The World Space Environment Forum 2007 took place 20-25 October 2007, at the Bibliotheca Alexandrina Conference Center (BACC).

WSEF 2007 was organized, jointly, by the BA Planetarium Science Center (PSC) and the World Institute for Space Environment Research (WISER) of the National Institute for Space Research in Brazil.

WSEF 2007 aimed to review the state of space environment research, and to identify the key problems in Sun–Earth relation to be addressed by the international solar-terrestrial science community in the coming years. WSEF 2007 provided a forum for elaborating international collaboration programs on research and training on the earth–ocean–space environment.

WSEF 2007 is the 3rd World Space Environment Forum. The first WSEF was hosted by the University of Adelaide in 2002 in Adelaide, Australia. The second WSEF was hosted by the Space Research Institute of the Austrian Academy of Sciences in 2005 in Schloss Seggau, Austria.
