A destructive cycle exists around the shores of Lake Victoria in Tanzania. Fish stocks have decreased significantly over the past ten years thanks to over-fishing. The local population has responded with intensified and diversified farming activities. In turn, the nitrates and phosphates from fertilisers and sewage have led to a eutrophication of the lake, including the spread of invasive plants.
SEED is an initiative by RONGEAD, a French association that channels public and private funds to assist LDCs. The project aims to break the vicious cycle by using organic waste to produce biogas and organic fertiliser with the compact biogas systems (CBS) in targeted communities in the Lake Victoria region of Tanzania. These systems reduce environmental damage while facilitating local development.
During its pilot stage, SEED has established a clear supply chain for compact biogas systems and trained eight entrepreneurs in the use of the CBS floating drum technology, which received an Ashden Award in 2006. This up-scaling project aims to make the technology more affordable, and promote small agro-food processing in the area.
