Resumo(s)
O Empreendimento de Fins Múltiplos de Alqueva foi, durante muitos anos, a esperança
para a população do Alentejo como motor dinamizador da economia e instrumento capaz de
inverter o ciclo de estagnação e despovoamento bem como da escassez hídrica que marcaram
a região durante décadas. Concebido como um projeto de regadio de grande escala, o
empreendimento evoluiu para uma infra-estrutura multifuncional, nomeadamente uma
reserva estratégica de água. Passados 25 anos desde o augue da obra da barragem, o presente
estudo visa avaliar em que medida as promessas de desenvolvimento e sustentabilidade
associadas ao empreendimento foram concretizadas aos mais diferentes níveis. A investigação
segue uma abordagem metodológica mista, combinando a análise quantitativa de indicadores
de desenvolvimento sócio-economicos e ambientais com a análise qualitativa de relatórios
institucionais e literatura científica, com base em dados da Empresa de Desenvolvimento e
Infra-estuturas do Alqueva e do Instituto Nacional de Estatística. Os resultados evidenciam o
contributo do empreendimento para a modernização agrícola, através da expansão da área
irrigada e da diversificação produtiva. Contudo persistem desafios estruturais, como o
envelhecimento populacional, a perda demográfica e a pressão ambiental associada à
intensificação agrícola, bem como os conflitos relacionados com a qualidade da água, a
degradação dos solos e a escassez de ferramentas eficazes de gestão e monitorização na
matéria de água e biodiversidade. Apesar do contributo do empreendimento para o
dinamismo económico as expectativas iniciais não se concretizaram na plenitude: os
indicadores de qualidade de vida da população residente não se alteraram de forma
significativa. Desta forma, conclui-se que o empreendimento constitui uma infra-estrutura
estratégica para o Alentejo, tendo contribuído para o dinamismo económico. No entanto
persistem incertezas e desafios, a nível do uso sustentável do território e do modelo de
desenvolvimento local.
For many years, the Alqueva Multipurpose Project was the hope of the Alentejo population as a driving force for the economy and an instrument capable of reversing the cycle of stagnation and depopulation, as well as the water scarcity that had marked the region for decades. Conceived as a large-scale irrigation project, the development evolved into a multifunctional infrastructure, namely a strategic water reserve. Twenty-five years after the dam was completed, this study aims to assess the extent to which the promises of development and sustainability associated with the project have been fulfilled at various levels. The research follows a mixed methodological approach, combining quantitative analysis of socio-economic and environmental development indicators with qualitative analysis of institutional reports and scientific literature, based on data from the Alqueva Development and Infrastructure Company and the National Statistics Institute. The results highlight the project's contribution to agricultural modernisation through the expansion of irrigated areas and production diversification. However, structural challenges remain, such as population ageing, demographic loss and environmental pressure associated with agricultural intensification, as well as conflicts related to water quality, soil degradation and the lack of effective water and biodiversity management and monitoring tools. Despite the project's contribution to economic growth, initial expectations were not fully met: indicators of quality of life for the resident population did not change significantly. It can therefore be concluded that the project constitutes a strategic infrastructure for the Alentejo region and has contributed to economic growth. However, uncertainties and challenges remain in terms of sustainable land use and the local development model.
