Abstract

Extreme weather events are characterized by meteorological conditions that significantly diverge from usual averages and can cause major impacts in both urban and rural areas. In the Upper Paraguay Basin (BAP), these events have been intensifying, affecting ecosystems such as the Pantanal and the Chaco. This study aimed to quantify disaster risk in the region using geotechnologies as a tool for impact mitigation and risk management. The methodology employed was based on the risk equation of Marcelino et al. (2006), which considers factors such as population density, poverty, dependent population, and the Human Development Index (HDI). The data were processed using QGIS software, and the results were classified into five risk levels, ranging from very low to very high. The results revealed significant differences among the states that make up the BAP. In Mato Grosso, 43% of municipalities presented a very low risk, while 4% were in the very high-risk range. In Mato Grosso do Sul, 24% of municipalities showed very low risk, and 6% were at very high risk. When analyzing the BAP as a whole, 31% of the municipalities were at very low risk, while 4% faced very high risk.
