Abstract

The Water Framework Directive (WFD) is potentially the most significant piece of water management legislation to be developed by the European Union (EU) in the last forty years. Whilst water legislation is already regarded by many people as the ‘gold plating’ of EU environmental policy, many of the previous regulations and policies have focussed on specific point and non-point source water quality problems and have stipulated stringent standards to be achieved within specified time limits. In sharp contrast, the WFD aims to establish a planning and management framework for sustainable use of water and the ecological restoration of entire river systems, many of which do not fit neatly within the political or administrative boundaries of the Member States. Public participation in planning and management decisions is a key aspect of the WFD. This paper describes the specific requirements of the WFD for public participation and examines their implementation in the Ribble basin in North West England. The Ribble is part of a EU river basin network designed to test the WFD implementation guidelines issued by the European Commission. Particular challenges associated with engaging stakeholders in WFD implementation are highlighted and recommendations for future practice are offered.  相似文献

Based on extensive interviews, fieldwork and archival research conducted in southern Mexico, this article explores and analyzes contrasting water-security perspectives of diverse stakeholders in flood-prone portions of the transboundary Suchiate River basin. Complexities of transboundary water issues along an international river that is also a border produce power relationships between the Mexican state and inhabitants, plus historical tensions with riparian neighbour Guatemala, and diverse meanings among local stakeholders. The Mexican state conceptualizes water security as a conventional national-security issue, whereas the basin’s rural inhabitants consider it a matter of human security, albeit in diverse ways that provoke internal conflicts.  相似文献

This study applies the concept of integrated water resources management (IWRM) to a river basin in Iran, and in so doing, proposes a framework for implementing IWRM principles. Issues such as stakeholder participation, sustainability in several subdomains, scenario analysis, dispute resolution, climate change and well-designed models have been considered. Through a river basin simulation model (RIBASIM) and sustainability criteria, stakeholders made decisions for improving the level of sustainability in the basin. The result of decision making for the future was tested under climate change impacts, and the outputs showed serious challenges, so a strategy is proposed for overcoming these impact effects.  相似文献

This paper provides data on the changing character of river restoration within one country within a single policy and legislative framework. The information gathered was based on web searches, meetings and questionnaire responses with organizations and individuals working as environmental policy developers, stakeholders and practitioners of catchment management and river restoration. The paper utilizes this information to explore generic issues promoting and constraining a move to integrated catchment scale river restoration. Catchment scale river restoration was defined as ‘any river restoration activity that singly, or in combination, restores natural catchment processes and a naturally functioning ecosystem and brings benefit or environmental services to the whole catchment and not just to the site of restoration’. The river restoration project data compiled showed that the number of projects in Scotland is on a strong upward trajectory, but the number of catchment scale projects is still limited. The data also showed a trend towards a range of underpinning reasons for river restoration. Traditionally the reasons for river restoration in Scotland have been strongly fisheries focussed, with another key driver being biodiversity conservation. Sustainable flood management and climate change adaptation are seen as emerging drivers of river restoration. In terms of the individuals interviewed, most appreciated that river restoration can bring about multiple benefits and should be underpinned by a good understanding of catchment processes. Our overall assertion based on our study is that unless there is a fundamental paradigm shift, a change in the nature and level of funding for river restoration and a single organization is given overall authority to direct river restoration. ‘business as usual’ will continue and the benefits of catchment scale river restoration will be limited.

ABSTRACT

This article assesses the main problems facing the Spanish Tagus River basin, and the management that has caused (or allowed) them. It examines the economic, social, environmental and political-institutional dimensions of Tagus River management in terms of sustainable development. We find that the institutions responsible for designing and implementing water policy in the Tagus basin have been unsuccessful in balancing the three classic dimensions of sustainability, resulting in systematic and recurrent failure to comply with the European Water Framework Directive and the principles of sustainable development.  相似文献

The Use of System Dynamics Simulation in Water Resources Management   总被引:7,自引:3,他引:4  
In this paper we discuss the use of system dynamics as a methodology with which to address dynamically complex problems in water resources management. Problems in regional planning and river basin management, urban water management, flooding and irrigation exhibit important short-term and long-term effects, and are often contentious issues with high potential for conflict. We argue that system dynamics combined with stakeholder involvement provides an appropriate methodology to address these issues effectively. We trace the theoretical and practical evolution of system dynamics in these areas over the past 50 years. From this review of the literature and selected case studies we identify and discuss a number of best practices and common pitfalls in applications of system dynamics simulation.  相似文献

The increasing involvement of fluvial geomorphology in river channel management has highlighted the desirability of being able to predict spatially differentiated river channel adjustment in relation to prevailing drainage basin characteristics. An exploratory analysis, using data derived from geomorphological reconnaissance surveys and maps, was carried out with the aim of characterizing river channel adjustments in four catchments within the Thames basin. As many of the variables are categorical in nature, logistic regression is utilized to generate multivariate equations which relate four styles of adjustment to catchment characteristics describing rock type, gradient, land use and channel management. Using only the variables which are statistically significant provides a goodness of fit of around 50%. Geomorphological interpretations of the characterizations are provided and, in general, indicate the varying balance between areally extensive natural controls and more localized human influences in shaping the individual styles of adjustment. In the studied lowland environment it appears that few channels are capable of recovering their sinuosity after channel management, thus highlighting the importance of conserving currently sinuous channels and the restoration of previously straightened reaches. Low gradient rural channels set on Chalk or clay favour deposition and thus may be targeted for maintenance operations. Erosive enlargement of the cross-section is promoted where channel straightening takes place in zones of high gradient; an option which should be minimized to reduce further management expenditure.  相似文献

A water vulnerability analysis is made of how sensitivity characteristics of the Ganges–Brahmaputra–Meghna (GBM) River basin may affect adaptive capacity. A co-riparian ‘country perspective’ highlights the importance of local level management actions. Results reveal that vulnerabilities in India and Bangladesh stem from hydrological and ecological factors, but are more linked to poverty and underdevelopment in Nepal. Poor political governance and underinvestment in the water sector add to vulnerability in Bangladesh and Nepal. Overall, Bangladesh is the most sensitive country while Nepal has the least capacity to adapt.  相似文献

In December 2008, the draft programmes of measures (PoM) have been published in the EU member states, which list the measures that will be taken to enhance the ecological status of surface and groundwater bodies, and to reach the environmental objectives of the EU‐Water Framework Directive (WFD). We have analysed the German PoM to identify the main pressures and the restoration measures water managers planned to implement in streams and rivers. The objective was to evaluate the PoM and to identify the main, practically relevant knowledge gaps in river management on which applied river research should focus on. In general, the selection of measures in the PoM was reasonable. In accordance with the analysis of pressures and impacts in Germany, the PoM focussed on measures addressing morphological alterations and river continuity, and the results indicated that diffuse source pollution and fine sediment input were additional main pressures in Central European streams and rivers. Although point source pollution was not a main pressure in most rivers, respective point source measures have been selected for many water bodies. Apparently, these were so‐called basic measures that have to be taken due to other EU‐Directives or national laws. Therefore, although in line with the WFD, it seemed doubtful if the point source measures would help to substantially enhance the ecological status. Furthermore, the results indicated that there was a general lack of knowledge on the effect of restoration measures and a specific knowledge gap in how to enhance the ecological state of heavily modified water bodies (HMWB) in the lowland region with a high land‐use pressure, which was reflected by the high share of water bodies for which conceptual measures have been selected (e.g. developing management plans). Based on the analysis of the PoM and a literature review, we identified the following, practically relevant knowledge gaps in river management: (i) the morphodynamics of river reaches where natural channel dynamics have been restored, (ii) the combined effect of measures addressing diffuse nutrient and fine sediment input at different spatial scales (e.g. riparian buffer strips and land‐use changes), (iii) methods to identify suitable and efficient measures and to define environmental objectives for HMWB and (iv) the effect of measures on less well‐studied biological groups like macrophytes and phytoplankton. There is a strong need to summarize recent research results on these issues, to identify the knowledge gaps and research needs in detail, and to make the results of such a comprehensive literature review or meta‐analysis available for the next 6‐year management cycle and second WFD management plans.

利用清流河流域1961-2012年的降水、气温、蒸发和径流量资料,采用数理统计方法系统诊断了不同尺度水文气象要素的历史演变特征。结果表明,近50年,清流河流域夏季气温呈非显著升高趋势,年与其它季节气温呈显著性升高趋势,在2007年之后,年和季节气温均存在下降的态势。年降水量和夏、冬季降水量呈增加趋势,春、秋季节降水量呈非显著性减少趋势。年水面蒸发量和除春季之外的季节水面蒸发量呈减少趋势,在清流河流域蒸发悖论现象突出。径流量的演变趋势与降水的演变特征总体一致,年和季节径流量均呈增加趋势,其中冬季径流量增加趋势显著;年和季节降水径流量之间的相关系数均在0.65以上,降水是径流量变化的主要驱动要素,因此,未来气候变化特别是降水变化对水资源的影响应引起足够的重视。  相似文献

基于VIC模型的滦河流域综合干旱指数的构建与应用   总被引:1,自引:0,他引:1       下载免费PDF全文
干旱频发已成为严重制约社会经济可持续发展的重要因素,但由于干旱形成机理复杂,影响因素众多,目前尚无公认普遍适用的干旱指数,因此寻找并构建适用于研究区的综合干旱指数成为当前研究的热点和重点。本文以滦河流域为研究对象,选取1960-1979年为研究期,通过对降水距平百分数、相对湿润度和由VIC模型的中间变量-土壤含水量计算得到的土壤相对湿度指数进行主成分分析,构建了适用于该流域的综合干旱指数,对研究期的旱情进行了评价,并与标准化降水指数(SPI)、帕默尔指数(PDSI)的评价结果进行比较,验证其适用性。结果表明:基于VIC模型的综合干旱指数能较好地评价滦河流域历史旱情。该研究在提升海河流域干旱监测和评价能力方面具有一定的理论与实用价值,也为其它流域的干旱评价具有参考价值。  相似文献
