Vietnam’s biggest city faces risk from floods by 2050

Ho Chi Minh City, Vietnam’s biggest metropolis, faces an increasing risk of flood disasters given rapid infrastructure expansion driven by economic growth, according to McKinsey Global Institute.
The chance of such events could increase five to 10 times by 2050, resulting in economic and infrastructural damage that could cost billions of dollars, according to a McKinsey report, dated April. The analysis is based on hydrological simulations, land-use maps, infrastructure databases and damage curves. Ho Chi Minh City, a historic flood area located some 1,000 miles south of the capital Hanoi, contributes about a quarter of the Vietnam’s gross domestic product. While the metropolis can cope with flood risks today that could hit 23% of its area, further urbanisation is raising the potential for land subsidence and an increase in sea levels.
