1 27-28 April 2005Geoland workshop GEOLAND workshop Medium resolution change detection 27-28 April 2005, JRC, Ispra EEA’s requirements for European assessments of the Environment Jean-Louis Weber Spatial Analysis Group European Environment Agency

2 27-28 April 2005Geoland workshop EEA in the GMES “diamond” as in COM(2004) 65 final EIONET REPORTNET Assessments Data service European User Information system, GIS, Environmental Accounts Scenarios

3 27-28 April 2005Geoland workshop Main policy focus  6th EAP & most thematic strategies  Water framework directive: river basin management, ecological monitoring  Natura 2000: pressure by land use, connectivity…  Biodiversity: ecosystem based approach  Land planning: ESDP/ESPON, ICZM, Urban strategy, Regional policies, transport  Agriculture-environment  Sustainable development: Natural Capital issue  Access to European pertinent environmental information by all levels of governance and citizens  Focus on priorities: “risk based data collection”

4 27-28 April 2005Geoland workshop Integrated spatial assessment at the EEA 1. Land use systems: urban, agriculture, forestry, transport… 2. Ecosystems: wetlands, dry grasslands, forests, agro-ecosystems, water ecosystems… 3. Water systems (water bodies): groundwater, rivers, lakes, coastal water… 4. Landscapes where 1, 2, 3 interact: landscape types, ecological corridors…  Data assimilation with  GIS (CLC, WISE, INSPIRE…)  Environmental accounting (physical & monetary)  Stratification(s) of site monitoring data  Data modelling

5 27-28 April 2005Geoland workshop Platform for Integrated Spatial Assessment of Land, Biodiversity & Water, based on Corine Land Cover

6 27-28 April 2005Geoland workshop Environmental Accounts for Integrating Environmental, Economic & Social Data and Assessing Sustainable development Natural Capital Accounts Production, Consumption Income & Capital Accounts Social Accounting Matrixes Depletion, Degradation & Formation of Natural Capital Distribution of Income & Consumption Patterns Ownership of Natural Assets Use of Free Goods & Services

7 27-28 April 2005Geoland workshop Natura 2000 sites Landscape Natural Potential Legend Ecological corridors are fragmented by roads, railways, dams, and urban sprawl, which partition Natura2000 sites from other sites and ecosystems. In addition to losses of habitats, species trend to be isolated and therefore endangered. Total urban sprawl Roads Source: EEA/Corine land cover 1990-2000/ Land Accounts Project Provisional results Spatial integration of data on land cover & Natura 2000 Urban sprawl over semi-natural land

8 27-28 April 2005Geoland workshop Integration in SEEA’s Land & Ecosystem Accounts CORE LAND COVER ACCOUNT ECOSYSTEM ACCOUNTS Soil Flora & Fauna Water system Atmosphere/ Climate Ecosystem services Ecosystem potentials Integrity, health & viability Vulnerability LAND USE ACCOUNTS Land use economic & social functions Artificiality of land Intensity of use Production & Consumption Natural Assets Population Infrastructures & Technologies

9 27-28 April 2005Geoland workshop Land cover account, Comunidad de Madrid, 1990-2000 Source: Corine land cover 1990-2000  Land COVER accounts are implemented at the EEA from CLC2000 Land and ecosystem accounts…  …measure stocks as well as change due to gains and losses (flows)  …are made of Land Cover Accounts Land Use Accounts Ecosystem Accounts  …are part of the UN system of environmental & economic accounting

10 27-28 April 2005Geoland workshop Land use accounts & functions Spatial monitoring + Socio-eco statistics Urban Natural Rural

12 27-28 April 2005Geoland workshop Individual v.s. geo-statistical monitoring/ accounting WETLANDS 1990 OF N-W EUROPE EEA/ETCTE (courtesy Danube Delta National Institute)

13 27-28 April 2005Geoland workshop Stratification issue: “natural length scales” Space/time dynamics of a system Noise vs. signal, monitoring of trends Improved correlations  Space oCLC & CLC change as a spatial infrastructure oOther geographical infrastructure: rivers, catchments, NUTS/LAU, transport, soil… (INSPIRE) oLandscape modelling oTargeted land cover mapping large scale): cities, protected areas…  Time oTime cycles: 1 day, 10 days, 1 month, 1 season, 1 year, 3 years, 10 years, 30 years… oShort cycles matter: meteorology, soil humidity, phenology…

14 27-28 April 2005Geoland workshop Spatial stratification and modelling (e.g., N surplus calculation vs. strata) DF, national criteria and thresholds Stratification (with Agri.Stats, CLC & Population) N surplus calculation (based on Agri-stats, CLC and Ifen /EEA model)

15 27-28 April 2005Geoland workshop Time stratification: e.g. water resource/demand Mean annual values may tell the same stories (i.e. no water shortage in the river)… … for very different conditions. Variability matters…

18 27-28 April 2005Geoland workshop EEA’s expectations to space monitoring for European assessments 1. Secure the continuation of Corine land cover (the backbone of the system)  High resolution, medium infrared, free access pre-processed data, EU full coverage 5 years 2. Supply assessment of texture/ structure elements: oParcel borders and small linear features: same as 1, enhanced panchromatic oVegetation structure of forests & open landscape: medium resolution, multi-angle imaging 3. Permanent monitoring of: oVegetation, phenological cycles oPrimary & ecosystem productivity oWater in soil, irrigation oTemporary humidity, wetlands oConversions pasture-arable land oFloods, storms, forest fires  Medium resolution (300m), medium infrared, 10 days synthesis 4. Monitoring of main land cover change between 2 CLCs oAggregated land cover accounts, not the full CLC resolution (tests with GLOBCOVER2005)  Medium resolution (300m), EU full coverage 3 years 5. Support to European Neighbourhood (Pan-Eur. & Medit.) and Global Solidarity policies oSame as 4, every 5 years  Medium resolution (300m), World full coverage 5 years 6. Development of targeted land services & coordination with the European perspective (risk based data management) oMultiple requirement

28 27-28 April 2005Geoland workshop From land cover accounts to ecosystem accounts and land use accounts: services at the medium resolution?  Spatial monitoring in support to in situ monitoring of fauna and flora, e.g.: oExtent, distribution, patterns of ecosysems oPhenology, productivity oTemporary humidity, water stress oIntegrity/ fragmentation of corridors oExtreme events (storms, floods, fires…)  Nested implementation of accounts of land use functions (urban, food/agriculture, other rural landscape functions, tourism, transport, industry…), e.g.: oDensification/sealing of urban discontinuous fabric oIntensification/ extensification of agriculture oIrrigation oAssimilation with local data (maps & stats…)
