With their heads in the clouds and their hands in the soil, a group of office workers are busy harvesting the fruits of their labor on the roof of a Hong Kong skyscraper.
Invisible to those below, a sprawling garden of radishes, carrots and rhubarb is flourishing at the top of the 150m tall Bank of America tower, a stark and colorful contrast to the monotone shades of concrete, steel and glass of the territory’s financial district.
The farm is among more than 60 that have sprouted across the space-starved territory since 2015 — on decommissioned helipads, shopping mall rooftops and public terraces — thanks to initiatives like Rooftop Republic, a local social enterprise that promotes urban farming.

Cofounder Andrew Tsui (徐伽) sees the rooftop farms as a way for people to reconnect with how sustainable food can be produced in what he calls the current “instant-noodle city lifestyle” that sees so much waste.
“What we are looking at is really how to identify underutilized spaces among the city and mobilize the citizens, the people, to learn about food,” the 43-year-old told reporters during a blustery site inspection of the skyscraper’s garden.
Tsui believes Hong Kongers need to re-establish a relationship with what they eat that has been broken “since we started outsourcing our food and relying so much on industrialized production.”
According to government statistics, Hong Kong throws out about 3,500 tonnes of food waste a day — the equivalent weight of 250 double-decker buses. Less than one-quarter is recycled.
About 90 percent of the food eaten by the territory’s 7.5 million inhabitants is imported, mostly from mainland China.
However, while Hong Kong is one of the most densely packed places on Earth, there is still considerable space to grow food locally.
Tsui said about 7 million square meters of farmable area is currently cultivated.
However, more than 6 million square meters on the territory’s rooftops remain unused.
“So we could have the potential of doubling the supply of land for growing food,” he said.
“The challenge for us is to design urban farming as a lifestyle to integrate into our daily life,” he added. “And the first step for that, of course, is to be accessible.”
To incorporate urban farms into the blueprints for office buildings, Rooftop Republic closely collaborates with architects, developers and property managers.
Major companies are signing up. As well as the Bank of America garden, financed by property consultancy giant Jones Lang LaSalle Inc, Singaporean banking giant DBS Bank Ltd (星展銀行) has partnered with Rooftop Republic to set up an academy that runs workshops for beginners as well as professional courses.
“In Hong Kong, most of the people focus on the commercial value of the properties. But we want to promote the concept of sustainability,” said Eric Lau, the group’s senior director of property management.
Urban farmers say the projects also help build community spirit among those who cultivate the crops.
After retiring from the public service, Lai Yee-man said she turned to farming to connect with nature and her neighbors.
The 60-year-old initially learned techniques and tricks from professionals to develop her farming plot in the New Territories region of Hong Kong — a rural area close to the border with mainland China.
Now she is passing on her knowledge to fellow residents working the Sky Garden, a 1,200m2 facility on top of a mall.
There residents cultivate edible flowers and fruit trees, and can attend lifestyle classes like mindful gardening.
“People attach greater importance to their health now, they will buy organic food,” Lai said. “Here, we teach them not to waste ... and to cherish their food,” she said, adding that the majority of what the mall farm grows goes to local food banks.
Tsui recognizes that few young Hong Kongers have an interest in learning how to grow food.
However, younger people are often concerned about the environment and climate change, so the opportunity to generate enthusiasm is there for the taking.
“If coding is the skill set to learn for the 21st century, growing your own food is a necessary new skill that we all need to learn to ensure a regenerative and green planet,” he said.
TECH BOOST: New TSMC wafer fabs in Arizona are to dramatically improve US advanced chip production, a report by market research firm TrendForce said With Taiwan Semiconductor Manufacturing Co (TSMC, 台積電) pouring large funds into Arizona, the US is expected to see an improvement in its status to become the second-largest maker of advanced semiconductors in 2027, Taipei-based market researcher TrendForce Corp (集邦科技) said in a report last week. TrendForce estimates the US would account for a 21 percent share in the global advanced integrated circuit (IC) production market by 2027, sharply up from the current 9 percent, as TSMC is investing US$65 billion to build three wafer fabs in Arizona, the report said. TrendForce defined the advanced chipmaking processes as the 7-nanometer process or more
China’s Huawei Technologies Co (華為) plans to start mass-producing its most advanced artificial intelligence (AI) chip in the first quarter of next year, even as it struggles to make enough chips due to US restrictions, two people familiar with the matter said. The telecoms conglomerate has sent samples of the Ascend 910C — its newest chip, meant to rival those made by US chipmaker Nvidia Corp — to some technology firms and started taking orders, the sources told Reuters. The 910C is being made by top Chinese contract chipmaker Semiconductor Manufacturing International Corp (SMIC, 中芯) on its N+2 process, but a lack
Who would not want a social media audience that grows without new content? During the three years she paused production of her short do-it-yourself (DIY) farmer’s lifestyle videos, Chinese vlogger Li Ziqi (李子柒), 34, has seen her YouTube subscribers increase to 20.2 million from about 14 million. While YouTube is banned in China, her fan base there — although not the size of YouTube’s MrBeast, who has 330 million subscribers — is close to 100 million across the country’s social media platforms Douyin (抖音), Sina Weibo (新浪微博) and Xiaohongshu (小紅書). When Li finally released new videos last week — ending what has
OPEN SCIENCE: International collaboration on math and science will persevere even if the incoming Trump administration imposes strict controls, Nvidia’s CEO said Nvidia Corp CEO Jensen Huang (黃仁勳) said on Saturday that global cooperation in technology would continue even if the incoming US administration imposes stricter export controls on advanced computing products. US president-elect Donald Trump, in his first term in office, imposed restrictions on the sale of US technology to China citing national security — a policy continued under US President Joe Biden. The curbs forced Nvidia, the world’s leading maker of chips used for artificial intelligence (AI) applications, to change its product lineup in China. The US chipmaking giant last week reported record-high quarterly revenue on the back of strong AI chip
