O método AHP e a Álgebra de Mapas para determinar a fragilidade ambiental da bacia hidrográfica do Rio Brilhante (Mato Grosso do Sul / Brasil), proposições para a gestão do território

Abstract: A determinação da fragilidade emergente ou ambiental de uma bacia hidrográfica é fundamental para avaliar como as características físicas e as interferências antrópicas podem influenciar no estado de equilíbrio do sistema. Este trabalho apresenta um modelo para estabelecer classes de fragilidade ambiental a partir da sobreposição de fatores naturais e antrópicos, combinando o método de análise hierárquica (AHP) e a Álgebra de Mapas, hierarquicamente integrados em ambiente SIG, isso a fim de contribuir com a ge… Show more

“…The application of MCDM methods for complex geospatial scientific investigations, as in the context of epidemiological surveillance, has been widely used in the literature (Malczewski & Rinner, 2015;Ferreira & Silva, 2020;Niño et al, 2020;Lopes et al, 2022, November). Chabuk et al, (2017) use the AHP method to define the hierarchical importance of physical and environmental factors that contribute to the potential environmental fragility assessment of the river basin of the Jequitinhonha River Basin, Minas Gerais, Brazil.…”

“…Many works in the literature address the use of multi-criteria decision-making methods (MCDM), such as the Analytical Hierarchy Process (AHP), to overcome this challenge. In Ferreira and Silva (2020) the authors use the Analytical Hierarchy Process (AHP) method with Map Algebra to determine the environmental fragility of the Rio Brilhante watershed in Mato Grosso do Sul, Brazil, from the superposition of natural and anthropic factors. The authors use the AHP method to define a set of weights with the level of importance among the variables with the most significant influence on the definition of the environmental fragility of the basin from the paired analysis by an expert.…”

“…The riparian forest performs important services such as atmospheric carbon retention, nutrient cycling, stabilization and influence on soil composition, in addition to offering subsistence conditions for fauna such as food and shelter (PEQUENO et al, 2002). The importance of this vegetation intensifies in regions with a higher incidence of anthropogenic activities (FERREIRA;SILVA, 2020;PEQUENO et al, 2002).…”
