In 2005, Cortex presented a half-day workshop on cumulative impacts assessment (CIA) and cumulative impacts management (CIM) to the Treaty 8 Negotiation Team, including representatives from the Oil and Gas Commission and the B.C. ministries of Sustainable Resource Management; Water, Land and Air Protection; and Forests. The purpose of the presentation was to clarify terminology and introduce basic concepts of CIA, discuss how CIA is being used in British Columbia's resource development and assessment processes, overview various approaches to CIA, and discuss a framework for CIM.
