9. Bangkok, Thailand

Bangkok is the commercial centre of Thailand and a major hub in Southeast Asia.

By 2030, Bangkok’s population is expected to have grown from 9.3m to 11m, an 18.2 per cent increase according to the United Nation’s World Urbanization Prospects. This is bad news for the city’s traffic problem — already known to be one of the world’s worst cities for congestion.

However, schemes like Bangkok250, which is aiming to dramatically improve the cities transport infrastructure by its 250th birthday in 2032. By then there is expected to be 226 stations stretching 226 kilometres around the capital.

Meanwhile, the city continues to draw the country’s resources. The World Bank reckons that over 70 percent of Thailand’s public expenditure in 2010 benefited Greater Bangkok, home to 17 percent of the country’s population.
