Integrated river and lake management is organized into international commissions for entire river basins in the case of transboundary waters. The commissions’ activities are based on international agreements. Part of the Basque Country is located in the Garonne-Cantabrian-Ebro international river basin. In February 2006, a cooperation agreement was signed in Toulouse to coordinate, as effectively as possible, the measures taken in the river basins located on both sides of the border, in implementation of the Water Framework Directive (WFD), as well as to establish regular administrative cooperation.

Available indicator

Proportion of the area of ​​transboundary basins subject to operational arrangements for water cooperation
Target

6.5 By 2030, implement integrated water resources management at all levels, including through transboundary cooperation as appropriate
Goal

6- Ensure availability and sustainable management of water and sanitation for all
Definition

Proportion of transboundary basin area with an operational arrangement for water cooperation
Theoretical formula \[PSTCOOP^{t} = \frac{STCOOP^{t}}{ST^{t}} \cdot 100\]

where:

$STCOOP^{t} =$ transboundary basin area covered by an operational arrangement for water in the year $t$

$ST^{t} =$ transboundary basin area in the year $t$

This section provides more information about the United Nations indicator or the European Union Sustainable Development Indicator, such as its rationale, international results, metadata, and other relevant statistics.

Rationale

The majority of the world’s water resources are shared: 468 transboundary aquifers have been identified in 2021 and 310 transboundary lake and river basins cover nearly one half of the Earth’s land surface and account for an estimated 60% of global freshwater. Approximately 40% of the world’s population lives in river and lake basins shared by two or more countries and over 90% lives in countries that share basins.

Development of water resources has impacts across transboundary basins, potentially on countries sharing transboundary basins, and use of surface water or groundwater may affect the other resource, which are often interlinked. Intensive water use, flow regulation or pollution risks going as far as compromising the development aspirations of countries sharing transboundary basins and therefore transboundary cooperation is required. However, cooperation is in many cases not advanced.
