Summary

The Coromandel Peninsula in New Zealand has 400 km of coastline and 90% of its population lives in the coastal zone. Following a 2018 storm, Thames Coromandel District Council decided to establish a framework for the management and reduction of risks to people, property, the environment and tāonga associated with coastal hazards. To this end, Thames Coromandel District Council (TCDC) developed 138 Coastal Adaptation pathways, one for each unique stretch of the Coromandel Peninsula’s shoreline, to address near-term issues while considering how local communities and hapu may need to adapt in the long-term. The definition of these pathways was enabled by a community-led journey based on locals’ values and risk appetites.

Actions

The project consisted in the development of Coastal Adaptation Pathways (CAPs) that address immediate, short- and medium-term issues, considering how communities may need to adapt in the longer term. 

The CAPs follow the Dynamic Adaptive Policy Pathways (DAPP) approach, which recognises that climate change-related coastal hazards are not certain and difficult to predict. Consequently, the pathways developed are intended to be flexible and designed to be dynamic (or adapted). If the predicted hazards do not occur, or do not occur as predicted, the pathway can be revised and actions (such as protect or retreat) may not need to be taken. The challenge relates to not acting too early (and investing to mitigate risks that are not realised) or too late.

In total, 138 CAPs, one for each unique stretch of the Coromandel Peninsula’s shoreline, were produced. CAPs develop tailored, flexible solutions to reduce the risk from coastal hazards to an acceptable or tolerable level; and to ensure the long-term sustainability and resilience of the Coromandel’s coast communities for the next 100 years. By their nature, the pathways will require review as new information becomes available, circumstances change or triggers for action are met. 

Important community engagement activities were conducted, including over 100 meetings. The project team worked with Coastal Panels to define coastal assets, coastal hazards, and to integrate local values to prioritise areas of action and design the CAPs. Panel members were nominated representatives from Mana Whenua, Community Boards, community organisations, business and citizens, tasked with representing the views of their community. Broader forms of public consultation at key milestones were also conducted to enable Coastal Panels to justify, clarify, and revise recommendations in response to public feedback.

Ultimately the 138 CAPs  build on the aspirations and concerns of TCDC’s communities and the principles of kaitiakitanga – the ethic and practice of safeguarding the natural environment and sustaining its resources, on which people depend.

Outcomes

In September 2022, TCDC adopted 138 adaptation pathways,  specific to the aspirations and concerns of TCDC’s communities and the principles of kaitiakitanga. 

Key outputs for each of the 138 CAPs have been integrated in i-reports, and an interactive Map Viewer has been created to enable all community members to access information about predicted coastal erosion and coastal flooding.

TCDC has already received the 2023 national award for environmental leadership for this project from Taitura (Local Government Professionals Aotearoa). In addition, the project has won the prestigious Terry Healy Project Award at the New Zealand Coastal Society (NZCS) conference in Wellington for its “significant contribution to New Zealand’s coastal and marine environment”.

Since the pathways are intended to be flexible and dynamic (or adapted) – so they can be revised if the predicted hazards do not occur, or not as predicted – the challenge relates to not acting too early (and investing to mitigate risks that are not realised) or too late.
