This map annex forms part of the final output of NRA R and D Project on the sources and impacts of farm pollution. It is intended for use in conjunction with the associated Project Record. Full details of the derivation of the maps in this annex can be found in the Project Record. By way of summary, all maps are outputs from an ARC INFO GIS linked database of farm pollution risk, developed under the project. This is an interactive system that can be interrogated for information on a range of factors relating to pollution risk. The catchment framework shown in Map one was digitised from hydrometric maps supplied by NRA Regions and, where these were not available, quinquennial river quality maps. All catchments have been codified and linked to catchment names, see Table 1. Livestock and land use data were obtained from the 1988 Agricultural Censuses of England and Wales, Scotland and Northern Ireland. Pollution incident data were derived from NRA regional archives, data for 1988,a wet year, and 1989, a dry year, were collated and incorporated into the pollution risk database, but only 1988 data are displayed in this map annex. Table two gives details of the pollution incident types and severity codings used.
