All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.

A central goal of transportation is the delivery of safe and efficient services with minimal environmental impact. In practice, though, human mobility has flourished while nature has suffered. Awareness of the environmental impacts of roads is increasing, yet information remains scarce for those interested in studying, understanding, or minimizing the ecological effects of roads and vehicles. Road Ecology addresses that shortcoming by elevating previously localized and fragmented knowledge into a broad and inclusive framework for understanding and developing solutions. The book brings together fourteen leading ecologists and transportation experts to articulate state-of-the-science road ecology principles, and presents specific examples that demonstrate the application of those principles. Diverse theories, concepts, and models in the new field of road ecology are integrated to establish a coherent framework for transportation policy, planning, and projects. Topics examined include: foundations of road ecology roads, vehicles, and transportation planning vegetation and roadsides wildlife populations and mitigation water, sediment, and chemical flows aquatic ecosystems wind, noise, and atmospheric effects road networks and landscape fragmentation Road Ecology links ecological theories and concepts with transportation planning, engineering, and travel behavior. With more than 100 illustrations and examples from around the world, it is an indispensable and pioneering work for anyone involved with transportation, including practitioners and planners in state and province transportation departments, federal agencies, and nongovernmental organizations. The book also opens up an important new research frontier for ecologists.

At the 1992 United Nations Conference on Environment and Development, popularly known as the Rio Earth Summit, the world’s leaders constructed a new "sustainable development" paradigm that promised to enhance environmentally sound economic and social development. Twenty years later, the proliferation of multilateral environmental agreements points to an unprecedented achievement, but is worth examining for its accomplishments and shortcomings. This book provides a review of twenty years of multilateral environmental negotiations (1992-2012). The authors have participated in most of these negotiating processes and use their first-hand knowledge as writers for the International Institute for Sustainable Development’s Earth Negotiations Bulletin as they illustrate the changes that have taken place over the past twenty years. The chapters examine the proliferation of meetings, the changes in the actors and their roles (governments, nongovernmental organizations, secretariats), the interlinkages of issues, the impact of scientific advice, and the challenges of implementation across negotiating processes, including the Framework Convention on Climate Change, the Convention to Combat Desertification, the Convention on Biological Diversity, the Commission on Sustainable Development, the UN Forum on Forests, the chemicals conventions (Stockholm, Basel and Rotterdam), the Montreal Protocol on Substances that Deplete the Ozone Layer, the Convention on International Trade in Endangered Species, the Convention on Migratory Species and the International Treaty on Plant Genetic Resources for Food and Agriculture.

Winner of the IENE Project Award 2016. This authoritative volume brings together some of the world’s leading researchers, academics, practitioners and transportation agency personnel to present the current status of the ecological sustainability of the linear infrastructure – primarily road, rail and utility easements – that dissect and fragment landscapes globally. It outlines the potential impacts, demonstrates how this infrastructure is being improved, and how broad ecological principles are applied to mitigate the impact of road networks on wildlife. Research and monitoring is an important aspect of road ecology, encompassing all phases of a transportation project. This book covers research and monitoring to span the entire project continuum – starting with planning and design, through construction and into maintenance and management. It focuses on impacts and solutions for species groups and specific regions, with particular emphasis on the unique challenges facing Asia, South America and Africa. Other key features: Contributions from authors originating from over 25 countries, including from all continents Each chapter summarizes important lessons, and includes lists of further reading and thoroughly up to date references Highlights principles that address key points relevant to all phases in all road projects Explains best-practices based on a number of successful international case studies Chapters are "stand-alone", but they also build upon and complement each other; extensive cross-referencing directs the reader to relevant material elsewhere in the book Handbook of Road Ecology offers a comprehensive summary of approximately 30 years of global efforts to quantify the impacts of roads and traffic and implement effective mitigation. As such, it is essential reading for those involved in the planning, design, assessment and construction of new roads; the management and maintenance of existing roads; and the modifying or retrofitting of existing roads and problem locations. This handbook is an accessible resource for both developed and developing countries, including government transportation agencies, Government environmental/conservation agencies, NGOs, and road funding and donor organisations.

Content Description #Includes bibliographical references and index.

The Twyford Down story is set in a political and historical framework in order to examine the key issues affecting road planning and environmental protection: the system of route selection; Crown development; government agents, NGOs and locally elected authorities; conservation legislation; subsidiarity; lobbying techniques; and the role of the press. Written in a lively style and vividly illustrated, Twyford Down will appeal to environmental advisors, policy makers and planners as well as lobbyists and those interested in the environment.

This book provides an overview of the ecology of roads and describes the effects of roads and traffic. It discusses the methods for avoiding, remedying and mitigating the adverse effects of roads on the environment, habitats, and plants and animals.
