Hierarchical analysis of the intensity of change of land use/cover change and deforestation (2000-2008) in the Sierra de Manantlán Biosphere Reserve, Mexico
Hierarchical intensity analysis of land cover/use change is a quantitative framework of nested spatial analysis allowing for estimating changes from a change matrix at three levels of order: time interval, category, and transition. We present its application for two time periods (2000-2004 and 2004-...

| Resumo: | Hierarchical intensity analysis of land cover/use change is a quantitative framework of nested spatial analysis allowing for estimating changes from a change matrix at three levels of order: time interval, category, and transition. We present its application for two time periods (2000-2004 and 2004-2008) in the Biosphere Reserve Sierra de Manantlán , a highly heterogeneous study area in terms of vegetation type and land use. We used the cartography from INEGI at a scale of 1:50 000, updated by means of a Landsat ETM+ image for the year 2000, and SPOT 5 images for 2004 and 2008. Our analysis allowed for knowing in which time interval the general annual change rate was faster, which categories were most active and which latent, which were the target categories for active transitions, and if the pattern of change remained stable through time. We observed a fast annual rate of change between 2000 and 2004, in comparison with the period 2004-2008 with a slower rate of change. At the level of categories, we found high rates of deforestation of tropical forests to agricultural and livestock production uses, and latency in temperate forests having a slow intensity of transition towards these uses. In particular, long-established livestock production activities in the region appear as the promoting factor of deforestation, in its praxis on the territory expressing differentially in tropical and temperate forests. |
