The indicator at a glance

Indicator 6.5.2 tracks the percentage of transboundary basin area within a country that has an operational arrangement for 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.

For the arrangement to be considered operational, the following criteria need to be fulfilled:

  • Existence of a joint body
  • Regular, formal communication between riparian countries (at least once a year)
  • Joint or coordinated management plans or objectives
  • Regular exchange of data and information (at least once a year)

Data are commonly compiled by relevant national line ministries and institutions (e.g. for Water, Environment, Natural Resources, Hydrology, Geology).
