ABSTRACT Many of the resources generating aesthetic and visual benefits are publically owned and their optimum use and development depends upon public investment. Traditionally, public investment decisions have been couched in economic terms requiring quantitative measurement of benefits and costs. Since many of the benefits these resources provide are not consumed when they are enjoyed, the total contribution of the resource is imperfectly measured in the usual market sense. Thus, if the provision of these public goods is left to the conventional market mechanism, less than socially optimal investment may occur. This study was designed to investigate whether aesthetic preferences related to water projects could be determined, and whether they differ among different groups of people. A Q sort of 44 photographs of a wide variety of water development projects was conducted with two groups, i.e., photographers (aesthetic man) and town assessors (economic man). The resultant analysis identified two significant factors. Factor 1 provided insight into a hypothesis of nature dominant or man dominant scenes. Factor 2 indicated that the respondents had a negative preference for projects which were in varying stages of completion or appeared to be polluted. Preferences were consistent between the two groups tested. The test revealed that people do not necessarily equate only naturalness with aesthetic appeal, but will accept development as aesthetic, provided that it is designed to complement the natural landscape.  相似文献

In recent years, important changes have occurred in water resources research. There have been major shifts in attitudes of Congress, state legislatures and the general public toward water and related resource issues. Future water research and development will have to be environmentally oriented. Emphasis is shifting to research productivity. To justify research expenditures, hard facts must be produced which demonstrate payoff. Technology transfer (getting research results into the hands of users in an understandable and usable form) is gaining prominence. Research projects must be designed for total problem solution and technology transfer must be incorporated as a part of project objectives. Research must be planned and conducted to meet users' needs. Guidelines for modern research design and technology transfer are presented.  相似文献

ABSTRACT: This paper evolved from a concern that water resource administrators and planners do not have a consistent definition of the value of goods and services of outputs from projects and programs. A more flexible approach to planning and evaluation is presented that recognizes the interaction of production and consumption through the use of commodity demand curves. Use of the concept of consumer surplus permits measurement of the differential impacts on producers' and consumers' welfare. Quadratic programming is suggested as a consistent means of quantifying these differential impacts.  相似文献

ABSTRACT: Federal regulations require agencies administering water resource projects to inform and educate citizens so that they will understand and participate effectively in local programs. Government officials and public involvement specialists have proposed positive outcomes which should derive from agency educational efforts. Eleven interdependent educational goals are identified in this study such that achievement of each goal improves the likelihood of achieving others. Evaluations indicate that educational programs are inadequate and goals are not attained fully. The incorporation of mechanisms employed by professional educators is a potential remedy. Educational and social psychology contain an abundance of effective educational devices and methodologies appropriate for use in informal adult educational programs. An individualized educational program is recommended to meet the needs of a heterogeneous adult audience.  相似文献

ABSTRACT: Regional development and industrialization patterns are investigated and related via regression analysis to water resource investments for the island of Puerto Rico. Although results of this study indicate such investments have little immediate or short-term impact, significant relationships and variations in regional responses appear over longer time periods. This is shown by applying a variation of Zellner's method of performing seemingly unrelated regressions jointly. By this method, subsets of parameter coefficients of specific economic variables were restricted across regional equations while unrestricted coefficients were interpreted as explaining systematic regional variations in response to public investment. Regional differences, obtained by using this method, are frequently neglected when simply examining the overall development process. Among the more interesting results in terms of policy implications is the apparent significant relationship, over the period considered, between changes in the distribution of income and the pattern of water resource development.  相似文献

ABSTRACT: Proper planning of water resource management programs is the essential ingredient for effective decision-making. Increasing demands on our finite water resources make it more vital that programs get off the shelf and are acted upon. There is a gap between our intentions for and OUI results from the planning process. We should examine our failures, identify causes, and learn from them. One of the primary causes is failure to identify the potentials of the implementing agencies early in the planning process. These agencies constitute a hierarchy of governmental units at national, state, regional and local levels. Each of these levels has its own interests, point of view, capabilities and constraints. A plan which is technically and functionally sound can fail as a program if these conflicting interests are not accounted for. The implementation mechanisms must be identified as an initial phase of the planning process. All levels of the governmental hierarchy must be involved throughout the planning process. The successful plan must also provide for suitable assignment of responsibilities which are accepted by the executing agency and monitored for satisfactory fulfillment. Consistency and continuity of the advocate agency are further essential elements to the success of the plan. Experience in water resource management planning has shown that these strategies will produce programs which are accepted, implemented and accomplish the goals and objectives of the planning process.  相似文献

Household water use behavior: An integrated model   总被引:1,自引:0,他引:1  
Water authorities are dealing with the challenge of ensuring that there is enough water to meet demand in the face of drought, population growth and predictions of reduced supply due to climate change. In order to develop effective household demand management programs, water managers need to understand the factors that influence household water use. Following an examination and re-analysis of current water consumption behavioral models we propose a new model for understanding household water consumption. We argue that trust plays a role in household water consumption, since people will not save water if they feel others are not minimizing their water use (inter-personal trust). Furthermore, people are less likely to save water if they do not trust the water authority (institutional trust). This paper proposes that to fully understand the factors involved in determining household water use the impact of trust on water consumption needs investigation.  相似文献

ABSTRACT. Water and related land resource planning has generally been characterized by project evaluation in isolation. Feasible alternatives have been ignored because the economic analysis did not include the interdependence of such subregional and regional variables as factor and product prices and production possibilities. This paper presents an economic framework, consistent with a regional development objective and an efficiency criterion, for proposing and evaluating resource projects. Subregional and regional derived demand curves for water are developed under alternative assumptions of subregional competition, regional market restraints, and yield and price uncertainty. The derivation of water demand curves using the proposed regional framework as compared to sub regional isolation has the desirable properties of (1) a marginal analysis that is more flexible over time is substituted for a static average analysis; (2) range estimates incorporating probabilities are substituted for point estimates; (3) approximations to functional demand curves are substituted for “needs”; and (4) fewer resources are required to meet a regional market restraint.  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: Recent Federal and some State legislation has enlarged the scope of permitted or required actions of local units of government in water resources management and protection. Much of the legislation encourages local units of government to introduce water resources planning measures which will be preventive instead of corrective. Extensive public works measures, environmental destruction and the threat to human life can thus be eliminated or reduced. Research has developed and tested a method for identifying the elements of a water resources protection program for small urbanizing watersheds which was technically adequate and socially acceptable to the communities implementing such programs. Research results suggest that deliberate efforts will be necessary to inform and educate local units of government as to the usefulness of the legislation; and that the program must reflect local natural resource conditions and local preferences for the method of accomplishing the protection. Successful implementation could be restrained by inertia of local units of government, a lack of tradition in such programs, and hostile existing agencies.  相似文献

Scholars and water resource professionals recognize citizens must get involved in water resource issues to protect water resources. Yet questions persist on how to motivate community members to get and stay civically involved in nonpoint source pollution issues, given that problems are often ill‐defined. To be successful, interventions intended to engage individuals in collective action must be based on an understanding of the determinants of public‐sphere behavior. The purpose of this study is to explore the psycho‐social factors which influence landowner civic engagement in water resource protection. Data were collected using a self‐administered mail survey of landowners in the Cannon River Watershed and analyzed using structural equation modeling. Study findings suggest landowners are more likely to be civically engaged in water resource issues if they feel a personal obligation to take civic action and perceive they have the ability to protect water resources. Landowners who believe water resource protection is a local responsibility, perceive important others expect them to protect water resources, and believe they have the ability to protect water resources are more likely to feel a sense of obligation to take civic action. A combination of strategies including civic engagement programs addressing barriers to landowner engagement will be most effective for promoting civic engagement in water resource protection.  相似文献

ABSTRACT: This paper illustrates one mode of analysis for estimating the benefits of water pollution control projects. Results indicate regional benefits associated with an abatement program instituted for point source pollution along the Housatonic River during the 1960's were substantial. Studies of this kind can aid regulatory and recreation resource administrators in devising and evaluating environmental programs.  相似文献

ABSTRACT: Demand side management is being used increasingly by Ontario municipalities as a way to improve the efficiency of water use, defer the costs associated with constructing new water treatment works, and minimize the environmental impacts associated with supplying water. A comprehensive survey of 153 Ontario municipalities was completed in mid‐1998. These ranged in size from small rural townships (with populations as low as 500 people) to the province's largest urban center, Metropolitan Toronto, with a population of approximately 2.5 million people. The questionnaire measured the use of six broad types of demand side measures, including water pricing and metering; municipal by‐laws (ordinances) that promote water conservation; operational and maintenance measures to reduce water losses and consumption; water‐saving plumbing fixtures and devices; public participation programs that encourage water conservation; and other measures, such as water audits. Additionally, the survey collected data on implementation barriers and opportunities. Since the last comprehensive Ontario survey, conducted in 1987 by Kreutzwiser and Fea‐gan (1989), there has been an increase in the use of basic tools such as metering and pricing, plumbing fixtures, and public participation programs. Additionally, new initiatives, such as water audits and computerized monitoring equipment, are being used. However, in many areas opportunities exist to make better use of demand side measures. Unfortunately, municipal capacity to do so often is constrained by (among other factors) limited finances, lack of political will, and public resistance. Demonstration of real cost savings to consumers, and the development of specific goals and objectives for demand side management programs, are two important steps needed to overcome these challenges.  相似文献

Public perceptions about water quantity and water as a common pool resource are understudied in humid regions. As water demand increases, the need to more closely manage water, even in humid areas, will increase, requiring better understanding how people perceive their water supply, how they view paying for water conservation and how water user characteristics influence attitudes. A survey finds correlations between utilizing an individual water source (e.g. well or spring) and attitudes toward water management and conservation. Compared to respondents with a shared water source, those with an individual source believe they are segregated from regional water concerns. They are less willing to pay for water management or conservation measures and less supportive of any government intervention in water management. These results suggest that planners and water managers may face resistance to conservation policies or any policy based on the idea of water as a common pool resource.  相似文献

Official statistics and surveys show that woodfuel is the dominant end-use of forest products especially in developing countries. This paper examines the end-use pattern and per capita consumption figures for selected developing countries. In terms of total energy requirements woodfuel, a renewable resource, is the third most important fuel after oil and coal, but may be the primary fuel in terms of number of actual consumers. The future consumption pattern is estimated for the developing and developed countries and it is anticipated that total woodfuel consumption may increase by about 2 per cent per year at least until the year 2000. The supply position shows that while present consumption of all forest products is more or less in balance with the increment of the growing stock, in certain areas the forest capital is being depleted to meet demand. Total demand is likely to double by the turn of the century. Therefore, plantations, especially of fuelwood, will have to be established if the growing stock is not to be depleted and if an energy crisis in developing countries is to be averted.  相似文献

ABSTRACT The growing social consciousness and concern with human well-being has resulted in numerous water resource use and control programs, the results of which must be measured not in the customary monetary terms, but rather in terms of social and human welfare. Interdisciplinary research offers the greatest promise of yielding fruitful results in establishing planning methodology that would result in a maximum utilization of funds available for water resource programs. Working with the various social science disciplines, accountants have begun research in social measurement thus opening the door to a new field of accountancy known as socio-economic accounting. The development of social accounting systems will improve water resource management by projecting heretofore unmeasureable social values into the management decision making process.  相似文献
