| Zusammenfassung |
| We present a simple, adaptation-driven, spatially explicit model of pre-Bronze age
socio-technological change, called the Global Land Use and Technological Evolution
Simulator (GLUES). The socio-technological realm is described by three characteristic traits:
available technology, subsistence style ratio, and economic diversity. Human population and
culture develop in the context of global paleoclimate and regional paleoclimate events. Global
paleoclimate is derived from CLIMBER-2 Earth System Model anomalies superimposed on
the IIASA temperature and precipitation database. Regional a forcing is provided by abrupt
climate deteriorations from a compilation of 138 long-term high-resolution climate proxy
time series from mostly terrestrial and near-shore archives. The GLUES simulator provides
for a novel way to explore the interplay between climate, climate change, and cultural
evolution both on the Holocene timescale as well as for short-term extreme event periods.
We sucessfully simulate the migration of people and the diffusion of Neolithic
technology from the Near East into Europe in the period 12000–4000 a BP. We find good
agreement with recent archeological compilations of Western Eurasian Neolithic
sites. No causal relationship between climate events and cultural evolution could be
identified, but the speed of cultural development is found to be modulated by the
frequency of climate events. From the demographic evolution and regional ressource
consumption, we estimate regional land use change and prehistoric greenhouse gas
emissions. |
