The Water Framework Directive was implemented in December 2000 and has to be transposed into Scottish legislation by 2003. The Directive provides a major opportunity to enhance the water environment of Scotland and to improve its management through the implementation of river-basin management planning with stakeholder and public engagement and the delivery of a programme of environmental-improvement measures to deliver good ecological status. Whilst the Directive provides unparalleled opportunities, there are significant challenges to its successful implementation in Scotland, where a step-change in managing the water environment will be required. This paper explores some of the challenges which include technical aspects, scale and timing issues, and capacity limitations.  相似文献

An outline of both the scientific and management needs facing the future water quality issues of Scotland is discussed. The scientific needs are considered in terms of monitoring to increase the understanding of hydrochemical processes, issues of scaling, and the need for improved modelling under changing environmental processes. In terms of the management needs, the requirements highlighted relate to improving the ecological quality of Scottish rivers and the implementation of integrated river basin management plans.  相似文献

Hydrochemical data from catchment streams at three Environmental Change Network (ECN) upland catchments in north-east Scotland, south-east Scotland and northern England have been subjected to statistical analysis to separate the components due to long-term trend, season and flow. The relative variances due to each are presented for pH, Ca, SO4-S, NO3-N, DOC and Cl. Long-term trends have been identified with increases in concentration for NO3-N and DOC, decreases in SO4-S concentrations, along with short-term seasonal fluctuations. Application of this trend technique has allowed the detection of changes and contributed to an improved understanding of catchment behaviour.  相似文献

ABSTRACT The system of abstraction controls for irrigation in Scotland is one of local control orders where, to limit abstractions from any particular watercourse, the river purification authority must apply for an order from the Secretary of State for Scotland to cover abstractions from that one watercourse and its catchment. This contrasts sharply with the heavily protective system in England and Wales where the National Rivers Authority has statutory powers to license all abstractions. The purpose of this paper is to examine the abstraction control system in Scotland with a view to highlighting its advantages and limitations, and to suggest ways by which the system can be improved or made more effective.  相似文献

A solid understanding of urbanizing China – the world’s largest and most rapidly transforming urban society – calls for improved urban data provision and analysis. This paper therefore looks at major technological, social–cultural, and institutional challenges of understanding urban China with open data, and showcases our attempt at understanding Chinese cities with open urban data. Through our showcases, we hope to demonstrate the usefulness of open urban data in (1) mapping urbanization in China with a finer spatiotemporal scales; (2) reflecting social and environmental dimensions of urbanization; and (3) visualizing urban China at multiple scales.  相似文献

The global trend towards urbanisation explains the growing interest in the study of the modification of the urban climate due to the heat island effect and global warming, and its impact on energy use of buildings. Also urban comfort, health and durability, referring respectively to pedestrian wind/thermal comfort, pollutant dispersion and wind-driven rain are of interest. Urban Physics is a well-established discipline, incorporating relevant branches of physics, environmental chemistry, aerodynamics, meteorology and statistics. Therefore, Urban Physics is well positioned to provide key-contributions to the current urban problems and challenges. The present paper addresses the role of Urban Physics in the study of wind comfort, thermal comfort, energy demand, pollutant dispersion and wind-driven rain. Furthermore, the three major research methods applied in Urban Physics, namely field experiments, wind tunnel experiments and numerical simulations are discussed. Case studies illustrate the current challenges and the relevant contributions of Urban Physics.  相似文献

The paper explores the evolution of approaches to spatial planning within the enlarged European Union (EU) and seeks to assess the extent to which such approaches have converged. The context for the evolution of the discipline is examined before the extent of convergence is assessed on the basis of case studies examining spatial policy in Ireland, Scotland and Wales and the Baltic States of Estonia, Latvia and Lithuania. The assessment reveals a certain ambiguity where a significant degree of convergence in approach and practice can be detected until closer examination raises the question of how far such convergence has gone beyond the level of rhetoric. Evidence from the case studies also suggests that a lacuna between rhetoric and reality appears to be an emerging characteristic of spatial planning throughout the EU. In this context the need for and value of context sensitive local solutions is clear.  相似文献

This paper reviews some of the current water quality issues relating to the surface waters of Scotland and highlights some of the key issues likely to be significant over the next decade. The sustainable management of water quality requires an appreciation of the temporal and spatial assessment of the resource, together with an identification of reference or natural conditions from which to determine change, and the elucidation of the drivers of change. Only through this integrated approach, can appropriate management strategies be developed and prioritised, bearing in mind that impacts may be decoupled from sources in both time and space. This paper highlights recent trends in water quality (from a hydrochemical perspective) with separation into three broad groups: rivers, lochs and estuaries. For rivers, a general reduction in concentration of determinants that are more indicative of urban point sources (phosphorus, ammonium, suspended solids, biochemical oxygen demand etc.) is apparent, while in more agriculturally-dominated areas, an increase in concentration of solutes that are considered more diffuse in origin, (e.g. nitrate) is reported. The increasing contribution to total loads from diffuse pollutants is a priority area for both research and policy. Current scientific challenges are to define the most appropriate spatial context within which regional water quality issues can be monitored and managed. It is likely that future emphasis will be placed on making an initial ecoregion based grouping in conjunction with physically defined catchment, which will be used to quantify site-specific impacts. Such an organisational approach will provide a mechanism that enables a targeted monitoring strategy to be developed. This will allow the establishment of ecologically based targets for water quality, and an improved understanding the biogeochemistry of pollution reversibility and ecosystem recovery. It is also fundamental to the development of tools through which to predict the time scale and magnitude of any recovery, such that environmental benefit can be optimised against realistic socio-economic constraints. The inter-relations between water quality objectives and the development of legislation for water resources management in Europe are discussed.  相似文献

In order to realize the maximum improvement in customer service and operational efficiency from infrastructure improvement, a rational, integrated and structured approach to capital investment planning is required. This involves undertaking an operational review and predictive study based upon a full understanding of the hydraulic behaviour of the water supply and distribution system, and considers wider issues such as consequences of (a) long-term future demands, (b) environmental issues, and (c) external regulatory pressures.
The methodology has been demonstrated in work carried out for East of Scotland Water as part of their 'integrated network management strategy'.  相似文献

Environmental flows allocation is an intrinsic part of Integrated Water Resources Management (IWRM). This paper analyses socio‐political issues and effects of environmental flows integration on water availability under the context of increased agricultural intensification in an effort to tackle food insecurity. Lack of appropriate framework comprising the procedural requirements and strategic directions as well as prevalence of politically motivated ad hoc development programmes are among major challenges identified. Introducing environmental flows to a perceived satisfactory level would result in a significant increase of unmet irrigation water demand, yet, “productivity first” norm overtakes. This is presumed to be due to skewed focus on irrigation expansion and low awareness on the possible consequences. The particular challenges highlighted generally unveil the inherent contradictions in the IWRM concept putting its claim that the set of principles and entire course stand universally accepted as a means to balance socio‐economic and environmental outcomes under question.  相似文献

The article provides a life cycle assessment (LCA) of a 3-bed room semi detached house in Scotland. Detailed LCA of five main construction materials i.e. wood, aluminium, glass, concrete and ceramic tiles have been provided to determine their respective embodied energy and associated environmental impacts. Embodied energy of various construction materials involved has been estimated to be equal to 227.4 GJ. It is found that concrete, timber and ceramic tiles are the three major energy expensive materials involved. It as been calculated that concrete alone consumes 65% of the total embodied energy of the home while its share of environmental impacts is even more crucial.  相似文献

The Paris-based scientific historian Amy Dahan-Dalmedico asks why a knowledge of numbers, algebra and abstract forms should be key to our understanding of the sensible world. As she reveals, mathematics, like the world itself, has shifted and fluctuated over time since its earliest origins in ancient Egypt. Evolving and morphing as a discipline, it has covered a diverse range of practices and theories. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

This paper compares recent experience in the use of the planning system to facilitate the provision of affordable housing in rural areas of Scotland and England. Following an introduction summarising key issues arising from the relevant literature, the paper first sets out the scale of need for rural affordable housing in the two countries and then summarises the differing planning policy frameworks. Scale of delivery is then addressed and an attempt is made to establish the extent to which differences in performance reflect variations in policy, delivery mechanisms or differing housing markets. The hypothesis is advanced that Scotland, although a more rural country, has made less use of planning policy to tackle issues relating to the need for rural social housing. In both countries scale of provision has lagged behind perceived need and a major reason for this would appear to be the tensions in planning policy between environmental and social sustainability objectives, with the scales so far weighted towards the environmental rather than the social imperative.  相似文献
