Wetlands are among the most important natural resources on earth, as sources of biological, cultural and economic diversity. Conservation and management of wetlands have been identified as priority tasks for action in international conventions and regional policies, but extensive wetland area has been degraded in many developing countries. These continuing destruction demands to be restricted or at least slowed down. The primary objectives of this study were (i) assessing ecological functions and concepts for sustainable use of wetlands and (ii) compiling relevant information sources on geographic distribution of wetlands as well as their role in the global carbon budget. Wetlands comprise a pivotal global carbon reservoir and can moreover sequester additional carbon from the atmosphere in form of soil organic matter. Pristine wetland soils are a source of the greenhouse gas methane, but -- under improper management -- these soils emit even larger quantities of the greenhouse gas carbon dioxide. The discussion on wetland protection measures is thwarted by uncertainties in the estimated carbon pool sizes and flux rates. On the global scale, the estimates on the carbon pool size vary from 200 to 530 Gt C while our own assessment (by incorporating global soil maps) clearly points towards the lower end of this range. Likewise, estimates of the carbon sequestration potential of wetlands vary between 80 to 230 Tg C/ yr. These discrepancies may in part be due to inherent problems in global land cover surveys, but diverging definitions of the ecosystem 'wetlands' (especially in dealing with peatlands) are further confounding an appraisal of global wetland resources. Similar uncertainties as for the global estimates arise for the geographic distribution of wetlands as described in different data sources. The three published world maps on wetland resources only coincide in 20-30 % of the identified wetland area. Our compilation of data on quantity and distribution of the wetland carbon pool allows an identification of potential 'hot spots' of future emissions and could feed into development of research and conservation projects. There are many reasons in favor of protection or a 'wise use' of wetlands that maintains the basic features of the ecosystem. The significance of wetlands for the global carbon budget and thus, for climate change, is a crucial pro-conservation argument that has been substantiated in this study through findings from current research.

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.

The signals are everywhere that our planet is experiencing significant climate change. It is clear that we need to reduce the emissions of carbon dioxide and other greenhouse gases from our atmosphere if we want to avoid greatly increased risk of damage from climate change. Aggressively pursuing a program of emissions abatement or mitigation will show results over a timescale of many decades. How do we actively remove carbon dioxide from the atmosphere to make a bigger difference more quickly? As one of a two-book report, this volume of Climate Intervention discusses CDR, the carbon dioxide removal of greenhouse gas emissions from the atmosphere and sequestration of it in perpetuity. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration introduces possible CDR approaches and then discusses them in depth. Land management practices, such as low-till agriculture, reforestation and afforestation, ocean iron fertilization, and land-and-ocean-based accelerated weathering, could amplify the rates of processes that are already occurring as part of the natural carbon cycle. Other CDR approaches, such as bioenergy with carbon capture and sequestration, direct air capture and sequestration, and traditional carbon capture and sequestration, seek to capture CO2 from the atmosphere and dispose of it by pumping it underground at high pressure. This book looks at the pros and cons of these options and estimates possible rates of removal and total amounts that might be removed via these methods. With whatever portfolio of technologies the transition is achieved, eliminating the carbon dioxide emissions from the global energy and transportation systems will pose an enormous technical, economic, and social challenge that will likely take decades of concerted effort to achieve. Climate Intervention: Carbon Dioxide Removal and Reliable Sequestration will help to better understand the potential cost and performance of CDR strategies to inform debate and decision making as we work to stabilize and reduce atmospheric concentrations of carbon dioxide.

New focused text introduces readers to wetland ecosystems and systems approaches to studying wetlands With its comprehensive coverage of wetland science, management, and restoration, Mitsch and Gosselink's Wetlands has been the premier reference on wetlands for more than two decades. Now, the coverage of specific wetland ecosystem types from earlier editions of this acclaimed work has been updated, revised, and supplemented with additional content in order to create this new text focusing exclusively on wetland ecosystems. This book now complements Wetlands, Fourth Edition. Following an introduction to ecosystems in general and wetland ecosystems in particular, Wetland Ecosystems examines the major types of wetlands found throughout the world: coastal wetlands, freshwater marshes and forested swamps, and peatlands. The final chapter reviews three fundamental systems approaches to studying wetlands: mesocosms, full-scale experimental ecosystems, and mathematical modeling. This new text features: Updated descriptions of the hydrology, biogeochemistry, and biology of the main types of wetlands found in the world New content introducing general ecosystems, wetland ecosystems, whole ecosystem and mesocosm experiments with wetlands, and systems ecology and modeling A detailed description of the ecosystem services provided by wetlands A broad international scope, including many examples of wetlands located outside North America Two new coauthors offering new perspectives and additional insights into the latest ecosystem and modeling techniques An abundance of illustrations helps readers understand how different biological communities and the abiotic environment in wetland ecosystems interact and function. Tables and text boxes provide at-a-glance summaries of key information. Lastly, each chapter concludes with a list of recommended readings. This text has been designed as an introduction for students and professionals in wetland ecology and management, general ecology, environmental science, and natural resource management.

Wetlands are usually located in complex landscapes. Multiple ecosystem services delivered by wetlands to human well-being should be considered in broader contexts of wetland functions, water quality, water resource management and wetland conservation. Natural wetlands are 'kidneys' and 'sponges' of the earth that remove water pollutants and provide hydrological regulation functions vital to the environment. Where the functions of the wetlands are weakened, actions of rehabilitations are needed to revitalize those functions. While worldwide many natural wetlands have disappeared due to climate change and/or human activities, constructed wetlands, which may be seen as 'artificial kidneys/sponges' of the earth, have been increasingly built to replicate the functions of the natural wetlands. This Research Topic aims to collect and present the latest research developments in natural and constructed wetlands in relation to either water resource functions or water quality. Articles published in this Research Topic will showcase new understandings of water balances and flow patterns, vegetation characteristics, and pollutant transformations in wetland systems; innovative designs and efficiencies of wastewater treatment wetlands; and technologies that revitalize the ecosystem functions of natural wetlands. These articles are expected to bring benefits to research communities, water and wastewater industries, and government agencies that deal with wetland water management and conservation. High-quality Original Research and Review articles in this field are all welcome for submission to this Research Topic. Research interests include but are not limited to the following areas: 1. Water balances and flow patterns in natural wetland systems. 2. The hydrological regulation functions and importance of natural wetlands in their environmental context. 3. Vegetation characteristics of natural wetlands and their functional importance in wetland water pollution control. 4. Techniques for the rehabilitation of degraded wetlands. 5. The role of constructed wetlands in wastewater treatment. 6. Innovative designs and efficiencies of wastewater treatment wetlands. 7. The modeling of hydrological and/or pollutant dynamics in wetland systems. 8. The ecohydrology of wetlands. 9. The role of wetlands in the global carbon cycle. 10. Impacts of climate change and human activities on wetland hydrology and water resources. Recognizing that hydrological and biogeochemical processes are basically coupled in wetlands and their landscapes, manuscripts that report their interactions are particularly welcome.
