This book describes a decline in natural, biological productivity that is either irreversible or which may not be recovered for at least one human generation. The causes and forms of land degradation, as well as the means of managing and controlling it, form the subject of this book. Land degradation is not a new phenomenon. For at least 10 000 years, a principal activity of human culture has been to adjust and to modify the landscape in order to provide food, shelter, and warmth. Degradation probably began in earnest with the human control of fire, but the advances in technology and the relentless increase in human population of the past century have magnified both the degree of the problem and the area of the Earth that it affects. This book examines the history and current state of land degradation through an analysis of the linkages between natural and human systems and does so in a wide range of environmental, economic, and historical settings. The authors characterize land degradation as either unintentional and unforecast or intentional and creative, where zones have been deliberately sacrificed in order to achieve greater total productivity in the meeting of social needs. This distinction provides an important basis for analyzing the economic and cultural causes of degradation. To this the authors add the further dimension of degradation that takes place through processes that are themselves either wholly or partly natural. The failure to recognize the complex causes of land degradation is, they argue, on of the main reasons why it has been so difficult to control. The book is written in a nontechnical style making it readable by the general public.
Operational Control of Water Systems. Structure, Algorithms, andApplications. MA. Brdys and B. Ulanicki. Prentice Hall Inc., Englewood Cliffs, NJ; 1994. 364 pp. (ISBN 0-13-638974-O) hardcover. Availability of water and proper management of water resources are significant and increasingly important issues facing a large segment of the world. The ten chapters of this book address various aspects of simulation and modelling for prediction of demand, resources, and distribution of water supplies. Included are relevant case studies. Considering the significance of water, it is surprising that the number of books and compendia dedicated to this subject are limited. This book is recommended as a library reference and as a desk copy.

In the introduction of his book, the author states “in a never-ending struggle to survive, man must eat”. This comprehensive book provides a collection of data available on various pesticides particularly the monitoring data on pesticides in drinking water. The author discusses the difference between detecting a pesticide in water (a function of analytical competency) and the concentration of a pesticide. The emphasis is on data in the US both in terms of agricultural practices and pesticide concentrations in underground and other waters. The book discusses properties of an “ideal” pesticide and describes potential impediments for producing them. The book is rich in data. It is highly recommended as a desk copy and as a library reference.
Practical Management of Chemicals and Hazardous Wastes. An Environmental and Safety Professional’s Guide. W. Lee Kuhre. Prentice Hall PTR, Englewood Cliffs, NJ; 1995. 341 pp. (ISBN o-13-103946-6) hardcover. This book is intended as a guide for management of hazardous materials. The primary problem of the book is the lack of definition of hazardous material. The author uses the definition of the US Environmental Protection Agency (USEPA) for hazardous waste as a guide but can not escape the definition of the Occupational Safety and Health Administration for hazardous chemicals, the definition of the Department of Transportation for hazardous materials, or the definition of the USEPA for Superfund for hazardous materials. The problem is that each one of these covers a different set of criteria for defining the term “hazardous”. For example, the list of reportable quantities included at the end of the book includes radionuclides but the book does not address radiation and radioactivity. The section on transportation of hazardous materials is clear and is apparently the area of specialty of the author. The proliferation of regulations dealing with hazardous materials, the contradictory requirements of various laws, and the lack of science upon which many regulations are based are the causes of the problem. The author has done a credible job in describing the issue of dealing with hazardous materials.
Recreational Water Quality Management. Volume 2. Fresh Waters. David Kay and Roger Hanbury, eds. Prentice Hall, Inc., Englewood Cliffs, NJ; 1993; 245 pp. (ISBN 0- 13-767302-7) hardcover. This is the second volume of the compendium on water quality management. The first volume dealt with coastal waters and this second and final volume describes fresh
