FARMSCOPER (Farm Scale Optimisation of Pollutant Emission Reductions)

Farmscoper is a decision support tool that allows an assessment of the cost and effectiveness of agricultural mitigation methods on multiple pollutants. It incorporates meta-models of a number of different pollutant models which have previously been used for government policy support at national scale. Farmscoper was originally developed for use at farm scale, but the tool has now been expanded (v3) to include functionality to predict pollutant losses and mitigation impacts for multiple farms in order to simulate one or more catchments. It contains all the data required for use at Water Management Catchment scale in England.
