A key measurement in the ND-GAIN vulnerability assessment is the strength of a country’s infrastructure in the face of disaster. In today’s hyperconnected world, it is physical infrastructure that has proved critical in delivering digital services that connect citizens to emergency services, protect assets and distribute resources to impacted areas.
In Singapore, surface water flooding and extreme heat present a risk to this infrastructure whereas Australia’s risks lie in bushfires and riverine flooding.3
To mitigate these risks, Singtel and Optus take a multipronged approach that is driven by climate modelling to predict risk up to the year 2100. Let’s look at the specifics:
Extreme heat
In preparation for extreme heat, Singtel will provide adequate cooling at exchanges to prevent functional failure from extreme heat. Onsite energy generation and batteries will also strengthen the resilience of energy supplies.3
Bushfires
In Australia, where bushfires occur, fire-resistant filters and new, concrete-based retaining walls will minimise the vulnerability of critical infrastructure. Much like the preparation for extreme heat, long-term adaptation includes renewable energy generation, battery storage and backup generators to strengthen energy resilience.4
Riverine flooding
Adaptive design for Controlled Environment Vaults (CEVs) will ensure they are resilient to riverine flooding. The height of CEV equipment will be raised3 and base stations will also be raised to at least 5m above sea level.5
Extreme weather events
Protecting physical infrastructure from other, unpredictable weather events can only happen alongside ongoing research with leaders in climate science. This allows for better prediction of localised events and more effective disaster response.
To further protect infrastructure in the long term, climate resilience is incorporated into business strategy. This ensures that double materiality [link to infographic pending upload] can be achieved and business continuity is not impacted.
