A workshop was held in Bonn, Germany, on 8 June 2011 to further develop ways to enhance the engagement of observer organizations. The workshop featured presentations by Parties and representatives of eight constituencies of non-governmental organizations on proposals for enhancing the existing means of observer participation and for creating possible new means of participation. The secretariat made presentations outlining current practices for observer participation, good practices of other United Nations processes and virtual participation. Parties and observers engaged in a frank and open discussion of issues relating to the proposals. The discussions will serve as an input to the consideration of this matter by the Subsidiary Body for Implementation at its thirty-fourth session
