Bangkok on track for more green spaces with park on old train line

Sky park shows how space-starved cities can repurpose unused land for green spaces that can ease the effects of climate change

By Rina Chandran

The Phra Pok Klao Sky Park in Bangkok, which is scheduled to open later this month, connects neighbourhoods on either side of the Chao Phraya river and was built on an elevated rail line that lay unused for more than three decades.

“It is an example of how to repurpose an abandoned structure and increase green spaces in Bangkok through cost-effective design,” said Niramon Serisakul, director of Urban Design and Development Center, a consultancy that led the project.

“It may not be large, but it has outsized importance as a catalyst for urban regeneration, and can change the way people look at public spaces,” she said.

“The effects of climate change are being felt more, so we need more green spaces,” Asawin Kwanmuang, governor of the Bangkok Metropolitan Administration, said at a ceremony to plant trees ahead of the park’s opening.

“Our goal is to increase green space in Bangkok from about 6 square metres (65 sq ft) per person to 9 square metres per person. At the same time, we want to reduce the number of cars and make the city more walkable,” he told the Thomson Reuters Foundation.

The park, measuring 280 metres by 8 metres, makes it easier for residents to access nearby schools, markets and places of worship, said Niramon.

At the same time, we want to reduce the number of cars and make the city more walkable.

The goal is to replicate Paris’s “15-minute city”, where people can reach their destination within 15 minutes of walking, cycling or using mass transit, she said.

Bangkok’s new sky park can be a model for swathes of unused land under the city’s expressways, said landscape architect Kotchakorn Voraakhom, who was involved in the project.

Parks and rooftop gardens can reduce air pollution and harmful emissions, and also limit flooding, said Kotchakorn, who has designed a rooftop farm and park that can retain water.

The impact of the COVID-19 crisis on clean energy progress

The Covid-19 pandemic is having a major impact on energy systems around the world, curbing investments and threatening to slow the expansion of key clean energy technologies. Looking at all the data so far on how the Covid-19 crisis is impacting clean energy transitions, 10 key themes emerge – and this article examines each of them.

 

CO2 emissions: Short-term shock does not guarantee sustained decline

The global pandemic has imposed unprecedented constraints on social and economic activity – particularly on mobility – with severe impacts on energy use. Global energy demand is expected to contract by 6% in 2020, the largest drop in more than 70 years. Global CO2 emissions are expected to decline 8% in 2020, falling to their lowest level since 2010. This drop in emissions is no cause for celebration, since it is the result of a global health crisis, surging unemployment and tremendous economic hardship. Even the flattening of CO2 emissions during the robust economic growth of 2019 was far from the annual 6% reduction required in the IEA’s Sustainable Development Scenario (SDS), which is fully aligned with climate goals of the Paris Agreement.

 

Furthermore, after past economic downturns, emissions recovered rapidly as economies regained their footing. While the current crisis may have accelerated some structural changes – such as the decline of coal in Europe – the temporary drop in energy use resulting from mass restrictions on movement is far from sufficient. Smart and ambitious government policies will be needed to bring about the kind of sustained structural adjustments needed across a full range of sectors to achieve long-term climate goals.

 

Renewables have been resilient so far, but government support remains key

Renewable power sources have so far demonstrated resilience in the face of the Covid-19 crisis. The share of renewables in global electricity supply reached nearly 28% in the first quarter of 2020, up from 26% during the same period in 2019. 

Despite this resilience, renewables’ growth is expected to slow down in 2020. The world is set to add only 167 gigawatts (GW) of renewable power capacity this year – 13% less than in 2019. This decline reflects delays in construction due to supply chain disruptions, lockdown measures and social distancing guidelines, as well as emerging financing challenges. The majority of delayed utility-scale projects are expected to come online in 2021, but installations of rooftop solar PV for businesses and households may continue to be depressed in the medium term without strong government support.

Beyond electricity, renewables have been less resilient. Transport biofuel production is expected to contract by 13% in 2020 – its first drop in two decades. Renewable heat consumption is also likely to decline in 2020, mainly due to lower activity in the industrial sector. Adding to these difficulties, low oil and gas prices are making biofuels and renewable heat technologies less cost-competitive.

Governments have an unprecedented opportunity to accelerate clean energy transitions by making investment in renewables a key part of stimulus packages to reinvigorate their economies. Investing in renewables, whose costs continue to fall rapidly, can stimulate job creation and economic development while reducing emissions and fostering further innovation.
