 +<​P>​The basic methodology for spatial down-scaling had been jointly developped by the Joint Research Centre and the Institute for Institute for Food and Resource Economics, University of Bonn,
 +
 +  to a large extent in the context of the <a class="​intext"​ href="​http://​www.ilr1.uni-bonn.de/​agpo/​rsrch/​dynaspat/​dynaspat_e.htm">​CAPRI-Dynaspat project</​a>​. The team from JRC comprised members
 +
 +  of the AgriEnv action, as well as of the Climate Change Unit.
 +
 +  The down-scaled data are produced by statistical estimators for <a class="​intext"​ HREF="/​dokuwiki/​doku.php?​id=capri:​concept:​SpatCrops">​cropping shares,</​a>​ <a class="​intext"​ HREF="/​dokuwiki/​doku.php?​id=capri:​concept:​SpatYields">​crop yields</​a>,​

 +   <a class="​intext"​ HREF="/​dokuwiki/​doku.php?​id=capri:​concept:​StockDens">​animal stocking densities</​A>,​ and <a class="​intext"​ HREF="/​dokuwiki/​doku.php?​id=capri:​concept:​spatFert">​fertilizer application rates</​a>,​ starting from the regional data base
 +
 +  of CAPRI. The data presented online ​ cover a three year average 2001-2003, but data set had also been projected to 2013 and estimated for counter-factual policy scenarios.</​P>​
 +
 +
 +
 + <​P>​The data and methodology allows the <​I>​AgriEnv</​I>​ action at JRC-IES
 +
 + to perform environmental impact assessment of the Common Agricultural Policy, both ex-ante as in a forward looking exercises. <​i>​Agri-Env</​i>​ has in 2007 used the methodology to
 +
 + ​forecast the probable development of gross nitrogen balances and the share of High Nature Value farmland in the EU up to 2013, in close co-operation with DG-AGRI and
 +
 + the <a class="​intext"​ HREF="​http://​www.jrc.es/​activities/​agriculture/​sustag.cfm">​SUSTAG</​a>​ action of IPTS/​Sevilla. For 2008, an analysis of impacts of increased bio-fuel production in the EU is planned by down-scaling and analysing results of CAPRI bio-fuel scenarios.
 +
 + Parts of the down-scaled data set are used in large-scale European research projects as <a class="​intext"​ href="​http://​www.seamless-ip.org/">​SEAMLESS</​a>​ and <a class="​intext"​ href="​http://​www.lucsus.lu.se/​html/​sensor.aspx">​SENSOR</​a>​.<​P>​
