Critics have suggested that the concept could cause gentrification by further concentratingwealth in the most accessible and convenient districts. The desirability of "15-minute" neighborhoods may, in turn, result in home prices that exclude low-income and marginalizedcommunities.
But the Covid-19 pandemic has seen growing interest in the concept. With people around theworld working from home and avoiding public transport, urban planners have begunpedestrianizing streets and reimagining how cities manage dense populations.
Writing in the academic journal Smart Cities earlier this year, Moreno said, "The emergenceof this pandemic exposed the vulnerability of cities ... and the need for a radical re-thinking, where innovative measures need to be tailored to ensure that urban residents areable to cope and continue with their basic activities, including cultural ones, to ensure that citiesremain both resilient and livable in the short and long terms."
