Current research on environmental decision-makers at the professional and nonprofessional levels is reviewed. The potential utility of this research for achieving more adaptive man-environment relations in modern industrial societies is examined. A broader framework of research is suggested for viewing the antecedents and consequences of environmental decision-making from an ecological perspective. Mechanisms for promoting research on man-environment relations are considered. In particular, issues in the training of scientific man-power in this interdisciplinary fieM are discussed.An increasingly concerted and interdisciplinary effort over the past decade or so has sought to advance our understanding of man-environment relations within the context of modern industrial society. This endeavor obviously possesses intrinsic value and fascination but it also offers some promise of promoting more enlightened policies and practices within such fields as architecture, urban planning, transportation engineering, conservation, natural resources management, and environmental education.The adjustment of a society to its physical environment is a dynamic process that represents the cumulative and interactive effect of multifarious decisions by its individual members. It is commonly asserted that in pre-industrial societies environmental decision-making, concerning the design of structures (Alexander, 1964) and the management of natural resources (Kates,
