Desiging phosphorus cycle at country scale

5th July 2011 - 6th July 2011

The European scientific workshop on Desiging phosphorus cycle at country scale will be held in Bordeaux, France

The current depletion of available phosphorus (P) resources is a concern for sustainable agricultural production. It calls for an urgent analysis of key driving forces underlying global P resource consumption. Large scale studies on P cycling in society are therefore necessary. Designing P cycles at country scale provides insight on internal fluxes, stocks, import and export. It allows to identify recycling opportunities and options for a better management. However, many scientific as well as technical questions remain about the design method and results. This workshop aims at gathering European scientists working in the field of phosphorus sustainability to share their ideas, methodological approaches and findings with fellow scientists. The benefits, outcomes and challenges of quantifying P cycles at country scale will be discussed. Future research collaborations on linking system approaches of P flux calculations and mathematical modelling of P cycles at different spatial scales will be outlined.

Please find detailed information of the workshop in the attached leaflet. This workshop is dedicated to cooperation between European scientific teams working on P cycling at country scale. There are opportunities for participants to present a case study (either oral or poster) and to chair a session. If interested, you can mention your willingness in the registration form.

If you intend to participate in the workshop, please fill in the registration form (see attachment) and send it back to:

The deadline for the registration is 10th June, 2011. However, early registration will be given priority as the maximum number of participants will be around 25.

The cost of travel and accommodation should be arranged by the participants on their own.
