This work is intended for advanced readers interested in methods of sustainable land management - the prevention and control of land degradation. It offers a coherent view of the situation concerning land degradation and the human response to the problem. It is generally recognized that technological solutions alone cannot solve the problems of land degradation. This book discusses the role of land use and land management policies, programmes, insitutional innovations, and economic incentives for the control and prevention of land degradation. Special attention is given to legal issues at the international level and in individual countries.

World Geomorphology deals with the large scale relief features of the earth and shows how these are related to the major segments of the earth's crust known as lithospheric plates. The aim of the book is to convey an understanding of the earth's major relief features and to present a subdivision of the earth's surface in provinces which have had similar geological or geomorphological history. The book starts by presenting the reader with the basic geological column and the means of subdividing the landscape into areas with a common origin and developmental history, and gives an explanation of the basic principles of plate tectonics. The continental and oceanic areas of each lithospheric plate are then described: successive chapters deal with the African Plate, American plate, Antarctic plate, Asian plate, the European plate and the Pacific plate, indicating the regional geomorphological features after a brief geological introduction. This encyclopedic volume will provide a valuable reference for students of geology and geography.
