Economic plants have been defined by SEPASAT as those plants that are utilised either directly or indirectly for the benefit of Man. Indirect usage includes the needs of Man's livestock and the maintenance of the environment; the benefits may be domestic, commercial or aesthetic. Economic plants constitute a large and so far uncalculated percentage of the quarter of a million higher plants in the World today. However, it has been calculated that 10% (25 000) of these species are now on the verge of extinction and extinction means that a genetic resource that could be of benefit to Man will be lost for ever. Furthermore, for every species lost an estimated 10-30 other dependent organisms are also doomed. Fewer than 1 per cent of the World's plants have been sufficiently well studied for a true evaluation of the potential floral wealth awaiting discovery, not only in the rain forests, which man is now actively destroying at a rate of 20 ha a minute, but also in the very much neglected dry areas of the World.

With increasing awareness of the limits that natural resource reserves and environmental concerns impose on economic growth, rural sociologists have developed new ways of looking at the relationship between man and his environment. This volume surveys changing sociological views of that relationship and explores a holistic, cooperative model of human/nature interaction that reflects the needs of the post-industrial age. In their introduction Field and Burch review significant landmarks in natural resource sociology and comment on some of the underlying aims of rural sociology. The remaining chapters focus on three distinct periods during which rural sociologists have sought to examine man's relationship and adaptation to the environment.

Rural Sociology and the Environment traces the origin and development of the sociology of natural resources practiced by Rural Sociologists since the turn of the century. The 135 page book is a recognition of the interplay of environment and human behavior as a basis for understanding of rural life, its problems and opportunities. An ecological perspective which permeates Rural Sociology is described and a contemporary ecological framework for examining natural resource issues of the day is introduced. An exhaustive and user friendly bibliography accompanies each chapter.

Rural Sociology and the Environment clearly and carefully illustrates the evolution of natural resource sociology and social science as a distinct field of study. Well before "social-ecological systems" became a popular concept in academic literature broadly, Donald R. Field and William R. Burch, Jr. co-authored this seminal text on what they call "social ecology." In this examination, these authors explore the evolving concepts of the environment in Rural Sociology during the 20th century from "dominion over nature" to "expanding the domain of nature" to "nature as a partner," which reflects a broader recognition of human dependence on environmental systems. One important contribution of this text is the revelation that the contemporary recognition of environmental service values for people emerges in part from a rigorous tradition of scholarship in Rural Sociology.

People, Places and Landscapes: Social Change in High Amenity Rural Areas (Landscape Series, 14)

This volume is a cogent empirical analysis of the interplay between a region’s natural amenities and its socioeconomic  evolution. It focuses on the rural sectors of America’s Intermountain West region, which lies between the Cascades and Sierra Nevada mountains to the west and the Rocky Mountains to the east. Coherently structured and meticulously detailed, it adds much to our understanding of the ways an area’s forests, lakes, mountains, parkland and historic attractions affect residents’ sense of well-being as well as the sociodemographic and economic changes they experience. The book examines patterns of growth and change linked to the emergence of ‘New West’ conditions, assessing their implications for the wider community as well as discussing the impact these trends could have on the consumption of natural resources. It also points to ways in which communities and their development can be managed sustainably. The tight geographical focus of this valuable resource ensures a depth of analysis which can be applied to similar regions worldwide. Based on a large-scale, random-sample survey of both full-time and seasonal residents, it provides a much-needed overview of the macro-level economic, demographic, and social transformations affecting rural communities in America. As such, the book has relevance for all researchers concerned with rural development, the changes impacting rural landscapes, and natural resource management.
