Indicator 6.5.2 – Transboundary water cooperation

An “arrangement for water cooperation” is a bilateral or multilateral treaty, convention, agreement or other formal arrangement between riparian countries that provides a framework for cooperation on transboundary water management. Criteria for an “operational” arrangement are: the existence of a joint body, regular, formal communication between riparian countries, joint or coordinated management plans or objectives and a regular exchange of data and information.

  • 59 % of transboundary basin area has an operational arrangement for water cooperation (SDG indicator 6.5.2), based on reporting in 2017 from 61 countries (or areas)

Global status of Indicator 6.5.2 Proportion of transboundary basin area with an operational arrangement for water cooperation (%) (2017)

The overall indicator value (for both river and lake basins and aquifers) is available for 62 countries, which corresponds to 41 % of the 153 countries that share transboundary basins. The world map shows the global status of Indicator 6.5.2. The 62 countries are spread over several regions, although some regions are better represented than others: 56 % of countries sharing transboundary basins in Northern America and Europe; 50 % for Latin America and the Caribbean; 47 % for sub-Saharan Africa; 33 % for Northern Africa and Western Asia; 28 % for Central and Southern Asia; and 8 % for Eastern and South-Eastern Asia. Only 17 countries have all their transboundary basins covered by operational arrangements, and 12 of the countries that reported have no operational arrangements in place.

Status in different countries (or areas) on Indicator 6.5.2 Proportion of transboundary basin area with an operational arrangement for water cooperation (%) (2017)

The chart provides a breakdown of indicator 6.5.2 across all countries where the value is available. This highlights that only 17 of the reporting countries have all their transboundary basin area covered by an operational arrangement – most of these countries are located in North America and Europe.

  • Australia and New Zealand
  • Eastern and South-Eastern Asia
  • Central and Southern Asia
  • Latin America and the Caribbean
  • Europe and Northern America
  • Sub-Saharan Africa

Status on different components of Indicator 6.5.2 Proportion of transboundary basin area with an operational arrangement for water cooperation (%) (2017)

Proportion of transboundary basin area with an operational arrangement for water cooperation, by water body type: transboundary river and lake basins and transboundary aquifers.

Overall (based on 62 countries): While data are available for transboundary aquifers in 64 countries, and for river and lake basins in 87 countries, the overall indicator is only available for 62 countries because in 25 instances it was not possible to calculate either the value for river and lake basins or for transboundary aquifers.

River and lake basins (based on 84 countries) - While data are available for 87 countries sharing transboundary aquifers, three countries state that they do not share transboundary rivers and lakes. Only data on 84 countries are therefore presented.

Aquifers (based on 61 countries) - While data are available for 64 countries sharing transboundary aquifers, three countries state that they do not share transboundary aquifer resources.Only data on 61 countries is therefore presented.
