RESUMO:

The chain of natural and anthropic events impressed a disparate landscape within the Brazilian Semiarid: the SeridóPotiguar. The region is detached from its adjacencies by the physical-natural and socio-cultural particularities that manifest themselvesthree-dimensionally inseparable on its surface. Furthermore, what seems to us to be uniform/homogeneous, when the observations and scale of approach are sharpened, moves like a true complex landscape mosaic, whose structure and dynamics, of each component geofacies, faithfully reflects the details of this floor and people. Mapping these landscape units (geofacies) and performing an integrated multiscale analysis (from climate zone to physiognomic facies) of their socioenvironmental dynamics understand the purpose of this work. But before that, it was necessary to know deeply the geographical epistemology capable of providing the appropriate optics for this. The geosystemic theory, by the French geographer Georges Bertrand, served us precisely as this theoretical-methodological prism, which allowed us to perceive/analyze the landscape systemically, mainly, from geofacies (abstraction), a physiognomicallyhomogeneous sector on the surface, according to its taxonomic system. In addition, the adaptations made by Diniz, Oliveira and Bernardino regarding the categories of analysis “Temporal and Spatial Dynamics of the Landscape”, based on Bolós; “Ecodynamic Landscape Typology” from Tricart; and “Cartography of Landscapes”, following Bertrand's own guidelines and relying on Brazilian cartographic experiences of Souza and Ab'Sáber. The techniques and procedures involved in this research refer mainly to cartographic modeling in a virtual environment of Geographic Information Systems. In sum, starting from cartographic contributions ofDiniz and Oliveirato higher taxa in Rio Grande do Norte (domain, natural region, geocomplex), the manual vectorization, through photointerpretation/teledetection, of landscape breaks, in the 1:50,000 in Sentinel-2 orbital images with spatial resolution of 10 meters and real color compositionR04G03B02. This was due to the construction of inductive interpretation sheets, which allowed, from the determination of a few cases (geofacies) and their validation in the field (with the aid of a field sheets), to assign a generalization to compartments of the same physiognomy. The obtained results allowed to elaborate a cartographic model that pointed to the existence of 30 different geofacies in SeridóPotiguar, which had their dynamics and distinctively landscape elements synthesized (systemic analysis), in text, based on the articulation of empirical data and thematic literature. Finally, the obtained data were qualitatively and qualitatively evaluated, in terms of spatial, absolute and relative extent, so that it was possible to undertake complements and greater robustness to the hypotheses of physiognomy and physiology of the seridoense landscapes, establishing a certain panoramic diagnosis of spatial and temporal situationand ecodynamics of these units.Thus, it is considered that the employed methodology allowed to advance in the knowledge of the seridoense landscape, in relation to previous works. Although, in addition, such contributions are expected to minimally achieve the goal of making, by virtuous paths of science, sertaneja life gradually more congruent with its environment, especially in the seridoensehinterland.
