'A vital tool for policy-makers and scientists working on climate change mitigation.' Chris Goodall, author of the bestselling How to Live a Low-Carbon Life 'This book, I believe, provides the basic information required to allow implementation of the single most important initiative for humanity's environmental future. The biochar approach provides a uniquely powerful solution, for it allows us to address food security, the fuel crisis and the climate problem, and all in an immensely practical manner. With its careful evaluation of every aspect of biochar, this book represents a cornerstone of our future global sustainability.' From the Foreword by Tim Flannery 'This book provides comprehensive information and analysis on biochar technology and its implications. It is an essential reference in fostering pro-poor policies on energy efficiency and GHG mitigation based on land and soil improvements that could bring more justice into the climate change agenda.' Luc Gnacadja, Executive Secretary, United Nations Convention to Combat Desertification (UNCCD), Bonn, Germany 'Climate change seems an impossible problem. Impossible, that is, until one looks at the potential for biochar to permanently sequester atmospheric carbon. This wonderful volume is an invaluable handbook for those interested in the science and economics of soil amendment using biochar. A vital tool for policy-makers and scientists working on climate change mitigation.' Chris Goodall, author of the bestselling How to Live a Low-Carbon Life 'A detailed and comprehensive book... while some chapters may be more easily understood by soil scientists, chapters looking at the many advantages of biochar provide interesting reading to researchers and scientists in general.' LEISA 'A real eye-opener of a book that makes fascinating reading.' Bulletin of the British Ecological Society
