This book synthesizes knowledge from several fields that are crucial to sustainable rural development: the physical environment, biological and agricultural production, rural sociology and economics. It takes a systems perspective incorporating systems analysis, landscape analysis and soil, water, and land planning. Rural Planning from an Environmental Systems Perspective is directed toward graduate students and professionals, providing a source of information and concepts for those concerned with land and water policies and practice. It presents an integrated approach using practical and applicable models and methods and takes a middle position between an elementary conceptual approach to land and water management and a highly mathematically advanced treatise based exclusively on system modeling. The book is based on almost twenty years of experience in teaching a course on rural planning and the environment at the International Centre for Advanced Mediterranean Agronomic Studies in Zaragoza, Spain. The authors are specialists from universities, research institutions and companies in Europe and North America.

The ability of small mammals to exploit environmental resources, based upon a rapid adaptation to short-term changes in population and/or the environment, as well as to a variety of local conditions, implies a strong impact upon natural resources. The role played by small mammal consumers in the flow of energy within natural and man-modified ecosystems is therefore of equal importance to that of larger, longer-lived species which have been studied more intensively. This volume, first published in 1975, looks at small mammal populations with emphasis being placed on their ecology and energy dynamics. It discusses the most productive research techniques and research objectives. The second part of the book deals with the roles of small mammals in ecosystems ranging from the tropics to the tundra and special consideration is given to the impact of rodents on man. Research workers in the fields of mammalogy and ecology will find this an essential book and agriculturists, foresters and anyone concerned professionally with the control of small mammals will find much that is of value to their work.
