DOWNLOAD EBOOK"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.
Constructed Wetlands for Wastewater Treatment

DOWNLOAD EBOOKBoth practical and theoretical, this book provides the basic principles of soil chemistry, hydrology, wetland ecology, microbiology, vegetation and wildlife as a sound introduction to this innovative technology to treat toxic wastewaters and sludges. The use of wetlands for acid mine drainage, and metals removal in municipal, urban runoff, and industrial systems is discussed. Case histories are also presented, demonstrating specific types of constructed wetlands and applications to municipal wastewater, home sites, coal and non-coal mining, coal-fired electric power plants, chemical and pulp industry, agriculture, landfill leachate, and urban stormwater. Construction and management guidelines are clearly explained, providing information on applicable policies and regulations, siting and construction, and operations and monitoring of constructed wetlands treatment systems. Recent theoretical and empirical results from operating systems and research facilities, including such new applications as nutrient removal from eutrophic lakes and urban stormwater treatment within highway rights-of-way, are included. This book is an ideal resource for wastewater treatment plants, consulting engineers, federal and state regulators, industrial environmental managers, municipalities, environmental health professionals, and ecologists.
Wetlands, agriculture and poverty reduction

DOWNLOAD EBOOKIn many places, growing population, in conjunction with efforts to increase food security, is escalating pressure to expand agriculture within wetlands. The environmental impact of wetland agriculture can have profound social and economic repercussions for people dependent on ecosystem services other than those provided directly by agriculture. If wetlands are not used sustainably, the functions which support agriculture, as well as other food security and ecosystem services, are undermined. This report synthesizes findings from multidisciplinary studies conducted into sustainable wetland agriculture by IWMI and partners in Africa and Asia. It highlights the value of wetland agriculture for poverty reduction as well as the need for more systematic planning that takes into account trade-offs in the multiple services that wetlands provide.
Wetlands in a Dry Land

DOWNLOAD EBOOKIn 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.

DOWNLOAD EBOOKThis book contains papers presented at the International Workshop on Tropical Wetlands, held in Banjarmasin, Indonesia. This workshop discussed wetland mapping and characterization as well as wetland management for sustainable agriculture. This volume contains selected papers on tropical wetlands, more specifically, peatland, tidal land, and acid sulphate soils. This book presents an international overview of wetland and peatland mapping experiences from Indonesia, Congo, Brazil, Australia, and Scotland. Several innovative techniques are discussed, including integrated digital soil mapping and remote sensing techniques, as well as geodatabase processing and field surveying. This book further discussed tropical wetland management for agriculture as practiced in Indonesia, Vietnam, and Thailand. The contents of this book are suitable and should be a good reference for those who are involved in research, development, and management of tropical wetland, including academics, soil scientists, environmentalists, researchers, agriculturists, students, agri-businessmen, policy makers, land managers and farmers.
Fens and Bogs in the Netherlands: Vegetation, History, Nutrient Dynamics and Conservation

ISBN-13: 9401579970
DOWNLOAD EBOOKThis volume focuses on the geology, land use history, palaeoecology, ecology and conservation of peatlands (fens and bogs) in The Netherlands. The volume provides detailed accounts that, together, give a representative picture of the studies that have been carried out in the Dutch mires over the past 25 years. Contents: Chapter 1: Verhoeven -- Introduction. Chapter 2: Pons -- is a comprehensive geographic and pedological account of peat formation in space and time in the western coastal plain. Chapter 3: Casparia and Streefkerk -- is a detailed description of the various stages of development from fen to bog of the Bourtanger Moor. Chapter 4: Borger and Stol -- details the history of peat draining, digging and dredging in The Netherlands and Flanders. Chapter 5: Barkman -- deals with bog remnants in the eastern Netherlands and northwestern Germany. This chapter also includes data on oligotrophic heath pools which have a vegetation that is similar to that found in bogs. Chapters 6: Den Held; 7: Van Wirdum et al.; 8: Koerselman and Verhoeven -- are chapters on vegetation, synecology and nutrient dynamics of fens and chapter 9: Wiegers -- focuses mainly on terrestrializing fens that are so characteristic of the western Netherlands where they presently occur in turf ponds created by peat dredging in former centuries. Chapter 10: Vermeer and Joosten -- concludes the volume with a treatment of problems with mire conservation and management.

DOWNLOAD EBOOKThis open access book focuses on the practical application of electromagnetic polarimetry principles in Earth remote sensing with an educational purpose. In the last decade, the operations from fully polarimetric synthetic aperture radar such as the Japanese ALOS/PalSAR, the Canadian Radarsat-2 and the German TerraSAR-X and their easy data access for scientific use have developed further the research and data applications at L,C and X band. As a consequence, the wider distribution of polarimetric data sets across the remote sensing community boosted activity and development in polarimetric SAR applications, also in view of future missions. Numerous experiments with real data from spaceborne platforms are shown, with the aim of giving an up-to-date and complete treatment of the unique benefits of fully polarimetric synthetic aperture radar data in five different domains: forest, agriculture, cryosphere, urban and oceans.
