    La reserva de la biósfera Zicuirán-Infiernillo se estableció debido a su extraordinaria riqueza en bio y geodiversidad; sin embargo, la región se caracteriza por un alto grado de marginación de la problación. Este mapa tiene como objetivo mostrar la conversación e intensidad de uso de la tierra, considerando la afectación a la vegetación natural.

    The Biosphere Reserve Zicuirán-Infiernillo established due to its extraordinary richness in bio- and geo-diversity; however, the zone is characterized by a high degree of marginalization of the people. This map aims to show the intensity of land-use change and the impact on the natural vegetation. By visual interpretation of Satellite Images and existing maps, we classified four moments of different land uses (1980, 1990, 2000 and 2008) at a 1: 100,000 scale. The combination of these four datasets allows us to identify three degrees of condition: permanent use, intermittent use and permanent preservation. The methodological approach allowed a better understanding of the development of activities within the reserve in the medium and long term; A situation that cannot be achieved with a single year study of the current situation, since land uses in the past can severely alter the environmental functions of soils and the conservation of biodiversity, even after several years. The map shows the occurrence of agricultural and livestock activities at the core area, in the past. Twenty percent of the buffer zone is already affected by degradation. Silvopastoral systems can minimize environmental degradation and produce commercial products such as milk and meat.
