Item Open Access Adaptation to climate change: legal challenges for protected areas(Igitur, Utrecht Publishing and Archiving Services, 2009-07-01T00:00:00Z) Cliquet, A.; Backes, C.; Harris, Jim A.; Howsam, PeterClimate change will cause further loss of biodiversity. As negative effects are already taking place, adaptive measures are required to protect biodiversity from the effects of climate change. The EU policy on climate change and biodiversity aims at improving a coherent ecological network in order to have more resilient ecosystems and to provide for connectivity outside core areas. The existing legal framework, the Birds and Habitats Directives, can enable adaptive approaches, by establishing and managing the Natura 2000 network and providing for connectivity measures. However, policy and law so far have mainly been aimed at conserving the status quo of habitats and species within core areas. The question is whether a legal requirement to protect certain species in certain places makes sense when species and even ecosystems are migrating due to climate change. Instead, efforts must be increased to protect ecosystem functions, goods and services from the negative effects of climate change, and to facilitate the ecological restoration of new areas. Even more effort is needed for the implementation of connectivity. If existing legislation proves too weak to face these challenges, a new ‘Ecosystem Framework Directive’ might provide the necessary legal impeItem Open Access Development of a Bayesian network based hybrid-decision support process for potable water management in the context of the water framework directive(Cranfield University, 2012-09) Jackson, Kate; Howsam, Peter; Parsons, David; Jeffrey, PaulUncertain 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.Item Open Access Diffuse pesticide pollution of drinking water sources: impact of legislation and UK responses(IWA Publishing, 2012-06-12T00:00:00Z) Dolan, Tom; Howsam, Peter; Parsons, David J.Diffuse pesticide pollution is a problem for the environment, but it also presents a challenge for water compa- nies managing treatment infrastructure to produce potable water. The legal framework for this context has three main components: that dealing with pesticides and pesticide use, that dealing with environmental water quality and that dealing with drinking water quality. The study set out to identify, interpret and assess the impact of the legal framework related to this challenge. The study found that the current policy and legislation do not provide a coordinated legal framework and some changes are warranted. For example the Water Framework Directive (WFD) sets environmental quality standards for some, but not all, pesticides. Article 7 provides special protection of water bodies used as sources for drinking water supply, but it is not clear whether the UK will achieve full compliance by 2015. This is a problem for water companies planning investment, because the WFD and Drinking Water Directive remain legally distinct. Further uncertainty arises from the application of Regulation (EC) 1107/2009 and the extent that restricted availability of pesticides will drive changes in agricultural practice and pesticide use.Item Open Access Domestic Water Metering - Is the law adequate?(Lawtext Publishing, 2006-01-01T00:00:00Z) Robson, Anne; Howsam, PeterMost domestic properties in England and Wales currently have their water and wastewater charges billed in one of two ways - either as an unmetered charge, based on the property, usually its former rateable value; or as a metered (volumetric) charge, based on a water meter reading. As a general rule, whether an unmetered or metered charging basis would result in a lower bill for a specific customer depends on how much they currently pay, the number of occupiers, and how much water is used.Item Open Access Identifying adaptation options and constraints: the role of agronomist knowledge in catchment management strategy(Springer Science Business Media, 2014-01-31T00:00:00Z) Dolan, Tom; Howsam, Peter; Parsons, David J.; Whelan, M.J.; Varga, LizWater suppliers in parts of Europe currently face occasional Drinking Water Directive compliance challenges for a number of pesticide active substances including metal- dehyde, clopyralid and propyzamide. Water Framework Directive (WFD) Article 7 promotes a prevention-led (catchment management) approach to such issues. At the same time, European pesticide legislation is driving reduced active substance availability. In this context, embedding agronomic drivers of pesticide use into catchment management and regulatory decision making processes can help to ensure that water quality problems are addressed at source without imposition of disproportionate cost on either agriculture or potable water suppliers. In this study agronomist knowledge, perception and expectations of current and possible future pesticide use was assessed and the significance of this knowledge to other stakeholders involved with pesticide catchment management was evaluated. This was then used to provide insight into the possible impacts of active substance restrictions and associated adaptation options. For many arable crops, further restrictions on the range of pesticides available may cause increased use of alternatives (with potential for "pollution swapping"). However, in many cases alternatives are not available, too costly or lack a proven track record and other adaptation options may be selected which catchment managers need to be able to anticipate.Item Open Access Impact of European Water Framework Directive Article 7 on Drinking Water Directive compliance for pesticides: challenges of a prevention-led approach(IWA Publishing, 2013-10-17) Dolan, T.; Howsam, Peter; Parsons, David J.Article 7 of the European Water Framework Directive (WFD) promotes a prevention-led approach to European Drinking Water Directive (DWD) compliance for those parameters that derive from anthropogenic influences on raw water quality. However, the efficacy of pollution prevention interventions is currently uncertain and likely to be variable, which makes absolute compliance with the drinking water standard a significant challenge. Member State governments, the WFD competent authority, the DWD competent authority, water suppliers and agriculture are all affected by and have a different perspective on the nature of this challenge. This paper presents a discussion of these perspectives applicable to stakeholders in all European Member States; the analysis is supported with examples from England and Wales. Improved understanding of the challenges faced by each group is needed if these groups are to achieve the shared goals of WFD Article 7 compliance and DWD compliance without a disproportionately negative impact on agricultural productivity. In addition, the European Commission needs to be aware of and address a potential incompatibility between WFD Article 7 and the DWD. With this in mind, targeted recommendations for action are presented for each stakeholder group.Item Open Access The institutional & legal framework for protecting poor communities' access to water supply and sanitation in the Senegal and Volta river basins(Cranfield University, Cranfield University at Silsoe, 2006-10-04T14:08:53Z) Sallah-Phillips, Antoinette; Howsam, PeterWater is life. While access to water supply and sanitation facilities is considered as one of the most basic human needs, it is also today considered as a human right. Lack of access to safe, affordable, close and adequate water supply and sanitation facilities remains one of the leading causes of diseases and deaths in the world. There are many reasons for this unacceptable situation. One key characteristic is the inadequate institutional and legal framework for water supply and sanitation provision in place. The aim of this research is to gain an improved understanding of existing frameworks, to see what and how it makes the links between the local, regional, national and international levels for communities to access improved water supply and sanitation facilities. The hypothesis being that a framework which does not provide these linkages can have a negative impact on water supply and sanitation provision for poor communities. The research focuses on the institutional and legal frameworks relating to the Senegal and Volta river basins, in West Africa and their constituent countries, one of which, Ghana, is the focus of a more detailed analysis. The study identified that insufficient attention has been given to the establishment of an overall institutional and legal framework at all levels, and particularly to the establishment of regulatory and enforcement bodies at the local, regional, national and international levels and their inclusion in the formulation of water supply and sanitation policies at all levels. A model institutional and legal framework has been developed as a benchmark against which existing frameworks can be evaluated. It draws out key features extending from the local to the international level. The research argues that governments have a primary role to play in facilitating the provision of water supply and sanitation facilities to communities, in particular the poor.Item Open Access The legal framework for offshore wind farms: A critical analysis of the consents process(Elsevier Science B.V., Amsterdam., 2010-08-31T00:00:00Z) Gibson, E; Howsam, PeterThe impact of the legal framework for the consents process on the rate of development of offshore wind farms in England, and the achievement of targets for renewable electricity generation have been reviewed. From the literature and consulted stakeholders it was found that the complexity of the current consents process has adversely affected the rate of development and the achievement of renewable energy targets. Future projects will be subject to a different legal framework for consents, under the Planning Act 2008 and the Marine and Coastal Access Bill. From a comparison of process diagrams for the current and future consents processes, it is concluded that the future process should be an improvement. However, uncertainties remain about the detailed procedures and operation of the future consenting authorities. The capacity and capability of key stakeholders to meet their obligations have implications for the time frame for the processes of applying for, and the granting of, consents. Furthermore improved engagement from developers and clarity about the role of local authorities are essential if progress is to be made. The need for a holistic and strategic view of the industry, including associated development of the supply chain and the transmission grid, is also highlighted. (C) 2010 Elsevier Ltd.

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.
