Gestão integral da segurança hídrica: diagnóstico, desafios e alternativas multissetoriais para o uso sustentável do recurso
Palavras-chave:
Segurança hídrica, gestão multissetorial, escassez hídrica, governança sustentávelResumo
A pesquisa teve como objetivo analisar a situação hídrica no departamento de Ica (Peru), identificando os fatores que agravam a escassez hídrica e propondo estratégias integradas de gestão sustentável. Utilizou-se uma abordagem mista, combinando métodos qualitativos e quantitativos: entrevistas semiestruturadas com autoridades, especialistas e usuários, além de pesquisas realizadas com 295 pessoas de áreas urbanas e rurais. O estudo revelou que a escassez hídrica em Ica constitui um problema estrutural agravado pela superexploração de aquíferos, infraestrutura hídrica precária e coordenação institucional limitada. As partes interessadas concordaram com a necessidade urgente de promover soluções conjuntas, como recarga artificial de aquíferos, reuso de águas residuais, controle de poços ilegais e modernização de canais de irrigação. Concluiu-se que a segurança hídrica em Ica requer governança participativa e multissetorial, onde o Estado, as empresas e a sociedade civil compartilham responsabilidades para garantir o acesso equitativo e sustentável à água diante dos efeitos das mudanças climáticas.
