Resumo: | The need for efficient water resources management highlights the importance of discussing the watershed sustainability issue. This is a complex subject, which justifies the choice for multidimensional indexes. The aim of this paper is to discuss the assessment of watersheds’ sustainability through composite indices to detect this statistical instrument’s strengths and weaknesses. This is a descriptive, exploratory, and quantitative research. The literature review on sustainability indices and their application in hydrographic basins guided the selection of a watershed sustainability index (WSI). The dual approach that combines the criteria of the Pressure-State-Response (PER) model with the dimensions of the Hydrology-Environment-Life-Policy model (UNESCO HELP model) guided the selection of the fifteen indicators that were chosen. The WSI was used to assess the degree of sustainability of the Piracicaba, Capivari and Jundiaí river basins during two periods in the 2010s. The analysis of the results detected a minor decrease in the index’s value, due to the Hydrology and Politics dimensions that recorded a setback in the second half of the decade under analysis. The result was not worse because of the remarkable improvement recorded in the Life dimension. This compensation is a weakness of the WSI that implicitly promotes the concept of weak sustainability. On the other hand, the selection of indicators guided by the dual approach is particularly interesting and challenging by connecting the PER criteria with the dimensions of sustainability well summarized in the HELP model. |

Ao mesmo tempo, a complexidade do assunto justifica a escolha de indicadores sintéticos multidimensionais. O objetivo do artigo é discutir a avaliação da sustentabilidade de bacias hidrográficas por meio de índices compostos visando identificar pontos fortes e fracos desse instrumento estatístico. Trata-se de uma pesquisa exploratória, descritiva, aplicada e com abordagem quantitativa. Por meio de uma revisão da literatura dos índices de sustentabilidade e de sua aplicação em bacias hidrográficas, foi selecionado um índice da sustentabilidade de bacias hidrográficas (WSI). A escolha dos quinze indicadores que o compõem foi orientada por uma dupla abordagem que associa os critérios do modelo Pressão-Estado-Resposta (PER) às dimensões do modelo Hidrologia-Ambiente-Vida-Política (Hidrology-Environment-Life-Policy ou modelo HELP da Unesco). O WSI foi aplicado para avaliar o grau de sustentabilidade das bacias dos rios Piracicaba, Capivari e Jundiaí, em dois intervalos da década de 2010. A análise dos resultados permite observar uma leve redução do valor do índice, imputável às dimensões Hidrologia e Política que registraram um retrocesso na segunda metade da década em análise. O resultado não foi pior pelo notável avanço registrado na dimensão Vida. Esta compensação de variações é um exemplo de fraqueza do índice que implicitamente se baseia no conceito de sustentabilidade fraca. Por outro lado, a seleção de indicadores orientados pela dupla abordagem demonstra-se particularmente interessante e desafiadora na busca de associar os critérios PER às dimensões da sustentabilidade bem resumidas no modelo HELP.Universidade Federal de Uberlândia2022-05-02info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/6386810.14393/SN-v34-2022-63868Sociedade & Natureza; Vol. 34 No. 1 (2022): Sociedade & Natureza; v. 34 n. 1 (2022): 1982-45130103-1570reponame:Sociedade & natureza (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUengporhttps://seer.ufu.br/index.php/sociedadenatureza/article/view/63868/33815https://seer.ufu.br/index.php/sociedadenatureza/article/view/63868/33816Copyright (c) 2021 Bruna Angela Branchihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessBranchi, Bruna Angela2023-04-06T20:32:29Zoai:ojs.www.seer.ufu.br:article/63868Revistahttp://www.sociedadenatureza.ig.ufu.br/PUBhttps://seer.ufu.br/index.php/sociedadenatureza/oai||sociedade.natureza.ufu@gmail.com|| lucianamelo@ufu.br1982-45130103-1570opendoar:2023-04-06T20:32:29Sociedade & natureza (Online) - Universidade Federal de Uberlândia (UFU)false |
