This is a 2003 paper by Polsky, Colin, Dagmar Schröter, Anthony Patt, Stuart Gaffin,Marybeth Long Martello, Rob Neff, Alex Pulsipher, and Henrik Selin, published by the Belfer Center for Science and International Affairs, Kennedy School of Government, Harvard University. The paper summarizes the main findings of a workshop held at Harvard University where participants discussed methodological guidelines for researching vulnerability to the effects of social and environmental changes. Results from the workshop explore the issue of methods and models for vulnerability assessments and include an objective for global change vulnerability assessments, a set of five information criteria that vulnerability assessments should satisfy for achieving this objective, and a set of eight steps designed to satisfy those criteria.
