This study aims to evaluate land cover changes in the Belén settlement, Ñeembucú Department, through a multi-temporal analysis for the period 1995–2022. The analysis identifies change trajectories, land cover transitions, persistence, gains and losses, and the internal structure of the forests. A quantitative approach with a longitudinal trend design is used, employing remote sensing techniques and Geographic Information Systems (GIS) for the analysis of Mapbiomas data. This methodology allows for the quantification of transitions, gains, losses, and persistence of different land cover classes. The results reveal a critical landscape transformation, characterized by a reduction in the dominant cover of floodplain grasslands. This loss is offset by an expansion of dry grasslands and an increase in floodplain woody vegetation, indicating a concurrent process of landscape dehumidification and ecological succession. The existence of direct anthropogenic pressure is evident, manifested in the deforestation of dense woodlands and the expansion of land use for production. It is concluded that the observed dynamics are driven by a combination of altered hydrological regimes and intensified land use, factors that compromise the sustainability of the ecosystem. This highlights the need to implement adaptive management strategies that include the conservation of remaining wetlands and the promotion of sustainable production systems.
