With sustainable agricultural projects, YIRABAH Gambia improves the living and nutritional situation of village communities by building village gardens in rural areas of Gambia. The goal is ecological agriculture and a resource-saving economy. Permaculture and agroforestry techniques are the basis for improving soil quality, building humus, reducing erosion and regenerating natural landscapes with high biodiversity. By creating an 8ha model farm, the village communities will be trained in these sustainable agricultural systems. These agricultural systems make an enormous contribution to protecting the environment and improving the climate. The model farm is currently an important producer of healthy fruit and vegetables and specially produced agricultural products, which are sold on local markets and contribute to food security. As a source of energy for our irrigation systems and drinking water supply to villages, we only use solar energy to operate the pumps in the deep wells. The “Light for Africa” project supplies private households with solar home lamps. The lamps are built in cooperation with the Youth Research Center in Sindelfingen with students in projects or MINT subjects and donated to students in Gambia. By replacing harmful kerosene lamps or candles with environmentally friendly home solar lamps, many household fires and respiratory health problems are prevented.
