"Provisioning ES examples";Problem;Solution
"Cultivated crops, reared animals, aquaculture";"High impact of external anthropogenic system inputs";"If possible, include indicators of human contributions and external environmental effects"
"Complex ES supply chains";"In absence of better data, use spatially explicit crop and stock statistics for mapping"
"Animal stables and aquafarms = locally discrete point SPA"
"Biomass-based energy sources";"E.g. maize, rape: final use not always clear";"Combination with respective ES demand"
Timber;"Temporal: long growth phases";"Distinction between ES potential and flow (Chapter 5.1)"
"Groundwater for drinking/ non-drinking purposes";"Subsurface SPAs; SBAs delocalised and point sources (wells, pipes)";"See Box 2 in this chapter"
