The Pantanal is one of the largest wetlands in the world. This natural region hasfundamental importance for water supply and biodiversity conservation. In thispaper, we apply a methodology to analyze multi-temporal water and vegetationchanges in six different zones of land use/land cover and their relationship withhumidity in the Brazilian Pantanal subregion of Cáceres, Mato Grosso. Meteorologicaldata 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 changesaccording to the occurrence of wet and dry years. In dry years there was a remarkableincrease in mean and maximum values linearly related to a decrease in water availability. Analyzing LULC change dynamics in these areas is crucial for developing newproposals for interventions to monitor the area and thus provide subsidies to goal 15 ofthe 2030 Sustainable Development Agenda, which aims to stop and restore degradation caused in the environment and to promote reforestation.
