  1. Analysis of the potential of the Ecological Footprint and related assessment tools for use in the EU’s Thematic Strategy on the Sustainable Use of Natural ResourcesTuesday, 3 June 2008DG Environment, Av. de Beaulieu 5 -1040 Brussels ENV Room BU-5 4/53 Land and Ecosystems Accounts (LEAC) & net Landscape Ecological Potential (nLEP) Jean-Louis Weber (EEA)

  2. The questions behind ecosystem accounting • Risks of unsustainable use of the living natural capital are ignored: the negative impacts of over-harvesting, force-feeding with fertilisers, intoxication, introduction of species, fragmentation by roads, or sealing of soil by urban development have no direct monetary counterpart. • The natural capital is not even amortised in accounting books of companies and in the national accounts – no allowance is made for maintaining ecosystems’ critical functions and services. The full cost of the domestic products is not covered in many cases by their price. • This is as well the case of the price of imported products made from degraded ecosystems: their full cost is not covered by their price. • Actual value for people of free ecosystem services is not accounted (the market tells: price is zero).

  3. Aggregates: integrated indicators valid at multiple scales This is not only a scientific, technical or data issue but a governance issue • Action scale: local communities, conservations agencies, companies, citizens – management, development, production, consumption, mitigation • Government scale: regions, countries (Unions of…) – framing and implementing policies, tradeoffs, monitoring • Global scale: global market and global ecosystem (atmosphere, oceans, biodiversity, river catchments…) – common objectives, conventions, monitoring, global mitigation • Some indicators are scale-specific, other indicators are valid at multiple scales: ecological potential, HANPP, virtual land, cost of maintenance and restoration of ecosystems net Landscape Ecological Potential (nLEP): a multi-scale indicator developed by the EEA from LEAC

  4. The making of nLEP Corine land cover (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

  5. 1990 2000 Change 1990-2000 Measuring change: LEAC/nLEP 1990-2000 • Change in Ecological Potential of SES Wetlands, ES,FR, IT, GR – 10 km strip

  6. nLEP at the local level: e.g. effect of land cover change
