A Framework for Assessing Cumulative Effects in Watersheds: An Introduction to Canadian Case Studies

0
From 2008 to 2013, a series of studies supported by the Canadian Water Network were conducted in Canadian watersheds in an effort to improve methods to assess cumulative effects. These studies fit under a common framework for watershed cumulative effects assessment (CEA). This paper presents an introduction to the Special Series on Watershed CEA in Integrated Environmental Assessment and Management including the framework and its impetus, a brief introduction to each of the papers in the series, challenges, and a path forward. The framework includes a regional water monitoring program that produces three core outputs: an accumulated state assessment, stressor‐response relationships, and development of predictive cumulative effects scenario models. The framework considers core values, indicators, thresholds and use of consistent terminology. It emphasizes that CEA requires two components, accumulated state quantification and predictive scenario forecasting. It recognizes both of these components must be supported by a regional, multi‐scale monitoring program. Integr Environ Assess Manag © 2013 SETAC
