As alterações climáticas (AC) constituem actualmente uma das maiores ameaças ambientais globais, com repercussões sociais e económicas para todo o planeta e humanidade. Os recursos hídricos, nomeadamente nas componentes de gestão da procura, do fornecimento e riscos infra-estruturais, são uma das áreas mais vulneráveis às AC. Este trabalho pretende ser um contributo para a gestão dos recursos hídricos em Portugal integrando a gestão do risco associado aos impactes das AC. Neste sentido, o trabalho inclui: i) a análise da variabilidade climática e da detecção das AC em Portugal; ii) a identificação do impacte de futuros cenários climáticos nos recursos hídricos e a identificação das maiores ameaças e fatores de risco; iii) a análise das estratégias de adaptação e sistemas de compensação existentes; iv) e a identificação de medidas adicionais a implementar em Portugal de modo a reduzir os riscos das AC na gestão da água.

Climate Change and Water Management in Portugal
ABSTRACT
Presently climate change (CC) is one of the greatest global environmental threats, with social and economic repercussions for the entire planet and humanity. Due to their vulnerability to CC, water resources are of major concern, particularly in the components of demand management, supply and infrastructure risks. This work intends to be a contribution for water resource management in Portugal, integrating risk management and climate change impacts. In this sense, this work includes: i) an analysis of climatic variability and climate change in Portugal; ii) an identification of the impacts of climate change scenarios in water resources and an identification of the major pressures and risk factors; iii) an analysis of the adaptation strategies and existing compensation systems; iv) and an identification of the additional measures to be implemented in Portugal, in order to reduce climate change impacts in water resources.
