As the article notes:
“Chengdu made the headlines in Britain late last year when it exported two pandas to Scotland, and it is developing a reputation as the centre of Sichuan’s prized cuisine. But few in the west have paid much attention to the astonishing rise of Chengdu, despite a population (including its rural hinterland) of more than 14 million and its evident economic power and growing sense of self-confidence. Few have heard much either of cities like Ghaziabad, Surat or Faridabad in India, or of Toluca in Mexico, Palembang in Indonesia or Chittagong, the Bangladeshi port. Or of Beihai, another Chinese city on the northern coast. But this is likely to change. Each of these cities is among the fastest-growing settlements in the world. Their cumulative growth is set to usher in a new era of city living, changing the face of the planet. Beihai, which already has 1.3 million inhabitants, is set to double its population in seven years. The municipality of Chengdu will reach 20 million. Ghaziabad, now itself part of the urban sprawl of the Indian capital Delhi, is already home to nearly four million people.
Crucially, though experts estimate that the number of megacities of more than 10 million inhabitants will double over the next 10 to 20 years, it is these less well-known cities, particularly in south and east Asia, that will see the biggest growth. Predicting what the new era will bring is taxing economists, senior businessmen, security experts and strategists across the world.
Optimists see a new network of powerful, stable and prosperous city states, each bigger than many small countries, where the benefits of urban living, the relative ease of delivering basic services compared to rural zones and new civic identities combine to raise living standards for billions. Pessimists see the opposite: a dystopic future where huge numbers of people fight over scarce resources in sprawling, divided, anarchic “non-communities” ravaged by disease and violence.
Nowhere is this more evident than in India, where years of underinvestment, chaotic development and rapid population growth have combined with poor governance and outdated financial systems to threaten an urban disaster.”
