Jan-Erik Petersen
Some general pointsSome 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?
A picture of reality(?)- Member State level
Cubism/patterns of reality – EU level
Abstract painting – data for outcome &Cost-benefit analysis (?)
Analytical boundariesAnalytical 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
Questions for agri-env. analysisQuestions for agri-env. analysis
1. Level of spending by country/region?
2. Absolute and relative uptake figures?
3. Which environm. issues addressed?
4. What % of UAA / targeted habitat?
5. Targeted on environmental resources at risk / on Natura 2000 sites?
6. Positive environmental outcome?

Land cover accounts based on CLC2000 are used Land cover accounts based on CLC2000 are used for IRENA 12 (below) & 24for IRENA 12 (below) & 24
IRENA12 “land use change” measures the use of farmland by urban and infrastructures development.
Results are presented by NUTS3Same results using the 3x3 km spatial grid of land accounts
From land to water: From land to water: example of integration need: soil humidityexample 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

Some final thoughts..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.
