Abstract

This investigation evaluates the bioclimatic vulnerability of the floodplain at the confluence of the Guamá River, in the state of Pará, to hydroclimatic changes and local human-induced pressures. The aim was to evaluate the level of bioclimatic sensitivity in this area.Time-series analyses (2003–2023) of precipitation, temperature and evapotranspiration were combined with decadal water balance and land use/land cover mapping. The results revealed significant interannual variability in precipitation, critical seasonal water deficits and the expansion of urban areas within and around the Environmental Protection Areas (EPAs Belém and Ilha do Combu), which has intensified the loss of vegetation cover and put pressure on water resources. Spatial analysis revealed a correlation between low evapotranspiration and urbanized areas, reflecting a loss of ecological functionality. It is concluded that territorial planning must incorporate nature-based solutions and participatory management, prioritizing climate adaptation measures and the ecological preservation of the region's urban wetlands.
