Assessing the impact of strategic environmental assessment

This paper examines the impact of strategic environmental assessment (SEA) – its direct impact on policies, plans and programs (PPPs) and its indirect and longer-term impacts. Criteria for assessing SEA's impact are developed and applied in the Canadian context based on a survey of SEA practitioners, and the perceived opportunities and challenges to realizing the full impact of SEA explored. Results indicate that SEA does have a direct impact on PPPs, but its indirect impacts are either constrained or difficult to distinguish from an agency's normal policies, practices and innovations. Amongst the most significant challenges to realizing the indirect impacts of SEA is the lack of shared vision for SEA by those responsible for implementation, and incongruences between the need for rapid results by way of PPP approval versus the long-term commitment required to realize many of the benefits of SEA. Indirect impacts require more explicit consideration at the outset of the SEA design process than what is currently the case if the benefits of SEA are to be fully recognized.
