"I highly recommend the landmark and important book Arid Zone Geomorphology: Process, Form and Change in Drylands by David S. G. Thomas, to any students, specialists in the field, policy makers, business leaders, and anyone interested in this critical and fascinating field. This book will guide both students and professionals in many disciplines and professionals toward a deeper and richer understanding of the importance of arid regions, and the processes at work in these amazing areas of our planet." (Blog Business World, 27 October 2011)
David S. G. Thomas is a scientist and geographer. He was born in Buckland Hospital, Dover, Kent, UK, in 1958. He is professor of geography at the University of Oxford, and a professorial fellow of Hertford College, Oxford.
