Odeh (Conte Anadromous Fish Research Center) presents 13 contributions which explore the technical possibilities of constructing effective fish bypass systems for hydroelectric dams, especially those that are due for relicensing in the context of new regulations. The articles consist of case studies in the effectiveness of such techniques as surface bypass systems, modular inclined screens, hydroacoustic evaluation of fish entrainment patterns, surface collection, surface spill gates, and radio-tagging and radar tracking behavior evaluation strategies.

The focus of this report is technologies for fish passage around hydropower generation facilities and protection against entrainment and turbine mortality. Emphasis is given to Federal Energy Regulatory Commission (FERC)-licensed hydropower projects where fish protection is a subject of controversy and congressional interest due to the Federal Power Act (FPA) and the Electric Consumers Protection Act (ECPA). Thus institutional issues related to FERC-relicensing are also discussed. (Major points of controversy are high-lighted in box 1.1).

It has been more than 140 years since water was used to generate electricity. Especially since the 1970s, with the advancement of science and technology, new technologies, new processes, and new materials have been widely used in hydropower construction. Engineering equipment and technology, as well as cascade development, have become increasingly mature, making possible the construction of many high dams and large reservoirs in the world. However, with the passage of time, hydropower infrastructure such as reservoirs, dams, and power stations built in large numbers in the past are aging. This, coupled with singular use of hydropower, limits the development of hydropower in the future. This book reports the achievements in hydropower construction and the efforts of sustainable hydropower development made by various countries around the globe. These existing innovative studies and applications stimulate new ideas for the renewal of hydropower infrastructure and the further improvement of hydropower development and utilization efficiency.

In developing countries, traditional fishermen are important food contributors, yet technological information and development assistance to third-world nations often focuses on agriculture and industrial fishing, without addressing the needs of independent, small-scale fishermen. This book explores technological considerations of small-scale, primitive fishing technologies, and describes innovative, relatively inexpensive methods and tools that have already been successfully applied in developing countries. It offers practical information about all aspects of small-scale fishing, including boat design and construction, fishing methods and gear, artificial reef construction and fish aggregating devices, techniques for coastal mariculture, and simple methods for processing and preserving fish once they are caught. Fisheries Technologies for Developing Countries is illustrated throughout with photographs of the devices and construction methods described in the text.

Safe Passages brings together in a single volume the latest information on the emerging science of road ecology as it relates to mitigating interactions between roads and wildlife. This practical handbook of tools and examples is designed to assist individuals and organizations thinking about or working toward reducing road-wildlife impacts. The book provides: an overview of the importance of habitat connectivity with regard to roads current planning approaches and technologies for mitigating the impacts of highways on both terrestrial and aquatic species different facets of public participation in highway-wildlife connectivity mitigation projects case studies from partnerships across North America that highlight successful on-the-ground implementation of ecological and engineering solutions recent innovative highway-wildlife mitigation developments Detailed case studies span a range of scales, from site-specific wildlife crossing structures, to statewide planning for habitat connectivity, to national legislation. Contributors explore the cooperative efforts that are emerging as a result of diverse organizations—including transportation agencies, land and wildlife management agencies, and nongovernmental organizations—finding common ground to tackle important road ecology issues and problems. Safe Passages is an important new resource for local-, state-, and national-level managers and policymakers working on road-wildlife issues, and will appeal to a broad audience including scientists, agency personnel, planners, land managers, transportation consultants, students, conservation organizations, policymakers, and citizens engaged in road-wildlife mitigation projects.

ÔThere is no debate about the fact that a Òbusiness as usualÓ approach is an environmentally unsustainable one. Given the magnitude of the environmental challenges the world faces today, extensive changes in corporate strategies and significant innovation advances are absolutely necessary if we are to avoid substantial decreases in our quality of living. This set of internationally recognized authors provides some fresh and informative perspectives on this topic along with a path for a more sustainable future.Õ Ð Mark Ferguson, University of South Carolina, US Corporations across the world are becoming increasingly aware of the threat of environmental degradation and the growing importance of sustainable business practices. This raises a vital question: How can for-profit firms (and other profit-conscious enterprises such as government organizations) implement more environmentally friendly policies without sacrificing profitability? This innovative volume tackles that complex question, offering detailed recommendations for making strategic technological choices that are economically advantageous, ecologically sustainable and socially responsible. Expert contributions examine the contextual factors that affect implementation of more sustainable technology and innovation practices, offering a number of empirical methodologies to describe and explain these multidimensional influences. What emerges is a compelling argument in favor of balanced strategies that merge profitability concerns with ecological consciousness, allowing for controlled sustainable development and stable, long-term economic success. Discussion of companies in both developed and emerging countries makes this book useful on a truly global scale. Students and professors of business, management studies and economics will find much to admire in this path-breaking volume. Managers, policymakers and other practitioners will also benefit greatly from this bookÕs timely and insightful recommendations.

Over the last fifty years, human exploitation of marine resources has become more efficient as the understanding of the habits and behaviour of the various species available in the sea gradually increased. Thus, technologies have developed naturally over time and fishing gears and practices have become more sophisticated. These technical advances in fishing gear have generally led to more efficient economic fishing operations and better access to resources. However, fishing implies the harvesting of marine organisms directly from their natural environment, therefore general awareness of environmental problems due to the exploitation of fishery resources has also increased. In particular, the poor selectivity of some gears is responsible for the capture of juveniles, immature and undersized specimens of many species, with negative consequences on the state of stocks. In addition, bycatch in marine fisheries is a major source of human-caused mortality of marine megafauna, often leading to the capture of vulnerable species. Finally, many bottom-towed gears are responsible for high impacts on bottom communities and habitats, with cascading consequences on the entire marine ecosystem. All these impacts can lead to changes in the structure, function and integrity of ecosystems, including effects on the food webs and multispecies predator-prey relationships.
