Urban public health is currently in the spotlight as city populations struggle to deal with the threat of COVID-19. As lockdown measures take their toll on urban communities, city dwellers have been forced to see their cities through new eyes, and the results have been worrying.

A study from the UN has found that 68% of the global population will be living in cities and metropolitan areas by 2050. However, many researchers believe that the stats will likely be far higher, and further estimates suggest that up to 90% of the planet’s population could be living in megacities within the next 30 years.

The current coronavirus pandemic has proven that cities will need to adapt if they want to nurture healthier, happier, and safer populations. Urban public health will need to evolve to cater for denser populations, and the potential hazards that go along with it.

The term “smart city” has a different meaning for different people. For most, it conjures up a vision of a technologically-advanced metropolis, where citizens rely on smart gadgets to go about their daily lives. For others, the smart city concept describes government initiatives based on big data, technology and intelligent processes that improve the quality of life of a city’s residents. These aren’t incorrect definitions, they’re just two sides of a multi-faceted approach to urban development.

Technology and data are essential building blocks for creating a smart city. But it’s the city’s residents that can help enact the biggest changes. By introducing projects that focus on improving the lives of individuals and communities, smart cities can begin to grow on their own.

One of the most talked-about methods of transforming a city into a smarter city is by introducing 15-minute neighborhoods. More commonly known as a 15-minute city, or even a 20-minute city, these strategies focus on improving the lives of residents by making the city more accessible to everyone.

“There’s a positive aspect of this horror,” the deputy mayor of Paris, Jean-Louis Missika, told the Washington Post. “Never has the city been less polluted. Parisians have much appreciated it, and I think there will be strong changes in the behaviour of people, in terms of movement.” This is a sentiment shared by many leaders across the globe.

Despite the hardships caused by the spread of Covid-19, the current situation presents a unique opportunity. Now is an ideal time to revolutionize the way we live in urban environments.

It’s a quiet revolution that has already begun.
