Costs, benefits and climate proofing of natural water retention
measures (NWRM)Valentina Villoria – Ömer Ceylan
Coordination Workshop Preparation for the WS&D Policy Review and the
Blueprint for Europe's Waters
29 June 2011
Methodological and quantitative basis for identifying the financial needs and policy implications at the EU level for NWRM
Costs and benefits, and resilience to climate change of NWRM and EU policy and funding instruments to promote no-regret measures
Best instruments to create synergies between the EU policy framework and no-regret measures at a river basin level
Objectives
1. Structure the information gathered in the call for evidence and complementary sources
2. Provide a quantitative estimate of the potential for NWRM at EU level, and aggregated figures for costs and benefits
3. Analyse the potential implementation barriers or critical success factors for no-regret measures in EU policies, leading to practical recommendations
Tasks - overview
1. Structure the information gathered in the call for evidence and complementary sources Typology of measures and river basins Available literature and case studies (e.g., LIFE+,
INTERREG, FP6/7 projects) Metadata Catalogue Gaps in the information Metadata Catalogue design (in MS Access and to be
compatible with WISE and EU Adaptation Clearinghouse)

2. Provide a quantitative estimate of the potential for NWRM at EU level, and aggregated figures for costs and benefits
Choose a geographically and typologically representative sample of measures
Provide the JRC the main parameters for an EU-wide modelling of NWRM
Provide the JRC with Policy Scenarios (e.g., implementation of one or various measures)
Modelling by JRC (at least three CC vulnerability scenarios)
Task 2
2. Provide a quantitative estimate of the potential for NWRM at EU level, and aggregated figures for costs and benefits
Effectiveness of measures at EU level (flood risk prevention, etc.)
Aggregated costs and benefits
Costs and benefits of no-regret measures (emphasis on co-benefits)
Task 2
3. Analyse the implementation barriers or critical success factors for no-regret measures in EU policies
Relevant EU policies and EU funding instruments
Result: Policy recommendations
