Project summary

Edit project overview to modify the project summary.

The Guadiana basin is one of the three major river basins shared between Portugal and Spain and the one that currently has more problems both in quantity and water quality. This is partly justified by the marked seasonality of precipitation, a strong inter-annual irregularity, and the predominance of drier weather conditions. This scarcity justified a strong regularization and use of available resources, which, however, created more pressure on the river systems due to increasing demand. In the current context of climate change, this picture tends to worsen, with the main scenarios pointing to a significant reduction in water availability. In the southernmost part of the basin, where the river is bordered by the two countries, high climate vulnerability ineracts with significant water uses (irrigation, coastal tourism, urban supply), degradation problems and poor water quality, as well as important ecological and natural values classified by the Natura 2000 Network and representing transboundary spaces of great environmental value in the Iberian Peninsula. The Valagua project addresses these issues, in a cooperation effort of Portugal and Spain, with the main goal of fostering research, knowledge, exchange and harmonization of information, as well as the implementation of good water and associated habitat management practices. The project main actions are: • Production of knowledge on water quantity and quality, water use to safeguard habitats, and resolution of associated use conflicts. • Implementation of functional and demonstrative actions for ecological restoration of riverine and riverine habitats, and awarenes raising in specific target groups to promote sustainable solutions. • Creation of new ecotourism products, specific enhancement interventions, tour operators training and exchange of experiences. • Development of integrated proposals for transboundary water and biodiversity management and their dissemination to policy makers, managers and other stakeholders.
