Inhabiting the Shifting Edge: Increasing the Adaptive Capacity of Coastal Sand Spit Communities in a Changing Climate

This masters thesis uses urban design and landscape architecture to investigate the role of open spaces in increasing the adaptive capacity of New Zealand's sand spit communities in the face of climate related change. In order to respond to potential climate related change, the design of open spaces should acknowledge the crucial role that natural processes and ecosystems play in protecting coastal environments. Urban design and landscape architecture have the potential to encourage interaction at the interface of the social and ecological systems within these coastal communities. The design of public open space can encourage more sensitive development patterns and increase the communities' awareness of coastal processes. These spaces can become the focus of social capital building while ensuring the environment has the capacity to absorb potential climate related changes. This research focuses on three sand spit resort communities on the east coast of New Zealand's North Island. Through a series of design studies, a range of strategies are proposed and tested in response to the potential impacts of climate change and sea level rise. The exclusive and expensive coastal development trend is augmented to provide for all potential beach users. Diversification in both the users, and types of use, in these coastal areas will increase the social capital investment and awareness, further building the adaptive capacity of the spit system.
