Climate Change Risk and Adaptation
Central Otago faces drought and alpine hazard risk; Dunedin coastal flooding and storm surge risk; Wakatipu basin extreme weather; region-wide agricultural adaptation pressure.
Overview
Central Otago faces drought and alpine hazard risk; Dunedin coastal flooding and storm surge risk; Wakatipu basin extreme weather; region-wide agricultural adaptation pressure.
Structural drivers
Climate Change Intensity. Climate change accelerates; impacts on water, temperature, extreme events.
Solution camps
A number of distinct positions recur in the policy debate on this issue. Each is defensible on its own terms; none is obviously correct.
Climate Change Adaptation Framework. Region-wide climate adaptation planning and investment reduces climate risk. Key moves include Climate risk assessment and adaptation planning; Infrastructure climate resilience investment; Sector-specific adaptation pathways. The main tensions are: Upfront investment cost; Uncertainty in climate impacts.

Central Otago Drought and Irrigation Stress
Central Otago is NZ’s driest region; climate change extends dry season; irrigation demand and environmental flow conflicts intensify.
Overview
Central Otago is NZ’s driest region; climate change extends dry season; irrigation demand and environmental flow conflicts intensify.
Structural drivers
Central Otago Aridity and Drought Frequency. Central Otago NZ’s driest region; climate change extends dry season.
Solution camps
A number of distinct positions recur in the policy debate on this issue. Each is defensible on its own terms; none is obviously correct.
Water Security and Drought Adaptation. Diversified water sources, efficiency, and demand management ensure Central Otago drought resilience. Key moves include Develop groundwater and recycled water sources; Irrigation shift to drought-resistant crops; Water storage and catchment management. The main tensions are: High infrastructure costs; technology uncertainty; Farmer adoption barriers.

Alpine Hazards: Avalanche and Glacial Lake Hazards
Queenstown-Lakes faces avalanche risk in ski areas and transport corridors; glacial lake outburst flood potential in Fiordland headwaters.
Overview
Queenstown-Lakes faces avalanche risk in ski areas and transport corridors; glacial lake outburst flood potential in Fiordland headwaters.
Structural drivers
Alpine Snowpack and Glacier Decline. Otago alps losing glaciers and snowpack; impacts hydro supply, water availability, avalanche risk.
Solution camps
A number of distinct positions recur in the policy debate on this issue. Each is defensible on its own terms; none is obviously correct.
Alpine Hazard Management and Warning Systems. Avalanche forecasting, GLOF monitoring, and infrastructure resilience reduce alpine hazard impacts. Key moves include Avalanche forecasting and control program; GLOF monitoring for Fiordland lakes; Hazard-resilient infrastructure design for SH6. The main tensions are: High operational costs; technical uncertainty; Risk tolerance and road closure decisions.

Dunedin Coastal Flood and Storm Surge Risk
Dunedin CBD and Port Chalmers face sea level rise and extreme storm surge risk; earthquake and tsunami risk from Hikurangi Subduction Zone.
Overview
Dunedin CBD and Port Chalmers face sea level rise and extreme storm surge risk; earthquake and tsunami risk from Hikurangi Subduction Zone.
Structural drivers
Sea Level Rise and Storm Surge Risk. Dunedin and Port Chalmers face 0.5–1.0m sea level rise by 2100; storm surge and tsunami risk.
Solution camps
A number of distinct positions recur in the policy debate on this issue. Each is defensible on its own terms; none is obviously correct.
Dunedin Coastal Adaptation and Managed Retreat. Seawalls, nature-based solutions, and managed retreat protect Dunedin from sea-level rise. Key moves include Dunedin CBD seawall and stormwater upgrade; Mangrove and salt marsh restoration; Managed retreat policy for Port Chalmers. The main tensions are: High capital cost; long-term commitment required; Tension between protection and retreat approaches.
