Wetlands in a Dry Land


Book Description

In the name of agriculture, urban growth, and disease control, humans have drained, filled, or otherwise destroyed nearly 87 percent of the world’s wetlands over the past three centuries. Unintended consequences include biodiversity loss, poor water quality, and the erosion of cultural sites, and only in the past few decades have wetlands been widely recognized as worth preserving. Emily O’Gorman asks, What has counted as a wetland, for whom, and with what consequences? Using the Murray-Darling Basin—a massive river system in eastern Australia that includes over 30,000 wetland areas—as a case study and drawing on archival research and original interviews, O’Gorman examines how people and animals have shaped wetlands from the late nineteenth century to today. She illuminates deeper dynamics by relating how Aboriginal peoples acted then and now as custodians of the landscape, despite the policies of the Australian government; how the movements of water birds affected farmers; and how mosquitoes have defied efforts to fully understand, let alone control, them. Situating the region’s history within global environmental humanities conversations, O’Gorman argues that we need to understand wetlands as socioecological landscapes in order to create new kinds of relationships with and futures for these places.




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.




Coastal Wetlands


Book Description

Coastal wetlands are under a great deal of pressure from the dual forces of rising sea level and the intervention of human populations both along the estuary and in the river catchment. Direct impacts include the destruction or degradation of wetlands from land reclamation and infrastructures. Indirect impacts derive from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. As sea level rises, coastal wetlands in most areas of the world migrate landward to occupy former uplands. The competition of these lands from human development is intensifying, making the landward migration impossible in many cases. This book provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide, and suggestions for their management. In this book a CD is included containing color figures of wetlands and estuaries in different parts of the world. - Includes a CD containing color figures of wetlands and estuaries in different parts of the world.




Wetland Ecology


Book Description

This text provides a synthesis of the existing field of wetland ecology using a few central themes, including key environmental factors that produce wetland community types and some unifying problems such as assembly rules, restoration and conservation.




Over in the Wetlands


Book Description

Publishing in time for the tenth anniversary of Hurricane Katrina, here is a beautiful read-aloud about animal families preparing for an impending storm in their bayou habitat. Journey to the Louisiana wetlands and watch as all the animals of the bayou experience one of nature’s most dramatic and awe-inspiring events: a hurricane. The animals prepare—swimming for safer seas, finding cover in dens, and nestling their young close to protect them. During the height of the storm, even the trees react, cracking and moaning in the wind. At last, the hurricane yawns and rests, and animals come out to explore their world anew.




Swamplands


Book Description

In a world filled with breathtaking beauty, we have often overlooked the elusive magic of certain landscapes. A cloudy river flows into an Arctic wetland where sandhill cranes and muskoxen dwell. Further south, cypress branches hang low over dismal swamps. Places like these-collectively known as swamplands or peatlands-often go unnoticed for their ecological splendor. They are as globally significant as rainforests, yet, because of their reputation as wastelands, they are being systematically drained and degraded. Swamplands celebrates these wild places, as journalist Edward Struzik highlights the unappreciated struggle to save peatlands by scientists, conservationists, and landowners around the world. An ode to peaty landscapes in all their offbeat glory, the book is also a demand for awareness of the myriad threats they face. It inspires us to see the beauty and importance in these least likely of places­. Our planet's survival might depend on it.




Wetland Carbon and Environmental Management


Book Description

Explores how the management of wetlands can influence carbon storage and fluxes. Wetlands are vital natural assets, including their ability to take-up atmospheric carbon and restrict subsequent carbon loss to facilitate long-term storage. They can be deliberately managed to provide a natural solution to mitigate climate change, as well as to help offset direct losses of wetlands from various land-use changes and natural drivers. Wetland Carbon and Environmental Management presents a collection of wetland research studies from around the world to demonstrate how environmental management can improve carbon sequestration while enhancing wetland health and function. Volume highlights include: Overview of carbon storage in the landscape Introduction to wetland management practices Comparisons of natural, managed, and converted wetlands Impact of wetland management on carbon storage or loss Techniques for scientific assessment of wetland carbon processes Case studies covering tropical, coastal, inland, and northern wetlands Primer for carbon offset trading programs and how wetlands might contribute The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity.Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.




Wetlands


Book Description

"Wetlands" has become a hot word in the current environmental debate. But what does it signify? In 1991, proposed changes in the legal definities of wetlands stirred controversy and focused attention on the scientific and economic aspects of their management. This volume explores how to define wetlands. The committee--whose members were drawn from academia, government, business, and the environmental community--builds a rational, scientific basis for delineating wetlands in the landscape and offers recommendations for further action. Wetlands also discusses the diverse hydrological and ecological functions of wetlands, and makes recommendations concerning so-called controversial areas such as permafrost wetlands, riparian ecosystems, irregularly flooded sites, and agricultural wetlands. It presents criteria for identifying wetlands and explores the problems of applying those criteria when there are seasonal changes in water levels. This comprehensive and practical volume will be of interest to environmental scientists and advocates, hydrologists, policymakers, regulators, faculty, researchers, and students of environmental studies.
