ABSTRACT
Geospatial modeling and mapping of environmental displacement and migration is a relatively new application area. This entry examines mapping efforts that identify potential drivers of migration and broader vulnerability patterns, which can help to identify areas where migration may be one outcome of environmental or climatic stress. It then goes on to consider incipient work in spatial modeling of environmental displacement and migration. Our review summarizes two main approaches to modeling, gravity modeling and agent based modeling. We identify the strengths and weaknesses associated with these approaches, and highlight possible refinements and future opportunities, emphasizing the importance of empirical work to advance understanding of the causal mechanisms linking migration flows to environmental status and change, and to understand geographical trajectories.
