This paper examines the experience with regional cumulative effects assessment (CEA) in the Great Sand Hills, Saskatchewan, Canada, and the lessons that emerge for better practice. The benefits of ...

The need to better assess and manage the cumulative effects of human development is well recognized; however, the practice of cumulative effects assessment has been constrained by the current proje...

This paper examines methods promoted and used in strategic environmental assessment (SEA) practice, practitioner choices about methodology and the nature of SEA guidance. Results show that SEA is not challenged by a lack of methods, but the range of methods promoted and used is restrictive. A major challenge to practice is making the ‘right choices’ about methods and methodology. Much SEA guidance is focused on flexibility in SEA, providing high-level principles, and is too generic to facilitate such choices. It is assumed that there is sufficient expertise amongst SEA practitioners, and that practitioners will simply know what methods and methodologies are best. Our results indicate that more detailed operational guidance is needed at the practitioner level on how to make sound methodological choices and how to select the best available methods for the SEA tier and context at hand.

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.
