ResumoThe Sierra Norte de Puebla ( SNP) is a region with a high biological and cultural diversity where the coffee plantations have had a relevant role in the land use cover characteristics. The objective of this study is to know the spatial patterns of the dynamics of the land use/cover change in the period 1988-2003, relating these patterns with acti- vities of the coffee economic sector in the SNP. The change analysis was realized by means a supervised classification of two Landsat satellite images. The geographic or spatial change was evaluated overlaying the two land use/cover maps (1988-2003) obtaining a change matrix. Over the 15-year period considered, 58.4% of the study area remai- ned unchanged and 41.6% had some class of change. The main changes were from induced grassland/agriculture to shade coffee plantations/intermediate secondary vegetation of tropical montane cloud forest or to tropical rain forest/ permanent citrus crops. The change-patterns of the land use/cover dynamics are related to the current process of the coffee-sector problematic in the region.
