Abstract
This thesis investigates the challenges and opportunities for maintaining access to the coastal community of Ngāwī, New Zealand, in the face of climate change. The study explores community perspectives, planning and decision-making processes, and funding options for adaptation solutions to protect vulnerable infrastructure, particularly Cape Palliser Road - the only access route connecting Ngāwī to the wider Wairarapa region. Of the 35km length of Cape Palliser Road, 16km leading to Ngāwī runs along a coastline already experiencing significant erosion.
As climate change intensifies the frequency and severity of hazardous events, rural coastal communities like Ngāwī face heightened risks. This research identifies the complex physical, financial, and governance challenges impacting continued access, including increased storm events, fragile geological conditions, and limited capacity of local council. Through qualitative key informant interviews with community members, policymakers, and experts, and a review of existing policies, the study highlights community concerns about potential isolation due to road closures, especially for vulnerable populations.
The findings point to several adaptation strategies, including continued use of eco-friendly engineering solutions, leveraging local knowledge, and exploring innovative funding mechanisms such as a community investment fund. While there is debate over whether central government or local communities should bear the costs of adaptation, this study underscores the need for a balanced approach to resource allocation. The research also evaluates the applicability of the Dynamic Adaptive Pathways Planning (DAPP) framework, emphasising its potential for proactive planning but noting challenges in its implementation for smaller, resource-constrained communities. By providing insights into these challenges and opportunities, this thesis contributes to a deeper understanding of how to navigate the future of critical coastal infrastructure in the face of growing climate risks.
