WG3 : session Mitigation options Factsheets: today about 81 factsheets (written for public with a higher education: catchment managers, advisors, policy makers, researchers) Report: was delivered by the end of 2010 (chapters with overall information of the categories and the factsheets delivered): http://www.cost869.alterra.nl/report2141.pdf Website: Information about the factsheets on the effectiveness of measures under different circumstances (everybody is invited to bring in information) Dbase: this meeting WG3 session; which measure can be useful in different regions within Europe

Session WG3 : The Organic Process (TOP) First day event First group; defined important cases defined solutions Rating most important factsheets Second group; defined more cases; but one of the subgroups started to make a table / selection criteria Outcome about 20 cases ideas for setting up a Dbase MC: positive advice to use the final money for setting up the database (1 day meeting) Evening: draft setup of selection criteria was made
Session WG3 : The Organic Process (TOP) Second day event Third group; group discussion about the selection criteria what is missing etc. Outcome: complete overview of selection criteria for the Dbase

Session WG3 : The Organic Process (TOP) Second day event Fourth group; what to do??? Discussion: Starting point: problem is known incl. CSA Not all criteria are relevant in relation to the problem (NO 3 leaching; P losses / P-concentration surface water; N losses / N- concentration surface water) Describe for each problem the key criteria/parameters (for surface water e.g. use the conceptual framework; source, mobilisation, connectivity) For each criterion describe if the factsheet is relevant highest total fits most important factsheet to read

Session WG3 : The Organic Process (TOP) So, 4 group discussions of about half hour About 20 solutions for 20 defined problems in different areas Ideas for setting up a Dbase Commitment from the MC Bring forward a Dbase by a one day small meeting to select the most important 5 15 factsheets to look at for a specific problem (NO 3 leaching; P losses / P-concentration surface water; N losses / N-concentration surface water) for different regions/circumstances in Europe Open source code (MS Access) Will be sent around to all of you. Open so you can put in more specific information Useful for watershed managers, agricultural advisors, teaching,...
