Our view on the use of Remote Sensed data for

Cross CompliancePhilippe LOUDJANIMARS-PAC, JRC Ispra


Background

2005-2007 test of use of RS for GAECs control

Which GAECs detected with RS?Which methods to use?Quantification of resultsUse for risk analysis?Other elements possibly detected (SMRs, AEM …)?


Results obtained so far

Erosion

Stubble burning

Maintenance of terraces

Maintained

Abandonned

Exceeding livestock stocking rate

Poaching

Maintenance of olive groves

Trees recently pruned

Several elements distinguishable

But…



Distinguishable but:

Almost only via photo interpretationHardly applicable on large extentsNeed of confirmation with field inspection

Anyway farm visit has to be done

No or few quantification of resultsNo feedbacks in the ‘summary statistics’Needed to assess the efficiency (justify additional costs)



No use for Risk AnalysisSize of sample limited 1%Mainly CAPI

Implementation hard on large extentsCostly

Few specific imagery requests by MSExcept for Winter coverAnd small tuning of SPS windows


So what to do presently?

Support office work on each dossier before systematicfield visit(When GAEC sample is part of the CwRS one)

Locate parcels with possible infringementsPossibly estimate the extent of infringementProduce piece of evidence to farmers

Field control faster and more efficientG1.2.1

Stuble burned


Needs for office work support?

Booklet for interpreters and controllers

Ground truth photos of infringementsCorresponding imagery

Screen display of examplesExpertise for infringement detection

Visual interpretation keysAutomatic processingAncillary data to use

Diagnostic codes to use


Ground truth collection - Booklet

Soil erosion – Soil structure (Avoid heavy poaching)Examples from the field Examples from imagery

Specify:- Type of satellite or aerial photography- Date if acquisition- Spectral bands combination- Code to apply- ...

Feeder

Provide elements of expertiseIndicate rules to follow:- Area measurement or not- Take photo as evidence- Sanction or no sanction


Provide detection strategy

Soil erosionDetection of ploughing and/or crop rows direction

Use of additional layers

Use of additional layers to check where GAEC applyIACS-GIS, Natura 2000, DEM, vulnerable zones, Rivers network …

Evidencing infringements

Use of diagnosis codesG1.1.1 Obligation of minimum soil cover in winterG1.2.1 Prohibition of certain crops on slopes > 10%G2.2.1 Prohibition of burning stubblesG3.0.1 Avoid heavy poaching by animalsG4.4.1 Avoid unwanted vegetation on arable land

Sub conclusion

Ease and optimise the work of controller on the field



Extend the use of RS imageryReport also infringements out of GAEC sample

Admin to decide for follow upLetter to farmer, warning, high risk for next campaign …



Extend the use of RS imageryDetect or control also SMR, AEM ?

Sludge, organic storage, leak, pollution evidence



Extend the use of RS imagery

Combine GAECs’ criteria with SPS for Risk AnalysisSelection of CwRS sitesGAEC sample within CwRS sampleAfter update of 796/04 legislation

Possible increase of number of targeted CC controls

Possible change number and size of sitesReduce size, increase number

Lead to an increase of controls



Provide relevant information to farmers (digital, paper)Increase awareness on Cross Compliance (FAS)Reduce risk of infringements

Satellite imagery + additional GIS layersLocation of: Parcels in vulnerable zones, rivers and green cover buffer, landscape features to maintain…


Optimise the use of RS imagery

Prepare the field workDetect GAEC infringement

Detect SMR infringementCheck AEM

Provide documented application

Support risk analysis
