Portuguese–Spanish river basins: bilateral agreements' evolution and context
The main aim of the Portuguese–Spanish active bilateral international rivers Conventions (1964 and 1968) was to rule on the sharing of water and hydroelectric potential production of bordering river stretches. The new “Convention on Cooperation for Portuguese–Spanish River Basins Protection and Sustainable Use”, signed by the two governments but still to be ratified, envisages co-ordinating efforts on shared river basins management, aiming to attain improved risk prevention and ecosystem protection on those basins, respecting modern principles of international law. An analysis of the new Portuguese–Spanish Convention will be presented, bearing in mind international and European Union law and principles, namely the European Union Water Framework Directive Proposal. Different issues such as water resources development, protection and management of the Portuguese–Spanish river basins, including an envisaged flow regime definition, will be analysed, always according to the legal and political paradigms.
