Zoneamento das paisagens e suas dinâmicas territoriais da unidade de planejamento e gerenciamento Miranda (MS)/Brasil: uma proposta metodológica

Abstract

The Miranda Planning and Management Unit (UPG) corresponds to a territorial unit defined by the State Water Resources Plan of Mato Grosso do Sul (PERH-MS), a state policy aligned with the national guidelines set forth by the National Water Resources Policy (PNRH). The UPG Miranda covers an area of 42,993.78 km², overlapping entirely or partially with the territory of 20 municipalities in the central-western portion of the state of Mato Grosso do Sul. Notably, the UPG Miranda features a complex variety of landscapes due to the interaction between zonal and azonal elements within it. Thus, considering its landscape complexity, the thesis presented herein aims to understand the processes, factors, or forces that influence the dynamics of the landscape and territory of the UPG Miranda. To analyze these dynamics, a hybrid approach was adopted, recognizing that the landscape is always geoecological and that the territory is socially constructed. Accordingly, efforts were made to map elements that characterize the landscape and the historical-geographical evolution of the territory. From a methodological perspective, Landscape Cartography was applied as the main tool, aiming to identify, delimit, characterize, evaluate, represent, and describe the landscape units of the UPG Miranda. The upscaling approach was employed, grouping geosystems into complexes of geosystems, which were then aggregated into landscape units based on their structural and historical-anthropogenic characteristics. The analysis identified 168 distinct landscape units, grouped into 7 regional landscapes. Subsequently, each landscape unit was assessed in terms of its vulnerability and changes in land use and cover between 1985 and 2022. Based on this information, a zoning proposal was developed, indicating areas for preservation, conservation, attention, and exhaustion within the UPG Miranda.
