The Third Global Environment Facility (GEF) Assembly is being hosted by the Government of South Africa from August 29-30, 2006 at the Cape Town International Convention Centre (CTICC).
All the relevant information is at the Assembly's Website
The most interesting document I have discovered is the Scientific and Technical Advisory Panel (STAP) Report on the Broad Scientific and Technical Issues that emerged during the Preceding Phase of the GEF and on Emerging Issus and Gaps
