摘要

Valued ecosystem component (VEC) selection is a core component of cumulative effects assessment (CEA) and gives direction to impact analysis, mitigation and monitoring. Yet little is known about CEA VEC selection practices. This paper examines 11 Canadian road infrastructure project CEAs completed between 1995 and 2011 to determine how VEC selection in CEA is performed, and whether these practices are sensitive to the linear project development context. Document review and semi-structured interviews reveal an absence of VEC selection guidance, late timing of cumulative effects considerations in impact assessment, lack of sensitivity in CEA VEC selection to the unique, linear nature of the road construction projects and a general lack of insightful, creative approaches to CEA VEC selection – ones that better reflect potential impacts to social and economic aspects of the environment – despite it being shown to be a values-driven, subjective process. There is a clear need for regional databases to support consistent CEA VEC selection processes, and the development of CEA-specific VEC selection guidance.
