Global climate change related to natural and anthropogenic processes has been the topic of concern and interest world wide. Despite ongoing research efforts, the climate predictions cannot be rated any better than speculative or possible scenarios whose probability of occurrence is, at the present stage, impossible to assess. One of the most significant impacts of the greenhouse effect is anticipated to be on water resources, including different elements of the hydrologic cycle, water supply and demand, regional vulnerability, and water quality. Thus, the impact of climate change appears to be an additional component on top of the large number of existing water-related problems.The existence of the greenhouse effect, the increase of greenhouse gas emissions, and the rise of corresponding concentrations are things that are certain. However, their impacts on hydrology and water management are highly uncertain. In the latter area, one needs information on much smaller spatial and temporal scales than those used in climate studies. The objective of the present paper is to analyze the climate change impact on water resources in a system's perspective, to discuss scientific gaps, and challenge scientific issues. The role of different scales and uncertainties, as well as the hydrological view of global circulation models are also discussed. Our preparedness for probable global (climate) change is reviewed in terms of assessment, planning, design and adaptation. 相似文献

Abstract Presently a change of paradigm in the field of planning and operation of water management schemes can be observed. The introduction of the principle of sustainable development by the United Nations and the principle of integrated river basin management postulated by the European Union play a major role in this context. Introduction of these new principles requires development of new planning tools, which in turn require a much better data basis than available hitherto. This paper deals with new data types already partly available now, partly to be expected to be developed in the medium-range future. The present data situation is discussed, along with the obvious deficits of conventional data. New data types will not be limited to point measurements, but rather must comprise information covering large areas with a higher resolution in time and space than presently available. Remote sensing data will play a more important role in the future. Furthermore, digital maps, digital elevation models, etc. are also of growing importance and will be processed, together with remote sensing and other data, within Geographical Information Systems of future generations also exposing the potential for working with multi-temporal imagery. In the paper it is shown that in the future more accurate data will be available, not only in terms of data quality, but also resolution in time and space. It is shown how the new types of hydrometeorological data postulate new types of hydrological models. Here, distributed system models are of growing importance. Furthermore, it is shown how the combination of remote sensing with other information leads to new data types that allow integrated planning of water resources systems. The potential of real time data is highlighted, particularly in the context of real time operation of water resources systems, especially for flood control. The potential of large-scale data schemes in the context of regional and continental water management schemes is discussed. Global atmospheric models coupled to hydrological models are discussed, and their potential to consider long-distance effects of certain phenomena (e.g., El Niño) are mentioned. For sustainable development of water resources, the potential of long-term data prediction scenarios is evaluated, and an example of this principle for planning future water supply systems is presented. The paper ends with a vision of future developments in planning water management schemes on the basis of new data types 相似文献

黄河流域水资源治理模式应从控制向良治转变 总被引:10,自引:1,他引:9
“治理”是国际社会最近十年发展起来的一种新的管理国家公共事务的思想。从旧的控制到良治,是现代治理追求的目标,其内涵包括扩大公民对公共事务的参与,从只有政府的一个制度实施者转变为包括政府、非政府组织、公民、私营部门、媒体、国际组织在内的多个制度实施者,从黑箱操作到信息公开和信息透明。我国传统意义上的流域治理,基本是一个流域开发和兴利除害的工程概念,和现代治理的概念有很大判别。长期以来我国江河流域水资源的分配,主要采取指令配置、自上而下的控制模式、在水资源日益稀缺的今天,这种治理模式存在严重的体制失效,流域管理呼唤新的治理模式。目前关于流域管理体制改革的探讨已经从政策层面推进到制度层面,水权与水市场的探索也已全面展开。但遗憾的是,流域 讨论大多局限于泛泛的统一管理的思路上。统一管理是一种强化集权控制的思想,虽然已经在实践中发挥了重要作用,但也有其自身的局限性,仍然不能完全回避体制失效的问题。本文借鉴现代治理理念,提出黄河流域的良治框架,特别指出流域治理模式转变的关键是水公共部门的转型,水管理体制的改革归根结底是水公共机构职能的转变。 相似文献

To manage water more effectively, a new approach is necessary, incorporating a balanced set of policies and in stitutional reforms. Its core is the adoption of a comprehensive framework for water management that recognizes the interactions among the elements of a river basin's ecosystem and incorporates cross-sectional and environmental considerations in the design of investments and policies. The new approach also calls for water to be treated as an economic good, for decentralized management and delivery stru ctures, greater reliance on pricing, and fuller participation by stakeholders. 相似文献

Abstract Recent reforms in water resources management in the Murray-Darling Basin are discussed from the perspective of water allocation, water rights, irrigation, and the environment, with particular reference to differences between details in the states of Victoria and New South Wales. A similar review of water resources management is made for Vietnam with some further discussion of the new water law of 1998. Contextual differences are discussed and the opportunities for Vietnam to make use of Australian experience are briefly analysed. 相似文献

对水资源管理的几点认识 总被引:2,自引:0,他引:2
进入21世纪,对水资源管理的工作思路要在“实现工程水利向资源水利转变”的基础上实现第二次转变,即“从自然资源向经济资源转变”,将对水资源的认识提高到“战略性经济资源”的地位来认识,对水资源的管理要强调两只手管理,即:看得见的政府的手与看不见的市场之手相结合。在对水资源进行统一规划,管理的基础上,深入研究水市场基础理论,培育水市场主体,发挥价格的杠杆作用,确定水权分配的原则,实现市场对水资源配置的基础作用,对水权分配与流转,借鉴其他资源市场建立的经验,进行两级市场模式探析。 相似文献

Cameroon is blessed with abundant water resources. Rapid population increase, unplanned urbanisation, intensive industrial and socio-economic development have led to poor and unsustainable management of these resources. Integrated Water Resources Management (IWRM) is a promising approach in ensuring sustainable management of Cameroon’s water resources. It entails management of water for various purposes and not for a single purpose which therefore involves different stake holders aiming at achieving sustainable water resources management. This paper seeks to evaluate recent efforts to implement in IWRM in Cameroon by examining the institutional framework for IWRM in Cameroon, conditions for the implementation of IWRM and proposes reforms for improving IWRM in Cameroon. The paper concludes that reforms such as public participation at local council levels, recognition of water as both an economic and a social good, putting IWRM within the larger context of Integrated Natural Resource Management (INRM) and the exploitation of mathematical models within hydrological basins will improve IWRM in Cameroon. 相似文献
