This dissertation quantifies anthropogenic material stocks and population distribution and dynamics from Earth Observation data as a contribution to socio-economic metabolism research.
The socio-economic metabolism describes the input and output of the entirety of resources used to sustain a society and has become a key element of sustainable transformation research. Whereas many studies in socio-economic metabolism research study material and energy flows, the ERC-funded project MAT_STOCKS will focus on the long-term accumulation, distribution and depletion of material stocks. About half of all recent material flows could be allocated to stock accumulation, mainly in buildings and infrastructure.
This project builds on Earth Observation’s history of mapping anthropogenic land cover and land use. The study area is Germany. In a first step, dense satellite data time series is used to map physical characteristics of settlements – building presence, building height, the type of buildings and infrastructures. Chapter Two translates this information to high-resolution maps of population and to material stocks, the latter using material intensity factors that indicate the material density in tons per square or cubic meters of specific infrastructure or building features. In a third step, the project adds a historic dimension by using satellite data from 1984 onwards to estimate pathways of building and infrastructure developments in the study region.
This research receives funding from the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (MAT_STOCKS, grant agreement No 741950).
