2 Policy lines and EEA Water Accounts Components - Water scarcity conditions and quantitative use of water in Europe - Assessing resource efficieny and sustainability of water use across Europe - Providing further information on Natural Capital Accounting of Water (a) Physical supply and use tables 1. Flow accounts (b) Emission accounts (c) Hybrid and economic accounts (a) Produced assets 2. Asset accounts (b) Water resources (c) Quality accounts 3. Valuation of non-market flows

3 European Water Assets Accounts and Water Exploitation Index Temporal and spatial assessment of renewable water resources and sectoral water use update CSI 0018

4 Scope of the current EEA Water Accounts (based on the UN SEEA-W Temporal and spatial assessment of renewable water resources and sectoral water use update CSI 0018 Assessment reports

5 Calculation of Renewable Water Recources WEI+ = (Abstractions Returns) Renewable Water Resources RWR 1 = ExIn + P ETa ΔS nat F1 RWR 2 = Outflow + Abstractions Returns ΔS art F2 WSB Southern Apennines coastal (2007)

6 Renewable Water Recources WEI+ = (Abstractions Returns) Renewable Water Resources RWR 1 = ExIn + P ETa ΔS nat F1 RWR 2 = Outflow + Abstractions Returns ΔS art F2 F1 F2 RENEWABLE WATER RESOURCES - SUMMER

7 European overview on Water abstraction and use by source and sector Water abstraction by source (Annual and Seasonal)

8 European overview on Water abstraction and use by source and sector Water Use by sectors (Annual)

9 European overview on Water abstraction and use by source and sector Water Use by sectors (Seasonal) WINTER SUMMER

10 European overview on Water abstraction and use by source and sector Dominant sector of water abstraction WINTER SUMMER

11 Country Scale Water Exploitation Index Which formula is more capable in capturing temporal and spatial variations!?... F1 F2

12 Regional and seasonal differentiations in WEI across Europe (River Basin District vs Sub basin) WINTER SUMMER F1

13 Regional and seasonal differentiations in WEI across Europe (River Basin District vs Sub basin) WINTER SUMMER F1

14 Regional and seasonal differentiations in WEI across Europe (River Basin District vs Sub basin) WINTER SUMMER F2

15 Regional and seasonal differentiations in WEI across Europe (River Basin District vs Sub basin) WINTER SUMMER F2

16 Regional and seasonal differentiations in WEI across Europe (comparion of both formulas) F1 Winter Spring Summer Fall F2

17 Main outcomes - Both formula indicate that rivers and groundwater bodies are under pressures especially in summer. - Reservoirs are playing very curcial role in supporting seasonal water demands in summer by almost tripling their water supply to the economy - Resource efficieny measures are needed to be implemented particularly in water supply and agricultural sectors - Formula 2 results better reflect the economic pressures on freshwater resources
