University Plants Asia’s Biggest Rooftop Farm in Thailand

“Thailand is an agricultural society, but in the cities we are so cut off from the source of our food. With rooftop farms, we can also improve urban food security,”



Bangkok’s Thammasat University, one of the oldest in Thailand, has a new claim to fame, Asia’s largest urban rooftop farm.

The 75,000 sq ft space mimics rice terraces in northern Thailand. It can help also curb some of the impacts of climate change, such as frequent flooding, said Kotchakorn Voraakhom, the landscape architect behind the project.

“We tend to make a distinction between buildings and green spaces. However green spaces can be part of building design in cities like Bangkok which has few green spaces,” said Kotchakorn, the chief executive and founder of Landprocess.

“Rooftops are usually under utilized but they can be green spaces that reduce the urban heat-island effect. The environmental impacts of buildings and land use, and also feed people,” she said. The rooftop farm opened on Tuesday.

Rooftop Farm on the Flood Plans of Chao Phraya River

Bangkok, built on the floodplains of the Chao Phraya River, is forecast by climate experts to sink by more than 1 centimeter (0.4 inches) annually and become one of the urban areas to be hit hardest by extreme weather conditions in the coming years.

Nearly 40% of the Thai capital may become flooded each year by 2030 due to more intense rainfall, according to the World Bank estimates.

Flooding in many parts of Bangkok is already common during the annual monsoon. The rains in 2011 brought the worst floods in decades, putting a fifth of the city under water.

It was after that disaster that Kotchakorn began thinking more about climate-resilient green spaces.

She recently designed Bangkok’s first new public park in decades – a 4-hectare (11-acre) space at Chulalongkorn University that can hold up to 1  million gallons of rainwater.

The rooftop farm at Thammasat University in Rangsit, about 40 km (25 miles) from Bangkok’s city center, is open to anyone who wishes to grow rice, vegetables and herbs, said Prinya Thaewanarumitkul, a vice vector at the university.

Rooftop Farm will improve urban food security

“Thailand is an agricultural society, but in the cities we are so cut off from the source of our food. With rooftop farms, we can also improve urban food security,” he told Reuters.

With more than two-thirds of the world’s population forecast to live in cities by 2050. This is according to the United Nations, urban agriculture could be critical.

Urban farms could supply almost the entire recommended consumption of vegetables for city dwellers. Also cutting food waste and reducing emissions from transportation of agricultural products.

With space at a premium, cities from Paris to Singapore are adding farms atop malls and conference halls.

As climate risks increase, rooftop farms will no longer be a novelty, said Kotchakorn. He was named last month on Time magazine’s inaugural 100 Next list of rising stars.

“There are limited opportunities to create new green spaces in cities,” she told the Thomson Reuters Foundation.

“Urban rooftop farms are an easy and effective climate solution, and should be the norm.”
