Ndanifor Permaculture Ecovillage. The building will be the first part of a learning center where Better World Cameroon intends to teach “Permaculture African Way”. It will also demonstrate natural building and set the direction for the remaining development.
How did we get this far?
As a new volunteer last year I got engaged in the vision of a sustainable demonstration site in Bafut. This is part of a larger vision for Bafut as Ecocity for 2020. Part of this demonstration site is a farm, where people learn and practice organic growing and where Permaculture design is gradually being implemented.
A teaching site cannot fully operate without shelter for people. A design was developed for a learning center with accommodation in form of an Eco-lodge. Big plans for a small organization.
Ndanifor Permaculture Ecovillage is recognized by GEN (global ecovillage network) Africa as one of their African examples. This is bringing attention to us, and we expect to be hosting events at this site in the near future.
Close relations with Bafut Council and the local Palaces are also important elements for this vision.
In early 2014 I worked with a group of local women to build the eco-hut. This was a teaching course to get a natural building to the village. Entirely self funded, this building was built largely as volunteer effort, in one or two working days per week. Suffice to say it didn’t get completed in three months. The local builders did put a roof on it and now the cabin is waiting for completion.
Fast-forward a few months to November 2014.
We are back in Bamenda after a stay in Europe. While abroad I was able to secure some funding from LUSH Charity Pot for the next structure, the meeting hall.
Coming back here, that means expectations- word gets around and as soon as funding is in the game everyone wants a piece of it. It gets political.
I am a builder in a foreign land here,
and I must observe local custom and learn about the local hierarchies at play. In the village we have a local government represented by the Quarter-head. He reports to Bawum Palace (which is different from Bafut Palace). As an organization we are also working with Bafut Council and Palace, Bafut being the larger Region that Bawum is part of. Our immediate community are the people of Alegnwi, part of Bawum.
The leader of the women’s group we worked with last year is also a representative in the village. Are you confused yet?
Villagers here have responsibilities to their community.
They are for instance expected to participate in communal work parties, some of which have been taking place at the ecovillage site.If an individual isn’t regularly turning up at such workdays, his or her reputation suffers.
So here we are looking at putting together a team of builders from locals, to exchange skill and knowledge and to build a beautiful hall. I have a rough plan, so as we discuss with the builders we refine just how exactly this will be done.
Meetings before action
At an initial meeting at the siteI explained my vision of the building to three traditional builders and the leader of the women, as well as a couple of members of our organization.
The ball is now in the builder’s court to give us an estimate for the stone foundation and a post-and beam structure for the roof.
Before we actually make any contracts we will have to visit the Quarter-head and state our intentions and share our plan. Only with his sanction will this project be able to have the community-building effect that we intend.
Updates about the project
will be posted here occasionally and more frequently on Better World Cameroon facebook page.
