The development of an integrative modelling framework to analyze and simulate the spatial and temporal dynamics of transformation, adaptation and reorganization processes in human-nature environments of prehistoric and archaic societies constitutes the main focus of project A2. Based on the data and expert knowledge gained conceptual and computerized models will be set up  in order to simulate the spatio-temporal patterns of development and transformation processes in human-organized landscapes in Europe and the Mediterranean.

Research activities

In the first years of the CRC 1266 we developed different open-source packages for the statistical computing language R (Fig. 1).

Pakete der ModellierungssuiteFig. 1. Packages of the modeling suite.

In combination these packages form a modeling suite that can be applied to various contexts, in particular the identification and investigation of transformation processes (Fig. 2).

The theoretical reflection on our research agenda lead us to an understanding of models as heuristic devices. They complement data and narratives from the different disciplines involved in the CRC (cooperation with A1; Fig. 3).

The model suite allows to test different scenarios of interaction between societies and environment (cooperation with D1; Dal Corso et al. 2019; Fig. 4).

First results of applications of the model suite showed that transformations take place on different social, spatial, and temporal scales (cooperation with C1; Knitter et al. 2019).

Besides this, we could also show (Knitter et al., accepted) that transformation drivers like innovation that coincide with environmental changes (independent whether these occur as triggers or reactions) can be traced using our models and fit to other proxies (Fig. 6). However, the space, where these changes occur was not limiting and hence subsequent dynamics should not be reduced to environmental limitations or natural determining factors (Fig. 7).
