Analysis of land cover dynamics in eastern of Chaco between 2015 and 2019

Sumario:Changes in land use and coverage are a dynamic and complex process that links reciprocal action between the natural and anthropic systems of the territory. For any attempt at territorial planning, it is necessary to measure the spatially and temporally modifications. In this sense, land cover cartography based on processing techniques satellite image allows the generation of statisticalcartographic results that help to get a better understanding of changes and their impact on the environment. Much of eastern Chaco is a Ramsar site, with extensive biological diversity, environments with unique character, but on the other side fragile in the face of changes that alter its balance. The mapping of changes is a fundamental input for governments, institutions, and researchers related to climate change, conservation and sustainable use of natural resources. The main information input was raster data, offered by the Copernicus Global Land Service with a spatial resolution of 100 m between 2015 and 2019. General-purpose GIS software was used for the processing, while the analysis of the changes was carried out with a specific module called Land Change Modeler. To visualize the spatial distribution of the processes, change and permanence systematic transitions were mapped in terms of gains and losses. In this process, it is observed that the greatest gain was for wetlands (50,000 ha), while the greatest losses were in herbaceous and forest with 28,000 and 22,000 ha respectively.
