DESCRIPTION:The land system is a complex system. It depends on a miriad of
  interactions between individual\, heterogenous land users\, on the variab
 ility of the physical environment (soils\, climate\, &hellip\;) and on the
  diversity of societal structures including communities\, institutions and
  public policy organisations. Many modelling approaches have been proposed
  to represent land systems\, with the dominant paradigm based on economic 
 optimisation. However\, assuming that individual land managers make decisi
 ons about land use based on economic rational alone is a serious simplicat
 ion of the complex land system. In practice\, we know that individuals mak
 e land use decisions based on many\, often conflicting factors such as ris
 k aversion\, social standing\, tradition and environmental impact within t
 he context of having imperfect access to knowledge. And that many of these
  processes play out at different spatial scale levels. In this presentatio
 n I will explore how different approaches to modelling land systems can be
  coupled across scales in order to capture the salient processes at each s
 cale level. This includes modelling of land-based commodity trade-flows at
  the global scale\, sub-national agent-based modelling of land use decisio
 n making\, and the representation of public policy organisations that infl
 uence land users locally.
