  • Renewable groundwater resources per capita: Long-term mean ground-water recharge (VOLUME), including man-made components, divided by the number of inhabitants of the area occupied by the aquifer This gives an indication of the sustainability of the system and the carrying capacity of the groundwater system in relation to the population.
  • Groundwater development stress: Total annual groundwater abstraction divided by long-term mean annual groundwater rechargeNote: It’s not by definition “good enough” to stay below 100% It depends on the system what is a critical value. In some systems 20% might already cause problems.

    1. 1. Aquifer Characterisation, Indicators and Information Management Dr Neno Kukuric, IGRAC
    2. 2. Groundwater from Global Perspective      IGRAC - International Groundwater Resource Assessment Centre (since 2003) is UNESCO and WMO groundwater centre IGRAC facilitates and promotes global sharing of information and knowledge required for sustainable groundwater resources development and management Focused on information and knowledge management, transboundary aquifer assessment and groundwater monitoring Receives financial support from the Government of The Netherlands In-house partner of UNESCO-IHE in Delft, The Netherlands
    3. 3. IGRAC Portal www.un-igrac.org
    4. 4. Trans-Boundary Aquifer (TBA) Assessment     The fact: many aquifers cross the political borders Potential cross-boundary problems: changes in flow, levels, volumes (quantity) and dissolved substances (quality) Actions: adequate monitoring and assessment; joint management Benefits: eliminating potential sources of conflict and improving the overall benefit from groundwater.
    5. 5. Transboundary Aquifer Assessment  ISARM – Internationally Shared Aquifer Resources Management  UNECE Assessments in Europe and Asia    Participation in GEF (Global Environment Facility) projects Development of a TBA Methodology and a TBA Course, contribution to UNILC, WWAP, … Transboundary Aquifers of the World Map
    6. 6. ISARM Portal www.isarm.org
    7. 7. Transboundary Aquifer Assessment
    8. 8. TBA Aquifer Assessment  Hydrogeological Aspect    Delineation and description Classification, diagnostic analysis and zoning Data harmonisation and information management  Environmental issues  Socio-economic framework   Institutional settings International legal framework
    9. 9. TBA Aquifer Assessment Multi Country Consultative Body Data collection (mainly existing) Data harmonisation TBA assessment Proposal for harmonised monitoring Sustainable management of TBA
    10. 10. 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)
    11. 11. 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
    12. 12. Data Harmonisation
    13. 13. Transboundary Aquifer Indicators • Indicators: Smart combinations of variables in order to describe the complex aquifer system in easy to understand and intuitive way • To enable comparison of TBAs: Indicators will be aggregated per TBA and per national segment (1 value per TBA/national segment)
    14. 14. Transboundary Aquifer Indicators Pretashkent Trifinio Stampriet Data collection Data Aggregation Indicator based Assessment Comparison of TBAs (TWAP)
    15. 15. Transboundary Aquifer Indicators Core indicators (TWAP) Additional indicators 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 1. 2. 3. 4. Aquifer buffering capacity Aquifer vulnerability to climate change Aquifer vulnerability to pollution Human dependency on groundwater for domestic water supply 5. Human dependency on groundwater for agricultural water supply 6. Human dependency on groundwater for industrial water supply 7. Ecosystem dependency on groundwater 8. Prevalence of springs 9. Control of groundwater abstraction 10. Groundwater quality protection
    16. 16. Renewable Groundwater Per Capita 1. Low: < 1000 m3/yr/capita 2. Medium: 1000 – 5000 m3/yr/capita 3. High: > 5000 m3/yr/capita Long term mean recharge volume, incl. man-made components, divided by inhabitants on aquifer.
    17. 17. Groundwater Development Stress = Abstraction/Recharge 1. Very low: < 2% 2. Low: 2-20% 3. Medium: 20-50% 4. High: 50-100% 5. Very high: > 100% Total annual groundwater abstraction divided by long-term mean annual recharge.
    18. 18. Groundwater Information Management System Purpose of Groundwater Information Management System: • Supports the assessment process and serves as a TBA management tool through: collection, storage, visualisation, analysis and sharing information • Contemporary ITC allows easy access and easy maintenance of web-based systems – Structural data & information storage (and on-line visualisation and processing) – project outcomes are preserved, easily available and reusable
    19. 19. GGIS - Global Groundwater Information System     Global Overview (ca 70 world maps showing aggregated groundwater related attributes per country) Meta Information Module (people, organisations, documents) Global Groundwater Monitoring Network (facilitate monitoring the state of global groundwater resources) Collaborative Environment (forum facility, on-line project archive )
    20. 20. GGIS: Country-based and TBA-based Approach Country-based information Transboundary Aquifer –based information
    21. 21. Transboundary Aquifer Assessment – detailed Aggregated values (Spatially) distributed values (point data, vectors, polygons, imagines, ..)
    22. 22. Global Groundwater Information System Accessibility Interactivity User Friendliness Ownership Agreements Authorisation
    23. 23. Monitoring of Groundwater Change  GGMN, Global Groundwater Monitoring Network is a participative, webbased network of networks, containing measurements and aggregated estimations GGMN
    24. 24. Monitoring of Groundwater Change
    25. 25. Final remarks Climate change and human impact on groundwater resources does not stop at the country borders
