Citizen participation is increasingly well understood around the world, and its practice is spreading. In fact, it became a pillar of well-functioning democracies in the 19th century. This makes it desirable, desirable and even essential! It helps institutions build fruitful relationships with communities. These relationships enhance local quality of life because they explain decisions, which tend to be more sustainable and equitable. It is for the Urban Development and Decentralization Support Project (PAURAD), and as with many urban development projects in Benin, a facet of a dialogue between institutions and communities that leads to decisions that create social and economic capital.
