The zoning policies that planners introduced to create vibrant and resilient mixed-use neighbourhoods have had the opposite effect, as services and residential developments crowd out light industry.
Can cities emerging from lockdown find a healthier way to engage with tourism?

Infrastructure is often seen as the main way to reduce the impacts of climate-related disasters like floods and drought. But cities are complex systems with many factors affecting their resilience.
We can design parks, open space and public infrastructure to hold excess water when flood strikes. That means better control of where floodwater ends up, reducing the risk to lives and property.
The disasters have come one after another. While they may not be entirely preventable, we can take many practical steps tailored to local needs and conditions to reduce the impacts on our cities.
One of the successful outcomes of being part of 100 Resilient Cities is Living Melbourne: our metropolitan urban forest, a newly released strategy to increase vegetation cover in the city.

Melbourne and Sydney are members of 100 Resilient CIties, which the Rockefeller Foundation has said it will no longer fund. So what has the global network achieved? And what can we learn from this?
With flood risks projected to rise, it’s feared parts of Townsville and other cities will become “uninsurable”.

Amid fears that parts of Townsville and other Australian cities might become “uninsurable”, making urban areas more resilient and adaptable to flooding is becoming more urgent.
Cairns has lots of hard grey infrastructure but much less green infrastructure that would reduce the impacts of the city’s growth.

Urbanisation is the main reason for rising temperatures and water pollution, but receives little attention in discussions about the health of water streams, reefs and oceans.
Flooding in Sydney last week was the latest example of Australian cities’ lack of resilience to a more extreme climate.

Australia’s coastal settlements are highly exposed to the impacts of climate change. Climate-resilient urban landscapes that can cope with large amounts of water need to become the new normal.
Ghana has at least one one major flood disaster every year.

Taking this step may improve the quality of life for vulnerable people and reduce the amount of air conditioning they use, making their neighborhoods less prone to power outages.
Hurricane Harvey flooded one-third of Houston and displaced more then 30,000 people in the region.

After disasters, communities often push to rebuild as quickly as possible. A public health expert says they should aim higher and fix problems that exist pre-storm.
If more people live in the Adelaide Hills, they are more likely to be exposed to bushfires.

What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
The intensity of heavy downpours in Houston has increased dramatically since the 1950s, leading some people to argue the city’s disaster planning and infrastructure are not up-to-date.

It’s not just about rebuilding infrastructure after storms: Cities need to systematically rethink their knowledge systems which are at the heart of urban resilience.
A solar and battery-powered microgrid got San Juan’s Children’s Hospital quickly back online after Hurricane Maria.

Yes, Puerto Rico and any other storm-vulnerable location could benefit from on-site solar and battery backup, but it’s unrealistic to say these microgrids are enough to power the island.
Hurricane Harvey from the International Space Station on August 28.

Three atmospheric scientists from Texas say Hurricane Harvey shows how the country needs to adapt to the effects of climate change and cut carbon emissions.
It’s hard to see how a city can be good for all its people unless they are involved in its creation.

Developing principles to create cities that are good for all is not easy. Who decides what is good? And for whom? We desperately need a big and general public discussion about this.
The uniquely weak regulation of high-rise, high-density development exemplifies the market-driven growth of Australian cities.

Disaster preparations often focus on gear and logistics, but research in Japan after the 2011 earthquake and tsunami shows that strong social ties played a key role in helping communities rebound.
