Accounting for ecosystem costs and benefits at different scales…

Global scale

National & regional government, European market

Action level, local scale

Migratory Birds Flyways, Wetlands & Bird Flu PreventionDoñana, Spain: Water, Wetland & StrawberriesAmvrakikos, Greece: Wetland management, Water & Fish

Simplified ecosystem accounts

Markets need accounts, regulations [= control]

Land ecosystems are spatially distributed => grid data [e.g. 1 km2]

Globally, change matters [degradation or improvement of ecosystem functioning and attached cost], not the value of the stock

Global multicriteria rating based on a small number of ecological potential [derived from ecosystem accounts]:

Landscape ecological potential [LEP]Landscape ecological potential [LEP] HANPPHANPP Biodiversity rarefactionBiodiversity rarefaction Exergy loss [river basins]Exergy loss [river basins] Dependance from external inputs [material/energy, footprint]Dependance from external inputs [material/energy, footprint]

losses/gains of “points of ecological potential” computation of restoration costs [needed for compensating losses // or accumulated by gains of points]

Rating can be detailed as necessary for the policy [national, regional] and action scales [local, business]
