Land & Ecosystems Accounts (LEAC)

• The SEEA methodological framework• 2 pilot project run by EEA & ETCTE (UAB & GISAT) with the support of Eurostat• Applications 1975-1990 for the European coast and 4 Central & Eastern Europe Countries, based on Corine land cover (CLC)

Framework of Land Accounts proposed by the UNECE task force, presented in Tokyo, 1996 …

CORE ACCOUNTS

Changes in Land cover/Land use

Biodiversity

Partitioning of land

Impacts of activities

Potentials of land

SUPPLEMENTARY ACCOUNTS, ISSUE ORIENTED

Sealing of soils

Artificiality

Productivity of land

LEAC present outcome

• Stratification of the territory into accounting units:Administrative unitsPhysical, ecological zonesDominant landscape types

• Definition and test of accounting methodology:Land cover stocksLand cover changes (from CLCy to CLCz)Land cover flows (which group changes into processes)

• 2 Reports and 2 Posters available at the Library of: http://eea.eionet.eu.int:8980/Public/irc/eionet-circle/leac/home

Land accounting units

• Grids

• Administrative Units

• River basins

• Sea catchments

• Bio-geographical regions

• Coastal units

• Dominant Landscape

Account of Land Cover Flows of the European Coast

COMMENT: Loss of ecosystems potentials generated by the use of land

26 types of land cover (green) are used for the formation of 10 types of new land cover (orange). At this level of aggregation, the only reverse flow is farmland abandonment.

(NB: only changes > 1000 ha are considered)

Next steps

• Tests of the use of the map of dominant landscape types in areas such as agri-environment indicators, ecosystems assessment, scenario making

• Production of land cover accounts with CLC2000• Analysis of trends of European territory in terms of

regional land cover flows• Further development of accounts by land use

functions (continuation of the case study on coastal tourism)

• Broad dissemination of data & maps on the EEA website
