Background 1. Reference is made to EIHA 08/3/9-E addressing the socio-economic assessment of the marine environment. 2. On the occasion of the Conference of Parties to the Convention on Biological Diversity (CBD COP) held in Bonn, Germany in May 2008, WWF presented the global study at Annex 1 including case studies and personal witnesses of the socio-economic importance of our oceans. Action requested 3. EIHA is invited to take note of the report presented by WWF and make use of the approach and information included as appropriate. 1 of 1 OSPAR Commission EIHA 08/3/10-E The Value of our Oceans The Economic Benefi ts of Marine Biodiversity and Healthy Ecosystems WWF Deutschland 1 Introduction People love the oceans.
