Spatial dimensions of supporting rural policy in Scotland 150th EAAE Seminar The spatial dimension in analysing the linkages between agriculture, rural development and the environment Keith Matthews*, Dave Miller, Mike Rivington, Doug Wardell-Johnson, Davide Cammarano James Hutton Institute, Craigiebuckler, Aberdeen

Introduction Since 2008 working in policy support, CAP and related issues Background in farm DSS, geographical information systems, modelling Larger datasets – integration and improvement Progressive integration of administrative and science based datasets Sources and integrations Example derived datasets Use of datasets in policy support Woodland expansion – changes in C stocks and emissions CAP 2015 reforms – direct payments and related Social metabolism – alternative performance metrics Ongoing activities and opportunities

Spatial data integration

Land use/cover data: coverage and granularity

Capability vs. use

Stocking rates Land use + stock numbers (Census) Field or Holding level Varying reliability

Change in carbon stocks

Woodland expansion outputs

CAP direct payments regionalisation Matthews et. al (2013) Land Use Policy

10 Options analyses Region – Farm Level – Land Type Budget – Production Weighted Podium weighting towards permanent grasslands (+20% vs. best land) Redistribution €267M with a budget of €642M

11 Options analyses – cont. Region – Farm Level – Land Type Budget – Production Weighted

CAP – implementation & Greening

Social metabolism Energy, material and value Differentiating sources Translation across energy hierarchy – seJ Emergy systems (Odum) Applied to Scot Ag CNP Ag Scot economy Internationally (NEAD) External referent

Soc-met – alternatives to GDP

Alternative system views – flows, networks

Going forward Policy support – Greening, ANC definition and regionalisation Farm Accounts Survey integration Regional yield modelling Networks – supply chains (CTS and ScotEID) Empirical agent based modelling Collaborations for policy or science
