Tools for decision makers
Supporting decision making in a changing climate
As an island nation with high rainfall, flooding and sea level rise pose threats to economic and social activities on floodplains and at the coast. Decisions in such locations need to be adaptive, to recognise when thresholds may be crossed and to deal with changes before they happen. In this way, decision makers can avoid or reduce the consequent damage and costs.
The mission of the Deep South Challenge is to “enable New Zealanders to adapt, manage risk and thrive in a changing climate”. New and practical tools are needed to enable decision makers to respond appropriately to climate related impacts, to limit damage and costs to the nation and its communities. With uncertainty about the timing and magnitude of climate change impacts, local government and infrastructure providers in particular need new and adaptive decision-making tools that take into account changing risk profiles. The Dynamic Adaptive Pathways Planning (DAPP) approach is an assessment tool for developing adaptation options. It helps decision makers consider the conditions under which policies will fail to reduce risks, and provides stress-test options using plausible socioeconomic scenarios of the future.
The project is focussing on flood and sea level rise management, enabling decision makers to move, over time, towards sustainable pathways that are more climate resilient. This approach was first developed in the Netherlands, and follows on from the successful development and application of the DAPP approach with local and regional councils in New Zealand, led by Victoria University of Wellington with support from Ministry for the Environment.

The recent Edgecumbe floods saw raw sewage floating through the streets, making the clean-up extremely challenging. Over 300 homes in the district were damaged and six months later, 240 houses are still unliveable. Flood-proofing the town itself remains a distant goal.
The Deep South Challenge announces new research into who should bear the cost of our changing climate, and when.
All over New Zealand, from Haumoana to Westport, from Edgecumbe to the Kāpiti Coast, from Dunedin to Wellington City, homeowners and businesses are starting to feel the financial effects of climate change.
Susan Livengood is the Partnerships Director of the Deep South Challenge, and works within the Engagement programme – which tries to connect what’s happening in every programme of the challenge with both the broader public and with targeted individuals and organisations throughout New Zealand’s public and private sectors.
