Metabolism and colonization. Modes of production and the physical exchange between societies and nature

Written by a sociologist and a biologist, this paper attempts an interdisciplinary approach to describing the basic exchange relations between human societies and their natural environments. One type of exchange relation is termed ‘metabolism’ and related to the biological metabolism member organisms of societies require. A historical overview (part 1) demonstrates this exchange relation in terms of mass throughput per inhabitant to have grown in the course of human cultural evolution—without necessarily increasing the quality of life of those concerned—to the twentyfold it now amounts to in industrial societies (as is demonstrated empirically for Austria in part 3). A strategy of ‘contraction of physical metabolism’ (reduction of physical growth irrespective of ‘economic’ growth) of industrial societies is proposed as a strategic means of survival and possible ways to this goal are discussed quantitatively. The other exchange relation termed ‘colonization’ refers to treatments of natural environments that purposively change some components to render better exploitability (for the purpose of social metabolism), while still relying upon their basic self‐regenerating qualities. It is sketched how colonization strategies developed historically, and it is demonstrated empirically that industrial societies now use about 50% of the available plant biomass (the energetic basis of all animal life) upon their territories for human purposes (part 4). Part 5 classifies different ‘paradigms’ for judging the ‘harmfulness’ of social interventions into the environment and outlines the logic of an information system that would enable society to generate an awareness of its own interventions into nature. On the whole the paper presents a theoretical as well as an empirical attempt to view societies as physical systems (among other physical systems on this planet) and confront sociology with the paradigmatic task to analyze the social regulation of these physical processes.
