Book Description
A must-have introduction to this fundamental driver of the climate system The Global Carbon Cycle is a short introduction to this essential geochemical driver of the Earth's climate system, written by one of the world's leading climate-science experts. In this one-of-a-kind primer, David Archer engages readers in clear and simple terms about the many ways the global carbon cycle is woven into our climate system. He begins with a concise overview of the subject, and then looks at the carbon cycle on three different time scales, describing how the cycle interacts with climate in very distinct ways in each. On million-year time scales, feedbacks in the carbon cycle stabilize Earth's climate and oxygen concentrations. Archer explains how on hundred-thousand-year glacial/interglacial time scales, the carbon cycle in the ocean amplifies climate change, and how, on the human time scale of decades, the carbon cycle has been dampening climate change by absorbing fossil-fuel carbon dioxide into the oceans and land biosphere. A central question of the book is whether the carbon cycle could once again act to amplify climate change in centuries to come, for example through melting permafrost peatlands and methane hydrates. The Global Carbon Cycle features a glossary of terms, suggestions for further reading, and explanations of equations, as well as a forward-looking discussion of open questions about the global carbon cycle.

Book Description
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.

Book Description
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

Book Description
The Carbon Balance of Forest Biomes provides an informed synthesis on the current status of forests and their future potential for carbon sequestration. This volume is timely, since convincing models which scale from local to regional carbon fluxes are needed to support these international agreements, whilst criticisms have been levelled at existing empirical approaches. One key question is to determine how well eddy-flux measurements at the stand-level represent regional-scale processes. This may be related to specific management practices (age, plantation, fertilisation) or simple bias in choosing representative sites (ease of access, roughness, proximity to physical barriers). The ecology and regeneration state of temperate, tropical and boreal forests under current climatic conditions are discussed, together with partitioning of photosynthetic and respiratory fluxes from soils and vegetation. The volume considers how to integrate contrasting methodologies, and the latest approaches for scaling from stand to the planetary boundary layer.

Book Description
Forty-two chapters by international experts from a wide range ofdisciplines make The Wetlands Handbook the essential toolfor those seeking comprehensive understanding of the subject. Adeparture from more traditional treatises, this text examinesfreshwater wetland ecosystem science from the fundamentals toissues of management and policy. Introductory chapters address the scope and significance ofwetlands globally for communities, culture and biodiversity.Subsequent sections deal with processes underpinning wetlandfunctioning, how wetlands work, their uses and values for humansand nature, their sensitivity to external impacts, and how they maybe restored. The text is illustrated by numerous examples,emphasising functional and holistic approaches to wetlandmanagement, including case studies on the wise use andrehabilitation of wetlands in farmed, urban, industrial and otherdamaged environments, highlighting the long-term benefits ofmultiple use. The Wetlands Handbook will provide aninvaluable reference for researchers, managers, policy-makers andstudents of wetland sciences.

Book Description
This book is an excellent resource for scientists, political decision makers, and students interested in the impact of peatlands on climate change and ecosystem function, containing a plethora of recent research results such as monitoring-sensing-modeling for carbon–water flux/storage, biodiversity and peatland management in tropical regions. It is estimated that more than 23 million hectares (62 %) of the total global tropical peatland area are located in Southeast Asia, in lowland or coastal areas of East Sumatra, Kalimantan, West Papua, Papua New Guinea, Brunei, Peninsular Malaysia, Sabah, Sarawak and Southeast Thailand. Tropical peatland has a vital carbon–water storage function and is host to a huge diversity of plant and animal species. Peatland ecosystems are extremely vulnerable to climate change and the impacts of human activities such as logging, drainage and conversion to agricultural land. In Southeast Asia, severe episodic droughts associated with the El Niño-Southern Oscillation, in combination with over-drainage, forest degradation, and land-use changes, have caused widespread peatland fires and microbial peat oxidation. Indonesia's 20 Mha peatland area is estimated to include about 45–55 GtC of carbon stocks. As a result of land use and development, Indonesia is the third largest emitter of greenhouse gases (2–3 Gtons carbon dioxide equivalent per year), 80 % of which is due to deforestation and peatland loss. Thus, tropical peatlands are key ecosystems in terms of the carbon–water cycle and climate change.

Book Description
This book provides an introduction to peatlands for the non-specialist student reader and for all those concerned about environmental protection, and is an essential guide to peatland history and heritage for scientists and enthusiasts. Peat is formed when vegetation partially decays in a waterlogged environment and occurs extensively throughout both temperate and tropical regions. Interest in peatlands is currently high due to the degradation of global peatlands which is disrupting hydrology and contributing to greenhouse gas emissions. This book opens by explaining how peat is formed, its properties and worldwide distribution, and defines related terms such as mires, wetlands, bogs and marshes. There is discussion of the ecology and wildlife of peatlands as well as their ability to preserve pollen and organic remains as environmental archives. It also addresses the history, heritage and cultural exploitation of peat, extending back to pre-Roman times, and the degradation of peatlands over the centuries, particularly as a source of fuel but more recently for commercial horticulture. Other chapters discuss the ecosystem services delivered by peatlands, and how their destruction is contributing to biodiversity loss, flooding or drought, and climate change. Finally, the many current peatland restoration projects around the world are highlighted. Overall the book provides a wide-ranging but concise overview of peatlands from both a natural and social science perspective, and will be invaluable for students of ecology, geography, environmental studies and history.

Book Description
During the last decades, soil organic carbon (SOC) attracted the attention of a much wider array of specialists beyond agriculture and soil science, as it was proven to be one of the most crucial components of the earth’s climate system, which has a great potential to be managed by humans. Soils as a carbon pool are one of the key factors in several Sustainable Development Goals, in particular Goal 15, “Protect, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification and halt and reverse land degradation and halt biodiversity loss” with the SOC stock being explicitly cited in Indicator 15.3.1. This technical manual is the first attempt to gather, in a standardized format, the existing data on the impacts of the main soil management practices on SOC content in a wide array of environments, including the advantages, drawbacks, and constraints. This manual presents different sustainable soil management (SSM) practices at different scales and in different contexts, supported by case studies that have been shown with quantitative data to have a positive effect on SOC stocks and successful experiences of SOC sequestration in practical field applications. Volume 2 includes a description of hot spots of SOC stocks. This manual defines hot spots of SOC as areas that represent a proportionally little of the global land surface but on which SOC storage is highly effective; bright spots as large land areas with low SOC stocks per km2 that represent a potential for further carbon sequestration.

Book Description
The Holocene spans the 11,500 years since the end of the last Ice Age and has been a period of major global environmental change. However the rate of change has accelerated during the last hundred years, due largely to human impacts and this has led to a growing concern for the future of our environmental resources. Global Change in the Holocene demonstrates how reconstructing the record of past environmental change can provide us with essential knowledge about how our environment works and presents the reader with an informed viewpoint from which to project realistic future scenarios. The book brings together key techniques that are widely used in Holocene research, such as radiocarbon dating, dendrochronology and sediment analysis and offers a comprehensive analysis of various archives of environmental change including instrumental and documentary records, corals, lake sediments, glaciers and ice cores. This reference will be an informative and cutting-edge resource for all researchers in the fields of climate change, environmental science, geography, palaeoecology and archaeology.
