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

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 cartog...

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. Los cambios en el uso y cobertura de la tierra son un proceso dinámico y complejo que vincula la acción recíproca entre los sistemas naturales y antrópicos de un territorio. Para cualquier intento de planificación territorial, es necesario medir espacial y temporalmente las modificaciones. En este sentido, la cartografía de cobertura de la tierra basadas en técnicas de procesamiento de imágenes satelitales, permite generar resultados estadístico-cartográficos que ayudan a comprender mejor los cambios, y su impacto en el ambiente. Gran parte del este chaqueño es un sitio Ramsar, con una amplia diversidad biológica y de ambientes que le imprimen un carácter único, pero también una gran fragilidad ante cambios que alteren su equilibrio. La cartografía de cambios es un insumo fundamental para gobiernos, instituciones, e investigadores relacionados al cambio climático, la conservación y el aprovechamiento sustentable de los recursos naturales. El insumo principal de información fueron datos ráster, ofrecidos por el Copernicus Global Land Service con resolución espacial de 100 m en los años 2015 y 2019. Para el procesamiento se empleó un software GIS de propósito general, mientras que el análisis de los cambios se efectuó con un módulo específico denominado Land Change Modeler. Con el objeto de visualizar la distribución espacial de los procesos de cambios y permanencias, se cartografiaron las transiciones sistemáticas en términos de pérdidas y de ganancias. En este proceso se observa que la mayor ganancia fue para humedal (50.000 ha), mientras que las mayores pérdidas fueron en herbáceas y bosque con 28.000 y 22.000 ha respectivamente.
