Assessing the assessments: Improving methodologies for impact assessment in transboundary watercourses

Abstract

Transboundary impact assessment (TIA) has become an important environmental management tool, particularly where a project may have transboundary impacts. With the growing practice of TIA, it becomes important to consider the accuracy of the transboundary impact assessments that are being conducted. If TIA is a planning tool designed to provide a basis for making an informed decision, does it actually provide the necessary information? This paper summarizes lessons learned in pilot-testing a methodology to assess the accuracy of TIAs. © IAIA 2008.
