Chagiou, E. Chiotis, M. Ghini, G. Gioni, E. Interwies, A. Morfis, M. Stefouli Presenter: E. Interwies, Ecologic Session 4.1: WFD Economic elements

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project2 Structure of the presentation: Aims of the project Short overall description of the situation on Corfu Selection of main findings of the project The way forward for the Economic Analysis in Greece

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project3 Aims of the project I: Check selected elements of the WATECO- guidance draft, mainly: linking hydogeological to economic information description of main water uses assessment of water demand pricing of water (public supply)

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project4 Aims of the project II: Provide input for finalizing the WATECO- guidance (done) Provide input for implementing the Economic Analysis in Greece by identifying main gaps (based on initial scoping)

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project6 Description of situation in Corfu Corfu Island dealt with as a river basin, but without a river! Water for all uses: groundwater origin High seasonality of water demand (tourism), water supply constant in time Groundwater deterioration due to: - natural reasons (presence of gypsum and natural sea water intrusion) - human activity (groundwater overexploitation)

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project12 Results: Importance of water uses Main use: household and tourism Significant additional use: agriculture Not significant: “industry” (rather: manufacturing) Overall: water related activities are strongly affected by geomorphological characteristics of Corfu

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project13 Results: spatial economics Detailed view of Ropa valley Primary use of water for tourism: Only the golf terrain is irrigated

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project14 Results: Projecting trends for 2015 Crucial element of the 3-step-approach: Large gap between the requirements of the guidance document and reality only estimates available for future water demand on 2038, based solely on demographic changes/estimates of per head consumption large amounts of new data needed out of existing information, no estimation on the baseline scenario can be given

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project15 Results: Assessing cost recovery A number of sub-steps (information) is needed for this estimate, focus here on: water pricing of municipal water supply, pricing in agriculture costs of water supply --> issues of charges, fees, taxes, relevant public subsidies/grants, cross-subsidisation, environmental costs: not considered

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project16 Results: Water pricing issues No aggregated information available, primary data: Public water supply of the 12 municipalities: different tariff systems In some cases: special tariffs for entrepreneurial uses In 2 cases: special tariffs for agricultural use; 2 local irrigation organisations have tariffs covering operation costs In order to compare prices, different consumption values were assumed: wide variation of prices for public supply, most with a gradual price increase for higher consumption, some cases show a decrease

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project17 Results: cost of water supply very limited information on agriculture public water supply: centralised data does not exist, local water suppliers asked for information no estimation on cost recovery can be given: - no estimates on environmental/resource costs - information on financial costs of water supply was fragmentary

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project18 Evaluation A non-virtual exercise to be used as a framework for the economic analysis in Greece, but: time and financing constraints, therefore not complete “testing” Linking economic to hydrogeological information (Annex II WFD) is important WATECO-guidance useful, but requires a lot of economic understanding A good starting point for understanding the need of improvement of the water management structures in Greece

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project19 Evaluation Large efforts needed in Greece for delivering the Economic Analysis in time, due to limited: data availability and quality; centralised availability of data; awareness of the WFD and water-economic capacities in water administration methodological knowledge

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project20 Support by: Recently commissioned program for the development of water resources management systems (divided regionally according to the water districts), aimed at the development of Water Resources Management Plans (duration: 36 months) --> some support for the economic analysis can be expected from these studies

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project21 The axes for improvement Accelerate the establishment and staffing of the regional “competent authorities” as well as the central water institution (reduce overlaps between ministries)--> will happen soon Provide adequate resources and capacities for conducting the economic analysis (2004: at the central level) Establish a clear “plan of action” including strict deadlines (“critical path”)

ecologic.de , Hellenic Water Week: Testing the WATECO-Guidance: Corfu Pilot Project22 The axes for improvement Improve data availability and quality (primary data) Urgent need for raising awareness and inform local water administrations about the WFD requirements --> strong political support will be needed!
