Risk management for Māori coastal assets

Coastal Māori farming communities are already affected by sea level rise. Erosion of the beach and even the collapse of some coastal infrastructure during storms is happening in several parts of the country. Effects such as flooding due to rising groundwater are subtler and more widespread. 

This project builds on the significant collective knowledge about climate change risks and opportunities built throughout 2015–17 in the rohe of Horowhenua– Kāpiti (see page 8). This second phase of our project aims to take another step towards change: co-developing Transition Action Plans that, given local conditions, will enable Māori communities throughout Aotearoa New Zealand to assess the risks and benefits of alternative coastal land use.

In the first phase of our project, we combined data about soil, floods, topography, river sedimentation and sea level rise to identify the most vulnerable areas of our coastal farms. We also used an interdisciplinary approach to identify indicators of change and staged strategies for adaptation. This second phase will examine physical processes such as future change in groundwater levels, and identify a wider range of options for managing wetlands and landscapes.

Although multiple reports have been produced about coastal erosion risks – including by local and regional councils – none have highlighted social engagement processes that could lead to effective community action. Our Māori-led interdisciplinary action research approach prioritises social engagement when considering how to respond to sea level rise and other climate change impacts.

Creating a climate-safe Dunedin through community-driven climate action

2018 may well be the year New Zealand gets serious about adapting to our changing climate. Last year, and the start of this one, gave all of us plenty of opportunities to experience a future in which creeping sea level rise and extreme weather – from drought to flood to surprise storm surges – make day-to-day life more precarious and more expensive.

Stormwater, wastewater and climate change: Impacts on our economy, environment, culture and society

In October 2017, the Deep South Challenge released a report into the state of the nation’s storm and waste water infrastructure, in the face of a changing climate. The report garnered significant media attention – not surprising given the infrastructure is currently valued at well over $20 billion.

The Deep South Challenge awards funding to investigate climate-resilient, high-value crops for the whānau of Omaio

The whānau of Omaio in the Bay of Plenty have joined forces with NIWA researchers to explore the viability of climate-resilient, high-value crops for the rohe. The group has won a $250,000 research grant under the Vision Mātauranga programme of the Deep South National Science Challenge to better understand Omaio’s changing climate and how it might support the community to create a local economy based around a high-value product like kiwi fruit.
