1. CLC land cover, land use accounts and agri-environment (policy) analysis
Jan-Erik Petersen

2. Some general points Perspective of AE analyst
What are the strengths of CLC?
How far can we go with one data set?
How far can we go with data integration?
Levels of AE analysis?

3. A picture of reality(?)
- Member State level
Cubism/patterns of reality – EU level
Abstract painting –
data for outcome &
Cost-benefit analysis (?)

4. Analytical boundaries
Focus on output/environm. effectiveness:
Is there farm management change?
Is effort targeted on environmental problem areas?
Are we successful in achieving policy or scheme objectives?
Not addressed: cost effectiveness and
monetary evaluation

5. Questions for agri-env. analysis
Level of spending by country/region?
Absolute and relative uptake figures?
Which environm. issues addressed?
What % of UAA / targeted habitat?
Targeted on environmental resources at risk / on Natura 2000 sites?
Positive environmental outcome?

6. Platform for Integrated Spatial Assessment of Land, Biodiversity & Water, based on Corine Land Cover

7. Example of spatial integration (1): Potential connectivity of Natura2000 sites
Rivers
(p.m. Wetlds, lakes)
Landscape Natural Potential
EEA/Land Accounts Project
Provisional results (Nov. 2004)

8. Example of spatial integration (2) N2000 & Agriculture
Portugal-Alentejo
Farmland
abandonment
Spain - Huelva
Spain –
Huelva
Natura 2000 sites
Cultivation of marginal land
Rivers
(p.m. Wetlds, lakes)
Landscape Natural Potential

Provisional results (Nov. 2004)

9. Example of spatial integration: N2000 & Urban Sprawl
over semi-natural
land
C. de Madrid
Comunidad de Madrid
Portugal-Algarve
Algarve
Total urban sprawl
Landscape Natural Potential
Natura 2000 sites
Roads

10. Example of spatial integration: N2000 & Urban Sprawl Coastal perspective
over semi-natural

Total urban sprawl
Landscape Natural Potential
Natura 2000 sites
Roads
Potential conflicts
in land use:
urban vs. conservation

11. Differentiation of landscape, agriculture NW Europe & New member countries
Missing
data
by Nov.
2004
Intensification:
conversions
pasture to arable
Important
conversions
arable to pasture &
withdrawal of farming
Fast
agriculture
restructuring
Delayed process ?
Landscape Natural Potential

12. Land cover accounts based on CLC2000 are used for IRENA 12 (below) & 24
IRENA12 “land use change” measures the use of farmland by urban and infrastructures development.
Results are presented by NUTS3
Same results using the 3x3 km spatial grid of land accounts

13. From land to water: example of integration need: soil humidity
Soil humidity can be efficiently measured by combining space and in situ monitoring and modelling. The parameter is used for measuring, modelling and assessing:
evapo-transpiration
water stress on ecosystems
water stress on crops
crops yields
seasonal water deficits
extension of irrigation
desertification processes
buffering capacity of soil
risks of fire
risks of flood

14. Questions for agri-env. analysis
Level of spending by country/region?
Absolute and relative uptake figures?
Which environm. issues addressed?
What % of UAA / targeted habitat?
Targeted on environmental resources at risk / on Natura 2000 sites?
Positive environmental outcome?

15. Some final thoughts..
How can we adjust analytical complexity to resources available?
Prefer simple / robust solutions to complex ones
Data, analytical integration may lead to more trouble than it is worth
Sector perspective: if we are too far ahead of simple policy questions we may miss the target.
