Resulting maps for spatial explicit assessment of water purification (above) and provision of food and fodder (below). Maps of land use based assessment (a, step i), nitrogen retention potential and yield potential (b, step ii), and combined, spatial explicit assessment (c, step iii) for the current land use pattern (Business as usual, BAU). Values in (a) and (c) range between 0–100 points, (b) comprises classes 1 (high EP, pink), 2 (intermediate, green), and 3 (low, red).
