The EEC Shellfish Directive is a policy designed to protect and, where necessary, improve the quality of designated shellfish waters. Its implementation within the UK, however, has had no effect upon water quality for two reasons. First, the policy has important defects, having ambiguities concerning public health provisions and lacking designation criteria. Second, UK government has sought to achieve formal compliance, while at the same time ensuring that its full financial impact on public expenditure has been contained. Consequently, only those fisheries which already comply with water quality standards have been designated. Within Wales, one fishery has been designated, while other, commercially more important, but grossly contaminated shellfisheries have not.  相似文献

The current European Directive for the quality of drinking water was originally proposed in 1975 and adopted in 1980. With improved scientific knowledge and a desire to simplify, consolidate and update existing legislation, the commission is currently revising the Directive. Proposed changes include a significant reduction in the value of the lead parameter, which will involve countries such as the UK with considerable expenditure related to the removal of lead pipes and fittings in the water systems. Water quality will in future be measured and expected to comply at the tap. Other proposed changes are also outlined.  相似文献

This paper presents an assessment of the potential impact of the EUs biofuel directive on European land use and biodiversity. In a spatially explicit analysis, it is determined which ecologically valuable land use types are likely to be directly replaced by biofuel crops. In addition, it is determined which land use types may be indirectly replaced by biofuel crops through competition over land between biofuel and food crops. Four scenarios of land use change are analyzed for the period 2000–2030 while for each scenario two policy variants are analyzed respectively with and without implementation of the biofuel directive. The results indicate that the area of semi natural vegetation, forest and High Nature Value farmland directly replaced by biofuel crops is small in all scenarios and differs little between policy variants. The direct effects of the directive on European land use and biodiversity therefore are relatively minor. The indirect effects of the directive on European land use and biodiversity are much larger than its direct effects. The area semi natural vegetation is found to be 3–8% smaller in policy variants with the directive as compared to policy variants without the directive. In contrast, little difference is found between the policy variants with respect to the forest area. The results of this study show that the expected indirect effects of the directive on biodiversity are much greater than its direct effects. This suggests that indirect effects need to be taken explicitly into account in assessing the environmental effects of biofuel crop cultivation and designing sustainable pathways for implementing biofuel policies.  相似文献

The European Union Landfill Directive calls on member states to reduce the amount of biodegradable municipal solid waste disposed of to landfill. In addition, national waste strategies will require the constituent parts of the United Kingdom to achieve increased household waste recycling and recovery rates. Both these measures will require the development of the infrastructure to support national high-intensity recycling and composting schemes and the construction of at least 35 new municipal waste to energy incinerators. Before plans can be developed for meeting the targets several areas relating to municipal solid waste need to be clarified. Depending on the definition of municipal solid waste, its composition and likely future growth rates the number of incinerators required could be up to 170.  相似文献

The Water Framework Directive is the most significant piece of European water legislation to date. This paper looks at the Directive's stakeholder participation requirements, which are crucial to its successful implementation, and represent one of its most novel and potentially far-reaching elements. The Ribble catchment in northwest England is part of a European pilot river basin network tasked by the European Commission with testing the Directive's common implementation strategy guidance, which is designed to aid member states in meeting its requirements. The Ribble pilot, managed by the Environment Agency, is responsible for testing the stakeholder participation element of this guidance. This paper provides an overview of the early stages of the Ribble pilot'sapproach, and discusses stakeholder participation in the context of the Water Framework Directive more broadly.  相似文献
