从法律视角分析三峡库区水环境的保护

随着三峡库区的形成,三峡库区水环境的质量也引起了公众的注意.三峡库区现行的水环境保护法律存在缺陷,即缺乏一部统领性的法律,缺少专门的流域管理机构及协调机制,公众环保意识淡薄,水资源使用制度存在缺陷和污染治理缺乏市场机制.因此,建议采取如下措施:制定三峡库区水污染防治条例,建立库区水环境管理委员会,鼓励公众参与,完善水资源有偿使用制度和排污收费制度.     

蒙古湖泊水环境保护及管理

通过对蒙古地图集和收集相关资料进行分析统计,了解其湖泊水环境保护及管理措施。蒙古国属于内陆国家,是典型的干旱、半干旱地区,水资源较少,主要的水资源载体如河流、湖泊数量较少,且分布不均。近年来,由于人类活动和气候变化的影响,河流、湖泊面临着水体面积萎缩、断流及水污染、环湖沿河土地荒漠化等环境问题。因此,蒙古政府加大对河湖水资源保护和水污染治理力度,通过制定符合国情的水资源管理政策和水制度,从宏观层面加强对水资源的利用和保护;通过发展先进节水技术和水污染处理技术,改善水资源短缺和水环境恶化等问题。

省域水环境保护政策实施效果评价的指标体系构建与实证研究

本文以湖北省"十二五"环境规划的水环境保护指标为主要依据,采用压力—状态—响应(PSR)模型,从污染排放强度、水质改善效果、水资源利用和污染减排效率三个维度出发,建立湖北省"十二五"水环境保护政策评价指标体系,对政策的实施效果进行量化评估。结果表明:湖北省"十二五"期间水环境保护政策实施效果呈逐年上升趋势,从二级指标来看,政策实施在污染排放强度以及水资源利用和污染减排效率两方面均取得较好的成效,但在水质改善方面效果不明显甚至有所下降。建议湖北省在"十三五"期间以至接下来更长的一段时期内,首先要重点加强省内各局部区域的水环境承载能力评估,并依据评估结果对现有的产业布局进行有效的调整;其次应进一步强化环境监测和管理力度,以减少可能的非法排污。本文构建的指标体系对进一步促进省域水环境保护政策实施效果评价的规范化、合理化不无借鉴意义。     

WATER AND WATER RIGHTS TRANSFERS: A NEW POLICY FOR NEBRASKA1

ABSTRACT: Nebraska has abundant supplies of high quality surface and ground water. The U.S. Supreme Court decision in 1982, declaring ground water to be an article of commerce, is widely perceived as giving neighboring states easier access to Nebraska water. Some neighboring states, particularly Colorado and Wyoming, are in water short situations. Additionally, current legal restrictions on certain types of transfers within the State could be inhibiting the “highest and best use” of Nebraska's water. Thus, in 1987 the Nebraska Legislature called for the development of a new water policy for Nebraska that would promote the economically efficient use of water, yet protect the environment as well as the rights of individuals (for example, third parties) and the public. Through an interagency study employing an extensive public involvement process, a policy to be recommended to the Legislature in 1989 emerged. The policy revises the basic definition of water rights and transfers and eliminates most of the inconsistencies in the water allocation system by treating most types of water resources, most types of water users, and most locations of use similarly in the permitting process. (The principal exception is the individual irrigator using ground water on the overlying land where overlying land is one government surveyed section; such use is not defined to be a transfer nor is a permit required.) An impact assessment would be required of most new water uses except on site uses of ground water. Compensation measures could be specified as a condition of the permit where appropriate. The permit would be issued only if the benefits of the proposed transfer clearly outweigh adverse effects that could not be avoided or effectively compensated. The policy allows for the sale or lease of “salvaged” water. It calls for the State to facilitate transfers by acting as a clearinghouse for potential buyers and sellers, and it allows the State to sponsor water projects. An annual fee to be paid by many water users, in order to provide a fund for compensation and for state sponsored water projects, was proposed. However, it met with extensive opposition. Thus, the policy recommends only that the Legislature examine potential funding programs and equitable user fees.     

LAND USE FUNCTION IN WATER QUALITY MANAGEMENT1

ABSTRACT. The Nation has entered a new era of water quality management in which land use policy and regulation must assume an increasingly important role. The benefits of tertiary and advanced waste treatment may be offset by contradictory land use and pollution from land runoff. Unless land use planning and controls are included in water quality management, land-imposed constraints on water quality can be anticipated. Pollution from major types of land runoff are reviewed with respect to sources, effects, and control procedures. Emphasis is given to land use practices and controls. The crucial issue with regard to the latter is lack of land use policies at federal, state, and local levels. State legislation establishing guidelines and minimum standards for land use regulation by local government is required. The dependency of water quality on land use points to the fallacy of attempting to provide for comprehensive water pollution control outside the context of comprehensive land-water resource planning and management.     

SOCIAL FEASIBILITY AS AN ALTERNATIVE APPROACH TO WATER RESOURCE PLANNING1

ABSTRACT: Research suggests that conflict over public participation in water resource planning is due, in part, to confusion over the nature of the policies involved. This article examines the roadblocks to citizen involvement in water resource planning in terms of two policy models: (1) the Social Feasibility Model and (2) the Political Feasibility Model. Each model posits a different role for public participation. Although the Political Feasibility Model has been widely accepted in water resource planning, changes in the nature of the policies involved in water resource management have weakened its appropriateness. Currently, social and redistributive policies involving value conflicts often dominate water planning and these policies are best chosen through the Social Feasibility Model. The article discusses the nature of the social feasibility model, the new types of policy decisions facing water resource managers, and how the social feasibility model can help overcome the roadblocks to increased public participation in water resource policy making.     

THE NATIONAL WATER COMMISSION REVISITED1

ABSTRACT: In 1973 the National Water Commission concluded its five-year study of national water policy by issuing a massive report containing over 200 recommendations for improvements in the way the Nation deals with its water resources. The Carter Administration is now engaged in another water policy review which incorporates many of the policies espoused by the National Water Commission. In this paper, presented at the 13th American Water Resources Conference in Tucson in November of 1977, the author describes the work of the National Water Commission and the actions taken on its recommendations.

DINOSAUR NATIONAL MONUMENT: THE EVOLUTION OF A FEDERAL RESERVED WATER RIGHT1

ABSTRACT: Dinosaur National Monument, in northwestern Colorado, has become a test case in the establishment of a federal reserved water right to instream flows. For the first time, the Interior Department was forced to rigorously defend its claims in a watershed where the federal government did not control the upstream reaches. Inadequate quantification of minimum flow requirements, court orders, and an apparent Congressional ban on the spending of Water Resources Program funds by the Park Service to quantify its water rights have already placed the Service in a difficult position to protect instream flows for maintaining the ecological integrity of the Monument. As late as 1983, administrators of the Park Service were divided over their legal strategy, many wanting to pursue a policy of claiming “natural, historic” flows rather than “minimum” flows. The conditional right to instream flows panted to the Park Service in 1978 was subject to quantification within five years. That deadline has been extended, but it is not likely that the case will reach final settlement this decade. Until the design and conduct of federal water rights quantifications better integrate public policy and law with science, the principle lesson from Dinosaur may have to be repeated.     

AGRICULTURAL NITRATE CONTAMINATION OF GROUND WATER: AN EVALUATION OF ENVIRONMENTAL POLICY1

ABSTRACT: The contribution of agriculture to nitrate pollution of 8Urface and ground water is a growing concern throughout the world. The objective of this article is to evaluate the current environmental policy governing nitrate contamination of ground water in the South Platte alluvial aquifer. In particular, the “best management practice” approach is assessed in its relationship to optimal policy design. First, the current physical environmental problem and existing institutional arrangements are described. Second, legal and economic criteria are brought to bear on the question of appropriate policy design. Finally, the strengths and weaknesses of the existing policy are evaluated in this context and changes in policy that would increase effectiveness are recommended. Considerable justification is found for state-initiated control because victims of ground water pollution are dispersed and risk assessment is technically demanding. However, ex post elements of existing policy must be improved, perhaps through targeting and some devolution in monitoring and enforcement responsibilities.     

AN ECONOMIC OVERVIEW OF HAWAII'S WATER INSTITUTIONS1

ABSTRACT: The problem of allocating scarce water resources among competing uses and users over time in Hawaii is addressed within the context of analytical institutional economics. The nature of this problem has been, in recent years, highly complicated by important institutional changes that control operating decisions for water supply and water pollution. Whereas the imbalance in governmental initiatives regarding changes in the system of water rights (predominantly state) and environmental laws (predominantly federal) are based on U.S. constitutional provisions, the more fundamental roots of the crucial legal doctrines involved have been traced back to the common property concept. This suggests that the more promising opportunities for meeting the water policy challenges of the state are to be found in the historical common property system (ahupua'a) of Hawaii.     

REVISITING STATE WATER RIGHTS LAW1

ABSTRACT: Water resources professionals should be engaged actively in revisiting state water rights law. During the past four years, sponsored by the American Society of Civil Engineers with cooperation of other water resources organizations, over a hundred engineers, hydrologists, geographers, lawyers, administrators, educators, water users, and other persons interested in water law have been preparing a Model State Water Rights Code. Preliminary drafts of the Model Code have been considered in four states, and its provisions will be disseminated nationally to state legislators and other policy makers upon formal publication in September 1994. The Model Code gathers the best provisions from state water laws into comprehensive regulated riparian and prior appropriation provisions, includes commentaries explaining how its textual sections address water resources planning and management issues, and references similar language in current state water statutes. The goal of the Code Project is to provide materials which will assist legislators so they can enact effective, efficient, and equitable water laws. In the future, the Code drafting group will expand its efforts to develop legal guidelines for allocating shared transboundary water resources, water quality law, federal water statutes, and other water resources legal issues.
