                         degradadas foram caracterizadas por apresentarem temperatura de 
                         superf{\'{\i}}cie mais elevada (37,5oC), tendo aumentado em 1oC 
                         no per{\'{\i}}odo de 2009 a 2016. O aumento da temperatura da 
                         superf{\'{\i}}cie pode estar associado ao estresse

                         the Land Use and Land Cover Changes in the desertification hotspot 
                         of Cabrob{\'o}-PE using an approach that includes the space-time 
                         variation of environmental and climate data. To achieve this goal, 
                         the ArcGis software and the Google Earth Engine Platform were 
                         used. This platform combines a catalog of satellite imagery and 
                         geospatial datasets with planetary-scale analysis capabilities and 
                         makes it available for scientists, researchers, and developers 
                         allowing the detection of changes, map trends, and quantify 
                         differences on the Earths surface. Results showed that forested 
                         areas decreased 54% between 2000 and 2016, being replaced by areas 
                         of bare soil and degraded areas. The degraded areas were 
                         characterized by higher land surface temperature (37.5% 
                         \⁰C) and by an increase of 1\⁰C in the period 2009 
                         to 2016. The increase in land surface temperature may be 
                         associated with the water stress, which usually worsens in areas 
                         with a high degree of soil degradation. The combination of the 
                         information analyzed in the present study allows the monitoring of 
                         heterogeneous areas, identifying hotspots that require immediate 
                         recovery actions and the improved of soil management.",
