To address the obvious gap in
effectiveness of existing policy instrument in environmental protection,
SEA has been introduced, putatively as the more promising tool
in several important government documents including in the 10th
NESDP 2007–2011, as well as in the current National Environmental
Quality Management Plan 2007–2011
One example is the pollution in Map Ta Phut,1 one of the most
important industrial areas in Thailand, which finally has become the
national public agenda and has triggered change in relevant
legislations.
