The Pantanal is one of the largest wetlands in the world. This natural region has fundamental importance for water supply and biodiversity conservation. In this paper, we apply a methodology to analyze multi-temporal water and vegetation changes in six different zones of land use/land cover and their relationship with humidity in the Brazilian Pantanal subregion of Cáceres, Mato Grosso. Meteorological data from the INMET Station in Cáceres was used. The Normalized Difference Vegetation Index (NDVI) and Normalized Difference Moisture Index (NDMI) were compared year to year (2019, 2020, 2021). The spatial variations revealed water changes according to the occurrence of wet and dry years. In dry years there was a remarkable increase in mean and maximum values linearly related to a decrease in water availability. Analyzing LULC change dynamics in these areas is crucial for developing new proposals for interventions to monitor the area and thus provide subsidies to goal 15 of the 2030 Sustainable Development Agenda, which aims to stop and restore degradation caused in the environment and to promote reforestation.
