On 19-21 February 2003 the international conference entitled "EU: CAP and Enlargement – An Opportunity for Environment and Nature?" took place in Potsdam, Germany. The primary goal of the conference was to analyse and discuss the complex interactions between EU enlargement, the Common Agricultural Policy and the related impacts on nature and environment. In October 2003 conference proceedings have been published in the series BfN-Skripten of the German Federal Agency for Nature Conservation.
