The Impact

This thesis aims to analyse and comment on the impact of large agri-environmental policy directives in the welfare of European citizens. THe focus of this thesis is on the Water Framework Directive which had as its orearching target to achieve Good Ecological Status for all European water bodies. The directive set out an integrated river basin management framework which in turn was at the juristiction of regional bodies to implement. The purpose of the theisis is to offer a balanced approach from both the social and the economic side of assessing such large pieces of legislation, without turning a blind eye to its shortcomings, while aknowledging its importance to the European Union goals. The approach of the thesis is anthropocentric, which is not always the case in neoclassical economic theory, which has influenced the design of the Water Framework Directive. The thesis prides itself in its analysis of the impacts of the directive during its design state and its implementation state as well. Finally, the thesis comments on its findings from the viewpoints of physical, social and economic sciences.In particular, the thesis attempts to answer the following questions:1. What are the real implications of large pieces of policy work such as the Water Framework Directive on human welfare?2. Which is, if any, the impact and value of scientific models in the design of case-specific agri-environmental policies for river basins?3. Are such directives cost-effective in their implementation in the regional level?4. Who benefits more from these directives, poorer or richer househlods?5. If individual perceptions on risk are taken into consideration, how well do these reflect the true threats to the water environment, and how that affects public consultation in the preparatory phase of such directives?6. How do European-set ecologcal and environmental indexes for the waters help European citizens realise the true threats to the water bodies in their region?

The European Parliament and The Council of the European Union have established the Water Framework Directive (2000/60/EC) for all European Union member states to achieve, at least, “good” ecological status of all water bodies larger than 50 hectares in Europe. The MultiSpectral Instrument onboard European Space Agency satellite Sentinel-2 has suitable 10, 20, 60 m spatial resolution to monitor most of the Estonian lakes as required by the Water Framework Directive. The study aims to analyze the suitability of Sentinel-2 MultiSpectral Instrument data to monitor water quality in inland waters. This consists of testing various atmospheric correction processors to remove the influence of atmosphere and comparing and developing chlorophyll a algorithms to estimate the ecological status of water in Estonian lakes. This study shows that the Sentinel-2 MultiSpectral Instrument is suitable for estimating chlorophyll a in water bodies and tracking the spatial and temporal dynamics in the lakes. However, atmospheric corrections are sensitive to surrounding land and often fail in narrow and small lakes. Due to that, deriving satellite-based chlorophyll a is not possible in every case, but initial results show the Sentinel-2 MultiSpectral Instrument could still provide complementary information to in situ data to support Water Framework Directive monitoring requirements.

The Impact

Hydropower plants produce renewable and sustainable energy but affect the river’s physico-chemical characteristics and change the abundance and composition of the aquatic organisms. The impact of large HPPs on the ecological conditions of surface water bodies have been extensively studied, but less attention has been paid to environmental impact studies of small hydropower plants (SHPs). The impact of hydropeaking on both the river flow regime and ecosystems has been well-studied for peaking mode plants, mainly medium to large-sized ones. However, for small hydroelectric power plants, and especially for those in lowland rivers, the available information on water quality, benthic macroinvertebrates communities and fish abundance, and biomass is not sufficient. Ten small hydropower plants were selected, and the ecological status of water bodies was assessed in different parts of Lithuania. The studies were performed at the riverbed upstream from the SHPs, where the hydrological regime has not changed, and downstream from the SHPs. It was found that the small hydropower plants do not affect the physico-chemical values of the water quality indicators. This study demonstrated that the total number of benthic macroinvertebrates taxa (TS) is influenced by the concentration of nitrogen and suspended solids, the water flow, the river area, and the current speed; the number of EPT (Ephemeroptera (mayflies), Plecoptera (stoneflies), and Trichoptera (caddisflies)) taxa is influenced by the concentration of nitrogen and suspended solids. The studied indicators do not have a significant impact on biomass. The SHPs affect the fish abundance and biomass. The Lithuanian fish index (LFI) is influenced by the average depth and area of the river. Some SHPs operating in lowland areas may yield somewhat significant hydrograph ramping but more detailed investigation is needed to support the significance of this impact on the biological indices.

The Impact

In the European Region agriculture is the second largest water user after power industry cooling water use. As part of the implementation of Water Framework Directive EU Member States prepared their river basin management plans by the end of 2009 or first half of 2010, In these plans impacts of agriculture on water bodies have received attention. The detailed information elaborated in the plans by countries and river basin districts were uploaded into the WFD section of the WISE system. This database provides opportunity for multi-criteria analysis for different water types. The paper discusses the effects of agriculture on hydromorphological pressures and impacts affecting surface water bodies. It was pointed out that among the pressures affecting European surface water bodies the hydromorphological and diffuse pressures represent the highest ratios (Figure 1). Within the hydromorphological pressures affecting classified surface water bodies the ratio of pressures related to agricultural activities is low,it does not exceed 1% at European level. In case of Hungary the agriculture related river management pressures effect about 80% of the surface water bodies, which is much higher than the corresponding European average. The agricultural water abstractions affect about 10% of the Hungarian surface water bodies (Figures 2 and 3). The river and lake water bodies are impacted in significant ratio by nutrient enrichments and organic material enrichments, while in case of river water bodies the impact of organic material enrichments is also significant (Figures 4 and 5).

AbstractThe Water Framework Directive (2000/60/EC) establishes a framework for integrated water management and functions as a major legal frame for the protection of water bodies in Europe. In the Flemish Region the Directive has been implemented by the Decree of 18 July 2003 on Integral Water Policy. As climate change affects the quality and quantity status of water bodies, the question arises whether the Water Framework Directive (WFD) and the Flemish implementation legislation are well-suited to handle climate change impacts. Although climate change concerns are not explicitly incorporated in the text of the WFD and the Flemish Decree, this author believes that the main components for an effective adaptation strategy are included in the above mentioned legislation. More in particular, this is achieved by the environmental objectives which have to be elaborated in environmental quality standards (EQS) on the one hand, and the integrated approach on the other hand. Water quality management on the basis of a high level of protection of the aquatic environment is indispensable for adapting to climate change, as ecosystem-based adaptation is most cost-effective. Therefore spatial planning should integrate water quality concerns, as spatial planning may be critical for spatial quality and more specific for the achievement of the environmental objectives. Consequently this contribution focuses on the impact of water quality standards on permit decision-making and spatial planning. In this context some legal instruments anchored in the Flemish legislation on integral water policy will be highlighted, especially the 'watertoets' (translated as the water checkup), which may be useful to facilitate adaptation to climate change.

Abstract. Hydromorphological deficits are of real concern regarding the goals of the European Water Framework Directive to reach a good ecological status. The effects of measures that change the morphological structure of a river is hard to predict. Existing methods to simulate this process in a traditional numerical model can not be applied to whole river systems. Using a rule-based modelling concept to find feasible measures and predict the impact of those measures is a very promising solution.

Use Of Resources

<p>The existence of strong potential synergies between the Water Framework Directive (WFD) and the Habitats Directive (HD) is widely acknowledged. Indeed, ensuring favourable conservation conditions for aquatic habitats and species of conservation concern is closely related to the achievement of a good ecological status in water bodies. However, since these two sets of European laws are generally applied without any coordination, an inefficient use of resources may adversely affect their goals. The main negative outcome is an increase in the cost of monitoring programs for collecting data in nature (<em>i.e.</em>, physical and chemical parameters, species and habitats, plant communities). The use of macrophytes as a bioindicator, as imposed by the WFD, may instead help to integrate data on aquatic EU habitats and enhance knowledge of such habitats outside the Natura 2000 network. The aim of present study was to evaluate the usefulness of data collected in WFD monitoring surveys as a means of inferring the occurrence and the distribution of lacustrine aquatic habitats in countries belonging to the European Union (EU). The main aim of the analysis was to identify the depth gradient distribution of diagnostic macrophyte <em>taxa</em> in two EU habitats (3140, <em>i.e.</em>, <em>Chara</em>-dominated benthic communities, and 3150, <em>i.e.</em>, natural eutrophic lakes) using data collected in lakes in Lombardy (northern Italy), some of which are included in the Natura 2000 network (10 out 16). While recognizing the limitations of the data collected within the two frameworks, the results confirmed the marked usefulness of WFD data as a means of enhancing the knowledge available on lacustrine aquatic habitats in the EU. WFD data can actively help to improve the basic information on aquatic habitats, thereby more effectively supporting regional strategies for biodiversity conservation as well as recovery programs.</p><p> </p>

After 25 years of EU water legislation the European Union has just thoroughly restructured its water policy. The European Parliament and the Council, following a tough conciliation procedure between the two legislators, have in summer 2000 agreed a proposal by the European Commission for a Water Framework Directive. This legislation will have the following main objectives:integrated river basin management across borders, with coordinated programmes of measuresprotection of all waters, surface waters and groundwater, in quality and quantity with a proper ecological dimensionemissions and discharges controlled by a “combined approach” of emission limit values and quality standards, plus the phasing out of particularly hazardous substancesintroducing water pricing policiesstrengthening public participation This new Water Framework Directive adopted in September 2000 will complement existing EU water legislation on nutrients reduction - the 1991 Directive on nitrates pollution from agricultural sources and the 1991 Directive on urban waste water treatment. These Directives will remain main pillars of EU water policy whilst at the same time being integrated into the river basin management in a coherent way.

Water Framework Directive (WFD) statutory authorities and stakeholders in Ireland are now challenged with the issue of how the proposed programmes of measures in the newly required River Basin Management Plans – designed to protect and restore good ecology by reverting as closely as possible back to natural conditions – are to be implemented in a way that concurrently complies with other existing and emerging intersecting European Union legislation, such as the Floods Directive (FD). The WFD is driven largely by ecological considerations, whereas the FD and other legislation are more geared towards protecting physical property and mitigating public safety risks. Thus many of the same waterbodies, especially heavily modified waterbodies, arguably have somewhat competing policy objectives put upon them. This paper explores the means by which Ireland might best achieve the highest degrees of cost effectiveness, economic efficiency and institutional durability in pursuing the common and overarching objective of the WFD and FD – to ensure Irish waterways are put to their highest valued uses.

The Impact

The growing race of urbanization and population growth lead to anthropogenic load on the water is increasing all the time. High population density and considerable industrial potential of the urbanized territory are becoming dominant sources of pollution of water bodies. This trend identifies progressive pollution of water bodies and the growing need for sanitary-ecological status of water control facilities. Natural chemical composition and properties of water in surface water bodies are formed depending on the hydrological, soil, climate and other features. Flowinduced suspensions in urban watercourses is one of the main ways of contamination distribution in urbanized areas. For monitoring and reducing the negative impacts on the water quality of watercourses requires estimation of anthropogenic pressures and studying its spatio-temporal variability. Analysis of anthropogenic stress on water objects allows you to set the relationship between the number of coming in the water body of pollutants and concentrations of chemicals in the water. The main aim is to determine the amounts of contaminants accumulated in the river riverbed during the period of the economic utilization of the watercourse and to assess the impact of urbanization on its ecological status. The article deals with the influence of anthropogenous load on river hydraulics and properties of channel sediments that determine the course of channel processes and overall ecological condition of water objects. The interrelation between water body condition, water quality and sediment pollution is presented. Method of estimation of anthropogenous load pollutants in river of urban area sis proposed. Comparative analysis of the load for the rivers of Russia with various water run-off is demonstrated.
