Soil Carbon and Greenhouse Gas Dynamics in European Ecosystems is a comprehensive overview of the latest research in this field drawn together by a network of scientists, currently working for the European research programme, COST Action 639 BurnOut(www.cost639.net; 2006-2010). COST Action 639 emerged from a demand from policy makers in Europe for more detailed information on soil carbon dynamics. The cooperation between experts for reporting and experts for soil dynamics is the focus of the book. This book seeks to provide an up-to-date account on the state-of-the-art research within this topical field. This book focuses primarily on ecosystems and their soil carbon stocks. The book identifies three key sensitive ecosystems within Europe: Mediterranean Forest and Agricultural Systems; Mountains; and Peatland.
