Geographical, Environmental and Behavioural model (GEB)

GEB, the Geographic Environmental and Behavioural model, is a coupled agent-based and hydrological model which can simulate millions of individual farmers and their bi-directional interaction with a fully distributed hydrological model on a powerful laptop. The model is jointly developed by IVM and IIASA. It is named after Geb, the personification of Earth in Egyptian mythology. You can find full documentation here.

The model is build using widely used hydrological model CWatM and the agent-based model Honeybees for high-performance ABMs in Python. Some of the behavioral components of the model are based on ADOPT .
