obtidas as respostas da vegeta{\c{c}}{\~a}o em raz{\~a}o da

and Caatinga biomes present great vulnerability in terms of
conservation and degradation. The degradation of these biomes has
been increasingly present, bringing risks and probable indications
of desertification and even extinction of ecosystems and existing
biodiversity. Thus, the present work had the purpose to analyze
proxies of degradation of these biomes. For this purpose, specific
points were selected from the two biomes that showed classes of
natural vegetation and pasture that remained over 18 years. At
these points were obtained the vegetation response due to
precipitation and surface temperature over that period. Orbital
data (EVI, LST and TMPA) and meteorological stations were used to
run correlation and dispersion graphs between the variables under
study. There were unbalanced points between vegetative indexes /
precipitation, precipitation / temperature and between vegetative
indexes / temperature, indicating proxies of degradation.",
