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.

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 invite NZ-based researchers, industry, stakeholders and Māori to submit expressions of Interest (EoIs) for research projects that will contribute directly to building a ‘blue economy’ in Aotearoa.
Last week (3–5 March), schoolchildren from across New Zealand travelled with LEARNZ and the Sustainable Seas Challenge to discover what's threatening mussels/kuku or kūtai, a taonga species, in Ōhiwa Harbour, and how science and mātauranga Māori are being combined by local kaitiaki to understand – and address – the problem.
