Challenges to incorporating social and economic factors into cumulative effects assessments in Canada’s marine conservation areas

Abstract

The cumulative effects of human stressors are threatening marine ecosystems. While spatial management tools such as marine conservation areas can help mitigate cumulative effects, several decision-making challenges remain. A limited availability of information and lack of knowledge, inconsistent management approaches, and ineffective consideration of social-ecological interactions hinders current cumulative effects assessment and management efforts. We examined if and how ocean managers assess cumulative effects and incorporate them into their management practices. A survey of the three Canadian federal departments responsible for marine conservation areas was conducted, and focused on the extent to which social and economic factors are considered. Managers seemed to favor ecological factors over social and economic ones when evaluating cumulative effects, such as when defining the spatial and temporal scales to use in their assessments. Managers also indicated a need for greater access to social and economic data and information to improve their assessment and management decisions. Lastly, the lack of a standardized cumulative effects assessment framework and fragmented management approaches appeared to limit managers’ ability to adequately incorporate social and economic factors into assessments. The survey results indicated that a cumulative effects assessment framework that explicitly includes social and economic factors in addition to an enhanced understanding of the suite of factors that influence social-ecological interactions should be developed. This type of framework is essential to help achieve the long-term management solutions required to conserve the health and integrity of Canada's oceans and beyond.
