Farmscoper is a decision-support tool to assess diffuse agricultural pollutant loads on a farm

It can also quantify the impacts of farm mitigation methods on these pollutants. The farm systems within the tool can be customised to reflect management and environmental conditions representative of farming across England and Wales. The tool contains more than 100 mitigation methods, including many of those in the Defra Mitigation Method User Guide.

Farmscoper was originally developed under Defra project WQ0106. Under Defra Project SCF0104, it was expanded to include additional pollutants and two new workbooks. One workbook provides greater detail on the costs of mitigation method implementation. The other permits the tool to be applied at catchment to a national scale.

New updates in the latest version

Under Environment Agency and Defra funding, the latest version (v5) now includes up-to-date climate, agricultural survey and farm management data.

The updated greenhouse gas (GHG) calculations closely match the latest UK Agricultural Ammonia and GHG inventory.

The installation package includes new documentation on applying Farmscoper at smaller spatial scales.
