Fridolin Krausmann The metabolic transition The hypothesis of the metabolic transition is derived from historical evidence and claims that industrialization is related to fundamental and characteristic changes in the structure and size of social metabolism: –The transformation of the energy system: from solar based and land related (food, feed, wood) to fossil fuel based; from tapping flows to exploiting stocks –Changing relation of land use and energy: agriculture changes from an „energy source“ to a sink of energy –Absolute growth of population, material and energy use –Relative (per capita) growth of material and energy use –Characteristic metabolic profiles of agrarian and industrial socioecological regimes
