Environmental impact assessment for Xiaolangdi Yellow River multi-purpose economic-cumenvironmental improvement project

Summary The Yellow River is renowned for its life-endangering floods, a problem augmented by the continuous heavy siltation of its lower flood plain. Major dam and reservoir projects have both positive and negative environmental impacts, and their construction requires careful environmental consideration. This paper outlines the key findings of environmental impact assessment reports related to the Xiaolangdi Yellow River dam/reservoir project. The authors conclude that the project, as planned, should provide an optimal mix of both economic and environmental benefits.This paper is modified from a presentation given to the 1993 Annual Meeting of the International Association for Impact Assessment (IAIA) in Shanghai, China.     

Environmental impact assessment in ghana-anex post evaluation of the volta resettlement scheme: the case of the Kpong Hydro-electric project

Summary Many Third World Countries (TWCs), like Ghana, have not concerned themselves seriously with environmental problems as part of the entire socio-economic development process, until recently. This, for example, can be seen in their environmental policies and the rate at which these now are being made. Not only are environmental issues being considered in the formulation and implementation of new development programmes and projects, but it is being realised that earlier implemented projects need some evaluation,ex post, for possible, correction of past mistakes or, at least, as a source of self-containment. Thus, there has been interest in the impact assessment of past macro-projects as agricultural and resettlement schemes.An attempt is made to apply a simple matrices methodology to theex post evaluation of the Kpong Hydro-electric Project resettlement aspect, based on identified project and environment components. The results show that the impact on the socio- economic life of the settlers is positively greater than the physical and biological impacts. But considering other elements of the programme package and taking a perspective view, the settlers are after all, no better off. In view of the fact that a number of such schemes are now under consideration, it is useful for policy-makers and planners to learn from these lessons.Sam Ofori-Cudjoe is a Lecturer in Geography at the University of Cape Coast, Ghana.

The legacy of migration in response to climate stress: learning from the Gilbertese resettlement in the Solomon Islands

The long‐term threat of sea‐level rise to coral atoll and reef island communities in Kiribati, Tuvalu and other nations has raised the possibility of international migration. Historical resettlements in the Pacific may provide valuable insight into the long‐term effect of future climate change‐related migration on communities. This study evaluates the challenges faced by Gilbertese people resettled from modern‐day Kiribati to Ghizo in the Solomon Islands by the British colonial administration in the mid‐1900s. Drawing upon field interviews (n = 45) conducted in 2011 and the available historical literature, the study examines the circumstances of the initial failed resettlement in the equatorial Phoenix Islands, the subsequent relocation to Ghizo, and the recent concerns of the Gilbertese in Ghizo. Focus is placed on the struggle to recover from the 2007 tsunami that devastated the unprepared community. The analysis reveals that uncertainty about land tenure (raised by 61% of respondents) persists 60 years after resettlement, and is linked to the ability to recover from the tsunami, tensions with the Melanesian population, concerns over political representation, cultural decline, and education and employment opportunities. The Gilbertese experience can serve as a cautionary tale for policymakers considering mechanisms for facilitating climate change‐related migration.     

River systems as providers of goods and services: a basis for comparing desired and undesired effects of large dam projects

In developing countries, large dam projects continue to be launched, primarily to secure a time-stable freshwater supply and to generate hydropower. Meanwhile, calls for environmentally sustainable development put pressure on the dam-building industry to integrate ecological concerns in project planning and decision-making. Such integration requires environmental impact statements (EISs) that can communicate the societal implications of the ecological effects in terms that are understandable and useful to planners and decision-makers. The purpose of this study is to develop a basic framework for assessing the societal implications of the river ecological effects expected of a proposed large dam project. The aim is to facilitate a comparison of desired and potential undesired effects on-site and downstream. The study involves two main tasks: to identify key river goods and services that a river system may provide, and to analyze how the implementation of a large dam project may alter the on-site capacity and downstream potentials to derive river goods and services from the river system. Three river goods and six river services are identified. River goods are defined as extractable partly man-made products and river services as naturally sustained processes. By four main types of flow manipulations, a large dam project improves the on-site capacity to derive desired river goods, but simultaneously threatens the provision of desirable river goods and services downstream. However, by adjusting the site, design, and operational schedule of the proposed dam project, undesirable effects on river goods and services can be minimized.     

Applying outcome evaluation and measures to environmental management programs

Environmental program and audit procedures primarily focus on solving perceived immediate problems and do not provide a context within which to evaluate the work and its importance for the decision maker. Outcome evaluation offers a theory-based model for designing long-term solutions based on stakeholder expectation and, ultimately, ownership of the performance changes. Problem identification as well as the development of actions and their measurement are done with the full participation of those responsible for the implementation of the changes. Ownership of the results is reinforced and, significantly, the decision maker and other interested parties can measure the value or the importance of the work. This article describes how outcome evaluation can be an important tool for federal environmental managers who must respond to the Government Performance and Results Act (1993) and privatesector companies. Used in combination with traditional environmental practices, outcome evaluation can contribute to both the design and the implementation of a successful environmental management program.     

Local Responses to Inundation and De-Farming in the Reservoir Region of the Three Gorges Project (China)

Large-scale infrastructural developments in rural areas often impose significant direct and indirect impacts on environment and people. The Three Gorges Project to dam the Yangtze River in China will create a huge reservoir, inundate farmlands and villages, and incur large-scale resettlement. The concurrent de-farming program to reforest marginal farmlands on steep slopes imposes additional stresses on local people. This study evaluates the ecological and economic adjustments in rural areas affected by both projects, and explores villagers’ knowledge, attitudes, perceptions, and expectations vis-à-vis the drastic changes. Eleven villages in Yunyang County in Sichuan Province, stratified into three zones based on topography and agriculture, were assessed by field studies, questionnaire surveys, maps, satellite imagery, and census and government reports. Multiple regressions identified predictors for 17 dependent variables. Spatial variations in the difficult terrain imposed zone-differentiated agricultural constraints, ecological impacts, and human responses. The dominant farming population—mainly young adults working as migrant laborers in cities—has adopted some nonagricultural work to supplement incomes. Expected per-capita standardized farmland (SF) exceeded threshold SF, which surpasses existing SF. Motivations to reclaim more farmlands, de-farm marginal lands, and become migrant laborers were explained by different multiple-regression predictors. Reduction in farmland stock by inundation and de-farming, aggravated by unwillingness towards nonlocal resettlement, would impose ecological pressures and stimulate demands for nonfarming incomes. Common anticipation of better future income and occupation has been subdued by unfavorable feedbacks from early relocatees. Future environmental and landscape changes are hinged upon changing human responses. Government policies could be informed by research findings to match economic, ecological, and social realities.     

The Atatürk Dam project in south-east Turkey: Changes in objectives and planning over time

The Atatürk Dam was constructed on the Euphrates River in Turkey in the 1980s as the central component of a large-scale regional development project for the South-eastern Anatolia region, known as GAP. Since the first development plan for the region was presented in 1970, the objectives for regional development have changed significantly.
This article aims to analyze how the functions, design, and capacities of the Atatürk Dam project have been modified since 1970, paralleling changes in the regional development objectives and ambitions, and to identify accomplishments and constraints in the realization of the dam project.
Since 1970, ambitions to develop the region have grown significantly, resulting in major changes to the original project plans. The most important change occurred in 1978, when the design for the Middle Karababa Dam, recommended in 1970, was abandoned and the Atatürk Dam design was adopted. This change considerably increased the storage and power generation capacities of the dam. Yet, the sparse rainfall throughout the catchment in recent years has hampered full utilization of the dam's storage and generation capacities and increased the need for tradeoffs between conflicting demands for water use.     

Sustainable Development and Environmental Impact Assessment in Egypt: Historical Assessment

The achievement of sustainable development demands the integration of environment and development. To achieve sustainable development requires a close collaboration and cooperation between environmentalists and the decision-makers. The evidence is that in developing countries (Egypt, as an example) the gap is widening rather than closing. Intensive research programs are needed, for instance in the field of sustainable development and urban environmental management, to narrow that gap. Environmental Impact Assessment (EIA) has become a management tool for achieving acceptable forms of environmentally sound development and sustainability; at best it is proving nothing more than a permit to move a project ahead.It is recommended that indicators for sustainable development and their progress be fully monitored. Performance indicators should always be established, not only for project implementation, but also during and after the implementation process to make sure that all mitigation measures are satisfactorily implemented. This can be achieved by linking the license granting authority for action to the actual implementation of these measures. To secure the environmental sustainability of an environmental project, it is also important to have the EIA document as an integral part of the license application document, and to make it available to inspectors during their necessarily frequent inspection visits.

Political benefits as barriers to assessment of environmental costs in Brazil's Amazonian development planning: The example of the Jatapu Dam in Roraima

Development projects are rapidly changing the landscape in Brazilian Amazonia. Environmental impact assessments have been required since 1986, and the regulatory system is evolving as precedents are set by each new development project. The Jatapu Dam in Roraima provides an illustration of underlying impediments to assessment of environmental costs and to due consideration being given to these assessments when decisions are made. The high priority placed on the dam by the Roraima state government is unexplainable in terms of economic returns. The place of the dam in a long-term political strategy provides the best of several possible explanations, any one of which is incompatible with a rational weighing of economic and environmental costs and benefits. A number of lessons can be drawn from the experience of Jatapu, but some of the problems have no solution. The barriers to rational decision making illustrated by Jatapu apply to development projects in many parts of the world.     

A social topography of home and horizon: The misfit, the dutiful, and longing for home

The environmental perception wave at Clark University was already in full swing when Anne Buttimer arrived in Fall 1970 with curiosities about social space, ‘insiders’ and ‘outsiders’, ‘home’ and ‘reach’, from a project on residential area design in Glasgow, Scotland. Lessons learned from the intense interaction between geographers and psychologists were enormously valuable for subsequent work with geography students at Clark during the 1970s. Since then she has worked on temporality and environmental experience, migration and identity, with colleagues in Sweden, and has pursued autobiographically-based approaches to questions of creativity and context and the history of geographic thought and practice. In retrospect, she claims, one of the most valuable results of the perception wave was to provoke awareness of the lenses through which reality is experienced by people in different cultures, and that includes the disciplinary cultures into which researchers themselves are socialized.     

Modeling the costs and benefits of dam construction from a multidisciplinary perspective

Although the benefits of dam construction are numerous, particularly in the context of climate change and growing global demand for electricity, recent experience has shown that many dams have serious negative environmental, human, and political consequences. Despite an extensive literature documenting the benefits and costs of dams from a single disciplinary perspective, few studies have simultaneously evaluated the distribution of biophysical, socio-economic, and geopolitical implications of dams. To meet the simultaneous demands for water, energy, and environmental protection well into the future, a broader view of dams is needed. We thus propose a new tool for evaluating the relative costs and benefits of dam construction based on multi-objective planning techniques. The Integrative Dam Assessment Modeling (IDAM) tool is designed to integrate biophysical, socio-economic, and geopolitical perspectives into a single cost/benefit analysis of dam construction. Each of 27 different impacts of dam construction is evaluated both objectively (e.g., flood protection, as measured by RYI years) and subjectively (i.e., the valuation of said flood protection) by a team of decision-makers. By providing a visual representation of the various costs and benefits associated with two or more dams, the IDAM tool allows decision-makers to evaluate alternatives and to articulate priorities associated with a dam project, making the decision process about dams more informed and more transparent. For all of these reasons, we believe that the IDAM tool represents an important evolutionary step in dam evaluation.     

Planning for environmental project implementation and development: as exemplified by the songklha lake basin planning study,Thailand

Summary This paper describes use of the economic-cumenvironmental regional development planning process (as differentiated from regional economic planning and regional environmental planning) for its first application in the Asia-Pacific region, for The Songkhla Lake Basin Planning Study, in southern Thailand. The study project was carried out, with Asian Development Bank (ADB) loan financing, as a joint venture of the national economic and national environmental planning agencies. Because of its pioneering nature, in both technical and institutional aspects, numerous lessons were learned from the project. These are described, and yield guidelines valuable for future studies of this type.Dr Harvey F. Ludwig, Chairman of Seatec International Consulting Engineers in Bangkok, has a unique record of distinguished experience in environmental engineering. This includes, in addition to his present role, experience as a professor at the University of California at Berkeley, in research (four USA national awards), in government (as Assistant Chief Engineer of the US Public Health Service Engineering Group, the predecessor to USEPA), and with numerous international assistance agencies including the World Bank, ADB, and many UN affiliates. Dr Ludwig moved to live in Bangkok in 1973 and has since been a continuing adviser to the National Environment Board of Thailand and to the Institutes of Water Resources Research of Indonesia. He is the author/coauthor of some 160 professional publications and the senior author of a textbook onEnvironmental Technology in Developing Countries, now being printed by CRC Press of Boca Raton, Florida. His work record includes projects in more than 30 Developing countries.     

Environmental Impacts of Brazil's Tucuruí Dam: Unlearned Lessons for Hydroelectric Development in Amazonia

Brazil's Tucuruí Dam provides valuable lessons for improving decision-making on major public works in Amazonia and elsewhere. Together with social impacts, which were reviewed in a companion paper, the project's environmental costs are substantial. Monetary costs include costs of construction and maintenance and opportunity costs of natural resources (such as timber) and of the money invested by the Brazilian government. Environmental costs include forest loss, leading to both loss of natural ecosystems and to greenhouse gas emissions. Aquatic ecosystems are heavily affected by the blockage of fish migration and by creation of anoxic environments. Decay of vegetation left in the reservoir creates anoxic water that can corrode turbines, as well as producing methane and providing conditions for methylation of mercury. Defoliants were considered for removing forest in the submergence area but plans were aborted amid a public controversy. Another controversy surrounded impacts of defoliants used to prevent regrowth along the transmission line. Mitigation measures included archaeological and faunal salvage and creation of a “gene bank” on an island in the reservoir. Decision-making in the case of Tucuruí was virtually uninfluenced by environmental studies, which were done concurrently with construction. The dam predates Brazil's 1986 requirement of an Environmental Impact Assessment. Despite limitations, research results provide valuable information for future dams. Extensive public-relations use of the research effort and of mitigation measures such as faunal salvage were evident. Decision-making was closely linked to the influence of construction firms, the military, and foreign financial interests in both the construction project and the use of the resulting electrical power (most of which is used for aluminum smelting). Social and environmental costs received virtually no consideration when decisions were made, an outcome facilitated by a curtain of secrecy surrounding many aspects of the project. Despite improvements in Brazil's system of environmental impact assessment since the Tucuruí reservoir was filled in 1984, many essential features of the decision-making system remain unchanged.     

Role of a Comprehensive Toxicity Assessment and Monitoring Program in the Management and Ecological Recovery of a Wastewater Receiving Stream

National Pollution Discharge Elimination Permit (NPDES)-driven effluent toxicity tests using Ceriodaphnia dubia and fathead minnows were conducted for more than 20 years to assess and monitor the effects of wastewaters at the United States (U.S.) Department of Energy Y-12 National Security Complex (Y-12 Complex) in Oak Ridge, Tennessee. Toxicity testing was also conducted on water samples from East Fork Poplar Creek (EFPC), the wastewater receiving stream, as part of a comprehensive biological monitoring and assessment program. In this paper, we evaluate the roles of this long-term toxicity assessment and monitoring program in the management and ecological recovery of EFPC. Effluent toxicity testing, associated toxicant evaluation studies, and ambient toxicity monitoring were instrumental in identifying toxicant sources at the Y-12 Complex, guiding modifications to wastewater treatment procedures, and assessing the success of various pollution-abatement actions. The elimination of untreated wastewater discharges, the dechlorination of remaining wastewater streams, and the implementation of flow management at the stream headwaters were the primary actions associated with significant reductions in the toxicity of stream water in the upper reaches of EFPC from the late 1980s through mid 1990s. Through time, as regulatory requirements changed and water quality improved, emphasis shifted from comprehensive toxicity assessments to more focused toxicity monitoring efforts. Ambient toxicity testing with C. dubia and fathead minnows was supplemented with less-standardized but more sensitive alternative laboratory toxicity tests and in situ bioassays. The Y-12 Complex biological monitoring experience demonstrates the value of toxicity studies to the management of a wastewater receiving stream.

Evaluating public participation in environmental decision-making: EPA's superfund community involvement program

This article discusses an 8-year, ongoing project that evaluates the Environmental Protection Agency's Superfund community involvement program. The project originated as a response to the Government Performance and Results Act, which requires federal agencies to articulate program goals, and evaluate and report their progress in meeting those goals. The evaluation project assesses how effective the Superfund community involvement program is in promoting public participation in decisions about how to clean up hazardous wastes at Superfund sites. We do three things in the article: (1) share our experience with evaluating an Agency public participation program, including lessons learned about methods of evaluation; (2) report evaluation results; and (3) address a number of issues pertaining to the evaluation of public participation in environmental decision-making. Our goal is to encourage more environmental managers to incorporate evaluation into their public participation programs as a tool for improving them. We found that written mail surveys were an effective and economical tool for obtaining feedback on EPA's community involvement program at Superfund sites. The evaluation focused on four criteria: citizen satisfaction with EPA information about the Superfund site, citizen understanding of environmental and human health risks associated with the site, citizen satisfaction with opportunities provided by EPA for community input, and citizen satisfaction with EPA's response to community input. While the evaluation results were mixed, in general, community members who were most informed about and involved in the cleanup process at Superfund sites generally were also the most satisfied with the community involvement process, and the job that EPA was doing cleaning up the site. We conclude that systematic evaluation provides meaningful and useful information that agencies can use to improve their public participation programs. However, there need to be institutionalized processes that ensure evaluation results are used to develop and implement strategies for improvement.     

Garnering input for recycling communication strategies at a Big Ten University

With increasing environmental challenges confronting our planet, colleges and universities are trying different approaches for minimizing their adverse environmental impacts. Among the approaches being used to revitalize campus sustainability efforts, new waste management strategies have included attempts to improve campus-recycling programs. This paper presents select findings from a comprehensive study at a large, Tier I university aimed at, among other things, informing university administration and decision makers working on the planning and implementation of a new campus-wide recycling facility and program. The researchers used a mixed-method approach to help them develop an understanding of the campus community's (1) perceived barriers to recycling, (2) recycling knowledge, (3) program preferences, and (4) environmental attitudes. The results from a web-based survey (n = 3896, RR1 = 24.9%) suggest, communication efforts for recycling programming should focus more on messages concerning what, how, and where to recycle rather than messages on why to recycle. Furthermore, the results suggest recycling-related publicity approaches should differentiate their mode and content for different segments of the community.     

Exporting dams: China's hydropower industry goes global

In line with China's "going out" strategy, China's dam industry has in recent years significantly expanded its involvement in overseas markets. The Chinese Export-Import Bank and other Chinese financial institutions, state-owned enterprises, and private firms are now involved in at least 93 major dam projects overseas. The Chinese government sees the new global role played by China's dam industry as a "win-win" situation for China and host countries involved. But evidence from project sites such as the Merowe Dam in Sudan demonstrates that these dams have unrecognized social and environmental costs for host communities. Chinese dam builders have yet to adopt internationally accepted social and environmental standards for large infrastructure development that can assure these costs are adequately taken into account. But the Chinese government is becoming increasingly aware of the challenge and the necessity of promoting environmentally and socially sound investments overseas.     

The impact of direct and indirect experiences on the development of environmental knowledge, attitudes, and behavior

This study employed a mixed-methods design to examine the relationship between nature experience type (e.g., direct and indirect) and learning outcomes (e.g., environmental knowledge, attitudes, and behavior) associated with an environmental education, international immersion program for adolescents. Longitudinal data from 108 participant and 49 comparison group members were analyzed to test the study’s hypotheses. Additionally, qualitative data were analyzed using grounded theory methodology to assess participants’ perceptions of these processes. The findings indicate that environmental knowledge increased more than environmental attitudes during the indirect portion of the program (i.e., preparatory program) whereas the direct portion (i.e., international workshop) produced similar levels of knowledge and attitude growth. Further, while attitudes were more strongly associated with behavior during the indirect component of the program, the strength of the relationships between attitudes and behavior, and knowledge and behavior were similar during the direct portion of the experience. A synthesis of the findings suggests that the program’s direct experiences catalyzed environmental knowledge into a stronger motivating force than it had been during the indirect experiences. The qualitative findings also provide insights into the characteristics of direct experiences. These findings offer important insights for both theory and practice related to the use of direct and indirect nature experiences to develop environmental knowledge, attitude, and behaviors.
