Abstract

This work evaluated both loss of vegetal cover and urban growth over the last 22 years in the water- shed of Metztitlan River, Hidalgo, Mexico, with the purpose of monitoring land use change and plan- ning better the future land use of the study area. Both Landsat images of 1985 (Thematic Mapper, TM) and 2007 (Enhanced Thematic Mapper, ETM+) were used to made thematic maps using the maximum likelihood algorithm. These maps were validated and spatially compared using a change matrix. Two processes of change were detected: (1) annual deforestation (0.5 %), where the most active changes were from scrubland and forest to seasonal agriculture; and (2) urban growth (4.3 % annual rate) displacing agriculture, forests, and grasslands. PALABRAS CLAVE: Deforestacion, crecimiento urbano, Landsat, Hidalgo.
