THE SOCIAL CONTEXT OF WESTERN WATER DEVELOPMENT1

ABSTRACT: Social scientists were included in the planning and design for an integrated, trans-basin water resource project. Within this complex project, a socioeconomic impact assessment (SIA) concentrated on identifying the social, political, and economic issues and potential impacts inherent in developing a city's water rights. Before the SIA began, some of the development alternatives had already generated widespread hostility and organized opposition from communities within the watershed. The SIA involved residents of affected communities in the study design and project planning. The study found a number of components that constituted the concerns, beliefs, and expectations about perceived, potential impacts that might result from the different alternatives. In most cases these issues constituted threats to valued environmental resources, valued community resources, the social environment, the economic base, and a secure future. The social science component was a key factor in the ultimate decision to pursue a particular alternative which was sensitive to the social and political issues, minimized environmental and socioeconomic impacts, and ultimately had support among the communities potentially affected. The experience from this case study suggests that the approach used can be applied successfully in the planning of other water development projects and result in cooperation from the wide range of interest groups that often present costly obstacles to such projects.     

The significance of environmental impacts: an exploration of the concept

Since environmental impact assessment (EIA) is concerned primarily withsignificant environmental impacts, the concept of impact significance deserves to be defined and applied rigorously. In this article use of the term over the past 15 years in EIA documentation is reviewed. Some recent attempts at elucidating the concept are summarized. Four perspectives on impact significance that emerged from a series of workshops on the ecological basis for EIA are presented. These perspectives include (a) statistical (related to problems of isolating project-induced changes from natural variation), (b) ecological (related to the importance of project-induced changes from a purely ecological perspective), (c) social (related to the acceptability of project-induced changes in important environmental attributes), and (d) project (related to whether project-induced changes will indeed influence project decision making). The following synthesis is proposed: Any exercise in judging the significance of an environmental impact should thoroughly consider (a) the importance of the environmental attribute in question to project decision makers, (2) the distribution of change in time and space, (c) the magnitude of change, and (d) the reliability with which change has been predicted or measured. The implications of considering these factors are discussed.     

EFFECTS OF POTENTIAL WATER CONSERVATION EFFORTS IN EAST TENNESSEE1

ABSTRACT: The importance of water conservation was emphasized by a proposed National Water Policy which was established during the previous Carter Administration. This policy stressed water conservation on a national scale. Such a policy sought to apply one program to all water resources problems. Before implementation of this or another such policy, consideration must be given to those vast areas of the country which in reality do not have a shortage of water. One of these areas is the French-Broad River basin in Tennessee. This report was formulated in an effort to describe both the positive and negative effects of water policies which would bring about either a 10 percent or 30 percent reduction in water usage in this basically water rich area. The parameters used in the evaluation included selected economic, sociological, legal, and environmental impacts.     

Poldering vs compartmentalization: The choice of flood control techniques in Bangladesh

The choice of flood control techniques in Bangladesh is reviewed in the context of a case study on the impact of a small-scale polder, the Dhaka-Narayanganj-Demra (DND) Project. The results of a questionnaire survey among the urban floodplain residents, who have settled inside the polder and a control population from outside the polder, indicate that the project has achieved significant flood alleviation but has also induced considerable environmental degradation due to stagnation of water within the enclosed embankment. The project also experienced numerous problems of structural instability of embankments during major flood events. An attempt is made to extrapolate some of these adverse environmental impacts of the polder to the compartmentalization scheme, which has been proposed by a UNDP-sponsored Flood Policy Study as an innovative technique for floodplain management in Bangladesh. The findings of the study, however, do not provide an adequate basis for assessing viability of the proposed compartmentalization scheme. Nonetheless, the study illustrates the usefulness of questionnaire surveys among floodplain residents for obtaining data for project evaluation.     

USE OF DELPHI METHODOLOGY TO ASSESS GOALS AND SOCIAL IMPACTS OF A WATERSHED PROJECT1

ABSTRACT: The major objective is to report the way the Delphi methodology was employed in an environmental study aimed at identifying and ranking goals and social impacts of Cooper Dam and Reservoir Project located in the East Texas area. The Delphi procedures were modified to accommodate the nature of social field under study. Data were collected through personal interviews from twenty-seven respondents representing the government agency responsible for planning the Project and three communities geographically contiguous to the project. The respondents were provided an initial list of the Project's goals and social impacts and were asked to rank them in terms of degree of importance and to add to the list other goals and impacts that they would consider necessary. Respondents were interviewed in two successive rounds. Data show that on the whole the Delphi procedures were helpful in action analysis of the Project by identifying and ranking its goals and social impacts in terms of selected criteria.     

Results of Community Deliberation About Social Impacts of Ecological Restoration: Comparing Public Input of Self-Selected Versus Actively Engaged Community Members

Participatory processes for obtaining residents' input about community impacts of proposed environmental management actions have long raised concerns about who participates in public involvement efforts and whose interests they represent. This study explored methods of broad-based involvement and the role of deliberation in social impact assessment. Interactive community forums were conducted in 27 communities to solicit public input on proposed alternatives for recovering wild salmon in the Pacific Northwest US. Individuals identified by fellow residents as most active and involved in community affairs ("AE residents") were invited to participate in deliberations about likely social impacts of proposed engineering and ecological actions such as dam removal. Judgments of these AE participants about community impacts were compared with the judgments of residents motivated to attend a forum out of personal interest, who were designated as self-selected ("SS") participants. While the magnitude of impacts rated by SS participants across all communities differed significantly from AE participants' ratings, in-depth analysis of results from two community case studies found that both AE and SS participants identified a large and diverse set of unique impacts, as well as many of the same kinds of impacts. Thus, inclusion of both kinds of residents resulted in a greater range of impacts for consideration in the environmental impact study. The case study results also found that the extent to which similar kinds of impacts are specified by AE and SS group members can differ by type of community. Study results caution against simplistic conclusions drawn from this approach to community-wide public participation. Nonetheless, the results affirm that deliberative methods for community-based impact assessment involving both AE and SS residents can provide a more complete picture of perceived impacts of proposed restoration activities.     

Health is wealth: Concern for households’ solid waste self‐disposal practices

This study examines the challenges posed by solid waste by assessing the disposal methods practiced by residents in the Ijebu‐Ode Local Government Area (LGA) in Ogun State, Nigeria. Primary data were obtained through questionnaire administration. One out of every 10 houses was selected for sampling in six randomly selected wards of Ijebu‐Ode LGA. Three hundred and twelve questionnaires were administered on heads of households. Information elicited from the respondents covered solid waste disposal practices, the rationales behind those practices, and the respondents’ perceptions of environmental problems, including environmental health problems that could emanate from such practices. Data on environmental problems and environmental health problems measured on a 5‐point Likert scale were analyzed using Aggregate Weighted Mean Index. The computed Environmental Problem Indices (EPIs) and Environmental Health Problem Indices (EHPIs) were used to determine the severity of the respective challenges. The results established that blockage of drains with an EPI of 4.15 was a very severe environmental problem and flood hazard with an EPI of 3.55 was a severe environmental problem resulting from solid waste disposal practices. Incidence of malaria and cholera, with EHPIs of 2.85 and 2.56, respectively, were however ranked as not severe environmental health problems. The study concluded that solid waste disposal practices in Ijebu‐Ode LGA were unhygienic and unsafe, hence the need for government intervention to ensure the adoption of the necessary measures toward a safe and healthy environment.     

ECOSYSTEM MODELING OF A FORESTED RIVER BASIN1

ABSTRACT: A present concern in decision making processes for forest land use is the environmental effects of land use activities on water, air, and the land itself. Criteria for evaluating the magnitude and detriment of environmental impacts are not definite since it is often difficult to isolate a particular activity as the cause of a particular impact. Instead, interactions between various forest practices must be considered along with their integrated impacts. In order to provide an effective decision tool, the College of Forest Resources, University of Washington, is modeling the forest ecosystem of the Snohomish River Basin located in the Cascade Mountains of western Washington. The project consists of a general system model comprised of subsystem models dealing with product conversion processes, forest production processes, recreation supply processes, wildlife and fisheries supply processes, and the interactions of these processes with water and the atmosphere. The system model is interfaced with a computerized multiple player management game which enables land managers, manufacturing managers, and regulation agency personnel to make management decisions and respond to indications of lack of environmental control. Responses of the hydrologic system to various management decisions are simulated by the water subsystem model. The responses being considered include surface flow quantity and water quality. The model emphasizes the monitoring of non-point as well as point source impacts rather than predicting short-term hydrographs. The significance of impacts vary with land use patterns and the goals of the game player. Therefore, the model has flexible resolution and is able to predict hydrologic conditions for both large and small scale. The water subsystem model responds to management decisions by interpreting the effects of management options selected by game players for 40-acre cells within the Basin. The model then determines which streams are immediately affected, defines the watersheds contributing to these streams, and extracts from a resource data bank the information needed to define model parameters. Using these parameters and precipitation inputs, mean flow discharge on a montly and annual basis is calculated for the impactcd sub watersheds as well as 21 major watersheds of the Basin. Water quality responses predicted for these watersheds include suspended sediment concentration, temperature increases due to stream exposure, dissolved oxygen concentrations, the effects of fertilization on nitrogen content, biocide and herbicide effects, and residues from product conversion processes.     

Assessment of risk to aquatic biota from elevated salinity -- a case study from the Hunter River, Australia

A linear engineering project--i.e. a pipeline--has a potential long- and short-term impact on the environment and on the inhabitants therein. We must find better, less expensive, and less time-consuming ways to obtain information on the environment and on any modifications resulting from anthropic activity. We need scientifically sound, rapid and affordable assessment and monitoring methods. Construction companies, industries and the regulating government organisms lack the resources needed to conduct long-term basic studies of the environment. Thus there is a need to make the necessary adjustments and improvements in the environmental data considered useful for this development project. More effective and less costly methods are generally needed. We characterized the landscape of the study area, situated in the center and north-east of Argentina. Little is known of the ecology of this region and substantial research is required in order to develop sustainable uses and, at the same time, to develop methods for reducing impacts, both primary and secondary, resulting from anthropic activity in this area. Furthermore, we made an assessment of the environmental impact of the planned linear project, applying an ad hoc impact index, and we analyzed the different alternatives for a corridor, each one of these involving different sections of the territory. Among the alternative corridors considered, this study locates the most suitable ones in accordance with a selection criterion based on different environmental and conservation aspects. We selected the corridor that we considered to be the most compatible--i.e. with the least potential environmental impact--for the possible construction and operation of the linear project. This information, along with suitable measures for mitigating possible impacts, should be the basis of an environmental management plan for the design process and location of the project. We pointed out the objectivity and efficiency of this methodological approach, along with the possibility of integrating the information in order to allow for the application thereof in this type of study.     

INTERDISCIPLINARY ENVIRONMENTAL ANALYSIS FOR TIMBER SALE PLANNING1

ABSTRACT: A method of project planning for systematically assessing and recording impacts of alternative timber harvest startegies for subareas of a sale planning area is presented. This method uses an interdisciplinary team composed of specialists and decisionmaker to develop and analyze treatment alternatives and uses impact prediction matrices with explicit evaluation criteria to illustrate and record ratings of impacts on resource factors. The method is a system for organizing, for discovering appropriate alternatives, for facilitating interaction, and for documenting environmental analysis. It provides for decisionmaker control over the project, for exchange of value perspectives, and for reduction in conflict between specialists. The quality of decisions which result from the method presented depends upon the information available and the effectiveness of interaction between all members of the interdisciplinary team.     

AN ASSESSMENT OF USES MADE OF A MULTIPURPOSE RESERVOIR'

ABSTRACT: Data were collected from residents of a rural community at two time periods to assess attitudes toward uses made of a reservoir which had been recently constructed in the area. The findings revealed that attitudes became significantly more favorable for flood control, water supply, and recreation uses of the reservoir. Attitudes toward fish and wildlife conservation use were not significantly different over time but these uses were perceived positively at both time periods. The data were also analyzed in the context of a vested interest perspective using cross-sectional design. The findings demonstrated that the theoretical model used to guide the investigation was quite useful in predicting attitudes toward the four uses examined.     

The Impotence of Cumulative Effects Assessment in Canada: Ailments and Ideas for Redeployment

Cumulative effects assessment (CEA) in Canada is in dire straits. Despite a huge amount of talk and a flurry of developmental activity associated with CEA concepts, it has not lived up to its glowing promise of helping to achieve sustainability of diverse valued ecosystem components. This article aims to articulate that failure, to examine it in terms of six major problems with CEA, and to propose solutions. The six problem areas include (1) application of CEA in project-level environmental impact assessments (EIAs), (2) an EIA focus on project approval instead of environmental sustainability, (3) a general lack of understanding of ecologic impact thresholds, (4) separation of cumulative effects from project-specific impacts, (5) weak interpretations of cumulative effects by practitioners and analysts, and (6) inappropriate handling of potential future developments. We advocate improvements not only within the purview of project-specific EIAs, but also mainly in the domain of region-scale CEAs and regional environmental effects frameworks (or perhaps land use planning). Only then will the CEA begin to approach the promise of securing sustainability of valued ecosystem components.     

STREAM IMPROVEMENTS AND FISH RESPONSE: A BIO-ENGINEERING ASSESSMENT1

ABSTRACT: Human modifications of natural streams in the name of habitat improvement take various forms, and the impacts of those improvements, both positive and negative, vary by orders of magnitude from stream to stream. The positive impacts are achieved through careful and timely planning, design, installation and monitoring of projects. Negative impacts are the results of rush jobs dictated by available money, a lack of consideration for limiting factors, untrained and inexperienced personnel, force-fitting structures instead of bending the flow, lack of a watershed plan, poor communication and cooperation among disciplines, not using the team approach, and single habitat solutions which neglect diversity and artificial constraints. These problems are discussed from various perspectives, but emphasis on an integrated, bioengineering approach is threaded throughout the discussion of the problems and benefits associated with stream improvements and fish response. A general systems approach is presented which uses common language as a focal point for interdisciplinary communication, which is one of the major problems in resource management. Various conceptual models are discussed to describe system complexities, and factors which constrain project evaluation in terms of biological, physical, economic and other components. Conclusions about why some projects are successful, while others are not, are followed by recommendations for concerted and diversified efforts to improve our success in stream stewardship.     

Made in conflict. Local residents' construction of a local environmental problem

The aim of this paper is to understand how local residents participate in the construction of local environmental problems and to evaluate a particular analytical approach in environmental sociology to study this phenomenon. The paper is based on an interview study with a sample of local residents. The analysis demonstrates how the local residents attempt to construct a local environmental problem. In particular, the study focuses on how involved actors are positioned, how different sorts of knowledge claims are used, and how the neglect the residents perceive from the authorities affects the attempt to construct a local environmental problem. The study shows that the local residents play a central role in the construction of the situation and that the evaluated model could be very helpful as an analytical tool in the investigation of local residents' participation in the construction of environmental problems.     

Environmental justice in Appalachia Ohio? An expanded consideration of privilege and the role it plays in defending the contaminated status quo in a white,working-class community

Environmental justice addresses inequitable distributions of health risks from exposure to pollution and other hazards. Appalachian residents of southeastern Ohio who live along the Ohio River are disproportionately subject to industrial pollution. Of particular concern is the DuPont Washington Works plant where perfluorooctanoic acid, or C8, was used to make consumer products. Although company officials became aware in 1984 that the water supply of Little Hocking, Ohio, was tainted with C8 coming from its plant, residents were not notified until 2002. Subsequent studies determined a number of health problems, including cancer, are linked to residents’ exposure. This qualitative study asked Little Hocking residents and environmental regulators if they consider C8 contamination in Little Hocking an injustice. Results indicate a lack of consensus – even among affected residents – concerning DuPont's^® actions as constituting an injustice. This finding, among others, is used to argue that many residents in Little Hocking, through their association with DuPont^®, benefit from class-based forms of privilege and seek to maintain them in the context of immobility and economic uncertainty. This explains why some communities may be considered an environmental justice community from an academic standpoint, but not self-identify as such. However, maintaining privilege at the local scale in the context of weak regulation enhances exploitation in Little Hocking while contributing to power at extra-local scales. Thus, environmental justice activists in white, working-class communities must overcome the challenge posed by privilege that defends the contaminated status quo.     

The limitations of environmental management systems in Australian agriculture

The efficacy of government-supported programs to encourage improved management of land and water systems associated with agricultural land in Australia has been mixed. The broad approach of Australian governments is reviewed briefly. Evidence is presented from case assessments of a program to promote adoption of environmental management systems (EMSs) to improve environmental outcomes from agricultural practices. EMSs are systems implemented to manage the environmental impacts and ameliorate environmental risk associated with business activity. Data are presented on reported EMS activity and experience of four selected groups of farmers in Victoria, south-eastern Australia, representing broad-acre cropping, beef and dairy farming. The pro-environmental behaviours of farmers were mediated through voluntary adoption of government and industry sponsored EMSs, often with financial incentives and other support. Findings from the study were that adoption of EMS practices with sufficient public benefits is unlikely to occur at sufficient scale for significant environmental impact. Farmers more readily adopted practices which were financially beneficial than those which had a positive environmental impact. Although the focus on voluntary market-based instrument (MBI) type programs is popular in western countries, enforcing regulation is an important, but usually politically unpopular, component of land use policy. The comparative advantage of EMSs differed for the industries studied, but overall there were insufficient market drivers for widespread EMS adoption in Australia. Environmental outcomes could be more effectively achieved by directly funding land management practices which have highest public net benefits. Having a clear and unambiguous management objective for a particular land management policy is more likely to achieve outcomes than having multiple objectives as occurs in a number of international programs currently.     

禾木景区社区居民旅游影响感知实证研究

旅游目的地居民作为旅游产业的重要利益相关者,对当地发展旅游业的感知和态度直接影响着当地旅游资源的合理利用及旅游业的健康发展.运用社会交互理论和道科西旅游发展阶段理论,通过问卷调查和实地访谈的方法,从四个维度研究了禾木景区社区居民对旅游影响的感知和态度.结果表明,当地居民对旅游经济的影响大都持乐观的支持态度,旅游发展使居民的生计方式、收入水平明显改善;对生活环境的影响较大,对生态环境和环保意识的影响较小;对居民的传统文化影响较弱,居民与游客的双向交流很少,旅游业仍处于初级发展阶段.因此,当地居民的旅游感知目前还停留在经济层面,缺少对传统文化、自然生态、环境保护等感知的关注.     

POLITICAL ECONOMICS OF OFFSHORE OIL

The exploration of offshore areas for hydrocarbons has involved new technical and economic considerations and has posed new problems, not the least of which has been the changing relationship between companies and governments. In this article, the authors present an analysis of the different perspectives and policies which emanate from national governments on the one hand and from transnational oil companies on the other. The issues examined include the considerations involved in establishing exploration legislation, post-discovery problems, the impact on revenues of increased production, the interests of companies in developing fields and the overall economic environment within which decisions have to be agreed.     

THE PSYCHO-SPATIAL DIMENSION OF GLOBAL ENVIRONMENTAL PROBLEMS

There has been little research on the differential aspects of the local/global dichotomy, yet there is every suggestion that such a distinction could be crucially important in terms of understanding the public's perceptions and attitudes towards environmental problems as well as understanding their subsequent behaviour. This research sought to address three questions. First, are people only able to relate to environmental issues if they are concrete, immediate and local? Second, do people consider environmental problems to be more serious at a global or a local level? Third, what is the effect of the public's perceptions of the seriousness of environmental problems on their sense of responsibility for taking action?Three studies were undertaken in Australia, England, Ireland and Slovakia. The results of each study consistently demonstrate that respondents are not only able to conceptualize problems at a global level, but an inverse distance effect is found such that environmental problems are perceived to be more serious the farther away they are from the perceiver. An inverse relationship was also found between a sense of responsibility for environmental problems and spatial scale resulting in feelings of powerlessness at a global level. The paper concludes with a discussion of various psychological theories and perspectives which informs our analysis and understanding of what might be seen as environmental hyperopia.
