Transboundary Water Management Along The Tagus River Basin In The Iberian Peninsula: Sustainable Water Allocation Of The Aqueduct Tagus-Segura

Spain and Portugal have established cooperation mechanisms to manage their shared water resources in order to avoid any potential conflict. Cooperation is clearly reflected in the 1998 Albufeira Convention, which provides a legal framework to regulate all transboundary basins between both countries to protect surface water and groundwater, as well as the aquatic and terrestrial ecosystems that depend on them for the sustainable use of water resources. The 1998 Albufeira Convention establishes as one of the uses of the Tagus Basin Gthe transfer of water interbasin such as the Aqueduct Tagus-Segura (ATS). According to this Convention, the management of water uses and the right to use water shall be addressed to guarantee the sustainable use of water that is already established. The ATS is a use guaranteed and protected under international water law. The analysis of the ATS in the context of the international legislation to mitigate water scarcity, and droughts provides the strategies to promote resilience to climate change and the impacts of drought conditions in the society in a sustainable manner while ensuring the fundamental rights.
