| description | The devastation of ecosystems in recent years is increasing the inequality and social conflict, and in particular, the marginalization of indigenous people, who in many cases are the rightful owners of the forestland. In this research we analyse the case of the Purepecha town of Cheran, Michoacan, community that in 2011, staged an armed uprising as protest for the illegal logging of their forests, in the face of the indifference of the authorities. The annual loss of forest cover between 2006 and 2012 was estimated by analyzing high resolution satellite images Spot (10 m), using a criterion based on the NDVI and the spectral signature. Soil / vegetation maps were obtained and validated for each year of the period studied; the comparison of annual maps allowed to generate the map of annual deforestation. In total, 9000 ha were deforested, equivalent to 71% of the vegetation area existing in 2006. Most deforestation occurred between 2010 and 2011 (2815 ha) and corresponds to the forest nearest the urban core area; many clearcuts were also burned. These results measure the problem of deforestation in Cheran and help understand the community’s reaction to the destruction of their forest. |

La devastación de los ecosistemas en los últimos años está aumentando la desigualdad y los conflictos sociales y, en particular, la marginación de los pueblos indígenas, que en muchos casos son los legítimos propietarios de las tierras forestales. En este trabajo se analiza el caso de la población purépecha de Cherán, Michoacán, comunidad que en 2011 organizó un levantamiento armado como protesta por la tala ilegal de sus bosques, frente a la indiferencia de las autoridades. A partir de imágenes satelitales Spot, de alta resolución (10 m) se estimó la pérdida anual de la cubierta forestal, entre 2006 y 2012. Utilizando un criterio basado en el NDVI y la firma espectral, se obtuvieron y validaron los mapas de suelo / vegetación, para cada año del período estudiado; la comparación de los mapas anuales permitió construir el mapa de deforestación anual. En total, fueron deforestadas 9069 hectáreas, lo que equivale a 71% de la superficie vegetal existente en 2006. La mayor parte de la deforestación se produjo entre 2010 y 2011 (2815 ha) y corresponde la zona más cercana al núcleo urbano; muchas zonas taladas también fueron quemadas. Estos resultados permiten dimensionar el problema de la deforestación en Cherán y ayudan a entender la reacción de la comunidad ante la devastación de sus bosques.
