GRET has been working in Mauritania since 1991 and encourages local initiatives and know-how in a participatory approach to meet the essential needs of the population, in line with public policies.

GRET provides appropriate and sustainable responses by creating, for example, youth reception and support centers to promote training and professional integration. It encourages a market-based approach, in particular by setting up water purification plants and promoting sanimarkets. Finally, it contributes to access to energy in rural areas through the development of multifunctional solar platforms and the production of an innovative alternative fuel.
