Summary
Almost 60% of the world’s population live in cities. And this trend is expected to continue - by 2050 nearly 7 of 10 people will live in urban environments.
Although more than 80% of global GDP is generated in cities, there are challenges: increasing carbon emissions and environmental pollution, traffic congestion and urban vulnerability, exposed by natural disasters such as floods and storms.
The creation of a digital twin - a digital representation of a real city, infrastructure or even a whole country - could help decision-makers simulate real situations, allowing them to make better decisions. Situations like floods and other extreme weather events.
We look into the technology and find out what the benefits and limitations are...
And the former foreign minister of Tuvalu, Simon Kofe, explains how climate change has forced his country to consider preserving their whole statehood and culture in the metaverse.
