Reducing the risk from natural hazards

The Waitaha/Canterbury region faces a variety of natural hazards that significantly impact infrastructure, communities, and ecosystems – many of which are worsened by climate change.

Drivers for change

New hazards have arisen from changes in the environment and climate as well as how we interact with our environment. We are already experiencing more extreme weather events more frequently. Other imminent hazards, such as a rupture of the Alpine Fault, become more likely as time passes.

The needs of our communities are also changing in a way that potentially increases our exposure to hazards.

What we heard

• Identify areas at highest risk and make a plan to protect them better or to relocate.
• Don’t build in areas at high risk from fire, flood and earthquakes.
• Move or upgrade critical infrastructure to withstand extreme events.

What we can influence

• We can be more directive and precautionary about where development should be avoided.
• For areas that may need to relocate we can consider where they may need to move to, engage with communities, local authorities and government agencies on how and when that might occur, and ensure enabling policies are in place to support managed relocation.
• We can also support and encourage the restoration or creation of natural barriers such as wetlands and dunes.
