Doing our daily business, we might not think about it much using our so-called sophisticated water closets which cost thousands of dollars to maintain and waste millions of litres of fresh water daily.
People in a refugee camp aren’t that lucky. Doing their business can often be very dangerous, especially for women. The pollution created is also a big problem and so are unsanitary toilet compounds that can’t deal with the volume. There are no pipes or costly sewer systems.
Jay Abraham from Biologic Design in the UK has coined the phrase ‘tree bog’ for the toilet system that simply uses an old essential habit that people in his native England used daily. As he describes ‘People used to do their business in a bucket in a closet and they would have a separate bucket of soil and sprinkle it over each time a deposit was made. It kept the smell away.”

The way the tree bog works is quite similar. Its floor is built up high, at least 1.5 metres above ground level. The space under the floor is enclosed by 2 layers of wire mesh filled with carbon material (hay, straw, dry grasses) to allow air flow, absorb excess nitrogen and provide a visual barrier. The human waste is covered with sawdust, ash or soil and breaks down, feeding the surrounding area that’s planted out with trees, grasses and ground covers. In less than a year there are fast growing trees & fruits such as papaya to pick plus shade and biomass to refill the wire mesh carbon wall.
For 30 years Jay has been using his tree bog invention on his own property, fine tuning it to be shared with the world. He’s supported many projects that are building the toilets in refugee camps.
Permafund has recently funded a tree bog in the Kakuma Refugee Camp in Kenya. Established in 1990, the camp has some 60 000 inhabitants with many living there in limbo for years and years.
Since then, Marcelin Munga from Food & Health Education (FHE) in Kakuma has attracted more funding to build another tree bog. Members of the Permafund team were invited to tune into a live Zoom workshop with Jay Abraham beamed in from the UK. Marcelin hosted some 20 people from the compound including 3 cooks and 2 educators and a number of mothers with their babies, eager to start building their own tree bog. The workshop members used tools previously purchased with the Permafund grant.
There were some technical difficulties with the Zoom, but we got see the site and meet the group. Jay gave a report from another camp where one of the tree bog toilets had caught the attention of UNHCR. They inspected it with a negative attitude and the intention to knock it down but instead left impressed and gave the tree bog their tick of approval.
Donations made to Permaculture Australia’s Permafund that are over $2,00 are tax deductible in Australia and are supporting the grant program that assists organisations like Farm and Health Education to make a significant, practical difference in their community through the application of permaculture design principles and ethics.
