Integrated assessment of the environmental, economic and social impacts of land use change using a GIS format – the CLUES model AgEcon

The CLUES model is an integrated catchment based model that designed to assist policy makers in understanding the implications of land use scenarios for water quality and a range of other indicators. CLUES integrates a number of existing models from several research providers, including SPARROW (catchment hydrology), OVERSEER and SPASMO (nutrient losses), ENSUS (nitrate leaching risk), and a socioeconomic model. These are combined in a GIS framework which allows scenarios of land use to be assessed in a spatial manner. Regional council staff have been trained in its use, and the model is under ongoing development in response to feedback from users. This paper discusses the overall framework of the CLUES model, and discusses in greater depth the...

Specification of Environmental Emission Trading Options in a Spatial Multi-Agent Simulation Model of Pastoral Farming AgEcon
Dake, Chris K.G.; Manderson, Andrew K.; MacKay, Alec D..
A risk efficient frontier for a pastoral farm indicates the optimal enterprise mix that allows the farmer to generate the highest income for a given level of financial risk. It is calculated by matching the available range of enterprises (sheep, beef cattle, deer, dairy, exotic forest and indigenous forest) to the mix of land classes available on the farm. The quantity of environmental emissions produced from the farm varies with the optimal enterprise mix along the risk efficient frontier, and therefore enables the farmer to assess the financial consequences of moving along the frontier to achieve a desired level of environmental emissions. This study uses databases of land cover, land classes and farm boundaries to develop a method for estimating the...
