Different approaches can be used to describe land use change, occupation prevalence and their reciprocal inter-relation. In this paper we describe two different kinds of approaches: an agent based model, centred on individual choices and an aggregated model describing the evolution of activity prevalence in terms of coupled differential equation. We use and we compare the two models to analyse the effect of territorial constraints, like the lack of employment in determined sectors, on the possible activity prevalence scenarios.  aPopulation dynamics  aAgent based model  aDinâmica de populações  aImpacto de políticas  aModelo baseado em agentes  aMulti-funcionalidade  aMunicípios rurais1 aGARGIULO, F.1 aHUET, S.1 aDEFFUANT, G.
