The Mapimí Biosphere Reserve (BR) is located in the states of Coahuila, Chihuahua, and Durango in Mexico. This BR is characteristic of the Chihuahuan Desert, and is home to a great diversity of flora and fauna. CONANP has spearheaded efforts to develop the Mapimí Basin Complex Climate Change Adaptation Program (PACC), which integrates measures to address climate change. Grassland restoration is an adaptation measure that was identified in a participatory manner and the success of its implementation was determined by the participation of the community and organized civil society, in this case Pronatura Noreste, A.C., among other success factors described in the building blocks. Five years after the restoration work began, an increase in vegetation cover was documented, including the establishment of more than two species of annual grasses and one perennial grass, in addition to various herbaceous plants.
