Renewable Water Recources - Significant improvements in streamflow data coverage due to the integration the SoE water quantity data and JRC LISFLOOD data Only Turkey and Iceland are missing for the years on monthly resolution

Water use data algorithm has been significantly changed and updated Tourism data has also been included Water use

Assessment capacity of the EEA WA database -Regionalized WEI results of both formulas -Water abstraction by source and water use by sector

Seasonal water abstraction by economic sector ( )

Regional and seasonal variations in Water Exploitation Index More than 70 million inhabitants living under water stress conditions during summer

Some issues to be solved in the near future CONCEPTUAL ISSUES: -Open-ended conceptual questions, i.e. WEI tresholds -Uncertainities due to the insufficient data (change in water storage) -Opening and closing stock related issues in the water accounting -Lag effect, spatial and temporal aggregation etc. -Integration of Water Accounts with other environmental accounting components PROCESS RELATED ISSUES -Intensive data requirements (data provision, integration and assimilation) -High IT requirements for the computation
