4 PRESSURE & IMPACT SURFACE WATER BODIES (SWB) Define a strategy for new WFD cycle exemples of key policy elements I - Purpose to fine tune programme of measures Increased knowledge to identify measures to reduce pressures on Water Bodies II - How to define robust methods for pressure/impact analysis Strategy for data collection to increase efficiency/ transparency III- How to improve degree of confidence of results (data quality) Invest in monitoring, capacity building, perform additional surveys IV - How to show progress/benefits, explain efforts still required to remove pressure The price to pay/ transparency/ show improvements (long term trends) V - How to introduce new concerns: climate change, drought, floods Impacts on hydrology, hydromporphology, water uses

5 I - FINE TUNE PROGRAMME OF MEASURES

6 I- FINE TUNE PROGRAMME OF MEASURES Type of pressure Surveys Significant or not Specific parameters impacted Monitoring One out all out One parameter bad : bad status! (even when all other parameters good) Need to assess how to reduce efficiently pressure (priorities ) Better knowledge of the origin/impact of pressure Relevent sets of measures / priority areas/ OSMOSE national tool for programme of measures «Smart analysis» focused on specific parameters relevent for improved status Specific set of measures

7 I- Need to assess how to further reduce pressure (priorities) Agglomerations : - Sewage systems, Waster Water Treatment Plants constructed Quality of management, Permits issues and their enforcement (IPPC)? Other point pressures Diffuse pollution: agriculture, other sources (urban surfaces ) Hydromorphology Degree of reduction of Nutriments (N,P, C) discharged in river? Is WB status improvement observed? Which option for further reduction What indications from surveys and screening of dangerous substances discharged can be used to tailor sets of measures? How to improve implementation/ monitoring of good practices and their impact? Compliance with / acceptence of hydromorphological measures :fish passes, water management practices, operation on river beds sociology

8 I- Better knowledge of the origin/impact of pressure Well-defined point sources or not? Diffuse pollution origin Data from permits issued, new activities, activities phased out.. Multiple sources Scientific studies, land cover, statistics from various sources.. Vulnerability of water bodies/river Basin territory Assessment of respective impact of pressures sources in the future.. 1) Improve database completeness and accuracy : GIS RESOLUTION, COORDINATES, DISCHARGES/ABSTRACTIONS, MONITORING PARAMETERS Planning process 2) Visualise, inform, get data through the WATER INFORMATION SYSTEM 3) Practical means to incoporate knowledge of stakeholders and operators (enrichment of database, economic analysis & measures selection) STAKEHOLDER INVOLVEMENT PLAN. SOCIOLOGICAL STUDIES 4) Robust analysis for assessment of impact of pressure in the future : simple tools & expert judgement (studies on CLIMATE CHANGE)

9 I- Relevent sets of measures & priorities A - Governance common strategy for partners in programmes of measures implementation Improve the hydrological network / climate change Data quality management B - Geographical priorities Fiches : summary of measures by sub-basins/ administrative areas C: National tool to inform, report and plan measures : OSMOSE Register all measures planed to achieve the good status of water bodies - Restoration of river beds - Reduction of pollution loads, etc. VISUALISATION OF ACTIONS BY TERRITORIES ( )

10 II - ROBUST METHODS FOR PRESSURE / IMPACT ANALYSIS

11 II - ROBUST METHOD OF PRESSURE/IMPACT ANALYSIS IMPRESS Guidance document The pressures and impacts analyses should be focused in such a way that the effort involved in assessing whether any body, or group of bodies, is at risk of failing to achieve its environmental objectives is proportionate to the difficulties involved in making that judgement.

12 II - LANDCOVER - URBAN/FOREST AREA/POPULATION DENSITY Global index of pressure Unit : surface water body catchment Indication of the level of pressure Where data are insufficient Possibility to define multi-criteria index Multi-criteria index useful for assessing the ecological status «extrapolation» model tested by IRSTEA in France to estimate probable ecological status of Surface Water Bodies

13 II - SWB status & objectives from upstream to downstream SWB status : chemical, biol., Hydromorphy, ecological (2007) Date for achievement of Good status Chim 2015 Biology Zorn sub River Basin Rhine River Basin District

14 II - Not good status : analyse quality elements Chemical St. Degree of confidence Biological St. General parameters Substances Surveillance of water body at risk shows the situation for relevent parameters Economic analysis : possibility to justify less stringent objectives - in this case very low flow at discharge point & already high degree of pollution treatment

15 II- Select indicators for assessing trends WISE, European Environment Agency indicators - Trend over 40 years for a parameter NH4 +, Mosel river (monitoring station : Sierck) Index selected to observe trend over 10 years (exemple biological index IBGN) Index selected to observe what prevent to reach good status (phosphorus) What is requested for WFD reporting NH 4 Show progress due to measures implemented Situation is improving but the rule «one out, all out», do not show progress, when only a global indicator is used

16 II- Sewage networks & wastewater treatment plants

17 II- Impact of measures : selected index IBGN 1993 to 2007 Zorn River Basin, West of Strasbourg Evolution of a water quality biological index IBGN Quality classes of the French evaluation system SEQ-Eau

18 II- Visualise progress / parameters with appropriate indexes Index IBGN use from 2000 to 2010 Slow progress Evolution of phosphorus index Phosphorus Factor identified -phosphorus Slow progress

19 III - DEGREE OF CONFIDENCE OF RESULTS (DATA QUALITY)

20 III - MORE PRECISE WATER BODY STATUS ASSESSMENT Status of Water Bodies in 2009 Status of Water Bodies in 2012 Water body status assessed with monitoring information Overall picture of the situation changed : water body were considered not at bad status in 2009 are shown in 2012 at bad status. Reason :measurement were performed and replace expert judgement (which was too optimist). Consequence : difficult to evaluate progress from 2009 to 2012, but Better knowledge of the quality elements through monitoring of small streams

21 III - Investigate, explain adjust measures Ecological status in 2012 Macro-pollutants index 2009 Distribution of cost of measures by «sectors» Results might seems disapointing compared to investments Investigate then Explain reasons Adjust measures

22 IV - SHOW PROGRESS/ BENEFITS, EXPLAIN EFFORTS STILL REQUIRED

23 IV IV- - SHOW IMPROVEMENTS, EXPLAIN OBSERVED STATUS RHINEMEUSE BASIN Water Quality evolution with same index from 1971 to 2010 RHINEMEUSE BASIN Ecological status 2012 Explain the consequences of the change of indicators Nitrate concentration 1973 to 2005 Rver : Rupt de Mad Use specific indicators that show - improvements of the status - the pressure to be reduced

24 IV - INFORMATION SYSTEM DISPLAYING PRESSURE & STATUS, etc. France - Water information System (WIS) Rhin-Meuse WIS III - Datasets Shape files, pdf documents downloadable Queries for pressure/impact analysis Webmapping : interactive maps

25 IVII IV-- 1 Rhine-Meuse Information System : pressures, quality elements Vpressures List of identified By water body : parameters / status evaluation Industry Agglomerations Land Cover Dangerous substances

26 IV - INDEX TO SHOW THE PRICE PAID Index of water price from 1994 to 2009 in France ( INSEE) Increase of price led to better water quality and related socio-economical benefits! Different picture when looking at water bodies status! Still a price to pay to achieve good status but Decrease of water price envisaged : main investements performed in France)

27 V- CLIMATE CHANGE, DROUGHT, FLOODING IN PLANNING PROCESS

28 V- CLIMATE CHANGE, DROUGHT, FLOODING IN PLANNING PROCESS A - Review of available information in the web Produce a synthetic document for stakeholders & planners National methodology : introduction climate change, drought, flooding thema in planning documents B identify vulnerabilities, measures for adaptation Specific studies by sector / matrix of analysis Case studies in the vulnerable areas: change in impact of pressure Mobilise resources to adjust, rehabilitate hydrological monitoring for long term studies on climate change C Intersectorial approach international perspective Contribution to debate/ strategy for energetic transition Contribution to scientifi studies modelling, etc

29 Conclusions 1 - Purpose of this presentation was to give a feedback from experience 2 - Point out necessity of robust analysis instead of lunching detailed complex process 3 Degree of confidence of data should be a main concern 3 - Prepare information, maps, papers to explain and have stakeholders and public understand what is done/ what is to do, what are the good news 4 - Climate change, drought, flooding, new thema : widen the perspective, not only Water.international perspective, give the floor to scientics
