High demand for firewood threatens forest areas

With 68% of the total energy consumption by household, biomass is the most important energy resource in Kenya, as it is in many other African countries. In rural areas, the consumption of fuel wood is as high as 80%.

The project is carried out in the Nairobi River Basin, which is located west of Kenya’s capital. Thousands of dairy farmers, each with two or three cows on their property, live in this area. On average, these farmers consume over ten kilograms of firewood per day, mainly for cooking. The high demand for firewood poses a serious threat to the surrounding forests. If the overexploitation of this resource continues, firewood will become increasingly scarce and local biodiversity be negatively affected. In addition to firewood, people in the project area also use kerosene and gas for cooking.

Clean biogas for cooking, fertilizer for the fields

In order to reduce consumption of firewood, gas and kerosene, the atmosfair project subsidizes small biogas units (2-3 m³) for dairy farmers in the area that produce renewable biogas. The biogas units run on cow dung and other agricultural wastes. During the process of biogas generation, slurry is produced as a by-product. Due to its high nutrient content, farmers can use this by-product as an agricultural fertilizer. To operate the biogas units optimally, every household must own at least two cows.

Our partner

The biogas units are being built and installed by atmosfair and the Kenyan organisation Sustainable Energy Strategies (SES). With support from the Indian NGO Action for Food and Production (AFPRO), atmosfair and SES trained local masons in the construction of biogas units, who are now training their own handymen. For the construction of biogas units, only local products are used.

The project is currently supported by Grüner Strom Label e.V.. With the additional funding, we lower the investment costs of biogas units for the end users so that more people can afford clean biogas for cooking.
