ABSTRACT Attitudes toward the development of the American West have undergone important changes over the past century just as the nature of water resources as factors in development have changed. Viewing these changes processually, stages for water resources definition and use can be identified in the total process of western cultural development. The first stage involves the value of water resource development as a stimulus to population and economic growth in the West. The second stage, still in process', adopts a dominant cultural norm which sees water resource development as inevitable if not necessary to keep up with growth. A third stage to this evolutionary process is incipient. Future cultural values and thinking with respect to water resource development will be to look at development as a means for controlling or managing both the location and quantity of population and economic growth. To this end planners will have to become concerned with the questions of human adaptation. Concern will have to be given to the problems of getting a living which enables individuals to meet the subsistence needs of self and family, to establishing community which provides for cooperation among individuals and the management of conflict, to establishing improved communication which promotes interpersonal interaction, and for fostering innovation which provides the new ideas necessary to adapt to new environmental situations., 相似文献

Abstract: There are four known geothermal resource areas in the Imperial Valley that have a combined potential of over 4,000 megawatts of electrical energy for 25 years. Water resources available to support geothermal enerfy development are imprted Colorado River water, agricultural waste waters, Salton Sea water, and groundwater. In addtion, geothermal power plants can produce their own cooling water from steam condensate. Nevertheless, the relatively high water requirements of geothermal facilities along with a series of real and potential constraints may cause water supply dilemmas involving both the acquistion and use of cooling water. Important constraints are institutional policies, water supply costs, technical problems, and impacts upon the Salton Sea. These constranits and related dilemmas are examined in light of relevanty information on the valley's water resources, geothermal resources and energy technologies, cooling water requrements, and water supply options. 相似文献

ABSTRACT: Texas is one of the states in which limitations in water supplies could severely constrain economic growth in certain areas. The traditional planning approach for addressing this problem has involved devising schemes for large water development projects, which for many years included the importation of water from other states. Now the attitude towards water resource management is changing, and it is generally agreed that better management of existing supplies is the preferred approach. In this paper we review some of the changes that have recently occurred in Texas, including attempts to streamline the water institutions in such a way that they might be more responsive to the need for more comprehensive management of water resources statewide, with greater emphasis on social and environmental concerns. 相似文献

ABSTRACT: Liquid dominated geothermal systems are expected to account for most of the growth in geothermal energy production in the coming decades. Production of water from such systems could significantly augment fresh water supplies. The feasibility of water exploitation is clouded by potential problems related to seismic impacts, land subsidence and the composition of geothermal brines. If these problems can be overcome at little cost, desalination of brines may be feasible. Estimates of water production costs are presented for a variety of desalination technologies, plant sizes and brine water compositions. These estimates show that production costs will range from $139.10/A.F. to $436.00/A.F. at the plant boundary. Economies of scale and brine composition are important determinants of cost. Production costs are substantially in excess of the value of water in alternative uses. However, in certain unique situations, it may be efficient to desalt brines for use in upgrading the quality of municipal water, industrial process water and irrigation water. Unique situations aside, geothermal brines are not likely to provide an economical source of fresh water in the absence of striking changes in the patterns of supply and demand for water. 相似文献

This article discusses the legal criteria of a mining investment decision - the legal status of investments, fiscal regime and mining legislation. The importance of the security of tenure of mining titles and of the stability of the terms and conditions, as stated from the inception, is emphasized, and the concepts of state sovereignty, state ownership of mineral deposits and state participation in mining ventures are considered. The preference for legalistic solutions rather than ad hoc contracts is stated, and a brief review of the various types of mining agreements is given. Cet article analyse les critères juridiques de la decision concernant l'investissement minier: statut juridique des investissements, régime fiscal et legislation minière. L'importance de la sécurité de la concession minière et la garantie des clauses de contrats est mise en evidence. L'article considère également les concepts de souveraíneté de l'Etat, la propriété étatique des dépôts minéraux et la participation de l'Etat dans la recherche minérale. L'auteur indique sa préférence pour des solutions juridiques plutôt que des contrats particuliers et passe brièvement en revue les différents types d'accords miniers. Este artículo analiza los criterios legates empleados en la toma de decisiones sobre inversión minera: estado legal de la inversión, régimen fiscal y legislación minera. Se da énfasis a la importancia de la seguridad de posesión de los títulos mineros, la estabilidad de las condiciones iniciales de contrato y se consideran también los conceptos de soveranía del estado, propiedad estatal de los depósitos mineros y la participación del estado en la actividad minera. Se indica la preferencia por las soluciones a través de leyes en vez de contratos ad hoc y se revisan brevemente varios tipos de acuerdos mineros. 相似文献

ABSTRACT: The planning and developing of water resources to meet the country's needs for water supply, flood control, hydroelectric power, irrigation, and navigation now needs to take more account of environmental needs and regulations. Water resource development is often beneficial to the environment, but may also be harmful, as in cases involving salmon and various other endangered species. As a national objective, the environment must be preserved and in some cases restored; but how can this be done consistent with other national objectives, relating to life and welfare of human beings? This problem has aroused the concern of many engineers and water scientists. As a result, a national conference on this subject was held in Chicago in June 1998, as an integral part of ASCE's Annual Conference on Water Resources Planning and Management and the Annual Conference on Environmental Engineering. At the conclusion of that conference, a post-conference meeting was held by a group of prominent water resource practitioners. It was concluded at this meeting that action should be taken by our government to establish a new form of interagency approach, involving the states, as a means of coordination in cases of national importance. 相似文献

Decisions to develop water resources systems so far have been primarily taken on the basis of engineering and economic feasibilities. Very rarely, if ever, sociological feasibility has been considered, except in a very broad sense. Planning is for the people, and it should improve the quality of life. Hence, it is argued that water resources decisions ought to be primarily social ones, and that the success or failure of any resource development should not only be judged by its techno-economic excellence but also by its impact on people. Water resources planning process is discussed, and the difficulties associated with the evaluation of sociological feasibility of projects are enumerated. The social consequences of water development projects are traced through planning, construction, operation and management impacts. Finally, it is suggested that the foremost factor in the success of any water management program is the public understanding and acceptance of that program. 相似文献

ABSTRACT: This paper examines the co‐evolution of the Las Vegas, Nevada metropolitan area, Las Vegas Wash ecosystem‐a downstream riparian wetland‐and Wash management as a case of urban‐environment dynamics. Since Las Vegas Wash provides the primary drainage for Las Vegas, changes in the urban system lead to changes in the Wash and its ecosystem. The population of the drainage area has grown from approximately 1,000 people in 1900 to more than 1.3 million in 2000. This phenomenal population growth led to increased Wash flow, from less than .03 m3/sec (1 ft3/sec) to over 7.4 m3/sec (260 ft3/sec), and consequent ecological changes from a nearly dry wash to a rich wetland, and now to an eroded system. As the Wash ecosystem changed, valuation of Wash characteristics by residents and resource managers also changed, shifting the focus of management and use, which ultimately led to further ecosystem changes. Reciprocal relationships among human activity, environmental change, and management in this urban area highlight the need for a comprehensive and dynamic systems perspective and adaptive approaches in urban environmental management and make this a particularly compelling case study. This paper describes a conceptual systems framework for adaptive urban‐environment management derived from this case. 相似文献

ABSTRACT: In this article a managerial approach to developing and implementing National Water Resources policy is suggested. Proper consideration can be given to national economic development (NED), environmental quality (EQ) and conservation and still result in an implementable policy at the operational level if proper incentives are built into the process with proper attention to alternate non-Federal cost sharing rates. Not only can these multiple objectives be entertained but the Administration and Congress will have a management tool that should ensure a certain probability of success. 相似文献

ABSTRACT: Federal planners, in proposing the massive main stem Missouri River water developments in Montana and North Dakota, promised economic and social benefits to the local residents. Five main stem dams, Fort Peck, Garrison, Oahe, Big Bend and Fort Randall, were evaluated for community and rural development effectiveness. Thirty-seven development factors were examined and improvements noted. Only small differences were noted between areas with water developments and the control area. Further analysis revealed that water development benefits moved downstream and to existing urban areas. The Missouri River's rural areas and small communities were not developed significantly by the water projects. Several problems associated with water development policy were illustrated by the study. Cultural differences between planners and the population impacted were ignored. Second, the allocation of social costs was not considered and related to this, serious geographic maldistribution of benefits and costs resulted. The differences between pre-development promises and development performance was dramatic. While the large dams remain as landmarks to engineering prowess, the projects need to be evaluated for their success in meeting humanistic development objectives. Major redevelopment may be warranted by such an ex-post evaluation. 相似文献

ABSTRACT: The traditional strong role of interest groups in water resources policy making has been modified recently by the introduction of many environmental groups. The new groups differ from traditional groups in their relatively modest resources and their relative lack of access to traditional decision points. This paper examines the extent to which the new groups differ in their perceptions of the effectiveness of tactics and in their use of tactics, taking into account group resources and group access to decision makers. 相似文献

ABSTRACT: Ground water is intended to be administered in many western states as a flow or renewable resource. In Idaho, this administration is based on the appropriation doctrine of water rights. Two generalizations may be made concerning ground water. First, water artificially discharged from an aquifer system must deplete the total resource by that amount; water consumptively pumped from a well must be derived from either increased recharge, decreased discharge or a decrease of water in storage. Second, the annual rate of recharge to a ground-water system is often only a small percentage of the total resource in storage. Ground water may be divided into flow and stock portions. In those basins where the second generalization is true, most ground water may be classified as stock. However, only the flow portion of ground water may be developed if utilization of the resource is to be enjoyed over an infinite period. Data from the Raft River Basin in Idaho indicate that the flow and stock characteristics of ground water are time dependent. The resource exhibits the characteristics of both a renewable and nonrenewable resource. As a result, present administrative techniques do not provide for effective management of the resource. 相似文献

ABSTRACT: This paper provides a critical analysis of the Bureau of Reclamation's Auburn-Folsom South project in California. While this massive $1.5 billion project is temporarily halted for redesign for earthquake hazard, it is timely to examine its justification on economic grounds. The key finding is that several major benefit categories, irrigation and recreation, have been grossly overstated. In addition, the Bureau failed entirely to estimate the cost of use on the free-flowing American River, or a probability-weighted estimate of catastrophic loss. Revised estimates indicate that the project is not economically justified. In addition, the project has unattractive distributive effects. The implications of this case study for current revisions in U.S. water policy are explored. The Auburn study basically provides support for the U.S. Water Resource Council's draft manual of procedures for evaluating federal water resource projects. 相似文献

ABSTRACT: Statutory and case law at the state level provide critical legal frameworks for water management. As many state governments struggle to improve efficiency in water management and resolve conflicts over water usage, they must continually assess the efficacy of their state water law. Most states have water laws that are disconnected and overlapping. This article presents a methodology to assess state water law and take first steps toward a comprehensive state water resources act. The methodology is driven by issues and conflicts in water management. It synthesizes management and legal analyses into a process that incorporates the diverse perspectives of state water stakeholders. The results of the analysis are identification of management issues, profiles of state water law, and explorations of legal options that are available to the state government. Illinois is provided as a case study for this methodology. 相似文献

It is presumed that the present environmental thrust is not a wholly transitory fad; that there will be a residual impact on American society which will demand greater consideration in the future of ecological and environmental values by resource developers and public works agencies. An example is cited to show the validity of the environmental thrust and the severe consequences of ignoring it under the present emphasis on this aspect of resource development. An attempt is made to understand some of the reasons for the dramatic change in public attitude toward the environment and opposition to projects of apparent benefit to society. It is suggested that basic changes in philosophy and concept will be necessary in the field of resource development. Some broad ecological and developmental guidelines are provided in the interest of implementing environmental considerations. Finally, those involved in resource development and public works are challenged to accept the concept of eco-engineering; a concept combining the competing elements of resource development and conservation. 相似文献

ABSTRACT: At a time in history when water resource development in the United States is being condemned as both economically inefficient and an environmental disaster, perhaps economists need to look back at previous development to see what the fruits of water development (be they sweet or sour) have been. The Boise Project of south-western Idaho is 70 years old and to some people it represents a gross error in resource use, while to others it represents a means of livelihood and well being. A recent research project at the University of Idaho attempted to measure not only the direct economic income benefits of the project (from irrigation), but also the indirect or secondary income benefits (from the food processing industry). Periodic regional input-output tables were constructed to assess the income generated from irrigation and food processing over the period from 1946 to 1970. Input-output analysis allowed researchers to evaluate the direct and indirect impacts of both the irrigation sector and the food processing sector and to compare their growth over time. 相似文献

ABSTRACT: Changes in watershed management and policy in Hawaii are an instructive case study on the evolution of resource management from a traditional vertically integrated system, to a segmented central government‐based system, and now towards a community and watershed focus. The rise of European social and economic influences coupled with the precipitous decline in the Hawaiian population in the years following European contact led to the destruction of traditional management structures. Subsequently, the dominance of outside interests in Hawaii society and politics, culminating with the sugar industry, facilitated the unrestricted use and privatization of land and water resources. The post‐World War II era ushered in fundamental changes in Hawaii society and politics including renewed appreciation of traditional management practices. Government policies, increased community interest in resource management, and a renaissance in Hawaiian culture have converged in recent years to facilitate the development of new management structures that draw on both traditional and contemporary management. These structures hold great promise for improving Hawaiian watershed management. Our observations suggest that other jurisdictions may find it productive to examine traditional management and policy structures and try to relate them to contemporary community‐based resource management policies and activities. 相似文献

ABSTRACT. In the arid and semi-arid regions of the Western United States the water problem is generally perceived as one of “inadequate” supply. This conception of the problem engenders supply-oriented water policy, or policy focusing exclusively upon a single class of solutions–the various schemes for augmenting an area's water supply. In a more complete or balanced conceptualization, the water problem is viewed as one of “inadequate” supply and/or “excessive” demand. When the water problem is so conceived, water policy is broadened to include demand-oriented water policy, or policy aimed at reducing the quantity of water demanded in an area. The purpose of this paper is to describe and explain demand-oriented water policy. Basically it consists of changing the set of commodities produced by the economy, cutting back and/or eliminating goods requiring large quantities of water in their production and introducing and/or expanding goods which require little water. This paper also reports briefly on research undertaken to test demand-oriented policy in Arizona. Results indicate that such a policy can be extremely efficacious in solving a region's water problem. 相似文献

ABSTRACT: Effectively teaching water resources policy to university science and engineering students is both important and difficult. Most careers in the water resources field require an understanding of the comprehensive governmental regulatory structure affecting water use. Also, few science and engineering curricula encourage their students to take policy courses. Successful approaches to teaching water resources policy might include epistemological comparisons, case studies, issue maps, and interactive simulations. Obstacles to the effective teaching of this subject include students' insufficient preparation and student disdain and cynicism. These obstacles may be mitigated by requiring a prerequisite, developing a glossary of policy-related terms, and introducing the course through lectures emphasizing realistic views of the water resources management field and the nature of the American political system. 相似文献
