The protected areas administered by the National Natural Parks of Colombia (PNNC) present socio-environmental conflicts with the peasant communities, derived from the situation of use, occupation and tenure within the Protected Areas (PA). This aspect has been altering the state of conservation and its associated ecosystem services. In this sense, the Galeras Flora and Fauna Sanctuary (SFFG) has implemented since 2007 the Participatory Ecological Restoration strategy, which has reduced the pressures caused by cattle ranching and agriculture, while allowing the recovery and restoration of the PA’s altered areas. Parallel to this process, in 2018 the SFFG initiated a process of environmental agreements between the PNNC and the farmers who use land within the PA, in order to fulfill its conservation mission and thus involve them in the mission processes.
