      abstract = {The land-use optimisation framework, NZFARM, has been  promoted as a tool that can be used to assess the economic  and environmental impacts of policy on regional land use.  This paper outlines how methodological limitations  presently restrict its capacity to provide meaningful  insight into the relative value of alternative land-use  configurations. The model is calibrated using positive  mathematical programming, which has been shown in the  literature to result in models that yield arbitrary output  outside of the calibrated baseline. There is a high  likelihood that this is the case, as no validation appears  to have been carried out. Significant model development  will be required before NZFARM outputs can be used with any  confidence to inform future policy development. We conclude  with suggestions on how NZFARM and models of its kind can  be further developed to improve their capacity for  meaningful simulation.},
