Blueprint framework para a Gestão Integrada dos Recursos Hídricos (GIRH): dashboard para a bacia do rio Tapajós

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO

O rio Tapajós é um dos maiores afluentes do rio Amazonas (na margem direita), atravessando quatro estados brasileiros. Sua complexidade se traduz nos diferentes aspectos fisiográficos constituintes, com a presença de áreas protegidas (terras indígenas e unidades de conservação) e regiões de forte potencial econômico (agrícola e mineral), configurando uma intensa pressão social nos seus municípios formadores. Em resposta a esse cenário, o objetivo desenvolvido foi descrever um cenário Blueprint Framework (BF), tomando como referência os municípios formadores e os principais fatores que afetam o desenvolvimento das cidades. O processamento consistiu: na elaboração do Quadro de Tendências e Pressões (TPF) e do Quadro de Desempenho do City Blueprint (CBF); na definição do Quadro de Capacidade de Governança (GCF); e na reclassificação conforme os principais agrupamentos. A base destes foram fontes públicas de dados, agrupadas nas dimensões social, ambiental e econômica. Os resultados enfatizaram que a bacia do rio Tapajós é uma região fragmentada e heterogênea, e as subbacias críticas são Jamanxin, Teles Pires e Juruena. Os indicadores municipais e o comportamento hídrico da bacia estabelecem uma divisão bem definida entre os cursos médio-alto e médio-baixo, aumentando a insegurança hídrica e indicando que ter disponibilidade de água na bacia hidrográfica não significa acesso social e econômico imediato ao recurso.
