This report was undertaken on local, regional, state and federal levels in the United States to analyse the impact residuals have on environmental quality and to emphasise the need for Residuals- Environmental quality management (REQM). Originally published in 1982, this study brings together information on approaches for analysing natural systems and which factors to consider when choosing an approach. This title will be of interest to students of environmental studies as well as professionals and policy makers.

Regional Analysis, Volume I: Economic Systems explores the interconnectedness of economic and social systems as they exist and develop in territorial-environmental systems. This volume concentrates on developing and refining models of trade and urban evolution, emphasizing evolutionary models and relationship between economic and political subsystems in the developmental process. Topics include the regional approach to economic systems; trade, markets, and urban centers in developing regions; spatio-economic organization in complex regional systems; and economic consequences of regional system organization. This publication is valuable to social and regional scientists, geographers, economists, social anthropologists, archeologists, sociologists, and political scientists interested in the implications of rural-urban relations and regional settlement patterns.
