Changes in land use is caused by conversion to grazing pastures and to agriculture,. Other factors contributing to deforestation (from the regression analysis in PACCCH, 2011) include: population density, distance to roads, distance to cities / towns, distances from agricultural or livestock areas, and gradients of slope.

In order to generate mathematical information on deforestation and degradation in the state, it was first necessary to generate vectors to obtain the first information coverage. SPOT scenarios are selected using a group of experts in the use of remote sensing as well as experts in the field. Second, the generated polygons were edited using the ARC Coverage and at 25,000 per frame. Third, tags were generated and validated, this process consists of exploiting to the maximum the hard information of the information system that is being processed. Most of these data come from the following sources: National Inventory of Forests and Soils of CONAFOR 2004-2010 and National Inventory of Erosioned Soils (INEGI) 2007-2010. Fourth, in order to analyze deforestation, vegetation cover and land use maps of the INEGI series 2, 3 and 4 were used on a scale of 1: 250,000, from 1993, 2002 and 2007. Legends of the maps were recoded to generate general and comparable classes. Recoding was carried out at two levels. At the first level, vegetation types were grouped into 12 types of vegetation cover, and at the next level, only two types of vegetation cover were defined, forest and non-forest. The first level was used to describe the types of changes and the second method was used as the main input for the deforestation model. Socioeconomic and physical data for the study of the factors influencing land use change were taken from the INEGI maps, censuses, the National Commission on Knowledge and Use of Biodiversity (CONABIO) and the Ecological Plan of Chiapas (PEOT). The road network was digitized using satellite images of SPOT5 as of 2009 (with a spatial resolution of 2.5 m). All geographic bases were transformed to the same projection (UTM zone 15, datum WGS84) and cut according to the limits of the study area.

In order to strengthen the state MRV system, it is necessary to develop and improve aspects related to information on activity data, emission factors and uncertainty analysis, information fusion, carbon inventories, and state models and transitions.
