An e-science approach allows the integration of different data types to develop coherent analyses of past and expected impacts of natural and human caused environmental change and the corresponding impact on human population structures. Demographic analyses have been possible for some time both with and without the aid of computational tools, however, the implementation of e-science tools allow a more dynamic manipulation of scenarios drawing on actual social, economic and demographic data and correlating that with GIS spatial data. The resulting implementation allows us to generate 'snapshots' in time to reconstruct the impact of past events or hypothetical events. In this way, we can test the feasibility of data extraction from diverse data sources produced for different research programs in different disciplines. The research is driven not by an interest in technological development, but rather as one part of a general strategy designed to inform policy decisions in a situation with a number of methodological and practical constraints
