CLUES – Catchment Land Use for Environmental Sustainability model

CLUES is a GIS based modelling system that assesses the effects of land use change on catchment-scale water quality (mean annual loads of TN, TP, E. coli and sediment) and socio-economic indicators. It was developed by NIWA for MAF (now MPI) and is an amalgamation of existing modelling and mapping procedures contributed by various research organisations, including MfE, AgResearch, Landcare Research, Plant and Food Research and Harris Consulting.

CLUES allows users to create both land use and farm practice change scenarios (stocking rates, intensification/mitigation) using a range of tools. The model has also been coupled to an estuary model to estimate potential nutrient concentrations.  Results are available in map and tabular displays. CLUES software and the user manual are publicly available for download from our FTP site (link below).

NIWA has experience in a wide range of CLUES applications and can also provide training.
