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

  2. 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] Simplified ecosystem accounts

  3. Example of a first candidate: LEP Corine land cover map (derived from satellite images)‏ Green Background Landscape Index (derived from CLC)‏ Naturilis (derived from Natura2000 & CDDA)‏ Effective Mesh Size (MEFF, derived from TeleAtlas and CLC)‏ net Landscape Ecological Potential (nLEP) 2000, by 1km² grid cell nLEP 2000 by NUTS 2/3

  4. LEP, state and change by 1 km2 grid Natural Park of Camargue (France)‏ 1990 Change 1990-2000 LEAC/ Landscape Ecological Potential1990-2000, 1km² grid (Source: Ecosystem Accounting for Mediterranean Wetlands, an EEA feasibility study for TEEB)‏
