What Will Climate Change Mean for Martha's Vineyard?


It has been quite a while since my last post! Over the last couple months I have been focused on finishing up my M.A. in the Geography Department. Much of this time was spent on my thesis, which I wrote a post about back in February. The full text, entitled An Integrated Approach for Developing Adaptation Strategies in Climate Planning: A Case Study of Vulnerability in Dukes County, Massachusetts, is now available for download from Digital Commons @ UConn.

My goal for this project was to develop a theoretical framework that serves as a GIS-based decision support system for policy makers to determine where climate change adaptation policies are needed. This framework is operationalized through a case study of vulnerability of Dukes County, Massachusetts. Here is the abstract in full:

Climate Action Plans (CAP’s) are recent innovations in policy that have been catalyzed by a need to adjust the relationship between human activity and the Earth’s climate system. CAP’s often are composed of methods to mitigate greenhouse gas emissions in addition to adaptation strategies. Research indicates, however, that many plans focus on mitigation strategies while adaptation policies related to predicted changes caused by climate change are often overlooked. This thesis presents an integrative framework for locating areas that are in need of adaptation strategies through a GIS based decision support system that visualizes vulnerability. It is operationalized through an empirical study of Dukes County, Massachusetts.


Dukes County is a New England county composed of the islands of Martha’s Vineyard and Gosnold. The county has a long history of commercial fishing, but more recently caters to affluent seasonal tourists. With both economic activities heavily reliant upon the ocean as a resource, climate sensitive hazards, such as sea level rise and tropical storms, pose an important risk to the population, built environment, and the natural environment that has made the study area a highly desirable New England tourist destination.

The results of my case study conclude that long term climate processes have shaped the way in which Dukes County has developed through the geomorphic influence of the last glaciation. The up-island towns of Martha's Vineyard (Aquinnah, Chilmark, & West Tisbury) and Gosnold differ in geography- both physically and socially- from their down-island counterparts (Edgartown, Oak Bluffs, & Tisbury). This geographic variation results in an unequal distribution of vulnerability related to climate sensitive hazards distributed throughout the county. I have quantified this vulnerability through examining the amount of various land types that could be impacted by climate sensitive hazards (sea level rise and storm surge events) in addition to creating a social vulnerability index for the seven county subdivisions in the county. Maps of the location of important infrastructure related to worst case storm surge are also available in Appendix D. Generally speaking, my study concludes:

Flatter land that is also lower in elevation down-island has traditionally been developed and inhabited more than the up-island land of Martha’s Vineyard and the islands of Gosnold. Consequently, larger populations and more developed land are at risk to hazards whose exposure is largely dependent upon elevation, like storm surge and sea level rise (down-island).
