SUMMARY:

In the context of research on Seasonally Dry Tropical Forests – FTSS, the process of evolution and adaptation allowed the phytogeographic domains of the Caatingas to be established in the semiarid region of Brazil, which is the most populated semiarid climate area in Brazil. Mundo, corroborating the process of fragmentation and loss of ecological functions. These anthropic pressures increase the speed of the forest fragmentation process, which triggers a sequence of imbalances throughout the environmental system, causing losses in the quality of the provision of Ecosystem Services (ES). In this sense, this research aims to evaluate the connectivity of vegetation cover in ESEC-Seridó and its buffer zone. For this purpose, LandSat 5 (TM sensor) and 8 (OLI sensor) satellite images from the years 1988, 1998, 2008 and 2019 were used to understand the temporal dynamics of vegetation cover, where 05 classes of vegetation cover were obtained: water, exposed soil, sparse vegetation, open vegetation and dense/riparian vegetation. it was found that the most representative class was open vegetation, with about 43% for the years 1988, 1998 and 2008, with sparse Caatinga being the most expressive in 2019 (29%). Subsequently, the degree of fragmentation of forest remnants was evaluated from landscape metrics into three categories: area, shape and edge. CBERS 4A satellite images (WPM sensor) were used, in which it was possible to identify the patterns of the fragments, as well as the most conserved and the most degraded. A total of 394 forest fragments were identified, 25% of which have values below 05 hectares and which tend to present greater characteristics of unstable environments. Next, the study area's capacity to provide erosion control ecosystem services through the Universal Soil Loss Equation (USLE) and carbon sequestration through the improved photochemical reflectance index was evaluated. It was identified that about 64% of the study area has a high relevant erosion control capacity, with the areas that do not have any relevant capacity representing around 6% of the total area. The carbon stock has a relevant capacity of 38%, being the highest value of the others. Finally, it is intended to obtain 03 scenarios of ecological corridors using the Fuzzy weighting logic in the variables of the previous chapters, modeling a stable, socioeconomic and strongly unstable environment scenario. It is concluded that the combination of different methodological procedures, such as Landscape Ecology, USLE and Ecosystem Services for measuring the degree of conservation and degradation of the environment become effective, since, from these approaches, different paths can be outlines for territorial planning and ordering, understanding the social, religious and cultural relations that shape semi-arid landscapes.
