Context and Background
3
Context Significant spatial variability in agriculture in Ireland Better land in the South and East Poorer land in the North and West Water Quality is spatially dependent Significant reliance on off-farm income Spatial variability in labour markets Location specific costs – e.g. transport costs Spatial dimension to Direct Payments A function of historical production which is location related Disadvantaged Areas HNV’s Localised REPS/AEOS

Ideal Data Ideal Data Farm Survey Income Data Spatial Scale Detail Farm Management Information However Not available Census – Spatial Teagasc NFS – Income and Management Information Spatial Microsimulation in Agriculture Ireland: Hynes et al. (2009b), Hennessy et al., (2007), O’Donoghue (2013) The Netherlands: Van Leeuwen et al. (2008) Sweden: Lindgren and Elmquist (2005) Landscape services from Agriculture (Pfeiffer et al., 2012) Participation in Rural Environmental Protection Schemes, (Hynes et al., 2008)

Methodology Data Enhancement or Sampling Methodology Spatial Microsimulation Currently on third version Much improved speed and accuracy Choice of Methodology (Hermes and Poulsen, 2012) Iterative Proportional Fitting (Deming and Stephen, 1940) Deterministic Reweighting (Ballas et al., 2005) Regression Based Reweighting (Tanton et al, 2011) Combinatorial Optimisation (Williamson et al., 1998, Ballas and Clarke, 2000) Quota Sampling (Farrell et al. 2013) Chosen because other methods have issues with Areas with small sample size Runtime Incorporating local stocking rate
6
Methodology Sample Farms from Teagasc National Farm Survey/Irish FADN (NFS) to generate spatial samples with same structure as Census of Agriculture By Size, System and Soil Type NB not the same farms, merely the same characteristics Adjustment to ensure that stocking rates are compatible Challenges NFS is not representative of the smallest farms and on land with poorest quality Cell sizes can be challenging Choice to sample from within region/LFA Post-sample Adjust for Differences in Income Variability

Validation Methodology 12 Alternative Choices Validate against Census variables Local stocking rate Winners and Losers from CAP reform at regional level (using NFS analysis) Correlations of Best Method Census Variables ~ 90% Stocking Rate ~ 70% Caution on peninsulas, due to limited number of small farms However good across main farming areas Correlation Range for 12 Choices

Tillage Dairy Beef and MixedSheep Tillage – East and South Dairy – South Beef – Midlands and West Sheep – West and North West
15
Farm Incomes Farm Income/ha Market Income/ha Direct Pay per ha Incomes Higher – South and East of Kerry-Dundalk line Direct Payments reflect both SFP and Disadvantaged Areas
16
Viability Viable Income > Min Wage + Return on investment Sustainable Not Viable but with job Vulnerable Not Viable, no job Viability – reflects higher incomes Sustainable in West and Midlands Vulnerable North West, Border, Coast

Spatial Distribution Between DistrictWithin District Baseline Direct Payments17.882.2 Family Farm Income14.585.5 Far more variability between farms than between areas But many winners and losers within the same areas
18
Next Steps Solve the peninsulas/small farms issue Methodology is currently being used in 3 other countries Utilises data that is available in all EU members states Pitch to EU Commission to fund development for all EU members states for use in EU CAP and RDP policy analysis Gap in capacity at the moment Model future Less Favoured Area reforms Improve the consistency with localised environment
