Transboundary aquifers in SDG indicator 6.5.2 calculation
• Integration of Aquifer Surface areas in calculating indicator value:
• No “overall” value for the indicator, if aquifer component is lacking.
6.5.2 indicator value =
refers to Aquifers
refers to Aquifersrefers to river& lake basins
refers to river& lake basins
When an ‘operational arrangement’ covers an aquifer?
Option 1 "Direct coverage": 4 operationality criteria applicable for the aquifer.
Option 2 "Through the river basin":
groundwater mentinoed in arrangement or groundwater activities
+ 4 criteria applicable to the basin
=possibility to tackle issues regarding transboudary aquifers
Different columns to fill in Section 1 “Table for aquifers” (essential for validation)
Common mistakes (relative to Option 2)
!!! Aquifers identified as been integrated in a river basin, but not the case after verification;
!!! Only part of the aquifer overlaps the river basin but aquifer area fully accounted.
• Surface area (in km2): projection of aquifer ‘3D shape’ on land surface
• Case of superimposed aquifer systems: multiple counting
• Not always easy to determine if aquifer systems are inter-related or not: country decision
when lack of knowledge
• Only for the part of the aquifer that is within the territory of the country
• Main challenge: data on delineation of the limit of the aquifer system
Surface area of aquifer to be included
• Priority: National coordination (Geological surveys, etc.)
• Global database:
• In general: Experts officially appointed by the Member States
• Last initiative: GEF Transboundary Waters Assessment Programme Information System(Executed by UNESCO)
• UNESCO IHP: Internationally Shared Aquifer Resources Management
• Collaboration with other regional centers and institutions, such as:
• SDG process: an opportunity to refresh the information
Data availability on Transboundary aquifers

A progressive and adaptable process
• Baseline: many countries lack data on transboundary aquifer or no consolidated data
• A first estimation can be based on rough delineation and improved later
• Adaptable process regarding some uncertainties:
delineation, connected systems, area of transboundary influence, etc.
- Opportunity to strengthen national coordination, cooperation and data sharing;
- Impact in terms of visibility and increased awareness of national and cross-border issues;
- Wealth of data that had never been transmitted before.
Also important for:
• A/RES/74/193 UNGA 2019 Resolution – “the Law of transboundary aquifers”
• management of surface water and groundwater

operational arrangement
for water cooperation
What is an ‘operational arrangement’?
• A joint body or mechanism (e.g. a river basin organization) for transboundary cooperation exists;
• Regular (at least once per year) formal communications between riparian States
• Joint or coordinated water management vision/plan(s), or similar instrument in place
• Regular exchange (at least once per year) of data and information
