 This study examined the effects of drought on the Catinga vegetation in the semi-arid region of Pernambuco, Brazil. It used satellite imagery to measure changes in albedo, surface temperature, NDVI, SUVI, and LAI over time. The results showed that during the dry season, the Catinga vegetation had a higher tendency towards environmental degradation due to its reduced leaf area.
