Deep dives
Digital Twin Cities: Mitigating Climate Change
Digital twin cities are virtual representations of physical cities used to address climate change. These digital twins can help cities understand the impact of climate change and plan for future scenarios. Singapore, for example, has created a digital twin to study the effects of rising sea levels and simulate urban and event planning. The digital twin allows for visualizing the potential consequences of climate change with increased water levels and helps in making decisions for flood risk mitigation. Similar efforts are being made in the UK, where a digital twin called Credo focuses on key infrastructure networks to protect critical assets during extreme weather events.
Tuvalu's Digital Twin: Preserving Culture in the Face of Climate Change
Tuvalu, a low-lying Pacific island nation facing the threat of extinction due to climate change, is creating a digital twin to preserve its essence and culture. The digital twin serves as a blueprint of the islands, providing data on sea level rise and future projections. It also allows for the digitization of aspects of Tuvalu's culture to share and teach others about their heritage. By creating a digital nation within the metaverse, Tuvalu aims to continue existing as a state even without a physical territory. This innovative approach highlights the importance of preserving culture and the urgency of collective global action to combat climate change.
The Potential of Digital Twin Cities in Climate Action
Connected digital twin cities, integrated ecosystems combining physical, digital, and human systems, have the potential to play a transformative role in tackling climate change. By leveraging data and creating interconnected systems, decision-makers can make more informed choices to reduce carbon impact. The availability of real-time information through digital twin cities empowers individuals and governments to take decisive climate action. It enables better understanding of energy efficiency initiatives, resilience planning, and data-driven decision-making. Utilizing connected digital twin cities can lead us closer to achieving urgent climate change goals and a sustainable future.
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.
