Esta dissertação analisa a governança ambiental dos mouchões do estuário do Tejo, com enfoque nas tensões entre conservação ecológica, propriedade privada e interesse público. Assume-se de forma explícita a reflexividade do investigador e a possibilidade de viés decorrente da proximidade ao objeto de estudo, mitigada por estratégias metodológicas de triangulação, diversidade institucional e disciplinar no painel Delphi, critérios rigorosos na revisão sistemática da literatura e mecanismos de anonimato e feedback controlado. A pertinência do estudo assenta em quatro dimensões principais: social e política, marcada pela exclusão de proprietários e comunidades locais dos processos de decisão; territorial, com a prioridade dada a usos urbanos e logísticos que comprimem ecótonos e fragilizam zonas ribeirinhas; agrícola e económica, evidenciada pela reconversão produtiva recente e pelos impactos da globalização; e científica e ecológica, sublinhada pela elevada biodiversidade do estuário e pela vulnerabilidade acrescida às alterações climáticas. A investigação foi orientada pela questão de saber se a governança pode adaptar se às pressões antropogénicas e naturais que incidem sobre os mouchões sem comprometer os valores ecológicos da área protegida e, em simultâneo, responder aos interesses privados. O objetivo geral consistiu em avaliar de que forma a governança vigente na Reserva Natural do Estuário do Tejo influencia a gestão e a adaptação dos mouchões perante mudanças ambientais e institucionais, desdobrando-se em objetivos específicos relacionados com a identificação de atores e políticas públicas, a caracterização de mudanças ambientais, e a avaliação da capacidade adaptativa.
This dissertation analyzes the environmental governance of the islands in the Tagus estuary, focusing on the tensions between ecological conservation, private property, and public interest. It explicitly acknowledges the researcher's reflexivity and the possibility of bias arising from proximity to the object of study, mitigated by methodological strategies of triangulation, institutional and disciplinary diversity in the Delphi panel, rigorous criteria in the systematic review of the literature, and mechanisms of anonymity and controlled feedback. The relevance of the study is based on four main dimensions: social and political, marked by the exclusion of local owners and communities from decision-making processes; territorial, with priority given to urban and logistical uses that compress ecotones and weaken riparian areas; agricultural and economic, evidenced by recent productive reconversion and the impacts of globalization; and scientific and ecological, underlined by the high biodiversity of the estuary and its increased vulnerability to climate change. The research was guided by the question of whether governance can adapt to anthropogenic and natural pressures on the mouchões without compromising the ecological values of the protected area and, at the same time, responding to private interests. The overall objective was to assess how the current governance of the Tagus Estuary Nature Reserve influences the management and adaptation of the mouchões in the face of environmental and institutional changes, breaking down into specific objectives related to the identification of actors and public policies, the characterization of environmental changes, and the assessment of adaptive capacity.
