Global Environmental Change and Historical Transitions

What do transition processes in rural areas in Thailand, biomass consumption in nineteenth-century Austria and the ecology of hunter-gatherers have to do with the appropriation of plant production and global environmental change? More than one might think of in the first place. They are part of a scholarly discourse on our changing relations with the environment. We argue that global change can be analysed in terms of transitions between major modes of subsistence and try to document this with several case studies.

Beyond IPAT and Kuznets Curves: Globalization as a Vital Factor in Analysing the Environmental Impact of Socio-Economic Metabolism

We bring the rapidly developing tools for analyzing society's metabolism to the attention of a scientific audience concerned with matters of population and, in a complementary fashion, we draw the attention of material and energy flow analysts to the role of population and population dynamics within their own paradigm. As an analytic framework, we use the classic IPAT-model that relates environmental impact (I), population (P), affluence (A), and technology (T). We relate the IPAT model to the tool commonly used in MFA, so-called environmental Kuznets curves, and re-analyze empirical data from various sources, for both affluent industrial and for developing countries, within these frameworks. We conclude that population and technology seem to dominate over affluence as far as environmental impact is concerned, but that both the IPAT and Kuznets models fail to take into account the intricate interdependencies among different socio-economic systems and the increases in their the economic, material and population exchanges. In effect, both models tend to underestimate the environmental impact and create too optimistic an image of dematerialization in affluent industrial countries.
