DueroTagus

DueroTagus is the name given to the shared river basin of the Douro and Tagus rivers. These are two of the most significant rivers in the Iberian Peninsula, originating in Spain and flowing westward into Portugal before emptying into the Atlantic Ocean. The Duero, known as the Douro in Portugal, is the third longest river in the Iberian Peninsula, while the Tagus is the longest. Their extensive drainage basins cover a substantial portion of central and western Iberia, encompassing a diverse range of landscapes from mountainous terrain to fertile plains.

The DueroTagus basin is characterized by its varied hydrology, influenced by climatic conditions that range from semi-arid in the east to more oceanic in the west. This has historically shaped agricultural practices, with wine production being particularly prominent in certain regions of the basin, such as the Douro Valley in Portugal. The rivers have also played a crucial role in transportation and trade throughout history, with cities and settlements developing along their banks.

Ecologically, the DueroTagus basin supports a rich biodiversity. The rivers and their tributaries are home to various aquatic species, and the surrounding areas provide habitats for a wide array of flora and fauna. Management of the basin's water resources is a significant concern, involving both Spain and Portugal due to the transboundary nature of the rivers. Issues such as water allocation, pollution control, and the impact of climate change are ongoing considerations for the sustainable use and preservation of this vital Iberian hydrographic system.
