“…This causes the soil in these areas to reach higher average temperatures because it receives a greater load of solar radiation, consequently increasing the areas with heat stains by at least 6 °C between the days of the selected images (Table 8). Lins et al (2017) pointed out that in studies aimed at the evaluation of biophysical parameters, in question at surface temperature, higher values are usually expected on exposed soil areas or urban areas, where they observed an increase in temperature, on average, of 3,34 °C when passing from regions with abundant vegetation to areas of exposed soil, and values in the urban area (33.94 and 35.75 °C) that corroborate with the present research.…”

“…In the last decades, geotechnology has been prominent in the geotechnologies development and has opened a new area of action for environmental monitoring of semi-arid regions from Brazil and the world, in particular the technologies involved in the detection of spectral responses in airborne and orbital sensors, part of the scope of remote sensing. Among the most used applications in this segment, the studies on detection, analysis and monitoring of the Caatinga biome vegetation cover stand out (Silva & Galvíncio, 2012;Vieira et al, 2013;Bezerra et al, 2014;Vieira et al, 2015;Lins et al, 2017;Oliveira et al, 2017;Barbosa et al, 2018;Campos et al, 2019).…”

“…In particular, the Soil Adjusted Vegetation Index (SAVI), a biophysical parameter that seeks to attenuate the previous effects of the soil, correcting it by the adjustment factor limitations imposed by other indexes in the semi-arid; and also the leaf area index (LAI), important in highlighting in Caatinga vegetation the highest/lowest photosynthetic activity, thus indicating the quality of plant biomass. Based on this information, it is possible proposing appropriate management and guiding the exploitation of plant resources (Allen et al, 2007;Silva & Galvíncio, 2012;Ribeiro et al, 2016;Leite et al, 2017;Lins et al, 2017;Oliveira et al, 2017).…”

“…A vegetação predominante da região é basicamente composta por Caatinga Hiperxerófila com trechos de Floresta Caducifólia (Beltrão et al, 2005 Através dos dados de chuva coletados para o período de 1986 a 2017, aplicou-se a técnica dos Quantis para escala temporal anual proposta por Pinkayan (1966) e introduzida no Brasil conforme Xavier e Xavier (1999). A finalidade foi classificar as precipitações anuais em classes (muito seco, seco, normal, chuvoso e muito chuvoso), com as respectivas ordens quantílicas, probabilidades = 0,15; 0,35; 0,50; 0,65 e 0,85 (Lins et al, 2017 O processamento digital foi realizado através do Software ERDAS IMAGINE ® 9.1, utilizado principalmente em processos como, empilhamento de bandas multiespectrais e o georreferenciamento perante o Sistema de Projeção Cartográfica UTM (Universal Transversa Mercator) DATUM: WGS84, zona 24 M, na qual encontra-se a área de estudo.…”

“…Devido à ausência de vegetação, os valores elevaram-se de 43,97 a 51,90 °C (pixels vermelhos), diversas áreas nos mapas temáticos apresentam-se com padrões de comportamento similares, áreas que merecem preocupação constante e monitoramento adequado, principalmente nas épocas secas quando os processos de degradação e desertificação se intensificam no semiárido brasileiro, sendo à agricultura irrigada nessas épocas potencializadoras da degradação, pela intensidade dos manejos e alto consumo hídrico. Lins et al (2017), avaliando parâmetros biofísicos no semiárido brasileiro, ressaltaram que ao passar de regiões com cobertura vegetal em abundância para áreas de solo exposto, a temperatura da superfície tem grande elevação de até 3,34 °C.…”
