SDG #6 is to “Ensure availability and sustainable management of water and sanitation for all”
Within SDG #6 are 8 targets, of which we here focus on Target 6.5:
By 2030, implement integrated water resources management at all levels, including through transboundary cooperation as appropriate
Target 6.5 has two indicators:
Indicator 6.5.1: Degree of integrated water resources management
Indicator 6.5.2: Proportion of transboundary basin area with an operational arrangement for water cooperation
What is integrated water resources management (IWRM)? In some ways, it’s reflective of the concept of sustainable development as it relates to water. It means to devise and put into effect a system which manages water resources with several considerations. It needs to consider the economic, social, and in particular the environmental aspects. At the governmental level, it can involve the coordination of several ministries. These might include the portfolios of water, planning, land, agriculture, and rural development.
Managing water resources is of utmost importance for the environment. But it also has large social, and economic implications in water scarce regions such as Western Asia and Africa. Every drop seems to count to ensure dignity and prosperity in these regions.
The Global Water Partnership, a network of over 3000 water organisations, and DHI, support such efforts. Managing water is relevant not only at the national level, but across countries within regions sharing a common border. It likewise has importance across administrative divisions within countries.
This issue of water resources shared across borders brings us to Indicator 6.5.2. This is relevant whether a shared water body is visible on the surface, or groundwater in an aquifer. This topic seems ripe for conflict in water scare regions, and as such, competing interests need managing. International treaties between nations on the sustainable use of transboundary freshwater aid this. The most prominent example is the 1997 Water Convention.
The degree to which an integrated water resources management plan is in effect across all countries worldwide is 54% as of 2020. France and Singapore lead with 100% implementation. A half-dozen countries score 0, among them Argentina, Canada, and Venezuela.
41% of global aquifers have transboundary basins with arrangements to cooperate over water as of 2022. 65% of river and lake basins have such coverage, with 58% for both combined.
