The Pretashkent Transboundary Aquifer case-study

Scope of the project- global & regional -

TWAP Case studiesPretashkent / Stampriet / Trifinio

Global Scope

1) level 1 assessment to assist the GEF and other international organisations to prioritise activities

2) formalise partnerships with key institutions resulting in periodic assessments.

1)set three examples of detailed level 2 assessment to complement the level 1 assessment of TWAP (global pilot)

Regional scope

N.A. 1)enhance regional knowledge and improve water cooperation and overall environmental sustainability. Expected outcome: increased knowledge, cooperation commitment and establishment of consultative bodies

• The global level can use aggregated values (like TWAP)• The regional level needs more detailed information (maps)

Global scope- use of indicators -

• Indicators:Smart combinations of variables in order to describe the complex aquifer system in 20 easy to understand and intuitive indicators

• To enable comparison of TBAs:

Indicators will be aggregated per TBA and per national segment (1 value per TBA/national segment)

20 indicators Core indicators (TWAP)

1. Mean annual groundwater recharge depth

2. Annual amount of renewable groundwater resources per capita

3. Natural background groundwater quality

4. Human dependency on groundwater

5. Groundwater depletion

6. Groundwater pollution

7. Population density

8. Groundwater development stress

9. Transboundary legal framework

10. Transboundary institutional framework

Additional indicators (this project)

11. Aquifer buffering capacity

12. Aquifer vulnerability to climate change

13. Aquifer vulnerability to pollution

14. Human dependency on groundwater for domestic water supply

15. Human dependency on groundwater for agricultural water supply

16. Human dependency on groundwater for industrial water supply

17. Ecosystem dependency on groundwater

18. Prevalence of springs

19. Control of groundwater abstraction

20. Groundwater quality protection

Renewable Groundwater Per Capita

Long term mean recharge volume, incl. man-made components, divided by inhabitants on aquifer.

1. Low: < 1000 m3/yr/capita

2. Medium: 1000 – 5000 m3/yr/capita

3. High: > 5000 m3/yr/capita

Total annual groundwater abstraction divided by long-term mean annual recharge.

1. Very low: < 2%

2. Low: 2-20%

3. Medium: 20-50%

4. High: 50-100%

5. Very high: > 100%

Groundwater Development Stress = Abstraction/Recharge

Type of data needed

• Hydrogeological: parameters and variables– System boundaries, transmissivity, groundwater levels, rainfall,

recharge, etc• Environmental conditions

– Pollution (natural and anthropogenic), groundwater dependent ecosystems, aquifer vulnerability

• Socio-economic– Population density, dependency on groundwater (domestic,

agriculture, industry)• Legal / Institutional

– Water laws, regulations and agreements, characterisation of water management institutions (both: use and protection)

Data collection

• Sources:– Country data at aquifer level: Mainly existing data– Some global data-sets from TWAP (e.g. population)– Maybe some in-situ data collection (if feasible)

• Tools:– Questionnaires– Protocols

• Who: – National Experts (National Technical TBA Groups) – Coordination by Regional Coordination Focal Point – Support from IGRAC

Groundwater Information Management System

Purpose of Groundwater Information Management System:• Supports the assessment process and

serves as TBA management tool through: collection, storage, visualisation, analysis and sharing information

• TWAP Project context:– Facilitates comparison of TBAs– Enables replication of the assessment
