The Land Use in Rural New Zealand Model Version 1 (LURNZv1: Model Description)

This paper documents the first version of the Land Use in Rural New Zealand Model (LURNZv1). It describes the overall modelling approach, the database underlying the model, and the construction of each module within the model. The model is econometrically estimated from national time series data and spatially extrapolated using economic and geophysical variables. It is primarily a simulation model but is also set up to produce predictions based on future price scenarios. The model output includes projections of four types of rural land use under different scenarios and 25 ha grid maps of where land use, and changes in land use, are likely to occur.
