Basuki “Ahok” Tjahaja Purnama’s two-year prison term on trumped-up blasphemy charges will give the suspended Jakarta governor plenty of time to consider his legacy. One recently completed civic improvement under his tenure saw the brothels in Kalijodo, a major red-light district, bulldozed and replaced with a riverside park and recreational centre.

It’s a boon for the law-abiding residents who have been allowed to stay in the neighbourhood. But for the rest of the city, this urban regeneration presupposes that a nationwide clampdown on the world’s oldest profession will work – and Kalijodo’s former tenants won’t simply set up shop elsewhere.

Shanghai is China’s gateway to the world but the city’s international airport can’t seem to fix its biggest shortcoming: flight delays. Shanghai Pudong International Airport isn’t to blame though: China’s military is. It uses the skies above the airport for training, particularly during the summer months, and this can ground flights and prevent landings for an entire day. As Chinese president Xi Jinping streamlines his country’s military and pushes for economic liberalisation everywhere else he would be wise to consider giving the commercial aviation industry more control over Shanghai’s airspace.

When he was elected mayor of Shibuya Ward in 2015, Ken Hasebe said that he’d make childcare a priority. With more than 300 children waiting for a nursery place in Shibuya (and more than 8,000 across Tokyo), the need was clear, particularly given the government’s desire to get more women back into work.

Hasebe has made good on his promise: this October a new nursery will open in Yoyogi Park, one of Tokyo’s biggest green spaces. Thanks to a special rule that makes it possible to open a nursery in a city park, Hasebe’s team was granted permission to open the first park nursery in Shibuya. It’s heartening to know that campaign pledges can lead to real change.
