Environmental fragility of Iguaçu river watershed, Paraná, Brazil

Abstract: SUMMARYThe aim of this study was to analyze the environmental fragility of Iguaçu River watershed, Paraná. Regarding fragility potential, most watersheds fell under the moderate fragility class (40.47 % of the total), followed by very low (18.83 %), low (16.20 %), high (13.27 %) and very high with only 8.68 %. Concerning emerging fragility, most watersheds again lay within moderate fragility (41.55 %), though in this case low fragility was found in second place (with 40.73 %), followed by very low (7.67 %), hi… Show more

“…The Iguaçu River rises in the Serra do Mar and flows through a geological fault throughout Paraná State (Maack, 1981). The hydrographic basin covers the Paraná and the Santa Catarina states in Brazil and the Misiones region in Argentina (Dalla Corte et al, 2015). The study area comprised the Low Iguaçu River and its main tributaries in the stretch between the Salto Caxias dam and the Santo Antônio River mouth (Iguaçu National Park), where 25 sampling sites were established (the first sampling site: 25°35'17.04"S-53°29'56.58"W; the last sampling site: 25°35'17.16"S-53°59'25.20"W; Fig.…”

“…As bacias hidrográficas urbanas brasileiras, em sua maioria sofreram com a falta de um delineamento capaz de preservar fatores do meio ambiente importantes, contribuindo assim para o aumento da fragilidade ambiental e escassez de recursos (Teixeira et al, 2009). Os impactos causados pela exploração dos recursos naturais, variam conforme o grau de resistência a modificações que cada ambiente possui, assim, a vulnerabilidade ambiental pode variar em função das características do meio (Dalla-Corte et al, 2015).…”
