The most common type of biogas system, and the most widely adopted in China and India, is a fixed dome system. Its construction requires skilled technical expertise and complex logistics, making installation expensive and time-consuming. Fixed dome systems are permanent installations, so secure land tenure is a prerequisite. These challenges make it difficult to adopt fixed dome systems in developing countries, particularly in Africa. As a result, many systems have failed and adoption rates have been low.

Another type of biogas system, manufactured in Kenya, is Flexi Biogas, a flexible above- ground system that is simpler and less costly to build and operate. This system does not require agitation and the digester is not a sealed tank but simply a 6m x 3m plastic bag made of PVC tarpaulin.

Indigenous peoples have rich and ancient cultures and view
their social, economic, environmental and spiritual
systems as interdependent. They make valuable
contributions to the world’s heritage thanks to their
traditional knowledge and their understanding of
ecosystem management.
But indigenous peoples are also among the world’s most
vulnerable, marginalized and disadvantaged groups.
We must ensure that their voices are heard, their
rights respected, and their well-being improved.
