| | <P><B>Environmental impact assessment</B> of farm management decisions is often only possible in a spatial context, taking local conditions as land cover, climatic and soil conditions |
| | |
| | into account. Equally, farm management decisions depend to a larger extent on those local factors. Therefore, CAPRI aims at developping |
| | |
| | data bases and tools at an appropriate spatial resolution to support monitoring and ex-ante assessment of environmental impacts of agriculture.</P> |

| | <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> |
