Proposição de zoneamento para a conservação de áreas úmidas

Abstract

Wetlands are permanent or periodically flooded ecosystems that provide numerous environmental services, including biodiversity, and are characterized by high productivity. The devastation of important wetlands along streams, rivers and in interfluvial areas can lead to the loss of these ecosystem services that are fundamental to the ecosystem from an ecological, economic and social point of view, including biodiversity. For the effective preservation of these areas, it is necessary, first of all, to know them, to know their geographical location, their territorial extension, in short, it is necessary to characterize these areas so that it is possible to later invent them. One of the steps in the wetland characterization process is its delimitation. For this purpose, the best currently available method is the mapping by the use of remote sensing data. In Brazil, even with laws that support these areas, preservation is still a challenge, as it is a highly productive country. In order to carry out an environmental diagnosis in order to identify the conservation status of these areas, geoprocessing stands out as an important instrument for their identification, because through the Quantum Gis 2.8 software it was possible to perform a soil classification and identification of wetlands. Thus, it is possible to affirm that the study performed contributed significantly to the management of the wetlands of Douradina-MS, once the main threats to the region were identified, where inappropriate use of different economic practices are contributing to the degradation Of them, leaving no part of the natural wetlands.
