Monique Dubé, Guest Editor of the IEAM special series “Watershed Cumulative Effects Assessment,” joins us to talk about the application of cumulative effects assessments to Canadian watersheds. Cumulative effects assessments (CEA), which account for the accumulated change over time—past, present, and future, have been employed in limited situations in Canada and with limited success. Dubé describes the novelty of the work presented in this special series, which include a detailed framework for employing watershed CEA, identification of inconsistencies in both environmental assessment practice and long-term data that impede watershed CEA, and several case studies where watershed CEA was conducted in seven Canadian watersheds. Going beyond traditional effects- and stressor-based approaches, the watershed CEA incorporates both the existing condition of a watershed and predictions of its future condition to better inform planning and management efforts. Access the special series in the July 2013 issue of IEAM.

Bio for Monique Dubé

Dr. Monique Dubé

Dr. Monique Dubé is a Project Coordinator in Environmental Performance Improvement at Shell Heavy Oil in Calgary, AB, Canada. She is also an Adjunct Professor in the Department of Biology at the University of New Brunswick (Saint John campus) and a Science Director of the Canadian Rivers Institute. Previously Monique was a Canada Research Chair in Aquatic Ecosystem Health Diagnosis at the University of Saskatchewan and has operated in the consulting and regulatory sectors with over 20 years of professional experience. Her area of interest is in integrated water resource management and watershed-scale cumulative effects assessment. She has published over 180 contributions, is the recipient of an NSERC Synergy Award, and in 2011 was awarded Canadian Geographic Scientist of the Year and a YWCA Women of Distinction. Her work has influenced federal legislation, national environmental impact assessment practices, cumulative effects assessments for Canadian freshwaters, and contributed to patented technology for wastewater treatment. She has served on Scientific Advisory Panels for UNEP, UNESCO and Canada/US Partnerships. She has participated in peer reviews of the Alberta oil sands Regional Aquatic Monitoring Program (RAMP) and was a member of the development team for the recent federal/provincial regional monitoring program in the oil sands. Her THREATS software (The Healthy River Ecosystem AssessmenT System) and watershed health assessment approach has received international attention for its contribution to assessing and managing Canadian watersheds towards sustainability.
