SEA was initially promoted to address the gaps
in project based environmental impact assessment (EIA). This
was due to the inability of EIA to address environmental policy
integration (EPI) at strategic levels especially during the policy
and plan-making process. EIA is limited in its ability to account
for the strategic impacts of cumulative effects of multiple and
successive projects in a particular area (Dennis and Agamuthu,
2012a) (United Nations, 2003)
