Our changing climate is already impacting the Otago community.
The impacts from Otago's changing climate are varied, and the entire region is sure to experience more changes that are yet to come. To better understand the impacts of climate change and associated risks and opportunities for the region, we have carried out the Otago Climate Change Risk Assessment (OCCRA).
The Otago Climate Change Risk Assessment (OCCRA) provides us with an understanding of the threats posed to our region by climate change. Using this knowledge, we can collectively respond to climate change, as a region.
Local communities, institutions, businesses, government bodies, and other organisations can work together to proactively approach climate change by making informed and responsible decisions.

Risks |
Local vs central government influence |
|
G1 |
Risk that existing planning, decision making, and legislative frameworks are inadequate for responding to long-term climate change risks and result in maladaptive responses, and potential liability. |
Combination of local and central influence |
G2 |
Risk of local authorities lacking capacity to effectively respond to climate change. |
Local direct influence |
G3 |
Risk that the national, regional and local governance/institutional structures for managing climate change are inadequate. |
Combination of local and central influence |
G4 |
Risk that a low level of community awareness and engagement hinders communication of climate risk and uncertainty, and leads to de-prioritisation. |
Local direct influence |
G5 |
Risk that climate change will result in increasing damage costs, with insufficient financing for adaptation and risk reduction. |
Combination of local and central influence |
G6 |
Risk that public services will be impacted by climate change. |
