RESUMO:

The population increase has been impacting the natural environment, and this is due to the changes in the coverage and use of the land and, consequently, the biophysical parameters of the surfaces that characterize the energy and thermal equilibrium of the soil. Land use contributes to possible climate change, as human activities influence climate change by altering the distribution of ecosystems. The Potiguar Basin, located in the Borborema Province in the states of Rio Grande do Norte and Ceará, is characterized by being the largest oil producer, on land, and third in the sea, in Brazil, as well as for having great saline and subsistence activities. In this way, the research aims to associate changes in land use and occupation with climatic variability and desertification in the Potiguar Basin. For this, satellite imagery will be used for remote sensing (SR) treatment. In addition, the climatic data of rainfall, air temperature and reference evapotranspiration available by Xavier et al. (2017). In the first set, SR and climatic data will be used to obtain indices capable of being related to being able to identify, classify and evaluate desertification in the study area. At this point, it will be possible to evaluate the change in land cover and desertification in the Potiguar Basin from variables such as Normalized Difference Vegetation Index and albedo using the levels of desertification classification and the decision tree. Subsequently, a trend analysis on precipitation and air temperature variables will be performed from the extreme climatic indexes as the objective of evaluating the possible impacts of climatic variability on BP. As a result, it is expected that it will be possible to identify the evolution in the degree of desertification in the basin and the regional changes in precipitation and temperature indices.
