  1. ElpenConcepts & Calculation Structure Technical System Developments: Workshop this afternoon e-mail: info@objectvision.nlhttp://www.objectvision.nl

  2. Concepts • Elpen Farm Systems (EFS) • Farm System Groups (FSG) • ‘Model Farm’ (MF) • Reference Farm (RF) e-mail: info@objectvision.nlhttp://www.objectvision.nl

  3. Elpen Farm Systems (EFS) = The classification of FADN Farm Systems to 6 dims, which are sets of coordinates: • ElpInputType: EIT := {low, medium, high, all }, #EIT = 4 • ElpLanduseType: EUT := { offFarming, permGrass, grassland, arable, offFarmFodder, all }, #EUT = 6 • ElpLivestockType: ELT := {cattle, mixed, sheep, goats, all }, #ELT = 5 • ElpProductionType: EPT := {dairy, mixed, meat, all }, #EPT = 4 • ElpStructuralType: EST := {small, medium, large, all }, #EST = 4 • ElpGeneraltype: EGT := {grazing, … }, #EGT = 8 • for non-‘all’ systems only g=grazing is available. => EFS := { (i, u, l, p, s, g)  EIT x EUT x ELT x EPT x EST x EGT | g=‘grazing’  i=u=l=p=‘all’}; #EFS=7+1920

  4. Farm System Groups (FSG) • Used to locate EFS (using FSS, Corine/Pelcom, and Elevation/LFA data) =A disjunct set of collections of EFS elements ( = partial partition of EFS), grouped by Production-, Livestock, and Land use types (EPT, ELT, EUT) • Labeled as {beefGrass, beefArable, dairyGrass, dairyArable, sheepGrass, mixedArable } => #FSG = 6 e-mail: info@objectvision.nlhttp://www.objectvision.nl

  5. Model Farms (MF) • Locates elements of EFS in time (Periods), space(Territories) and in the EU FarmType classification (EUFT) • A model farm is a group of farms for which data is collected in the Elpen database (the set of Elpen variables) where #>15 • Each record in FADN db is a Model Farm => MF  EFS x Periods x Territories x EUFT #MF = 59.521 e-mail: info@objectvision.nlhttp://www.objectvision.nl

  6. ReferenceFarms (RF) • Actual farms that are related to a (set of) model farms (and therefore EFS). • Additional information is collected and related to model farms. e-mail: info@objectvision.nlhttp://www.objectvision.nl

  8. FSS Presentation S1_FssForMap • Case Generator Parameters: • FssVariable, • EuFarmType, • Period • Example: • NoHoldings, • ‘All Holdings’, • 1997, • Country e-mail: info@objectvision.nlhttp://www.objectvision.nl

  9. LandCover S2_LandUse_5km & ..._1100m • Case Generator Parameters: • % per corine class & Pelcom (the maximum of the two is taken), Generation of new items Example: with case generator - arable landuse e-mail: info@objectvision.nlhttp://www.objectvision.nl

  10. FSS Desaggr (for FSG’s) S3_FssDesaggration _5km & ..._1100m • S3 combines results from S1 and S2. • Case Generator Parameters: • GridDistribution (from S2) • FssData (from S1) • Preconfigured: • PermGrass: Beef, Dairy, Sheep • Arable: Beef, Dairy, Mixed • Example: • Arable/Beef e-mail: info@objectvision.nlhttp://www.objectvision.nl

  11. DairyFarmCostModel S6_FarmCosts • Case Generator Parameters: NrHoursPerAWU • Calculated for all records in Fadn db (= all MF) e-mail: info@objectvision.nlhttp://www.objectvision.nl

  12. DairyFarmBehaviourModel S7_FarmBehaviour (proposal) • Case Generator Parameters: • ProductionCost variable • Future Market Price • Price-sensitivity or Elasticiy • Calculates for all records in the Fadn db (= all Model Farms) a production change • Production Change = (market price - cost price) * price-sensitivity or elasticity • Discussion on Economic model(s): this afternoon e-mail: info@objectvision.nlhttp://www.objectvision.nl

  13. EfsForMap • Example: • all, • ‘spec-dairy’, 1997, • ER, • MilkProdCost, • Per100kg S4_EfsForMap • Case Generator Parameters: • EFS • EuFarmType, Period • territoryDomain: Country, H1, ER • Fadn related variable (also DairyFarmCost model results) • denominator  {none, nrFarms, LU, UAA, …} • (NYI) Maps with No of EFS of MF per region with a pop-up per region with occuring systems and reference farms for additional info e-mail: info@objectvision.nlhttp://www.objectvision.nl

  14. EfsForDynaCube S4_EfsForDC • Case Generator Parameters: • Fadn related variable (also DairyFarmCost results) • (NYI) denominator  {none, nrFarms, LU, UAA } • (NYI) Create Map from specific MF selection • Example: • MilkProdCost (in kEur per 100kg) e-mail: info@objectvision.nlhttp://www.objectvision.nl

  15. FSG location • Example: • Arable/Beef • UAA • Arable/Beef • ‘spec-dairy’, 1997 • H0 S5_Fadn_Allocation_5km, …_1100m Parameters: • GridProxy (from S3_FssDesaggr) • Fadn var  { LU, #Farms, UAA} • EFS • EuFarmType, Period • territory domain  {H0, H1, ER} • LFA & Elevation classes are used • denominator = gridSize in ha • Preconfigured: • PermGrass: Beef, Dairy, Sheep • Arable: Beef, Dairy, Mixed e-mail: info@objectvision.nlhttp://www.objectvision.nl

  16. DairyFarmBehaviourModel S8_FadnComposition_5km, …1100m (NYI) • Parameters: • Fadn related variable (also DairyFarmCost model results) • set of desaggregated FSG • Period, Territory, EFS, EuFarmType • Calculates a composition per grid cell based on the locatedFSG’s • Allocation & Composition will be discussed at Friday morning. e-mail: info@objectvision.nlhttp://www.objectvision.nl

  17. Remaining Issues • Nitrogen maps / critical load (Afternoon) • S9: Vulnerability & Environmental Impact Indicators • S10: Socio Economic Data (Friday) • S11: Socio Economic indicators per region (Friday) • S12: Reference Farms • Quality assurance (see installation notes) • Make some space on your harddisk before Lunch (approx. 800mb; at least 400mb will be used) e-mail: info@objectvision.nlhttp://www.objectvision.nl

  18. Discussion Points • Socio Economic Indicators • Which (combination of) indicators? • From which data sources ? • Relation with other components (RF, MF) • Environmental Indicators • Which (combination of) indicators? • From which data sources ? • Relation with other components (RF, MF)
