The Otago Regional Council (ORC) have initiated a climate change risk assessment across all of Otago to better understand the impacts of climate change and associated risks and opportunities.

Why are we doing this risk assessment

The purpose of this risk assessment is to provide an understanding of

  • potential changes to some climate variables
  • identify areas of risk in our region
  • qualify the vulnerability of these risk areas
  • consequences of the climate scenarios for these risk areas

Ultimately, we aim to get a prioritisation of the region's risks for further potential information gathering and assessment and the focus of adaptation plans.

How we came up with the short list of risks and their scores

The Territorial Authorities across the region worked with us to combine our knowledge and produce an initial list assessing climate change risk across the five value domains identified (as fits with the National Climate Change Risk Assessment Framework):

  1. Human
  2. Natural environment
  3. Built environment
  4. Economy
  5. Governance

A long-list of climate change risk elements were compiled based on the knowledge and expertise of participants and these were assessed for vulnerability and consequence based on the RCP 8.5 climate change projections for Otago (NIWA 2019 report).

For the built environment, natural environment, and economy domains, a full assessment was made combining vulnerability and consequence scores to generate a risk score. A short list of risks was created selecting those scores that were either major or extreme.

For the human and governance domains a simpler approach was utilised, a higher-level qualitative description of the risks was used to create the list. Climate change opportunities were also identified.

For more information on the methodology and risk assessment workshop summary, see relevant documents.

This page will be open for your feedback until 10 June.

We will then review your feedback and respond. This may involve clarifying some of your submissions or working together on reviewed scoring for some risk scores.

Thank you for taking the time to submit, we appreciate the crucial input you have provided.
