Wetlands and Urbanization


Book Description

Urbanization affects wetlands in direct and indirect ways. Over the past several decades it has become increasingly apparent that unmanaged runoff is the primary threat to the country's watershed resources. Wetlands and Urbanization: Implications for the Future is the result of a ten year research project focused on the understanding and managing the impacts of urban stormwater on wetlands. The book documents the background, methods, and results of the research and uses the information to draw conclusions about managing wetland ecosystems in urban areas. The project culminates in a set of comprehensive guidelines for the management of wetland hydrology. While the focus of this research is regional in nature, its applications are broad. First, the research shows how to measure and assess the impact of urbanization on wetlands. Secondly, it presents scientific approaches available for use in an integrated assessment of wetland condition. And thirdly, it provides guidelines for biomonitoring wetlands using multiple indicators. Wetlands and Urbanization presents an integrated watershed approach to the scientific evaluation of the impact of landscape urbanization on wetland functions. It associates the source of impact (the landscape) with the sink (the wetland), relates findings to implications for future planning and management of watersheds and provides a model for future comprehensive investigations of wetland impacts from urbanization.

Coastal Wetlands: Alteration and Remediation


Book Description

This book delves into human-induced and natural impacts on coastal wetlands, intended or otherwise, through a series of vignettes that elucidate the environmental insults and efforts at amelioration and remediation. The alteration, and subsequent restoration, of wetland habitats remain key issues among coastal scientists. These topics are introduced through case studies and pilot programs that are designed to better understand the best practices of trying to save what is left of these fragile ecosystems. Local approaches, as well as national and international efforts to restore the functionality of marsh systems are summarily approached and evaluated by their efficacy in producing resilient reclamations in terms of climate-smart habitat conservation. The outlook of this work is global in extent and local by intent. Included here in summarized form are professional opinions of experts in the field that investigate the crux of the matter, which proves to be human pressure on coastal wetland environments. Even though conservation and preservation of these delicate environmental systems may be coming at a later date, many multi-pronged approaches show promise through advances in education, litigation, and engineering to achieve sustainable coastal systems. The examples in this book are not only of interest to those working exclusively with coastal wetlands, but also to those working to protect the surrounding coastal areas of all types.




Advanced Studies in Efficient Environmental Design and City Planning


Book Description

This book explains how learning from past mistakes in urban design can help to enhance sustainable cities and how the principles of Green Urbanism can yield more resilient urban settlements. Environmental design is a fundamental principle in shaping cities. However, environmental challenges like increased resource consumption, water degradation and waste-related issues are among the greatest problems now facing humanity – which is why these issues need to be considered with regard to “smart cities,” either for the development of new urban centers or for the transformation of existing cities. The book not only discusses the importance of integrating sustainability principles in the urban design process, but also demonstrates their application to the development of sustainable cities. As such, the book offers essential information and a source of inspiration for all those who want to build more sustainable cities.

Restoration of Aquatic Ecosystems


Book Description

Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.




Compensating for Wetland Losses Under the Clean Water Act


Book Description

Recognizing the importance of wetland protection, the Bush administration in 1988 endorsed the goal of "no net loss" of wetlands. Specifically, it directed that filling of wetlands should be avoided, and minimized when it cannot be avoided. When filling is permitted, compensatory mitigation must be undertaken; that is, wetlands must be restored, created, enhanced, and, in exceptional cases, preserved, to replace the permitted loss of wetland area and function, such as water quality improvement within the watershed. After more than a dozen years, the national commitment to "no net loss" of wetlands has been evaluated. This new book explores the adequacy of science and technology for replacing wetland function and the effectiveness of the federal program of compensatory mitigation in accomplishing the nation's goal of clean water. It examines the regulatory framework for permitting wetland filling and requiring mitigation, compares the mitigation institutions that are in use, and addresses the problems that agencies face in ensuring sustainability of mitigated wetlands over the long term. Gleaning lessons from the mixed results of mitigation efforts to date, the book offers 10 practical guidelines for establishing and monitoring mitigated wetlands. It also recommends that federal, state, and local agencies undertake specific institutional reforms. This book will be important to anyone seeking a comprehensive understanding of the "no net loss" issue: policy makers, regulators, environmental scientists, educators, and wetland advocates.
