Resumo: | The environmental vulnerability index is a vital tool in the investigation and identification of factors which may generate environmental degradation in ecosystems, such as the watersheds. In view of what has been exposed here, the objective of this study was to determine the environmental vulnerability index in the micro-watershed of Talhado, in the municipality of Santa Luzia, Paraíba. For the application of the methodology, the environmental vulnerability index was generated by the addition of the following information plans: normalized difference vegetation index, topographical factor, current land use, permanent preservation areas and restricted use; which were created using a geographical information system, which encompassed Idrisi Andes, version 16.0. The results showed that 581.2 hectares (49.9%) of the micro-watershed were identified with moderate vulnerability, followed by areas of 541.4 hectares (46.5%) with low and very low vulnerabilities, while 41.1 hectares (3.5%) varied from serious to very serious. These results indicate that special attention must be given to the conservationist management of its natural resources on Talhado’s micro-watershed. |

Diante do exposto, o objetivo deste estudo foi determinar o Índice de Vulnerabilidade Ambiental na microbacia hidrográfica do Talhado, localizada no município de Santa Luzia, Paraíba. Para aplicação da metodologia, o Índice de Vulnerabilidade Ambiental foi gerado pela soma dos seguintes planos de informações: índice de vegetação por diferença normalizada, fator topográfico, uso atual da terra e áreas de preservação permanente e uso restrito. Estes planos foram criados utilizando um sistema de informações geográficas que utilizou o Idrisi Andes, versão 16.0. Os resultados mostraram que 581,2 hectares (49,9%) da microbacia foram identificados com vulnerabilidade moderada, seguida pelas áreas com vulnerabilidades baixa e muito baixa com 541,4 hectares (46,5%), enquanto que 41,1 hectares (3,5%) apresentaram vulnerabilidade que variaram de grave a muito grave. Tais resultados indicam atenção especial que deve ser dada ao manejo conservacionista dos recursos naturais na Microbacia do Talhado, Paraíba.Universidade Federal de Campina Grande - UFCG2017-09-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/4710.22571/Actabra13201747Acta Brasiliensis; Vol 1 No 3 (2017): Acta Brasiliensis; 8-16Acta Brasiliensis; Vol 1 No 3 (2017): Acta Brasiliensis; 8-16Acta Brasiliensis; Vol 1 No 3 (2017): Acta Brasiliensis; 8-162526-43382526-432Xreponame:Acta Brasiliensis (Online)instname:Universidade Federal de Campina Grande (UFCG)instacron:UFCGporhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/article/view/47/22Copyright (c) 2017 Acta Brasiliensisinfo:eu-repo/semantics/openAccessAssis, Fellipe Ragner VicenteLima, Joedla Rodrigues deSilva, José Evanaldo RangelMendonça, Izaque Francisco Candeia2021-07-12T20:04:18Zoai:ActaBra.revistas.ufcg.edu.br:article/47Revistahttp://revistas.ufcg.edu.br/ActaBraPUBhttp://revistas.ufcg.edu.br/ActaBra/index.php/actabra/oaiactabrasiliensis@gmail.com || actabrasiliensis@gmail.com2526-432X2526-4338opendoar:2021-07-12T20:04:18Acta Brasiliensis (Online) - Universidade Federal de Campina Grande (UFCG)false |
