Despite Beijing’s sponge city project, the capital was overwhelmed by recent floods with dozens dying and a new “sponge airport” shut down

Recent devastating floods in Beijing have put China’s drive to create “sponge cities” which can handle extreme rain to the test.

Since 2013, China has been trying to make cities like Beijing more flood-proof by replacing roads, pavements and rooftops with natural materials like soil that soak up water and by giving more space to water bodies like lakes to absorb stormwater.

But despite these measures, massive amounts of rainfall in recent weeks caused floods which killed at least 33 people, destroyed tens of thousands of homes and shut down the Chinese capital’s second busiest airport.

Experts told Climate Home the flooding shows the limited progress China has made on its plan to invest $1 trillion into sponge cities by 2030 – with the city still largely concrete. Sponge airport overwhelmed

Even new infrastructure, build with the sponge city concept in mind, could not cope with the rains.

Daxing airport opened a few months before the Covid-19 pandemic. Its builders described it as a “sponge airport” as it was equipped with plants on its roof, a huge wetland and an artificial lake the size of over 1,000 Olympic swimming pools.

Despite these measures, the runways flooded on July 30 and it had to cancel over 50 flights.

Waters diverted

The government tried to collect the rain in 155 reservoirs in the Hai River Basin, but the measure proved ineffective in controlling the deluge.

About 50 years ago, the basin –a natural sponge–was locked with embankments and reservoirs to manage the water flow.

In recent years though, these structures have made flooding worse as climate change has increased the frequency and intensity of extreme rainfall. These structures lead to overflow, collapse and the authorities have blown them up to ease flooding.

Reuters reported that flood waters locked in reservoirs were diverted to low-lying populated land in Zhuozhuo, a small city around 80km from Beijing, to flush out the stormwater from the country’s national capital.

Residents of Zhuozhou were angry at the government’s response, Reuters reported. The government reacted by shutting down criticism on social media. More work needed

Experts argued that these problems show that, rather than abandoning the sponge city project, China and Beijing need to double down and make them better.

Kongjian Yu is the founder of Turenscape, a company involved in the project. He said that just “maybe 1% or 10%” of the city has been converted to a sponge city.

The government’s target is 20% by 2030. “We have a long way to go,” he said.

Yu added that sponge cities are worth doing not just because they control floods but for managing droughts and refilling groundwater supplies too.

Tony Wong, professor of sustainable development at Monash University, said that progress was always going to be slow as “it takes a long time and a lot of money” to convert a city like Beijing, with lots of people and concrete buildings crammed into a small area, into a sponge city.

More work is needed, says Wong, because Beijing and many other cities lack effective urban planning, and there is no provision for a safe channeling of extreme floodwater.

“What the city needs is the inclusion of green corridors, just like Singapore – another high-density city- has done to transport excess stormwater into low-lying areas to prevent loss of lives and property.”

If China pulls this off it could become an example for many developing countries with high-density cities struggling to control urban flooding, added Wong.

Here’s a summer story you never knew you needed: an 1895 article by Eugene Debs waxing poetic about bicycles, which he said would “liberate millions” and bring “the enrapturing panorama of nature” to all.

The mission of the bicycle is greatly underrated. Human ingenuity, in evolving the bicycle, has given man a mighty boon. It is to play a great part in the world’s affairs. It is to liberate millions from the thralldom of foul atmosphere, squalid and filthy apartments, and all the multiplicity of debauching and demoralizing conditions that make the lives of workingmen and women in manufacturing and commercial centers a continuous curse. It is to be an important factor in depopulating cities and building up the country.

It will be a mighty leveler upward and downward. The bicycle will attack the fabulous value of city real estate, distribute population, lower rent, close up the tenement den, and extinguish the sweatshop hell. It will free the inhabitants of cities from the fetid odors their overcrowded conditions generate and pour a perpetual flood of fresh air upon the race. As a matter of course working people will have them and the man who trudges to his daily toil will be an object for a relief commission.

The limits of an interview will admit only the merest glimpse of the possibilities of the bicycle. The great health-giving advantages of fresh air and exercise, will by the fiat of the bicycle, be the heritage of the race. The bicycle, not the medical profession, will triumph over disease. The wheel is on the trail of Consumption and will overtake and vanquish the remorseless destroyer. Men and women and children will all ride the bicycle and the enrapturing panorama of nature will no longer be forbidden glories to most of the race.

Of course, the bicycle is yet in embryo. The wheel of the future will revolve to suit man’s fancy and the variety, design, and capacity will be practically without limit. And when monopoly and special privilege are abolished, the bicycle may be purchased for a song and will be within the reach of all. The world will yet revolve on wheels.

JUST ONE MORE LANE BRO

Yet the constant risk of losing top talent has been enough to make companies reconsider their strict RTO mandates. Research has shown that companies that put pressure on employees to return to the office are more likely to experience turnover issues than those that don't.

Companies that have mandated a strict return to the office three days a week without first seeking employee input are experiencing the most angst, Kacher adds.

"They're the ones struggling with retention and recruitment," she says. "Some of the companies I work with have even scaled back the number of in-office days they're requiring in response to employee backlash."

‘Lahaina is not for sale’: Maui wildfire survivor to real estate developers

Archive hasn't been working for me lately but maybe someone in the comments can help.

As many as 10 Cruise driverless cars stopped working in San Francisco’s North Beach on Friday night, causing traffic to back up and leaving some questioning the decision of state regulators a day earlier to approve the expanded use of robotaxis in the city.

The autonomous vehicles appeared to be stopped in the middle of Grant Avenue, according to social media posts, with hazards on, blocking other cars from moving.

In a response to the incident, Cruise said the backup was caused by “wireless connectivity issues” that immobilized the driverless cars. San Francisco police confirmed that the cell connectivity issues were caused by the large number of people at the nearby Outside Lands music festival overtaxing the system.

“We are actively investigating and working on solutions to prevent this from happening again and apologize to those impacted,” Cruise said in a statement.

According to a text message exchange between San Francisco Supervisor Aaron Peskin and a Cruise government affairs manager reviewed by the Chronicle, the cell connectivity affected the company’s remote ability to reroute the cell-connected cars. According to Peskin, approximately 10 cars stalled at the intersection.

. . .

Transportation and fire officials told state regulators that the spike in robotaxi activity in recent months coincided with disruptive incidents, such as unplanned stops and erratic driving. They warned that such disruptions were likely to occur more often as the companies expanded service.

The road that the cars were paralyzed on was a “tiny street,” Peskin said, and there would have been no way for emergency vehicles to get through had there been an emergency.

“The irony is that this happened the night after the CPUC irresponsibly gave them the green light for unlimited vehicles over the city’s objections,” Peskin said.

The CPUC’s approval did not include a cap on fleet sizes, and Cruise and Waymo are not required to report to state regulators how many driverless taxis they operate in the city.

Don't go to that url, it's anti-cycling propaganda

It's a red flag with a steam train on it. How cool is that?

The picture is from a recent visit to a railway museum where they had an exhibit about the cold war. Being written by western libs the text next to the flag talked about how civil defence at places like the railway workshops was complicated when "everybody didn't agree on who the enemy was" and called the communists a "fifth column". Apparently, as all workers had to take part in civil defence still and know about plans in case of war, authorities were worried that the large communist presence at the workshop meant that they would tell the USSR about the plans or use their knowledge to sabotage the railways in case of war.
