Biodiversity, resilience and the control of ecological-economic systems: the case of fire-driven rangelands

Case
This case explores semi-arid rangelands which may exist in varying degrees as grassland and woodlands.  Depending partly on the soil conditions, more sandy favoring woodlands and more clay favoring grasslands, as well as the behavior of fire and herbivores, an optimally controlled management of this environment looks at the interaction of these elements. In particular, the time horizon of the management planning can heavily influence paths and conditions of the system.

Ecological-economic model for optimal control of fire-driven, semi-arid rangelands

Model
This is an ecological-economic model that endogenizes discontinuous change between states of fire-driven, semi-arid rangelands which may exist in varying degrees as grassland and woodlands depending partly on the given soil conditions. More sandy soils will result in woodlands, whereas clay soils will more likely result in grasslands. One of the critical features of this model is the existence and impact of fires on these different types of rangelands. Grasslands may build up biomass and create...
