Dolan, Tom. "Water Framework Directive Article 7, The Drinking Water Directive and European Pesticide Regulation : impacts on diffuse pesticide pollution, potable water decision making and catchment management strategy." Thesis, Cranfield University, 2013. http://dspace.lib.cranfield.ac.uk/handle/1826/8401.
Full textAbstract:
The European Water Framework Directive (WFD) promotes increased awareness of catchment processes and challenges the established dependence on a ‘treatment-led approach’ for the supply of European Drinking Water Directive (DWD) compliant potable water. In particular, WFD Article 7 promotes a ‘prevention-led approach’ to DWD compliance, based on pollution prevention at source to reduce investment in new treatment. In this context the challenge of preventing diffuse pesticide pollution from agricultural sources is significant because metaldehyde (a molluscide) and to a lesser extent the herbicide clopyralid are, despite current treatment, causing DWD non compliance for drinking water in a number of English catchments. Analysis presented here identifies that a successful transition from a ‘treatment-led’ to a ‘prevention-led’ approach will require collective action from, and shared mutual understanding between, a number of stakeholder groups. However, each of these groups has a unique perspective on WFD Article 7 and other elements of the currently uncoordinated legal and voluntary framework for diffuse pesticide pollution prevention. A toolbox of intervention options and a set of criteria to evaluate current catchment management actions are proposed to help the WFD competent authority facilitate WFD Article 7 compliance. Water suppliers need to improve their understanding of the reasons for pesticide use. Through consultation with pesticide agronomists, important drivers of pesticide use, a hierarchy of adaptation options available if a particular pesticide is restricted and key messages for catchment managers and regulators were identified. Based on this foundation a classification system to inform and prioritise water sector decision making for investment in catchment management was developed. Additionally, analysis presented here demonstrates that the DWD standard for pesticides, which determines the level of catchment management required for WFD Article 7 compliance, is not itself consistent with European environmental policy principles, particularly the precautionary principle, and needs to be reviewed.

Full textAbstract:
The thesis studies one method, focus group discussions, for public participation in the starting of implementing the European Community Water Framework Directive at a catchment level. Focus group discussions can be used as a method for bringing relevant stakeholder-groups into the discussion and evaluation of different possible solutions to problems of managing local waters in order to lower nutrient emissions and stop eutrophication. Of special interest in the study is the participants’ development of collaboration and collaborative learning in the focus groups. Also of interest is their change in attitudes during the focus group process and their will to participate in similar settings. The thesis assesses the results of three questionnaires responded by focus group participants in a study carried out by the Swedish Water Management Research Programme, VASTRA. The participants represent stakeholders in Rönne å catchment in Skåne, and also the results from ten focus group discussions with the same participants.

Xerri, Francesca. "The capacity of organizations to deliver effective water management through the provisions of the Water Framework Directive : the case of Malta." Thesis, Cranfield University, 2016. http://dspace.lib.cranfield.ac.uk/handle/1826/11824.
Full textAbstract:
Effective implementation of the European Water Framework Directive (WFD) is dependent on Member States’ national water institutions and organizations, often designated as ‘competent authorities’. Although substantial research relating to the Directive itself has been carried out, less is known about the extent to which competent authorities have the organizational capacity to deliver it. The literature notes that conceptual understanding of capacity has been hampered by lack of definitional clarity making both its management and assessment challenging. In this contribution, several conceptualizations of organizational capacity found in the literature are used to construct a set of core qualitative organizational components that encourage analysts to consider the ways in which legal authority, information and knowledge, skills, resources and leadership shape a competent authority’s ability to deliver the WFD. Malta, the smallest European Member State, is the case study used to test the application of these components. Qualitative empirical data collected from policy documents, face-to-face semi-structured interviews and online news media articles, provided the evidence to thematically explore and evaluate the Maltese competent authorities’ organizational capacity across the implementation of three main WFD provisions that are in focus: Article 8, 9 and 14. As a result, the core components of organizational capacity are expanded and refined to produce an organizational capacity thematic map. The results show that competent authorities experience influences across the institutional frameworks they work in as well as external factors (primarily political). The results also support the idea of the organizational capacity components being highly interlinked and the presence (or lack thereof) of one component having knock-on effects on others within an organization. The combination of these two factors highly affect management options and outcomes in the implementation of the WFD. In the small state context of Malta these highlight the need to channel support in a coordinated manner from European counterparts to the Maltese water network. In turn, the water network can have positive knock-on effects on the organizational capacity of the Maltese competent authorities, which currently struggle to perform and seize available opportunities due to low possession of human resources and time availability. The approach and findings presented in this research provide a mechanism and evidence base that can facilitate bilateral discussions between Member States as well as with the European Commission, and help inform the WFD review process planned by end of 2019.

In particular with regard to the Euphrates-Tigris river basin." Thesis, Uppsala universitet, Institutionen för geovetenskaper, 2012. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-179998.
Full textAbstract:
Research focus: This paper asks to what extent the European Union (EU) can influence as an external actor Turkey’s integrated water management policy. In particular this paper focuses on the case example of the water conflict arising over the usage of the transboundary Euphrates-Tigris river basin and what extent the EU can bring to bear its influence on Turkey to bring a resolution to the management of this river basin. Method: This paper consists of a comparative literature review of recent journals, academic articles, official publications and website content as well as respected news website material. The research method used consisted of an analysis assessing the strengths, weaknesses, opportunities and threats facing the EU’s influence on Turkey’s water policy. Whilst this analysis tool is fairly straight forward to apply to assessing the EU’s influence on Turkey’s broad national water management policy, assessing how the EU can encourage Turkey to cooperate further on the International river basin of the Euphrates-Tigris is far more difficult, owing to the controversy and importance of the river to all three Countries sharing it; Turkey, Iraq and Syria. Findings: Through using a comparison of literature this paper has found that the main strength of the EU’s influence on Turkey’s integrated water management policy is through the very definite obligations Turkey must fulfil under the WFD as a candidate member for the EU. Secondly, this paper submits that the EU’s strong river management experience through large river cooperation projects, for example that of the Danube river basin, further enhances the ability of the EU’s credibility in its influence. The weakness the EU’s influence faces is the difficulty associated with Turkeys candidacy process to the EU which if hampered could quickly reduce the EU’s influence on Turkey. Opportunities for cooperation on the Euphrates–Tigris are also looked at positively in this paper especially in the light of a new Middle Eastern politics even though considerable uncertainty remains as to the full outcome. Lastly a threat that could face the EU’s influence is the results that a third way relationship between the EU and Turkey could have on limiting the EU’s influence with regard to integrated water policies. The main conclusion: This paper has concluded that the EU’s influence through the WFD is very strong on Turkey’s water policy, owing largely to Turkeys desire to obtain eventual full membership of the EU. Should the candidacy process fail, this could have a quick and damaging impact on the EU’s influence. This paper has also found that the EU has a strong potential influence in pushing Turkey towards further cooperation on the Euphrates-Tigris, however Turkey’s progress has to date been slow and remains a major challenge. This paper recommends that Turkey uses the Ministry for Foreign Affairs to open up dialogue with lower riparian river states towards cooperation, that the EU suggest setting up a ‘commission’ as a means of achieving improved transboundary river cooperation and the need for a research network or center to bring together efforts towards cooperation on the Euphrates-Tigris river basin.

Full textAbstract:
Following the implementation of the Water Framework Directive (WFD) integrated catchment management plans must be prepared for all river basins, in order to achieve 'good ecological status' (GES) in all EU waters. This concept is a broader measure of water quality than the chemical and biological measures, which were previously dominant in EU water policy. The Directive also calls for a consideration of the economic costs and benefits of improvements to ecological status in catchment management plans, along with the introduction of full social cost pricing for water use. In this thesis, the primary focus is on the use of the Choice Experiment (CE) method. The CE method is reviewed and then used to estimate the value of improvements in a number of components of ecological status on two Irish waterways (the Boyne and the Suir). Apart from CE method another stated preference approach to environmental valuation is also considered; the Contingent Valuation Method (CVM). This thesis determines what value the targeted population of the two catchments place on the nonmarket economic benefits of moves towards GES by employing both approaches and various model specifications, while the applicability of Benefit Transfer (BT) method is also assessed under different tests. In addition, the design of the questionnaire used in the survey stage of the research, offered the possibility of investigating issues related to the effect of cognitive ability and psychometric factors on choice. Respondents with discontinuous preferences are identified and analysis is conducted to investigate the implications of not accounting for these preferences. Finally, due to experiencing protesting behaviour by a proportion of the sampling population an attempt is made to investigate the parameters that contributed to this inclination.

Full textAbstract:
The issue of environmental risks from the pharmaceutical endocrine disrupter 17 alpha-ethinyl oestradiol (EE2), which is an active ingredient in the contraceptive pill, confronts government responsibilities for citizens' health with potential environmental risks from its presence in aquatic ecosystems. Further to a risk appraisal process conducted under the Water Framework Directive (WFD) between 2006 and 2012, the European Commission recommended the imposition of an environmental quality standard for EE2. In 2013, this recommendation was rejected by politicians. The outcome was both contested and commended. The UK Government was particularly vehement in its opposition and claimed that the risk assessment process for EE2 was not robust. The UK Government also insisted that it had swayed opinion of other EU Member States to convince them that action for EE2 was not proportionate given the extremely elevated costs of risk control options. At the present time, environmental policy for EE2 and other endocrine disrupters remains resolutely ineffective. Despite three distinct policy interventions recommending precautionary action for EE2 during the past twenty years, emissions of this potent, oestrogenic endocrine disrupter continue unabated. This thesis explains why European politicians rejected the European Commission’s risk governance recommendations for EE2 in 2013 under the Water Framework Directive. This comprises its principal empirical contribution. A novel analytical framework which draws on insights from the policy sciences, risk governance and wicked problems literature is developed. This framework is employed to determine whether the policy outcome for EE2, and the decision-making processes that preceded it, were legitimate. The research findings in this respect advance understanding of the implications of specific properties of wicked problems, of which it is argued, EE2 is an example, for the legitimacy of decision-making processes during the risk appraisal and political phases of policy development in Europe. This comprises the principle theoretical contribution of the thesis. Recommendations to promote more effective and legitimate policy development for wicked problems in similar multi-level governance contexts are also made.

Norberg, Matilda. "A paleolimnological perspective on liming – implications for defining reference conditions in Swedish lakes." Doctoral thesis, Umeå universitet, Ekologi, miljö och geovetenskap, 2009. http://urn.kb.se/resolve?urn=urn:nbn:se:umu:diva-20583.
Full textAbstract:
Using paleolimnological techniques, I have studied surface-water acidification and the effects of liming in Swedish lakes on a decadal to millennial time-scale. The overall objective was to contribute to the discussion on the fulfilment of goals within the Swedish liming program. One of the main goals of this program is to restore lakes to natural or nearly natural conditions, i.e. to a reference condition as termed in the EU Water Framework Directive. In this context, a key issue is to define reference conditions. This is a central theme of my thesis, as lake sediments offer a unique way to study past lake conditions. Past lake-water acidity of 12 reference lakes in the Swedish liming program (ISELAW) was determined using diatom analysis of sediment cores. Pollen, lead, and flyash from coal/oil combustion were used as indicators of impact from land use and atmospheric pollution. A general trend in these lakes is an initial decline in pH after lake formation due to natural soil processes, which was then followed by rather low pH values (pH 5.3-6.5). In six of the lakes pH increased as a result of expansion of agriculture (burning, forest grazing) 2000 to 1000 years ago. Local mining and long-range airborne pollution have also impacted the lakes since medieval time. These results show that the conditions of the study lakes were not natural prior to industrialization and recent (20th century) acidification. The ISELAW lakes were selected on the basis of representing typical limed lakes, and they have been limed and monitored since at least the 1980s. A comparison of chemical/biological monitoring data and the paleolimnological data gives somewhat diverging results. Most of the monitoring data suggest that the lakes were subjected to acidification during the 20th century, but the paleolimnological data can only identify clear evidence of acidification in five of the 12 lakes, hence, all lakes were probably not recently acidified. According to conclusions from monitoring the lakes have recovered following liming. The paleolimnological data give a more complex picture and three different responses have been identified: 1) a return to a diatom composition found in the lake one hundred to several thousand years ago; 2) very small shifts in the diatom composition; or 3) a diatom composition previously not found in the lake. The latter response raised the question whether liming can cause an unnatural diatom community. A comparison of diatoms in surface sediment samples of 31 limed lakes with pre-industrial reference samples from 291 lakes showed that liming does not create an unnatural diatom composition. These results illustrate that the goals for liming were not reached in all of the limed lakes, and that paleolimnology can play an important role for assessments of acidification and liming. The comparative study also highlights the importance of designing monitoring programs that can produce reliable and long data series. Given the results of the paleolimnological investigations, it is obvious that we cannot assume that the 19th century represented a natural or near natural state, and thus is a realistic reference conditions. Natural long-term lake development and previous land-use impacts need to be considered in defining reference conditions. Neither can we disregard the fact that humans always will impact nature. Although paleolimnological studies are time consuming, I believe that they could be simplified to the extent that paleolimnology could become a routine method for environmental management.

Full textAbstract:
La qualité des services écosystémiques qu'offrent les lacs est liée à la structure et au fonctionnement de leur écosystème. Protéger leur masse d'eau est devenu un objectif global qui requiert une meilleure compréhension de leur fonctionnement, un suivi et une évaluation de leur qualité. Expliquer les hétérogénéités spatio-temporelles des variables physico-chimiques et du phytoplancton est un problème récurrent rencontré en écologie et en hydrobiologie. Comprendre la dynamique de ces hétérogénéités est aussi un prérequis essentiel pour évaluer, protéger et restaurer objectivement les écosystèmes lacustres. En ce qui concerne la surveillance, les hétérogénéités spatio-temporelles introduisent des incertitudes sur la représentativité des mesures par rapport à l'entièreté de la masse d'eau qui est donc discutable et doit être vérifiée. En Europe, la directive cadre sur l'eau (DCE) initiée en 2000 définit un cadre pour la gestion et la protection des eaux. La classification des masses d'eau en fonction de leur état écologique est un point important dans l'implémentation de cette directive. Pour les lacs et les retenues, l'évaluation de cet état écologique est basée sur des paramètres biologiques, physico-chimiques et hydromorphologiques. Les indicateurs liés au phytoplancton et aux paramètres physico-chimiques sont calculés à partir de quatre prélèvements réalisés pendant la période d'activité biologique pour une année sur un plan de gestion de six ans. Dans ce contexte, la modélisation tridimensionnelle (3D) et la prise en compte des forçages qui conduisent aux hétérogénéités spatio-temporelles est une condition préalable nécessaire tant en limnologie appliquée que théorique. Cette thèse aborde la complexité du fonctionnement des lacs et la capacité des modèles 3D à reproduire leur fonctionnement. L'apport de la modélisation 3D est présenté i) pour la compréhension du fonctionnement de lacs de différentes tailles, ii) couplée aux observations satellitaires, pour l'étude de l'influence des forçages par le vent et de l'hydrodynamique sur l'abondance et la distribution spatiale de phytoplancton, iii) dans le cadre de la DCE, pour l'évaluation des incertitudes d'une évaluation de l'état écologique d'un plan d'eau. Pour cela, deux modèles 3D ont été créés et analysés, un pour le lac de Créteil (42~ha) et un autre pour le Léman (580~km$^2$). Celui du lac de Créteil a été validé à partir de données à hautes fréquences acquises en trois points du lac. Il reproduit correctement son hydrodynamique complexe, sa structure thermique, l'alternance entre les périodes de stratification et les épisodes de mélange, ainsi que les ondes internes. Le modèle du Léman a été validé en utilisant des données mensuelles et bimensuelles en deux stations de prélèvement du lac. Il reproduit aussi correctement son hydrodynamique et la variabilité saisonnière de paramètres physico-chimiques et biologiques. Les résultats des simulations mettent en avant les mécanismes physiques et hydrodynamiques responsables de l'apparition de sites où la biomasse de phytoplancton observée est plus élevée. Dans le cadre de la DCE, ces résultats montrent aussi une variabilité spatiale importante des sous-états écologiques basés sur les différents paramètres qui dépendent du choix des dates des campagnes de mesure et du point d'échantillonnage. Ces résultats ont aussi été utilisés pour estimer la représentativité d'une station de prélèvement. Les résultats de cette thèse i) confirment que le fonctionnement des plans d'eau de toute taille est complexe et que les processus physiques génèrent des hétérogénéités spatio-temporelles, ii) suggèrent que le vent et l'hydrodynamique influencent significativement l'abondance et la distribution spatiale du phytoplancton et que iii) ces hétérogénéités peuvent biaiser notre estimation du statut écologique des plans d'eau dans le cadre de la DCEThe quality of ecosystem services provided by lakes is related to the ecosystem structure and functioning. Protecting water bodies is therefore a global goal that requires a better understanding of their function, a monitoring and a water quality assessment. Explaining spatio-temporal heterogeneities of physico-chemical parameters and phytoplankton has been a recurrent ecological and hydrobiological issue. Understanding the dynamics of these heterogeneities is an essential prerequisite for objectively assessing, protecting and restoring freshwater ecosystems. Moreover, three-dimensional (3D) and taking into account and drivers of these heterogeneities are essential prerequisites for theoretical and applied limnology. Concerning the monitoring, spatio-temporal heterogeneities are responsible of uncertainties on the representativeness of the data versus the whole lake which might be questionable and needs to be verified. In Europe, the Water Framework Directive (WFD) initiated in 2000 defines a framework for managing and protecting water bodies in Europe. The classification of water bodies into ecological status is a key issue for the implementation of that framework. For lakes and reservoirs, the assessment of this status is based on biological, physico-chemical and hydro-morphological indicators. Physico-chemical and phytoplankton indicators are calculated based on four observations at an unique sampling station over the growing season, this evaluation being assessed one year for a six-year management plan. In this context, this thesis focuses on the complexity of lakes functioning and the capability of three-dimensional (3D) models to reproduce their functioning. The contribution of 3D models is presented i) for understanding the functioning of lakes of different sizes, ii) coupled to satellite observations, for studying of the influence of wind forcing and hydrodynamics on phytoplankton abundance and spatial heterogeneities, iii) in the context of the WFD, for assessing uncertainties in the lake ecological status assessment. To do that, two 3D models have been created and analyzed, one for Lake Créteil (42 ha) and another for Lake Geneva (580 km2). Lake Créteil 3D model was validated by using high frequency data recorded at three stations. It reproduces well the complex hydrodynamic functioning of the lake, its thermal structure, the alternation between thermal stratification episodes and mixing events, and internal waves. Lake Geneva 3D model was validated by using monthly and bimonthly data at two stations. It reproduces also properly the hydrodynamic functioning of the lake and the seasonal variability of biological and physico-chemical parameters. Simulation results highlight physical and hydrodynamic mechanisms responsible for the occurrence of seasonal hot-spots in phytoplankton abundance. In the context of the WFD, simulation results show also a strong spatial variability of lake ecological status depending on the timing of the four sampling dates as well as the location of the sampling station. These results were also used to assess to representativeness of sampling stations. The results of this thesis suggest that i) the functioning of lakes of different sizes is complex and physical processes generates spatio-temporal heterogeneities, ii) wind and hydrodynamics influence the abundance and the spatial distribution of phytoplankton et iii) spatio-temporal heterogeneities can bias our evaluation of lake ecological status in the WFD

Full textAbstract:
.This study is about the on-ground implementation of sustainable farm practices supported by policies and directives that form the core of the European Union’s sustainability policy. Its goal is to identify the blockers to effective policy implementation in order to improve the approach to sustainability in the agricultural sector. Exploring ways to engage local stakeholders in farm sustainability has been central to create a holistic understanding about the processes that drive practices in agriculture systems, and the extent to which these processes can be transformed. Sustainability in agriculture is a broad topic, hence this study focuses on one segment of sustainability namely the use and management of water resources in irrigated agriculture. The study’s final recommendations to improve policy design and interventions, however, are general and apply to the implementation of all sustainable farm practices. Practical effectiveness of EU policies and directives for sustainable agriculture is constrained by: a lack of evaluating criteria to measure policy impact and communicate progress; incentives for growers to commit to more than the minimum required, and continuous local renegotiation of proposed measures and programmes which have contributed to a weakening of initial policy proposals. This study demonstrates that policies serve different purposes for different people at different social and political levels. However, sustainability comes into practice on the farm, which is why farmers’ perspective about a sustainable agricultural sector and the proposed voluntary and mandatory policy measures is so important. Farmers’ perspectives are still missing elements in policy design for sustainable agriculture. Co-developing and testing technologies that are meant to deliver sustainability in practice, as well as farm decision support tools, are critical in engaging farmers and other local stakeholders in sustainability and to transform embedded practices and institutions. Collaboration across disciplines is also important to address environmental goals and farmers’ needs in order to extract substantial environmental benefits as well as a long term commitment from land managers in sustainability. This study shows that there are many insights to be gained and learnings to be extracted from scrutinizing policy interventions. It raises awareness about improving policy implementation by providing practical examples from case studies conducted in Spain and in Italy. These insights encourage the use of interdisciplinary approaches, including socio-technical approaches, for an integrated people and technology based perspective on natural resource management to better policy design and interventions and make sustainable agriculture real.

Full textAbstract:
The European Water Framework Directive commits the member states to achieve the good ecological status for all waterbodies. For this purpose on the level of the national states monitoring programs are established with the aim to verify the actual status by means of regular surveys. Already in the past remote sensing data in conjunction with methods of geospatial data analysis revealed the added value in terms of monitoring strategies regarding the European Water Framework Directive. Depending on the type of data they can be used for example for the determination of several parameters of rivers and streams. The present analyses show how it is possible to determine the parameter of width variation of small and medium rivers based on digital orthophotos. Because this parameter strongly depends on the geometric quality of the riverbank line, its determination is given particular attention. It turns out that mainly riparian vegetation has a large impact on the visibility of the riverbank line. In a multi-stage process different methods for the identification of affected areas are developed with the aim to reconstruct the true riverbank line in a second step. Finally these data form the basis for the determination of river width variations.

Full textAbstract:
Rivers are the lifelines of our environment. For this reason they are always in the focus of environmental studies. For the assessment of the ecological status of rivers the member states of the European Union have developed different monitoring programs and approaches. The shadowing of a river affects the temperature of the water and also the energy balance of the water body. Therefore changes in temperature also in uence the biological and chemical status of rivers and lakes. The main objective of this study is the simulation of the shadowing of a section of the river Freiberger Mulde for a full year. This ensures that effects of different sun positions over the year (azimuth, elevation) and also local topography conditions in the close environment of the river section are taken into account. For all analyses a digital surface model and a digital elevation model with a geometric resolution of 2 m is available. The result of this simulation is a raster layer which represents the theoretical annual hours of shadowing of the river section. The results indicate a decrease of illumination of partly more than 80 %. In future this information can be expanded by means of further affecting factors such as the consideration of the phenological status of deciduous trees in the riparian zone.

Full textAbstract:
The vegetation in the riparian zone of a watercourse in fluences the water state with multiple factors, first via direct substance discharge and secondly via shadow casting on the water surface. Shadowing directly regulates the solar radiant energy arriving at the water surface. Solar radiation input to aquatic environments is the most important abiotic factor for aquatic flora and fauna habitat development. Thus, to adequately asses the ecological state of water courses it is necessary to quantify the solar surface irradiance E (W=m2) arriving on the water surface. When estimating the solar surface irradiance the complex coherence between incoming solar radiation, atmospheric in uences, and spatial-temporal geometries need to be investigated. This work established a work flow to compute the solar surface irradiance for water bodies using different remote sensing data. The work flow was tested on regional level for a section of the river Freiberger Mulde, Saxony, for the year 2016. Product of the calculations is a map visualising the annual sum of the solar surface irradiance (kWh=m2) arriving on the Freiberger Mulde water surface and the surrounding terrain.

Full textAbstract:
The diversity of habitats in water bodies like rivers is characterised by the status of morphological and hydrological conditions. The good ecological status of water bodies is claimed in the EuropeanWater Framework Directive. For the assessment of this status the hydro-morphology is one of the most important supporting components for the classification of the ecological status of water bodies. Therefore the periodical monitoring is a mandatory measure in the scope of the European Water Framework Directive. Regarding the so called overview-method of the LAWA (German Working Group on water issues of the Federal States and the Federal Government represented by the Federal Environment Ministry) the use of remote sensing data and remote sensing methodologies becomes more important. Therefore remote sensing data on different scales (satellite, aerial photographs) as well as other topographic information (ATKIS) and a high resolution DTM are merged into an integrative process of analysis using remote sensing and GIS methodology. The analyses ared focused on two parameters. First, a detailed landuse classification based on LANDSAT satellite data is performed for whole catchment of a small river. The results show significant increase of urban areas close to the river. The second analyses deals with the determination of river curvature and introduces the use of a quasi-continously representation of the river. An additional challenge is the chosen study area of a low mountain range river. While large rivers are clear visible in remote sensing data, the usability and transformation of the well-established algorithms and work ows to small rivers need a further substantial research.

Full textAbstract:
The European Water Framework Directive (WFD; 2000/60/EC) was incorporated into the Swedish legislation in 2004 through the ordinance Förordningen om förvaltningenav kvaliteten på vattenmiljön (SFS 2004:660). The objective is that all water bodies shall reach a good status by the year 2015. In Sweden the comprehensive plans of the municipalities can play a large role in reaching these goals. A comprehensive plan deals with the long term water and land use of the municipality, which can facilitate an early consideration of water management in the planning process of the municipality. In Sweden five river basin districts have been established in accordance with the Water Framework Directive. The focus of this study is on the Northern Baltic Sea river basin district. Action strategies have been created for each river basin district, dictating what measures the authorities, among them the municipalities, need to take. The purpose with this study is to find out to what extent the municipalities have taken the action strategies regarding the Northern Baltic Sea river basin and the water quality standards set in Förordningen om förvaltningen av kvaliteten på vattenmiljön (SFS 2004:660) into account when working with their comprehensive plans. The study also sheds light on the municipalities’ view on the demands made on them and what actions can facilitate the working process. The study was made in three parts; a survey, literature studies and interviews. An overall study of all the municipalities in the county of Stockholm was made and three were selected for an in-depth study. The results of the study show that the demands on the municipalities have not been met due to lack of knowledge. The municipalities are aware of the existence of the Water Framework Directive but find it hard to interpret the environmental quality standards and the action strategies. The municipalities wish for a clearer legal definition of the environmental quality standards and a better definition of how the implementation of the action strategies can be made. The municipalities are asking for a clarification of the demands they can make on other organizations and of the demands made on them by the county boards and the River Basin District Authorities.

Full textAbstract:
Shallow lakes are an important ecological and socio-economic resource. However, the impact of human pressures, both at the lake and catchment scale, has precipitated a decline in the ecological status of many shallow lakes, both in the UK, and throughout Europe. There is now, as direct consequence, unprecedented interest in the assessment and monitoring of ecological status and trajectory in shallow lakes, not least in response to the European Union Water Framework Directive (2000/60/EC). In this context, the spatially-resolving and panoramic data provided by remote sensing platforms may be of immense value in the construction of effective and efficient strategies for the assessment and monitoring of ecological status in shallow lakes and, moreover, in providing new, spatially-explicit, insights into the function of these ecosystems and how they respond to change. This thesis examined the use of remote sensing data for the assessment of (i) phytoplankton abundance and species composition and (ii) aquatic vegetation distribution and ecophysiological status in shallow lakes with a view to establishing the credence of such an approach and its value in limnological research and monitoring activities. High resolution in-situ and airborne remote sensing data was collected during a 2-year sampling campaign in the shallow lakes of the Norfolk Broads. It was demonstrated that semi-empirical algorithms could be formulated and used to provide accurate and robust estimations of the concentration of chlorophyll-a, even in these optically-complex waters. It was further shown that it was possible to differentiate and quantify the abundance of cyanobacteria using the biomarker pigment C-phycocyanin. The subsequent calibration of the imagery obtained from the airborne reconnaissance missions permitted the construction of diurnal and seasonal regional-scale time-series of phytoplankton dynamics in the Norfolk Broads. This approach was able to deliver unique spatial insights into the migratory behaviour of a potentially-toxic cyanobacterial bloom. It was further shown that remote sensing can be used to map the distribution of aquatic plants in shallow lakes, importantly including the extent of submerged vegetation, which is central to the assessment of ecological status. This research theme was subsequently extended in an exploration of the use of remote sensing for assessing the ecophysiological response of wetland plants to nutrient enrichment. It was shown that remote sensing metrics could be constructed for the quantification of plant vigour. The extrapolation of these techniques enabled spatial heterogeneity in the ecophysiological response of Phragmites australis to lake nutrient enrichment to be characterised and assisted the formulation of a mechanistic explanation for the variation in reedswamp performance in these shallow lakes. It is therefore argued that the spatially synoptic data provided by remote sensing has much to offer the assessment, monitoring and policing of ecological status in shallow lakes and, in particular, for facilitating the development of pan-European scale lake surveillance capabilities for the Water Framework Directive (2000/60/EC). It is also suggested that remote sensing can make a valuable contribution to furthering ecological understanding and, most significantly, in enabling ecosystem processes and functions to be examined at the lake-scale.

The Revised Bathing Water Directive will have a major impact on the way that Competent Authorities assess water quality. It requires work in various disciplines to be streamlined into delivering the methods and approaches needed to deliver the requirements of the Directive. To achieve this, Competent Authorities will have to engage effectively with all stakeholders and embrace the principles of Integrated Coastal Zone Management. This does not currently happen. This research assessed the legislative and managerial development of the revised Bathing Water Directive proposal COM 581 and developed methods and approaches to support this, through the production of an interdisciplinary Bathing Water Management Framework (BWMF). This led to the creation of biological monitoring and communication methods that could deliver the requirements of the revised Directive. This research showed that the revised Bathing Water Directive will require Competent Authorities to work with others and look at novel ways of gathering and communicating information required for the Directive; including biomonitoring and emerging communication technologies. This will require the UK and Europe as a whole to embrace the principles of Integrated Coastal Zone Management (ICZM). This research has shown that interdisciplinary research can be successful in answering complex, cross-cutting issues such as how to develop a holistic overview of Bathing Waters. When compared to a monodisciplinary approach, this research has advanced in several disciplines and also created a brand new intellectual space in the form of the framework. Whilst the interdisciplinary outputs are powerful the research has also delivered the article requirements of the Directive.

Full textAbstract:
The development of the European water policy has been in a continuous improvement process during the last fifty years. The adoption of Water Framework Directive (WFD) enabled the consolidation of a fragmented policy to comprehensive approach with a focus on sustainability. The floods Directive was developed as acomplement to the WFD and promoted their integration. However, several opportunities have been identified in the implementation and in achieving integration. This paper identifies integration gaps faced by practitionersand develops an assessment framework which can be used by diverse stakeholders from policy makers to water users to understand the degree of integration in a systematic way. Indicators within the framework can shed light on the progress and optimize the development of action plans to address integration gaps and achieveefficiency gains. Although not a remedy for the complex challenges, establishing measuring systems is a first step to ensure integration of current and future directives.

Current approaches to sampling and analysis are thought to be unsuitable for investigative monitoring under the auspices of the European Union’s Water Framework Directive. During this study, new sampling and analytical techniques were developed and tested that provide a ‘toolkit’ that can be utilised by most laboratories engaged in regulatory analysis of water samples. The techniques developed include; i) Targeted screening methodology based on passive sampling in-conjunction with comprehensive two-dimensional chromatography mass spectrometry was developed and successfully applied to the broad-scope detection and determination of non-polar emerging pollutants and related contaminants in environmental waters. This method was found to be superior to existing approaches based on spot sampling and one dimensional gas chromatography. ii) Modifications to the Chemcatcher® passive sampler to allow for the sampling of polar pollutants present in the water environment. Statistical analysis of the data obtained demonstrated that sampler performance was equivalent to that of the established POCIS passive sampler but with greater physical robustness together with simplified preparation and extraction procedures. iii) Targeted screening methodology based on modifications to the existing Chemcatcher® passive sampler in-conjunction with liquid chromatography-high resolution mass spectrometry techniques for the identification of polar pharmaceutical residues present in the effluents of waste water treatment plants located in south west Wales. Identification of analytes was strengthened through the development, validation and application of a novel accurate mass data-independent acquisition method and the high degree of analyte identification assurance obtained confirmed it to be analogous to traditional collision-induced dissociation transitions. iv) The targeted application was supplemented through the development and application of a novel in silico methodology for retention time prediction which was successfully used to identify additional compounds in an extract obtained from a Chemcatcher passive sampler, and, thus, the preliminary identification of potential emerging contaminants. Overall, this work has furthered the knowledge and capability of the sampling and analysis of existing and newly emerging contaminants in environmental waters.

Water protection proves to be a difficult task, whether it is dealt with through legislation or the implementation of a process to reduce further pollution. This study considers how the issue of water pollution from nitrates in agricultural practices has become better understood through the reforms of the common agriculture policy (CAP) and the enactment of various regulations and directives by EU. The implementation of the EC Nitrate Directive is a main focus of this study because it was a major movement towards protecting water against pollution from agriculture, and an important step in implementing the Water Framework Directive. The implementation process is analyzed from both a formal and practical perspective, along with a discussion of the difficulties that arose in the implementation phase. There is a focus on the implementation of the Nitrate Directive in UK, with an emphasis on England as a case study. The study finds that if the distribution of responsibilities (planning, regulating, implementing, and reporting) is shared between national, regional and local bodies, the compliance with political regulations becomes easier. It is also concluded that rearrangements of the existing institutions are necessary to reduce costs, exchange new ideas that could translate to regulative ideas, and create an atmosphere of trust between regulators and implementers. It can be concluded from this study that, despite the traditional centralization of governments, England has taken several steps towards integrating institutions and has tried to be open and responsive to the local communities. Finally, there are several lessons that can be learned from the UK’s approach to control nitrate pollution, which are discussed and outlined in the conclusion of this study.Water protection proves to be a difficult task, whether it is dealt with through legislation or the implementation of a process to reduce further pollution.

Full textAbstract:
The implementation of the EU Water Framework Directive (2000/60/EC) (WFD), enacted to monitor and recover the quality of water bodies, is a good example of catchment management requiring a wider scope of understanding with regard to the chemical, ecological and quantitative status of river catchments. It has caused water management to shift from a local to a river basin scale and therefore requires a better understanding of emission sources of dangerous substances and their contribution to water quality at the catchment level. Metals include dangerous substances of continued and growing concern. The hazardous properties of metals reflect their ability to substitute for essential elements in biological systems, resulting in a disturbance of the biological functions of animals and humans. This thesis aimed to identify ways of assessing sources of metals at the catchment level for the implementation of the WFD. Different approaches were proposed to estimate impacts of emission sources on levels of metals in water bodies. Potential anthropogenic sources of metals and metalloids in receiving waters were identified at the catchment level. Of the metal sources, effluents from wastewater treatment plants, sediments in a water body and diffuse metal sources were selected in order to further evaluate their contributions to the quality of water bodies, using or developing simple methods to estimate these. Case studies demonstrated the effectiveness and reliability of the calculations used. Overall findings of the work highlighted the need to identify all the pressures of pollutant inputs and to assess their relative importance to the deterioration of water quality for compliance with the WFD. To this end, it is recommended that source assessment should be incorporated into the process of river basin management under the WFD. Source assessment can facilitate the performance of water management stages and the improvement of the quality of surface water bodies.

Full textAbstract:
Water management is undergoing a transformation towards integration, source control and ecological thinking. In the EU, the Water Framework Directive can be considered as a driver towards this new approach to water management. Innovations are deemed necessary to deliver this ideal of water management. In this thesis efforts by water sewerage companies in England & Wales to rectify agricultural pollution at source are viewed as an organisational innovation towards more sustainable water management. These source control interventions can help achieving the goals of the Water Framework Directive by reducing diffuse pollution from agriculture, fostering participation in water management and by reducing overall cost of implementation. This thesis contributes to understanding the process of change in water management by developing a model of the innovation-decision process. Insights about how innovation and therefore change can be influenced is generated by applying this model to the process of source control intervention adoption by water and sewerage companies. This research employed a flexible research design using comparative case studies. Each of the 10 water and sewerage companies in England and Wales represented an individual case. Data were collected in two phases using semi-structured interviews with selected water and sewerage company representatives. Thematic analysis, recurrence counts and content analysis were applied to analyse interviews. It was found that water companies are likely to contribute towards integrated approaches to water management, since there is a trend to adopt source control intervention. Change in water management is influenced by the interaction of factors from the domains: ‗Natural-Physical‘, ‗Organisational Characteristics‘, ‗Regulatory- Institutional‘ and ‗Innovation Attributes‘. The rate of change by water and sewerage companies is governed by a combination of asset characteristics, environmental state changes and the funding cycle. Furthermore, innovation is triggered by direct regulation and regulation that requires the gathering of information. Contrary to this flexible or framework regulation performs better in guiding the direction of change.

L’extraction de motifs partiellement ordonnés à partir de séquences temporelles de pressions physico-chimiques précédant un état biologique a été réalisée. Ces motifs temporels permettent d’identifier une partie des pressions en cause dans un état écologique dégradé ou non, de préciser l’importance de la durée des séquences avant l’évaluation de l’état biologique, d’identifier les altérations caractéristiques à l’échelle d’une hydro-écorégion. A terme nous envisageons d’élargir ces motifs aux pressions hydromorphologiquesData from the assessment of river are big data, with complex relationships. Unsupervised data mining methods can be applied on them and give relevant results for their management, if a close collaboration exists between hydroecologists and computer scientists. The extraction of partially ordered patterns from temporal sequences of physicochemical pressures preceding a biological state has been achieved. These temporal patterns allow to identify a part of the pressures involved or not in a degraded ecological status, to specify the importance of the sequences time-length before a biological assessment, to identify the characteristic pressure categories at a regional scale. To go further, we plan to extend these patterns to hydromorphological pressures

Full textAbstract:
The Water Framework Directive (WFD, 2000/60/EC) was introduced in 2000. In implementing the WFD in Sweden expert knowledge in areas relating to the WFD was much needed resulting in establishment of national water management authorities, as the five water authorities, boarded in appointed county administrative boards across the country. As much noted in literature, uncertainties appear when implementing the WFD. Previous literature,with the exception of e.g. Raadgever et al (2011), Brugnach et al (2008) and Sigel et al (2007 and2010), has not put much focus on the types of uncertainty experienced by water management officials working with the implementation of the WFD on a daily basis. There are also few studies in Sweden, such as Gipperth & Elmgren (2010), Hammer et al (2011) and Entson & Gipperth(2010), touching upon the subject although not entirely focusing on practical experiences of uncertainty. Therefore, the aim of this study is to reveal the types of uncertainties experienced by water management officials from: SMHI, the county administrative board in Östergötland and Bothnia Bay, the water authority in the Southern Baltic Sea district, the Northern Baltic Sea and the North Sea, as well as the SEPA. In analysing the empirical data, six types of uncertainties emerged. They showed that water management officials experienced uncertainties in interpreting the WFD e.g. recommendation and manuals from supervisory authorities, measurement techniques, the typology of water bodies, what methods to use in e.g. assessments, knowing the effects of action programmes and lack of data ordata deficiency. In combating these uncertainties, the water management officials used communication as an strategy. Furthermore, responsibility in pointing out uncertainties and ways of reducing uncertainties was also seen as ways of handling uncertainties.

For a meaningful discussion of the effectiveness of ecological objectives and ecological quality standards, their terms and purposes must be examined and clarified. This study explores the terms and content of ecological quality objectives and ecological quality standards, based on the Water Framework Directive’s legal conceptualization of ‘ecological status’. This exploration is accomplished by analysing and describing the Water Framework Directive’s ‘ecological status’ aspect from a legal-ecological perspective. The analysis of ‘ecological status’ and its main constructs forms the basis for a possible alternative form of regulation, which addresses the shortcomings identified in the analysis.

Full textAbstract:
Doutoramento em EconomiaThis work is a contribution to the study of how the Portuguese water industry can meet the goals of cost recovery and water use efficiency set out by the Water Framework Directive. We describe the Portuguese water and wastewater tariffs implemented from 1998 to 2005 and the cost recovery levels for that period. The tariff revenues collected by the water utilities are insufficient to meet the financial costs of their activities, especially regarding wastewater, and the situation has worsened in recent years. We review the existing water pricing models, highlighting some important results like the fact that efficiency requires marginal cost pricing, which may not be feasible while respecting a revenue requirement. It is not evident whether the best scheme is a two-part tariff or some other pricing mechanism like increasing block tariffs (IBT), which are abundantly used in Portugal. We incorporate the scarcity cost associated with insufficient water availability into the optimal tariff design. We show that when both demand and costs respond to climate factors, increasing marginal prices may come about as a combined result of scarcity and customer heterogeneity when the fixed charge is only allowed to cover fixed costs and the utility is required to maintain a balanced budget. Ultimately, the choice of tariff schedule design is dependent on the behavior of the price-elasticity of demand. We estimate the Portuguese residential water demand and show that the resulting recommended tariff schedule hinges crucially on the choice of functional form. After the proper specification tests, a choice between a semilogarithmic lin-log and a double-log specification is left undecided, which does not prove the superiority of IBT, but also does not enable its dismissal. We also estimate a multi-output cost function for the Portuguese water industry at the retail level. We find diseconomies of scale and scope for the average water utility. Both types of economies are more likely to exist for utilities with a large customer base.
Este trabalho é um contributo para o estudo da melhor forma de atingir os objectivos de recuperação de custos e eficiência do sector da água em Portugal traçados pela Directiva-Quadro da Água. Nele se descrevem as tarifas de água e saneamento aplicadas entre 1998 e 2005 e os níveis de recuperação de custos nesse período. As receitas tarifárias angariadas pelas entidades gestoras mostram-se insuficientes para cobrir os custos da sua actividade, especialmente no que diz respeito ao saneamento e a situação tem vindo a piorar nos últimos anos. A literatura sobre modelização da determinação dos preços da água é revista, salientando alguns resultados importantes como o facto de a eficiência exigir que o preço seja equiparado ao custo marginal, algo que pode não ser possível em simultâneo com restrições de manutenção de orçamentos equilibrados. Não é evidente qual o melhor tipo de tarifário a adoptar, a combinação de uma componente fixa com um preço volumétrico constante ou outro esquema alternativo como os tarifários crescentes por blocos, largamente utilizados em Portugal. O custo de escassez é incorporado na definição do tarifário óptimo. Demonstra-se que quando a procura e a oferta reagem ambas a factores climatéricos, preços marginais crescentes podem resultar da combinação da escassez de água com a heterogeneidade dos consumidores em situações em que à componente fixa da tarifa apenas é permitido cobrir os custos fixos e é exigido à entidade gestora que mantenha um orçamento equilibrado. A escolha do melhor tarifário depende fundamentalmente do comportamento da elasticidade-preço da procura. Neste trabalho estimamos a procura residencial de água em Portugal e mostramos que a recomendação sobre o melhor tipo de tarifário depende crucialmente da escolha da forma funcional da procura. Da realização dos testes de especificação adequados, resulta uma escolha inconclusiva entre as formas funcionais semilogaritmíca (lin-log) e loglinear, o que não permite provar a superioridade dos preços crescentes por escalões, mas também não os rejeita. Estima-se também uma função de custos multi-produto para o sector de abastecimento de água e saneamento português em baixa. Para a entidade gestora de dimensão média existem deseconomias de escala e de gama. Os dois tipos de economias tendem a existir para entidades com maior número de consumidores.

The Water Framework Directive requires reduced environmental impacts from human activities and for the assessment of the non-market benefits of pollution remediation schemes. This policy shift has exacerbated the research problems surrounding the physical, social and economic consequences of the relationship between land use and water quality. This research seeks to quantify the major socio-economic and environmental benefits for people which may arise as riverine pollution is reduced. To achieve these aims this research integrates primary data analyses combining choice experiment techniques with geographical information system based analyses of secondary data concerning the spatial distributions of riverine pollution. Current knowledge on the microbial quality of river water, measured by faecal indicator organism (FIO) concentrations and assessed at catchment scale, is inadequate. This research develops generic regression models to predict base- and high-flow faecal coliform (FC) and enterococci (EN) concentrations, using land cover and population (human and livestock) variables. The resulting models are then used both to predict FIO concentrations in unmonitored watercourses and to evaluate the likely impacts of different land use scenarios, enabling insights into the optimal locations and cost-effective mix of implementation strategies. Valuation experiments frequently conflate respondents’ preferences for different aspects of water quality. This analysis uses stated preference techniques to disaggregate the values of recreation and ecological attributes of water quality, thereby allowing decision makers to better understand the consequences of adopting alternative investment strategies which favour either ecological, recreational or a mix of benefits. The results reveal heterogeneous preferences across society; specifically, latent class analysis identifies three distinct groups, holding significantly different preferences for water quality. From a methodological perspective this research greatly enhances the ongoing synthesis of geographic and economic social sciences and addresses important policy questions which are of interest to a variety of stakeholders, including government departments and the water industry.

Full textAbstract:
In Sweden, EU: s Water Framework Directive led to an investigation that started in April 2012 by the Swedish government, called Vattenverksamhetsutredningen freely translated to "Water Activities Survey", with the purpose to investigate the Environmental Code’s rules concerning water activities and water plants. The survey is divided into 3 reports, two sub-reports and a final report. One of the sub-report is focused on Swedish hydropower and the investigators found that many hydropower plants have old permits. One suggestion in the survey was to reconsider old permits so they would become consistence with today’s Environmental Code. There have been discussions regarding whether Sweden will lose much of its electricity production from hydropower as an outcome if the survey’s suggestions becomes reality. The aim with this literature study is to investigate how the EU: s Water Framework Directive and the Water Activities Survey will affect Swedish hydropower and if there will be a decrease in electricity production as an outcome if the suggestions made in the survey becomes reality. The results in this literature study shows that there will probably be a decrease in production for Swedish hydropower, but with how much is hard to say because the Swedish government has not yet decided what they will do with the suggested actions in the Water Activities Survey. A comparison is done with Sweden’s import and export statistics between the years 2001-2014 with a predicted loss of 13 TWh per year, which is a number taken from a survey made by Vattenfall. A comparison with a loss of half of 13 TWh per year is also done. Between the years 2001 and 2014 Sweden imported electricity 6 out of 14 years and exported electricity 8 out of 14 years. If adding the predicted loss of 13 TWh per year to the import and export statistics, Sweden would have had to import electricity 12 years and export 2 years. If adding a loss of 6.5 TWh per year Sweden would have had to import electricity 8 years and export 6 years. The conclusions is that Sweden will have to import a lot more electricity if only looking at import and export statistic if the loss of electricity is between 6.5-13 TWh per year.

This is not only a problem for developing countries, and there can also be variations within countries. The municipality of Gotland has a development program called Vision Gotland 2025, with goals for growth and sustainable development. The aim of this study is to examine whether the use and management of water resources on Gotland and Vision Gotland 2025 is conformed to the Water Framework Directive and the Ecosystem Approach in terms of sustainability. Focus is on the quantitative aspects of water supply. The study has mainly been done by studying publications from the authorities concerned. Although annual precipitation in general is enough to provide fresh water for the population, water shortage occurs in some areas during the summers. Three of the four main catchment areas on Gotland have unsatisfactory quantitative status, and is likely to have so also when the time limit of the next evaluation is due in 2015. Since both the population and tourism is presumed to increase, according to Vision Gotland 2025, the conclusion drawn is that the use of water resources is not sustainable, even though the management per se does conform to the ecosystem approach.

Full textAbstract:
Drastic reductions in greenhouse gas (GHG) emissions are needed in order to mitigate the effects of climate change. The European Union (EU), a leader in climate change mitigation, has adopted an ambitious strategy to achieve its mitigation goal. A piece of this strategy is the Renewable Energy Directive. The Directive establishes mandatory renewable energy targets for member states. Cognizant that in order to achieve the target of 10% of final energy consumption in the transport sector member states would have to rely heavily on biofuels, the EU, in the spirit of sustainable development, included in the Directive sustainability criteria for biofuels. The criteria were needed because, although biofuels can be carbon neutral and an effective replacement for fossil fuels, the production of biofuels can have serious environmental and socio-economic consequences. This thesis concludes that the Directive will not result in the sustainable production of biofuels. This conclusion is based on the principled lifecycle assessment of the Directive and its framework. This approach is a combination of core principles of sustainable development – integration, equity, precaution and polluter pays – and of the basic tenets of lifecycle assessment, a methodology designed to measure the lifecycle impacts of a product. Due to the reliance by member states on first generation biofuels, biofuels produced under the Directive’s regime are not likely to reduce GHG emissions compared to fossil fuels, and are likely to increase water pollution, the loss of biodiversity and food insecurity. The negative impacts of biofuels production are caused mainly by the agricultural production of feedstocks, especially through indirect land-use change. Furthermore, the cost of pollution is not internalized by the regime and biofuels subsidies are not linked to environmental concerns. Therefore, the lifecycle impacts of EU biofuels production do not accord with core principles of sustainable development. Only second and third generation biofuels, which are not yet available on a large-scale, seem to have the potential to be sustainable.Law, Peter A. Allard School of

Full textAbstract:
The collection of data though environmental monitoring is critical to the success of integrated water management, therefore this PhD investigated its role in the management of surface water bodies, providing recommendations for the implementation of the Water Framework Directive (WFD). The monitoring requirements of the WFD have been reviewed and a comparison to previous arrangements in England and Wales was made. Findings demonstrated the challenges associated with a transition from established networks to those that support more integrated approaches. Using a river basin in England the role of monitoring in both ecological and chemical assessments was evaluated. Results revealed the need to evaluate data produced and ensure that networks are risk based and adaptive, both responding to and aiding understanding of the processes that determine water quality. The need to supplement regulatory monitoring with technical analyses to understand source-pathways-receptor models for contaminants, along with the need to combine chemical and biological assessments so that the risks to ecosystems can be identified was highlighted. The use of data to enable the identification and management of the pressures on surface water bodies was then explored. It was demonstrated that a systems approach to understanding the interactions between the abiotic, biotic and functioning of the ecosystem was needed so that pressures could be managed sustainably. The need to monitor the effectiveness of measures implemented to improve water bodies was also highlighted, with examples of both the structural and functional elements that could be used provided. Finally, recommendations on the communicating of data to stakeholders, along with their involvement in the management and monitoring of water bodies, were made. This work highlights the potential role monitoring has in the successful implementation of the WFD, demonstrating the need for review and flexibility in monitoring networks, along with frameworks which enable monitoring to contribute to understanding of ecosystems and allow collaboration and knowledge sharing within decision making processes.

Full textAbstract:
The Water Framework Directive (WFD) has the stated objective of delivering good status (GS) for Europe’s surface waters and groundwaters. But meeting GS is cost dependent, and in some water bodies pollution abatement costs may be high or judged as disproportionate. The definition and assessment of disproportionate costs is central for the justification of time-frame derogations and/or lowering the environmental objectives (standards) for compliance at a water body. European official guidance is discretionary about the interpretation of disproportionate costs which consequently can be interpreted and applied differently across Member States. The aim of this research is to clarify the definition of disproportionality and to convey a consistent interpretation that is fully compliant with the economic requirements of the Directive, whilst also being mindful of the principles of pollution control and welfare economics theory. On this basis, standard-setting derogations should aim to reach socially optimal decisions and be judged with reference to a combination of explicit cost and benefit curves – an application of Cost-Benefits Analysis - and financial affordability tests. Arguably, these tools should be more influential in the development of derogation decisions across member states, including Scotland. The WFD is expected to have extensive effects on Scottish agriculture, which is faced with the challenge of maintaining its competitiveness, while protecting water resources. Focusing the analysis on the socio-economic impacts of achieving water diffuse pollution targets for the sector, a series of independent tests for the assessment of disproportionate costs are proposed and evaluated. These are: i) development of abatement cost curves for agricultural Phosphorus (P) mitigation options for different farm systems; ii) a financial characterisation of farming in Scotland and impact on profits of achieving different P loads reductions at farm level are investigated in order to explore issues on "affordability" and "ability to pay" by the sector; and iii) an investigation of benefits assessment using discrete choice modelling to explore public preferences for pollution control and measure non-market benefits of WFD water quality improvements in Scotland. Results from these tests provide benchmarks for the definition of disproportionate costs and are relevant to other aspects of the economic analysis of water use in Scotland. This study helps to clarify the nature of agricultural water use and how it leads to social tradeoffs with other non agricultural users. Ultimately, this perspective adds to the debate of how and where water is best employed to maximize its value to society.

Full textAbstract:
Uncertain and complex environmental legislation governing the management of water resources has presented significant challenges to those responsible for identifying investment options to manage potable water supplies. This study aimed to develop a decision support process to enable a UK water company to understand and characterise the complex and uncertain implications of the Water Framework Directive (WFD) on the management of potable water supply. A flexible, exploratory and participatory approach was adopted, and included a central reference group comprised of managers representing different departments within the water company. Semi-structured interviews, informal discussions, focus groups, field visits, water company data, academic and legislative documentation, as well as UK water sector literature and observations by the researcher provided data which informed the criteria for and the population of a new Bayesian Network (BN) based Hybrid-Decision Support Process (Hybrid-DSP). Using BNs as a basis for decision support allowed the integration of diverse variables, as well as identifying and representing the relationships between them. The visual representation that BNs provided of the interrelationships between the variables, facilitated organisational learning in relation to the implications of the WFD for potable water management, which led to clearer identification of potential organisational responses. This study demonstrates the practical implications for the use of BNs within a water company in the UK. Furthermore a new BN based Hybrid-DSP has been developed through this study, which offers a systematic and holistic template to identify and analyse water company responses to the implementation of environmental legislation.

Full textAbstract:
The objective of our thesis was to conduct a pilot study to evaluate if an Extended Producer Responsibility (EPR) for textiles in the EU could be a socioeconomically beneficial policy to complement the EU Waste Framework Directive’s amendment of separately collected textiles. The aim was to investigate if the policy could achieve increased circular design of textiles as well as if it could work as a management plan for the increased collection rates. The evaluation was made with a Cost-Benefit Analysis, using the French EPR-system for textiles as a base. It was further complemented with previously conducted research of EPR-systems for other waste streams in the EU, as well as by previously conducted investigations for other national implementations of producer responsibilities for textiles. In additional support, we used data for differences between the member states in the European Union and conducted an expert interview. The EPR was compared to a situation where the municipalities in the member states would instead be responsible for the separate collection of textiles. The result of our investigation illustrates how both alternatives generate a net-loss, the Municipal Responsibility with - €7,611,410,291 and the Extended Producer Responsibility with - €6,012,109,341 during the first year of implementation. The EPR alternative generates a lower net-loss during the first three years of implementation. The producer responsibility is however the less beneficial alternative four years after implementation, since the decreased opportunity cost of labour generated through the hiring of unemployed assumed under the producer responsibility is deducted. The producer responsibility does however generate benefits through clearly defined responsibility of the textiles placed on the European market and gives incentives for increased fibre-to-fibre recycling and for increased durability of textiles. The initiative therefore generates both higher quantifiable-and non-quantifiable, environmental benefits than the alternative. We conclude that an Extended Producer Responsibility should be further examined as a complement to the regulation of separate collection of textiles, to reach an increased circular textile industry.

Full textAbstract:
The Water Framework Directive (WFD) constitutes the most recent and most comprehensive effort of the European Commission to respond to water quality problems across Europe. While member state authorities are encouraged to comply with the Directive's participatory require- ments in order to increase the effectiveness of implementation, the inclusion of public actors into-- water policy making introduces also legitimacy complications. Dominant discourses in environ- mental resource management have so far failed to account for the complexity within legitimacy and have tended to present participation as a managerial means to, enhance the effectiveness of implementation proceedings, After a theoretical engagement with this complexity, the research analyses within a case study the legitimation practices employed by the Environment Agency, as the nominated 'competent authority' charged with implementing the WFD in England and Wales. Participatory river basin planning procedures were observed over a period of two and a half years and interviews were conducted with participating actors on a catchment, river basin district and national level. The thesis examines how legitimation was performed by the author- ity, how this constituted the planning process and how participants reacted towards this. This research highlights how a non-departmental public body's legitimation practices displace the po- litical element from participatory river basin planning and force actors to engage into strategies outside of the formalised engagement procedures in order to realise their objectives. I conclude that we have to give recognition to the hybrid, multiple, and fluid nature of legitimation practices in order to avoid the perils of technocratic approaches while paying attention to the politics of environmental problems through more local and issue based engagement procedures.

Full textAbstract:
Mestrado em MicrobiologiaFreshwater ecosystems have been suffering severe degradation and loss of biodiversity, caused by human disturbances such as agriculture, industry, mining, urban development and climate changes. Therefore, the European Union reached an agreement and implemented the Water Framework Directive (WFD), with the main goal of reach a good ecological status in all water bodies. However, WFD is very complex, methodologies are time-consuming and costly. Thus, the main objective of this study is to develop a rapid and cost-effective approach, by studying the bacterial community composition by flow cytometry, as a complementary methodology to WFD. To achieve this, we study 3 sampling sites at Caima River along the seasons (winter, spring and summer), with different levels of environmental impacts (Nascente- river source- with little impact, Bustelo- downstream WWTP and Palhal- exposed to mine drainage), applying first the WFD criteria and then multivariate analysis for macroinvertebrate, periphyton and bacteria communities. Physico-chemical, metals and bacteria samples were collected from the water column and sediment river bottom, showing that in all the parameters (with some exceptions) and metals the concentrations were higher in sediments. Results showed that not always the macroinvertebrate and periphyton communities were sensitive to an increased nutrient input, resulting in an ecological status higher than expected. On the other hand, community structure analysis for macroinvertebrates and periphyton was very discriminatory, associating high levels of nutrients and metals with more tolerant organisms in impacted sites, and sensitive organisms with high levels of dissolved oxygen corresponding to pristine environments. Bacteria community analysis revealed a clear separation of LNA and HNA bacteria in sediment according to the different environmental stress, being possible to dissociate the majority of the impacted sites from the clean sites, being HNA a good indicator of contamination. These results revealed that bacteria community in sediments has more reliable data about the impacts that a freshwater ecosystem can suffer. The discriminating power of bacteria community analyzed by FCM provided good responses, although, further investigations are needed to confirm the feasibility of this new method, as a complementary tool in the water quality assessment.
Os sistemas aquáticos de água doce têm vindo a sofrer uma severa degradação e perda de biodiversidade, derivado de atividades humanas como a agricultura, indústria, atividades mineiras desenvolvimento urbano e alterações climáticas. Assim, a União Europeia implementou a Diretiva Quadro da Água (DQA), com o principal objetivo de atingir o bom estado ecológico em todas as massas de água. No entanto, a DQA revelou ser bastante complexa, com metodologias muito morosas e dispendiosas. Com este estudo, pretende-se desenvolver uma metodologia rápida e económica, estudando a composição da comunidade bacteriana por citometria de fluxo, como ferramenta complementar à DQA. Para a concretização deste trabalho, foram estudados 3 locais do rio Caima com diferentes tipos de impactos: a nascente – local de referência; Bustelo - a jusante de uma estação de tratamento de águas residuais e o Palhal - com escorrências provenientes de uma mina desativada, no inverno, primavera e verão aplicando a metodologia estabelecidas pela DQA usando os macroinvertebrados e perifiton como comunidades biológicas estudadas. Adicionalmente foi aplicada a análise multivariada aos dados recolhidos por citometria de fluxo à comunidade de bactérias da coluna de água e dos elutriados dos sedimentos e aos resultados das comunidades de macroinvertebrados e perifiton obtidos da DQA. No geral, os parâmetros físico-químicos, e as quantificações de metais mostraram valores mais elevados nos elutriados dos sedimentos do rio, do que na coluna de água mostrando a importância da análise desta matriz que não está contemplada na DQA. Resultados sensu DQA mostraram que nem sempre as comunidades de macroinvertebrados e perifiton foram concordantes na resposta aos diferentes tipos de impactos e que a qualidade ecológica dos locais avaliados foi melhor do que era expectável. Por outro lado, a análise multivariada das comunidades de macroinvertebrados e perifiton foi bastante discriminatória, associando elevados níveis de nutrientes e metais com organismos mais tolerantes, que se encontram em locais mais impactados, e organismos sensíveis com altos níveis de oxigénio dissolvido em locais mais pristinos. A análise da comunidade bacteriana revelou uma distinta separação entre bactérias LNA e HNA nos sedimentos, de acordo com os diferentes stresses ambientais, sendo HNA, nos sedimentos, um ótimo indicador de contaminação. Estes resultados revelam que a comunidade bacteriana oferece uma boa resolução de locais contaminados usando a citometria de fluxo como metodologia rápida de avaliação complementar à avaliação do estado ecológico sensu DQA sendo, no entanto, necessárias mais estudos aplicados a outras tipologias de rios e outros tipos de impactos para confirmar a validade desta nova metodologia.

La DCE a pour principale ambition d’harmoniser les politiques de l’eau sur un plan européen et d’atteindre le bon état des eaux d’ici 2015. L’évaluation de ce “bon état” implique en outre de dresser l’inventaire, dans les masses d’eau, des 33 substances prioritaires listées en annexe X de la DCE (annexe X, décision No 2455/2001/EC) et pour lesquelles des normes de qualité environnementales (NQE) ont été fixées (Directive 2013/39/EU). Parmi ces substances figurent les polychloroalcanes (SCCPs) et les polybromodiphényléthers (PBDEs) appartenant à la catégorie des micropolluants halogénés “émergents”. D’un point de vue analytique, leur détermination dans l’eau constitue actuellement un enjeu majeur, tant sur le plan de l’échantillonnage que de la sensibilité.Dans ce contexte, ce travail de thèse s’est attaché au développement d’une méthode d’analyse des SCCPs dans les eaux par SPME couplée à la GC/ECNI-MS. Les limites de quantification inférieures à 0,2 µg.L-1 et son degré d’automatisation font de cette méthode un outil de choix pour assurer le monitoring des milieux aquatiques tels que requis par la DCE. En complément de l’approche classique, un pilote de calibration en laboratoire pour l’étalonnage d’échantillonneurs passifs a pu être mis en place et validé pour la calibration des MESCO avec les HAPs. La participation à un essai interlaboratoire a permis de tester l’applicabilité des MESCO et des SR pour l’analyse des PBDEs en sortie de station d’épuration. Enfin la mise en application des LDPE, SR et MESCO sur l’étang de Berre a permis d’obtenir des résultats encourageants quant à l’applicabilité de ces échantillonneurs passifs pour l’analyse des SCCPs et PBDEsIn order to achieve good water quality for 2015, the water framework directives (WFD 2000/60/EC and 2013/39/EU) force European countries to monitor the quality of their aquatic environment. For this purpose, all water bodies shall be monitored for all the 33 priority substances listed in annex X of WFD (annex X, decision No 2455/2001/EC) and for which environmental quality standards (EQS) were fixed (Directive 2013/39 / EU). Among these substances, we found the short chain chlorinated paraffins (SCCPs) and the polybrominated diphenyl ethers (PBDEs) belonging to the class of emergent halogenated micro-pollutants. From an analytical point of view, the analysis of SCCPs and PBDEs in water is still a major challenge, either in terms of sampling or sensitivity.In respect of WFD, this thesis work has, among other things, aimed to develop a method to analyze SCCPs in water by using SPME coupled with GC/ECNI-MS. The limit of quantification below 0.2 µg.L-1 and its degree of automation makes this method a tool of choice to ensure the monitoring of the aquatic environment as required by the WFD. In addition to the traditional approach, a laboratory system for passive sampler calibration was also developed and validated to calibrate MESCO for PAHs analysis. Moreover, our participation in an inter-laboratory study, has served to test the applicability of MESCO and SR for the analysis of PBDEs in a waste water treatment plant. Finally the deployment of LDPE, SR and MESCO in Berre lagoon has yielded some encouraging results about applicability of these passive samplers to analyze SCCPs and PBDE in water

Full textAbstract:
Water governance worldwide is going through a shift towards more holistic and participatory approaches. In Europe, the EU Water Framework Directive (WFD) adopted in 2000, aims at protecting surface water and groundwater. The WFD emphasizes the importance of stakeholder participation in planning and implementation of the directive, and in order to reach environmental objectives. However, the empirical findings are insufficient regarding how stakeholder participation can lead to improved decisions and implemented plans. In Sweden, a major water quality problem is eutrophication caused to a large extend by diffuse nutrient leakage from agriculture. Therefore, it is important to involve farmers in water management, since their participation can lead the commitment of mitigation measures for reduced nutrient leakage. The overall aim of this study is to contribute the knowledge and understanding of active stakeholder participation in water management, in particular how it can lead to implementation of water quality objectives. The thesis addresses stakeholder participation in eutrophication management in local Swedish catchments, with a particular focus on farmers’ participation in the commitment of mitigation measures. The results are based on case study research, involving four catchment areas in Sweden with severe eutrophication problems. The thesis identified socio-demographic factors, farmers’ knowledge, and the level of existing information and economic support for wetland creation, as factors affecting farmers’ willingness to participate in wetland creation to mitigate nutrient leakage. In the local catchment groups studied, farmers and other local stakeholders participated to discuss potential mitigation activities. In these, farmers emphasized other emitting actors’ responsibility and commitment in local action plans. Where this was realized, social capital within the group increased and led to further collaboration. The thesis also analyzed large-scale wetland programmes at catchment scale, where the organizational and institutional arrangements were central to realize farmers’ participation: inter-municipal agreements entailed sufficient resources, the organization involved the most relevant actors; and leadership resources were important. The thesis argues that organizing water management at a catchment level can be important to cope with challenges related to stake-holder participation for mitigating diffuse nutrient leakage. In particular for dissemination and collection of information, suggesting potential measures for all concerned actors, provide resources needed to realize actions, and to build trust and collaboration. The thesis also emphasized that stakeholder participation has to be underpinned by a genuine meaning, both for the initiators and the participants.QC 20150506

Full textAbstract:
Implementation of EU Water Framework Directive has led to an increased demand for cost-benefit analysis in water management. The directive introduces a good status, which is required on all water bodies by 2027. Excessive phosphorus inflows are one of the main reasons for not meeting the criteria in the Czech Republic. If achieving of the good status is not cost-proportionate, exemption can be applied. Many different methodologies were created across different states, including Czech official methodology by Slavíková et al. (2015). However, this methodology does not deal with uncertainty of measures effectiveness. This thesis describes how to implement the uncertainty into calculations using Bayesian networks. A case study of Stanovice water reservoir demonstrates the approach practically. Results of the Bayesian network show, that selected measures with available data eliminate desired amount of phosphorus in 70% of all cases. This reduction is most likely sufficient, because it holds for the upper estimate of required abatement (60 to 200 kg). Based on comparison of benefits and costs, it seems net benefits are generated by implementing suggested measures. Therefore, policy recommendation is to implement the selected measures.
