11. Cumulative Effects Assessment

  • Overview
  • Description
  • Trainer Info

The two day Cumulative Effects Assessment and Management (CEAM) course aims to teach participants what cumulative effects are, how to identify and predict them, and how to mitigate them.  CEA considers effects on receptors rather than the effects of a plan/project, and so requires a different mindset from 'normal' impact assessment.  The course discusses how to identify affected receptors, techniques for assessing and evaluating cumulative effects, and what 'other plans and projects' should be considered in CEA.  Cumulative effects usually require 'cumulative mitigation', which in turn requires the collaboration of multiple institutions: the course will address some of the issues surrounding this, and how to overcome institutional constraints.  It will examine several successful CEA analyses and mitigation measures, and include a range of workshops.  Participants are encouraged to bring 'cumulative effect problems' with them, for discussion during the course.

Course description

The two day Cumulative Effects Assessment and Management (CEAM) course aims to teach participants what cumulative effects are, how to identify and predict them, and how to mitigate them.  CEA considers effects on receptors rather than the effects of a plan/project, and so requires a different mindset from 'normal' impact assessment.  The course discusses how to identify affected receptors, techniques for assessing and evaluating cumulative effects, and what 'other plans and projects' should be considered in CEA.  Cumulative effects usually require 'cumulative mitigation', which in turn requires the collaboration of multiple institutions: the course will address some of the issues surrounding this, and how to overcome institutional constraints.  It will examine several successful CEA analyses and mitigation measures, and include a range of workshops.  Participants are encouraged to bring 'cumulative effect problems' with them, for discussion during the course.

Summary

The premise of this course is that CEAM should be an integral part of, and not separate from other EIA/SEA processes.  The course presents stepwise procedures associated with international best practice CEAM principles: identifying key environmental receivers / valued ecosystem components (VECs) and their spatial and temporal boundaries; describing historical baseline conditions and trends; identifying cause-effect linkages between past, present, and future actions and environmental receivers; predicting and evaluating the significance of cumulative effects; and developing follow-up adaptive management/mitigation.

This intermediate/advanced level course aims to:

  • summarize the state of professional practice regarding CEAM
  • discuss the steps of CEAM, including potential problems faced and real-life case studies
  • apply CEAM procedures to two case studies
  • consider approaches to cumulative effects mitigation and management

The course focus will be on practical approaches for management of cumulative effects, including the use of emissions trading, biodiversity or other offsets, and collaborative/strategic planning. Interchange of information and experiences among the participants will be encouraged. The anticipated learning outcomes are achieving a better understanding of the principles and practices of CEAM, and the ability to effectively apply them in study planning and implementation.
