Changing global temperatures will have numerous repercussions on our planet, including drastic climatic changes and sea-level rise. Even a minor increase in sea level will have significant effects on coastal environments, including those within national parks. In hopes to begin addressing these issues, the Program for the Study of Developed Shorelines at Western Carolina University (WCU) has partnered with the National Park Service (NPS) to identify resources and infrastructure at risk to rising sea levels and the long-term adaptation strategies associated with that risk.
The first phase of this collaborative project is focused on identifying all NPS assets that may be threatened by a future 1m rise in sea level, within 41 coastal park units. This element of the project utilizes an existing database (NPS Facility Management Software System) containing a comprehensive list of assets within each of the park units. The primary objective of this analysis is to locate each asset geospatially and then indentify its approximate elevation. Although this seems relatively straightforward, there are over 10,000 assets within these 41 coastal units. Therefore, a variety of methods are being used to complete this analysis, including collaboration with park staff and visits to manually locate assets.
The second phase of the project is to create a manual containing long-term sea-level rise adaptation strategies. This manual will include a complete list of options for adaptation that a park manager or decision maker may use when an asset or resource becomes at-risk. Included with each option will be real-world examples and the advantages and disadvantages (both economic and environmental) associated with that particular strategy. This project will allow park managers to better understand vulnerability to long-term sea-level rise and, therefore, make more informed decisions on appropriate options for adaptation.
