'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

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.

The International Year of Planet Earth (IYPE) was established as a means of raising worldwide public and political awareness of the vast, though frequently under-used, potential the Earth Sciences possess for improving the quality of life of the peoples of the world and safeguarding Earth’s rich and diverse environments. The International Year project was jointly initiated in 2000 by the International Union of Geological Sciences (IUGS) and the Earth Science Division of the United Nations Educational, Scienti?c and Cultural Organisation (UNESCO). IUGS, which is a Non-Governmental Organisation, and UNESCO, an Inter-Governmental Organisation, already shared a long record of productive cooperation in the na- ral sciences and their application to societal problems, including the International Geoscience Programme (IGCP) now in its fourth decade. With its main goals of raising public awareness of, and enhancing research in the Earth sciences on a global scale in both the developed and less-developed countries of the world, two operational programmes were demanded. In 2002 and 2003, the Series Editors together with Dr. Ted Nield and Dr. Henk Schalke (all four being core members of the Management Team at that time) drew up outlines of a Science and an Outreach Programme. In 2005, following the UN proclamation of 2008 as the United Nations International Year of Planet Earth, the “Year” grew into a triennium (2007–2009).

Peatlands have so far been identified in 180 countries and they occur extensively in both the northern and tropical zones of our planet. They usually form in depressions where water permanently accumulates, either sustained by rainwater or underground sources. A lack of oxygen in the waterlogged environment slows decomposition of organic matter, leading to the accumulation of peat layers. However, across the globe peatlands are under threat from drainage and burning for agricultural, forestry and development uses. Fifteen percent of reserves are currently understood to be either destroyed or degraded. To help achieve these outcomes, this report assesses the extent of peatlands in the tropics, the threats they face and the action being taken to preserve them. 1. Peatlands are important to human societies around the world. They contribute significantly to climate change mitigation and adaptation through carbon sequestration and storage, biodiversity conservation, water regime and quality regulation, and the provision of other ecosystem services that support livelihoods. 2. Immediate action is required to prevent further peatland degradation and the serious environmental, economic and social repercussions it entails. Existing options to tackle the issue vary, and for that reason implementation should be regionally adapted to local environmental, economic and social needs and characteristics. 3. A landscape approach is vital and good practices in peatland management and restoration must be shared and implemented across all peatland landscapes to save these threatened ecosystems and their services to people. 4. Local communities should receive support to sustainably manage their peatlands by preserving traditional non-destructive uses and introducing innovative management alternatives. 5. A comprehensive mapping of peatlands worldwide is essential to better understanding their extent and status, and to enable us to safeguard them. Research and monitoring should be improved to provide better maps and tools for rapid assessment and transparent use of them to underpin action and multi-stakeholder engagement.

This book examines relationships between climate-hydrological changes and other phenomena including land use and natural disasters during the Holocene and recent past. In particular, periods of rapid climatic shifts such as global warming and global cooling are examined through paleohydrological and other studies of various lake-catchment systems in East Asia, from Mongolia in the north to Taiwan in the south. A number of different research techniques are used in the work presented here, including sediment analysis and optically stimulated luminescence dating and the reader learns how the lake-catchment system functions as a “proxy observatory” for past and present environmental monitoring. The lake catchments studied by the authors of this volume are under similar climatic conditions, i.e., under the East Asia monsoon, with some systematic difference in climatic factors. Both proxy and observation data are available for the surrounding countries’ provisions against natural disasters that are related to climate-hydrological events and readers will see how present instrumental observation data can be connected to past proxy data (sediment information) in the system.

Much of the upland and marginal landscapes of Wales are characterised by an abundance of abandoned houses and farmsteads. These remains are the tangible evidence that for many hundreds of years successive communities occupied and exploited rural areas that are now largely depopulated. This book presents evidence from a detailed field study project into the deserted rural settlements throughout Wales - exploring settlement morphology, monastic upland exploration, medieval and post-medieval settlement development and change, vernacular building traditions and environmental evidence. The volume establishes what is known about these settlements, their regional variations and national characteristics, and what future research could still uncover.
