Peatlands And Climate Change

The International Peat Society IPS established a joint IPS Working Group on Peatlands and Climate Change in the end of the year 2005. The Working Group's task was to compile information into a summary of available knowledge to help the IPS and other actors to understand the role of peatlands and peat within the current context of global climate change.

An interdisciplinary book tackling the challenges of managing peatlands and their ecosystem services in the face of climate change.

Peatlands in the Nordic Baltic region and elsewhere in the world store large amounts of carbon and are at the same time important for conservation of biodiversity. Thus peatlands are space-effective carbon stocks, but when drained carbon and nitrogen are released as greenhouse gases to the atmosphere and as nitrate to the surface water, while methane will be released when rewetting. New knowledge reveals that one of the most efficient means to mitigate emissions of greenhouse gases to the atmosphere are the restoration of drained peatlands by reestablish former high water tables on organic soils.This project on synergies between climate change mitigation and the restoration of peatlands has been conducted under a regional Ramsar initiative covering the Nordic and Baltic countries (NorBalWet), with support from the Nordic Council of Ministers. The report contains chapters on peatlands and their role in climate change mitigation, individual country chapters and the role of the Ramsar Convention.

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.

'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

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.
