Easing lockdowns around the world present an opportunity to go back to the drawing board for many economies. In Asia, densely packed urban centers are a good place to start. The trick for planners will be to minimize disease outbreaks without quashing the promise of employment that has made cities a magnet.

By 2025, the world will have 37 megacities — defined as having at least 10 million people — and as many as 20 of them will be in Asia. Two-thirds of the region’s population will be living in urban areas by 2050, compared with 20 percent in 1970, according to the Asian Development Bank. Bustling metropolises have become a symbol of rapid growth across the continent, which has reached a level of urbanization in less than a century that took more than twice as long in other parts of the world.

For decades, this transition was a one-way ticket to economic boom. With the coronavirus outbreak, however, we’ve seen cities become hotbeds of infection, where vast concentrations of wealth can become a liability when businesses grind to a halt. But while de-clogging seems like a good idea on paper, is it desirable or even feasible? Working remotely from the suburbs sounds great if you live in a congested downtown district, confined to four walls and a small bathroom with screaming kids. The reality in many rural areas, however, is poor infrastructure, subpar schools and scarce medical clinics, not to mention limited delivery options.
