Diffuse pollution is a global issue where management, particularly relating to phosphorus (P) transfers from agricultural land water, needs consider the magnitude of source pressure and connectivity hydrological pathway pressure. Combined, these pressures are considered as critical areas (CSAs) mitigation resources should be focused part landscape targeting. However, data requirements lack unified method have made this difficult implement at national scales. To overcome this, unique transferrable workflow presented for purpose three scales aid in prioritisation. First, macro- or basin-scale (100-600 km2) water quality (soluble reactive P-SRP) were used an initial indicator river basin scale Northern Ireland. Second, within macro-scale catchments, meso‑scale catchments (10-100 Water Framework Directive surveillance (n > 230) prioritised using validated relationship between long-term SRP soil test (STP-Olsen P) over 300,000 fields tested monitoring programme. These also screened persistent point ammonium (NH4) concentration data. Within each catchment, micro-scale (0.02 - 1.6 km2; 5th 95th percentile) identified (> 1.9 million) that combined summaries STP runoff risk metric was developed with high-resolution (16 points m-2) LiDAR derived topographic index (STI) into anonymised dimensionless Source:Pressure Priority Index (SPPI). Exemplar outputs shown detail weight equally, further emphasise pressure, vice versa, ensure advisory can allocated effectively. The SPPI more robust diffuse assessment management tool it recognises importance managing combination reducing pressures, rather than focusing on latter isolation. This will faster route reduction offer resilience mitigations become vulnerable weather patterns responses changing climate.
