“…These provide compact and objective information to manage and develop policies. Index results can be widely understood and applied by public and private organizations, to achieve an adequate level of environmental sustainability [12,13]. Therefore, weighting and aggregating relevant sustainability indicators are necessary steps in any evaluation of sustainability indexes [14].…”

Integrating Environmental, Geographical and Social Data to Assess Sustainability in Hydrographic Basins: The ESI Approach

The elaboration of environmental sustainability indexes (ESI) aims to describe the complexity between social, environmental and ecological health. These indexes play a crucial role by helping stakeholders during the decision-making process and by identifying possible sites that require practical sustainable actions. In this study, we aim to elaborate an ESI for hydrographic basins. We use three factors to build the index: land use; vulnerability to soil degradation and topographic land attributes; and human development. The human development factor includes the dimensions of education, sanitation, longevity and income. These three factors are recommended by the Organization for Economic Cooperation and Development and reflect the pressure–state–impact assessment model. To verify the effectiveness of the proposed ESI, we applied it in a hydrographic basin located in southern Brazil. The sustainability level variation in the basin was classified into five groups: very low (0%), low (17%), intermediate (72%), high (11%) and very high (0%). The predominance of the intermediate sustainability level was found to mainly owe to the extent of agricultural land and the high degree of susceptibility to soil erosion in areas with low environmental conservation. In areas with native vegetation, environmental sustainability was found to be higher than in areas with other land use types. The resulting ESI will help facilitate future studies in environmental, economic or social dimensions in any hydrographic basin.

“…Many scienti c works employ approaches that make use of geotechnologies, such as geographic information systems and remote sensing, as an integrated tool for different types of geographic studies and methodologies (El Jazouli et al, 2017; Ambarwulan et al, 2021). Among these studies, different authors have used indicators and indexes as a tool for environmental analysis together with GIS, contributing with information on the state of degradation in water basins (Silva et al, 2022;Silva & Lima, 2017), and helping in the decision-making of public and private agencies.…”

Changes in land use have been occurring in a continuous and disorderly way in recent decades due to rapid population growth and the growing demand for food. These constant changes result in a series of deleterious effects to the environment, especially to water resources, signi cantly changing their availability and quality. This study aims to evaluate the degradation potential of watersheds through an evaluation of some environmental indicators using arithmetic means to construct an index called in this research "Index of Potential Environmental Degradation" (IPED). To form the IPED, the hydrographic subbasins of the Sorocabuçu River, located in the central west of the State of São Paulo, Brazil, comprised the study area. The results showed that most hydrographic sub-basins, that is, eight units, present degradation values ranging from moderate to very high, resulting mainly from low conservation values of forests plus a use destined to the planting of temporary cultures depending on good physical conditions.On the other hand, only one sub-basin showed a low degradation value. The methodology used for the development of the IPED is easy to apply and an effective tool for environmental analyses. It may contribute to studies and forms of planning and land use management aiming the conservation of water resources and protected areas and reduction of degradation.
