1. What did we learn from yesterday’s discussions? Water Resource Efficiency Workshop Thursday 16th and Friday 17th June, 2011 European Environment Agency, Copenhagen

2. Agreed (1) Terminology needs to be clarified (difference between technological and economic efficiency, difference between « private » and « social » efficiency e.g.) There is no relevance to estimate an « EU wide » target as water efficiency is « context relevant » (needs to account for the specificities of the « human- ecosystem ») Distance to target – not for « water resource efficiency » (unlike energy) but for the « status » of water (« water balance », GES, ecosystem resilience… )

3. Agreed (2) Data availability (and acceptance from MS….) is a driving factor for defining indicators that can be monitored in a « sustainable manner » There might be logicical steps for EU wide (EEA) assessments: – Step 1 – water scarcity index (seasonal, monthly?), WFD status assessment (basin, water body) – Step 2 – for hot spot, « demonstrate » with case studies the logics behind « water resource efficiency » (with water productivity and economic efficiency as relevant indicator in their « system’s context »)

4. More work to be done (1) The « purpose »/goal of investigating water resource efficiency needs to be clarified Linking water and other resources (e.g. water + energy + … jointly « captured » in indicators/assessments) The potential for water trading and adequate pricing as mechanisms for improving « water resource efficiency »

5. More work to be done (2) Scales – Country level indicators => trend analysis (as compared to country-based and sector-based (GDP-based) comparisons that might have limited relevance…) Need to test « global » approaches: 1) GDP - natural capital, 2) Matrix – GDP + water balance + emission + combined indicators Is there space for imports/exports, virtual water, footprint, blue- green-gray… – Local level assessment => work to be done on « the assessment hydro-logic » to account for society’s (and not private) optimum (economy, ecology, social…. Looking at different sectors at once)

6. We also discussed about… The EC Blue print Green growth Values, pricing/subsidies Tradable permits …
