Asian cities most threatened by environmental risk
Companies operating and investing in Asian cities are going to face an increasingly stiff test to their resilience.
A global study of the world’s biggest cities finds Jakarta to be at the highest risk, thanks to high levels of air pollution coupled with risks of seismic activity and flooding. Of the 100 most threatened cities by environmental factors, 99 cities are in Asia, with 80 of them in the region’s powerhouses China and India.
According to the first instalment of [email protected] series, which ranks the world’s 576 largest urban centres on their exposure to a range of environmental and climate-related threats, 99 of the world’s 100 riskiest cities are in Asia, including 37 in China and 43 in India.
1.4 bn city dwellers facing high or extreme environmental risk
[email protected] data reveals Jakarta is the riskiest city, but across the globe 414 cities – with over 1.4 billion inhabitants – are deemed to be at high or extreme risk from a combination of pollution, dwindling water supplies, extreme heat stress, natural hazards and vulnerability to climate change.
With rising emissions driving weather-related risk and populations growing in many cities across the developing world, the risks to citizens, real assets, and commercial operations are only going to rise.
Indian cities on the environmental frontline
The global index, which draws on nine of our risk indices to evaluate the liveability, investment potential and operational risk landscape of cities with a population over 1 million, reveals that India has 13 of the world’s 20 highest risk locations.
The capital, Delhi, is rated as the second-highest risk city globally and is followed by the likes of Chennai (3rd), Agra (6th) and Kanpur (10th). Close behind are Jaipur (22nd), Lucknow (24th), Bengaluru (25th) and Mumbai (27th).
Pollution is the main threat to the health of the country’s huge urban populations, with Indian cities making up 19 of the 20 most at risk in our Air Quality Index. Noxious air caused almost one in five deaths in India in 2019, resulting in economic losses of USD36 billion; meanwhile, water pollution is responsible for almost USD9 billion in annual health costs and causes 400,000 deaths each year.
Jakarta worst-performing city in the ranking,
The worst-performing city in the ranking, Jakarta, is also plagued with dire air pollution, but compounding this are perennial threats from seismic activity and flooding. It is also subsiding at such a rate that Indonesia’s president, Joko Widodo, is seeking to relocate the capital.
A similar mix puts its Indonesian counterparts Surabaya and Bandung in 4th and 8th place respectively, while also contributing to Pakistan’s two most populous cities, Karachi (12th) and Lahore (15th), featuring in the top 20.
