Novel risk assessment tools for ecosystem-based management
We are reviewing new methods to help assess and manage risks to Aotearoa New Zealand’s marine ecosystems.

Duration: Dec 2017 – September 2019
To manage marine ecosystems sustainably, decision-makers need to be able to predict how they will respond to changes or threats. Risk assessment can help by identifying possible changes caused by an activity, the environmental and social consequences, and how likely each outcome is to occur.
We are reviewing new methods for risk assessment to see if they can be applied to ecosystem-based management of marine areas. We are focussing primarily on methods that deal with uncertainty. We are looking for the best methods to assess and manage risks to the marine environment from changing patterns of human use. This is challenging as multiple stressors from human activities can interact, leading to significant consequences when the ecosystem can no longer cope, and a tipping point is reached.
We are also exploring how mātauranga Māori can be incorporated into risk assessments and management.
Our research aims to enable New Zealanders to participate in developing plausible threat scenarios and to evaluate the risks associated with them. We want decisions about future risks to be informed by the best available information and methods.
Our research will help to optimise methods for choosing among a set of alternative policy strategies, evaluate combinations of stressors, and determine management strategies that are most ‘robust’ to threats. The findings of our research will be useful for decision-makers in the marine environment, including central and regional government, and Māori.

We’ve developed an interactive map that shows the locations and key information of all our research projects. The aim is to help connect people with the research happening in their community.
Julie Hall, Director: "It is deeply concerning that the state of our marine environment has not improved in the last three years. Resilient coasts and oceans are essential to New Zealanders' health and wealth, so urgent action is needed to address the decline. There is a growing need for ecosystem-based management (EBM) to holistically manage risk and sustain Aotearoa's coasts and oceans. This is even more important given the ongoing impacts of climate change."
