'In the past two decades there has been considerable work on global climatic change and its effect on the ecosphere, as well as on local and global environmental changes triggered by human activities. From the tropics to the Arctic, peatlands have developed under various geological conditions, and they provide good records of global and local changes since the Late Pleistocene. The objectives of the book are to analyze topics such as geological evolution of major peatlands basins; peatlands as self sustaining ecosystems; chemical environment of peatlands: water and peat chemistry; peatlands as archives of environmental changes; influence of peatlands on atmosphere: circular complex interactions; remote sensing studies of peatlands; peatlands as a resource; peatlands degradation, restoration, plus more.' * Presents an interdisciplinary approach, with an emphasis on Earth Science, and addresses the need for intergration between subdisciplines and the developing of new approaches * Synthesizes the evolutionary, ecological, and chemical characteristics of major peatlands, as well as focuses on the environmental changes, from climate changes to surface ares changes due to human activities * Covers topical studies of worldwide interest and provides examples from many different countries

Peatlands are a unique and fast disappearing landscape. More and more countries are recognising this situation and protective legislation is increasingly being put in place. It is therefore important to understand all the processes and influences that are involved in sustaining the remaining examples of this fragile ecosystem. This book brings together the leading workers in this area. The contributions have been developed from the Peatlands Convention, held in Edinburgh and include a foreword by David Bellamy. The book addresses two key questions: why should peatlands be conserved and how should this be achieved? The first question is answered by chapters that look at the variety, attributes and interest in active bogs and peatlands throughout the world. There are contributions that consider the peat archive and look at how this contains information on the history of the site as well as material of much wider historical relevance. The book includes chapters describing the past and present uses of peatlands and includes discussion about their current commercial exploitation. This book summarises the current situation regarding peatlands and bogs and sets the agenda for their future survival. The work that has been brought together in this volume is important reading for all conservation workers, environmental scientists, ecologists, land managers and farmers working with peatlands and bogs. The book is also relevant to all government policy makers and voluntary bodies involved in sustaining biodiversity.

Into the Peatlands

The peatlands of the Outer Hebrides are half land, half water. Their surface is a glorious tweed woven from tiny, living sphagnums rich in wildlife, but underneath is layer upon layer of dead mosses transforming into the peat. One can, with care, walk out onto them, but stop and you begin to sink into them. For time immemorial the peatlands have been places - for humans at least - of seasonal habitation but not of constant residence.In this book Robin A. Crawford explores the peatlands over the course of the year, explaining how they have come to be and examining how peat has been used from the Bronze Age onwards. In describing the seasonal processes of cutting, drying, stacking, storing and burning he reveals one of the key rhythms of island life, but his study goes well beyond this to include many other aspects, including the wildlife and folklore associated with these lonely, watery places.Widening his gaze to other peatlands in the country, he also reflects on the historical and cultural importance that peat has played, and continues to play - it is still used for fuel in many rural areas and plays an essential role in whisky-making - in the story of Scotland.

The poems in the first full-length collection to be published in the UK by the acclaimed Mexican poet Pedro Serrano are taken from Desplazamientos, a volume of selected poems which draws on all his collections since 1986. Chosen by both the poet and his accomplished translator, Anna Crowe, these poems are wide-ranging, passionate and linguistically thrilling, together forming a beautifully-balanced introduction to Serrano’s work.

Peatlands, climate change mitigation and biodiversity conservation

Did you know that • peatlands hold more carbon than all forests of the world combined? • drained peatlands are responsible for 25% of total CO2 emissions in the Nordic and Baltic countries? • rewetting of peatlands substantially reduces these emissions? This policy brief pleads for increased commitments to conserving and rewetting peatlands; for abolishing regulations that drive peatland drainage; for changing drained peatland use to paludicultures; and for setting up good practice demonstration projects. It stresses the need for better communicating the benefits of wet peatlands and the costs arising from damaged ones. Finally it highlights the role of peatland rewetting and restoration in reaching national and international policy targets for climate change mitigation, water quality improvement and biodiversity conservation.

Due to an awareness of peatlands as a diminishing resource, peatland conservation and rehabilitation has become an important study area. Peatlands and Environmental Change offers a new approach by considering peatlands as a whole ecosystem, and thereby provides a better understanding of the importance and the consequences of the functioning of peatlands. Contents include: * Peat and peatlands * Peat landforms and structure * Peatland hydrology and ecology * Origins and pest initiation * Peat accumulation * The peatland archive: palaeoenvironmental evidence * Autogenic change * Allogenic change * Peatland - environmental feedbacks * Values, exploitation and human impacts * Conservation management and restoration

Peatlands form important landscape elements in many parts of the world and play significant roles for biodiversity and global carbon balance. This new edition has been fully revised and updated, documenting the latest advances in areas such as microbial processes and relations between biological processes and hydrology. As well as thoroughly referencing the latest research, the authors expose a rich older literature where an immense repository of natural history has accumulated. The Biology of Peatlands starts with an overview of the main peatland types (marsh, swamp, fen, and bog), before examining the entire range of biota present (microbes, invertebrates, plants, and vertebrates), together with their specific adaptations to peatland habitats. Detailed coverage is devoted to the genus Sphagnum, the most important functional plant group in northern peatlands, although tropical and southern hemisphere peatlands are also covered. Throughout the book the interactions between organisms and environmental conditions (especially wetness, availability of oxygen, and pH) are emphasized, with chapters on the physical and chemical characteristics of peat, the role of peat as an archive of past vegetation and climate, and peatland succession and development. Several other key factors and processes are then examined, including hydrology and nutrient cycling. The fascinating peatland landforms in different parts of the world are described, together with theories on how they have developed. Human interactions with peatlands are considered in terms of management, conservation, and restoration. A final chapter, new to this edition, focuses on the role of peatlands as sources or sinks for the greenhouse gases carbon dioxide and methane, and the influences of climate change on peatlands. This timely and accessible text is suitable for students and researchers of peatland ecology, as well as providing an authoritative overview for professional ecologists and conservation biologists.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 184. Carbon Cycling in Northern Peatlands examines the role that northern peatlands play in regulating the atmospheric carbon budget. It summarizes current research in four interconnected areas: large-scale peatland dynamics and carbon cycling; plant and microbial dynamics and their effect on carbon fluxes to the atmosphere; methane accumulation in, and loss from, peatlands; and water and dissolved carbon fluxes through peatlands. The volume highlights include A thorough assessment of the challenges involved in incorporating carbon cycling in northern peatlands into global climate models; A conceptual model to examine the partitioning of terminal carbon mineralization into production of CO2 and CH4; A comprehensive review of the evidence for the accumulation of methane in deep and shallow peat; and A description of the hydrologic changes induced by peat harvesting and associated challenges in restoring altered peatlands to their natural hydrologic regime. Carbon Cycling in Northern Peatlands will be of interest to research scientists and graduate and undergraduate students, particularly those who wish to know more about the role of peatlands in the global carbon cycle and their role as modifiers of climate.

The Guayana Highlands in northeastern tropical America, rising from lowland rain forests and savannas up to 3000 m elevation, are characterized by ancient tablelands called tepuis. The peatlands that developed on the tepuis constitute unique and fascinating ecosystems and are the focus of this volume, which starts with an overview of tropical and subtropical peats, followed by an introduction to the geo-ecological features of the Guayana region as a whole, with special emphasis on the diversity of the vegetation cover from lowlands to uplands to highlands. The core subject centers on the properties and dating of the peat deposits and the interpretation of the chronological record in terms of past environmental changes. The well illustrated book will appeal to a broad range of scientists interested in tropical highland peats, including quaternarists, soil scientists, geomorphologists, geographers, geologists, ecologists, botanists, hydrologists, conservationists, and land use planners.

This is the first truly ecosystem-oriented book on peatlands. It adopts an ecosystems approach to understanding the world's boreal peatlands. The focus is on biogeochemical patterns and processes, production, decomposition, and peat accumulation, and it provides additional information on animal and fungal diversity. A recurring theme is the legacy of boreal peatlands as impressive accumulators of carbon as peat over millennia.
