6 Spatial dynamic systems f ( I (t n ))... F F f ( I (t) )f ( I (t+2) )f ( I (t+1) ) Spatial dynamic systems simulates spatio-temporal processes in which the state of a location, on the Earth´s surface, changes over time, due to some physical phenomena.

10 Space-time modeling: issues for current methods Look at change over time at several localities Look at change across space for several moments in time

15 Space-time modeling: issues for current methods High resolution diachronic record in one or a few sitesunwarranted regional generalization across variable space High resolution spatial record for a few time periodspast as a sequence of snapshots with change happening invisibly between (or stepwise change) Conceptualizing rich socioecological variation across space and complex dynamics through time desirable but difficult with current methods

16 Future directions in space-time modeling Goals for study of long-term dynamics of human ecology High resolution models –spatial –chronological Link dynamically so that –state of modeled ecosystem at any given time (t) is in part a function of ecosystem at prior time (t-1) and affects future state (t+1) –State of modeled ecosystem at any given locale is in part a function of state in surrounding locales Test against archaeo-ecological record

17 Future directions in space-time modeling: an example Mediterranean Landscape Dynamics Project Project locations at opposite ends of Mediterranean Basin –Encompasses wide range of ecological & social variation –Tracks initial spread of agriculture & replacement of foraging systems –Different trajectories to the appearance of social complexity and urbanism
