1. Accounting for ecosystem costs and benefits at different scales…
Amvrakikos, Greece:
Wetland management, Water & Fish
Global scale
Migratory Birds Flyways, Wetlands
& Bird Flu Prevention
Doñana, Spain:
Water, Wetland & Strawberries
National & regional government, European market
Action level, local scale

2. 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]
HANPP
Biodiversity rarefaction
Exergy loss [river basins]
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]

net Landscape Ecological Potential (nLEP) 2000, by 1km² grid cell
nLEP 2000 by NUTS 2/3
