Since the 1980s, the engineer Pierre Rabhi has been developing agroecology in very poor rural areas in Burkina Faso. This technique improves the soil’s productivity. A natural compost made with manure, clay, organic material and bones covered with straw replaces chemical fertilizers, puts nutrients back into the soil and reinforces the plants. In Gorom Gorom, an agroecology training centre and a hotel complex have been opened. Today, in Burkina Faso, 100 000 small farmers use agroecology and have regained their independence whilst respecting biodiversity.
