Planning For An Uncertain Future: Can Multi-Criteria Analysis Support Better Decision-Making In Climate Planning?
This paper by Ingrid Gould Ellen, Jessica Yager, Melinda Hanson, and Luke Bo'sher, published in the Journal of Planning Education and Research, examines how multicriteria analysis (MCA), a decision-making tool, compares to other commonly used tools for making decisions about climate-change planning. The authors find that MCA has the potential to perform better than cost benefit analysis and working group approaches in supporting decision making processes that are more participatory, transparent, comprehensive, rigorous, and scenario-driven (five principles of effective planning). The paper also explores the ways in which MCA might fall short of these principles in practice, including when planners have limited resources.
The American Housing Survey (AHS) is the most comprehensive national housing survey in the United States. Since 2009, AHS has included six core disability questions used in the American Community Survey. The questions address hearing, visual, cognitive, ambulatory, self-care, and independent living difficulties for each household member. For 2011, AHS added a topical module on accessibility. The module asked about the presence of accessibility features in housing units, including wheelchair accessibility features, and whether the accessibility features were used or not. Together, these data provide an unprecedented opportunity to examine the accessibility of the U.S. housing stock and to ask whether people with disabilities reside in accessible homes.
In this report, the authors present summary measures of housing accessibility based on the 2011 AHS. To develop these summary measures, they examined United States (U.S.) and international standards and regulations regarding housing accessibility, reviewed the relevant literature, and conducted interviews with a set of disability and housing design experts. These interviews are further described in appendix A. Based on these summary measures, the authors describe how accessibility varies by housing market characteristics as well as resident characteristics such as age, disability status, and income. They also present evidence on the relationship between the need for and availability of accessible housing units, taking affordability of accessible units into account.
