Key WISE principlesKey WISE principles

Agreed and implemented in cooperation with DG Environment, JRC, Eurostat and EEA

Developing a distributed system by 2010 linking to the member states

Implementation plan until 2010 Bringing together SoE and compliance reporting Using Reportnet as tool for all this reporting Merging water related directives and the needed

data work (WFD, UWWT, Bathing, Nitrates, water statistics ...)

Provide data and information to the public

Outputs

Overall purpose: • provide representative periodic assessments of the status and

trends in the availability and use of freshwater resources• adequately monitoring the progress along with the European

policy objectives• improve water facts today to facilitate policy decisions and

issues

Three main questions to adequately capture the drivers, pressures

and state of freshwater resources are important:• What variables are useful?• What spatial and temporal scales are appropriate?• How to build on existing effort and where to expand?

What is needed ?

Why is it needed ?

• Adequately formulate indicators • Assess the state & trends of the WR and associated pressures• Monitor the progress with European policy objectives• Broader assessment of specific water-related issues in the

relevant conceptual ecosystem frameworks• Assess the impact of specific sectors, driving forces & responses

Water Scarcity and Drought Communication 18th JulyCommunication from the COM to the EU Parliament & the Council addressing the challenge of ws & drought in the EU {SEC(2007)993}{SEC(2007)996}

Need for more detailed and less aggregated data

The issue: reliable info is indispensable for decision-making, shared definitions are necessary, WISE provides the ideal platform to integrate and disseminate such informationWay forward: present an annual EU assessment, based on agreed indicators and data provided by MS and stakeholders to the COM or EEA on a yearly basis

Water quantity information

in WISE

How should it be reported ?

1. Data on Freshwater Resources Availability

Status and trends in the hydrometeorological parameters and the hydrological freshwater resources budget

Spatial aggregation: RBD level (scaled down to reflect spatial variability of WR and support adequate analysis)

Temporal aggregation: monthly basis (allow distinguishing seasonal patterns and assessing dry periods within a hydrological year, as well as investigating additional indices such as the “Dry season flow index, WRI)

Some additional data will be collected on surface water storage volume for the natural or man-made reservoirs in the RBD, and groundwater levels and storage for the main aquifer systems (comprehensive of the water resources’ availability trends over long-term and deeper assessment of water scarcity issues)

Streamflow data will be also compiled for selected gauging stations on a daily time step (provide a more complete national picture and assess additional hydrological trends, such as flood patterns, changes in the 7-day low flow etc.)

How should it be reported ?

2. Data on surface water & groundwater abstractions @ RBD level

• enhance the assessment, complimentarily with the OECD/Eurostat work, by including the aspects of seasonality, temporal and spatial variability

• Annual assessments at national level do not reflect regional trends and patterns…

thus a regionalization at RBD level is required, and a seasonal scale analysis is needed to accurately capture the evolution of water abstractions by source and sector

Water Resources Availability

Streamflow at selected gauging stations_Specifications:Daily data for the representative gauging stations (minimum of 10 years continuous measurements is desirable). Each representative GS and year should be described by a set of summary statistics (mean, maximum, mean annual minimum flow (MAM), etc.)

Representative GS: such as downstream stations at the main catchments and main tributaries. Stations may also be selected to describe natural flow such as stations unaffected by reservoirs or water abstractions. One GS/1000 km2 may be used as an indicative density

Test Data exchange for quantity during 2008

J F M A M J J A S O N D

Based on the reporting sheet EEA prepares reporting format (data dictionary and table) for a test data exchange via Reportnet

reporting of available info aggregated to RBD level – test scheme; no evaluation of performance

EEA analyse the reported information and prepares a background document on data availability and possibilities of streamlining reporting

Joint Eionet/SoE Group/Eurostat meeting (quantity experts) with experts, possibly together with COM on drought indicators

2009: Regular reporting of quantity data according to the agreed structure

Summary of suggested actions Improve water quantity data reporting

• Liase networksEIONET NRCs / WFDWater statistics

• Adress seasonal and spatial differentiation in water quantity reporting

• Joint expert workshop in mid 2008

Integrate water data from the Joint Questionnaire in WISE• Feasibility study in early 2008• Integration and harmonisation by 2009
