Methodology to approve for IPPC use a national estimate of N loss by leaching and runoff from UK agricultural land - CC0231

This project will aim to develop a geographical representation of the location of agricultural and other land uses, by drawing together a range of data sources. The study will be composed of 4 specific objectives outlined as follows, together with ways in which they might be achieved: 1. Identification of available primary and secondary data sources and their extents, completeness, costs and licensing arrangements. Primary data sources will include the DTER Urban Land Use map, the Digitised Map of Common Land and the extents of forests where possible. Secondary data sources will include maps of major roads and the locations of airfields; 2. Integration of data into the GIS of England and Wales at 1 km resolution. The data will be used to generate estimates of land area covered by urban land, common land etc. For line and point data it will be necessary to estimate the area involved, such as assuming the standard area for a golf course and the standard width for a particular road class; 3. Calibration and validation of the dataset. The accuracy of the dataset, and the improvement it is expected to provide, will be tested using ground truth data from large Nitrate Sensitive Areas, several of which have been mapped accurately; 4. Provision of final dataset and report. The final dataset will be available as estimates of agricultural land area per km square. The data will be made available for integration into MAFF’s nitrate policy support model (ADAS MAGPIE-N), and for use in conjunction with Landcover 2000. This spatial data will aid interpretation of satellite imagery and thereby provide greater accuracy in modelling agri-environmental interactions within catchments or other defined areas.
