  • The systematic approach proposed above aspires for a region wide application and it reduces quantification risk with stable, class dependent photo-interpretation rules and a documented low standard deviation of the class RC. The sporadic application is by definition not subject to these restrictions. It can be expected to be more error prone and should therefore be used very carefully and sensibly. Essentially, the sporadic assessment is a grassland assessment method, as described above, on a parcel by parcel basis.
  • During LPIS creation and upkeep processes, it is used inside a single reference parcel to determine the percentage of grasses and other herbaceous forage. Good practice requires that the assessment is then well documented for that reference parcel.
  • During aid application and OTSC processes, it is used to determine the number of eligible hectares of the declared agricultural parcel. To be relevant in the scope of this technical guidance, it is assumed that the agricultural parcel concerned matches its reference parcel one to one.
  • Either application returns a percentage of the grass and herbaceous forage present. Categorize this percentage by applying the example of rules of figure of 2.6.1 of document DSCG/2014/33. It sets thresholds at 50%, 70% and 90%; resulting in categories of grassland60 and grassland80 as illustrated in the table below. The final reference area or eligible hectare follows by calculating the reference parcel geometric area or the agricultural parcel measurement with the corresponding eligibility rate.

Example of possible set of eligibility rates:

percentage [%] Pro rata category Eligibility rate
97,8 Grassland 100%
91,1 Grassland 100%
89,4 Grassland80 80%
62,3 Grassland60 60%
56,1 Grassland60 60%
44,0 Ineligible land 0%

  • Eligibility rates below 50% are not supported for sporadic assessments because the Commission Services believe such isolated cases represent too high a risk of ineligibility.
  • Although it is quite difficult to define a detailed set of requirements for the application of the sporadic methodology, some general recommendations should apply:
  • ensure that the field conditions are really unique, will not likely be found in other locations, or that no mapping methodologies are available.
  • document the methodology, the observations and transaction for each individual reference parcel. Ensure that the resulting value withstands scrutiny.
  • when applied to an agricultural parcel, ensure that the result matches a reference parcel and reflects a stable condition before updating the reference parcel's reference area. If either of these conditions is not met, flag the reference parcel for LPIS update.
