Cities are the manifestation of the cultural, economic and social acceleration that we have experienced in our modern history. According to the Sustainable Urbanization Policy Brief, urban centres currently occupy less than 5% of the world‘s landmass. Nevertheless they account for around 70% of both global energy consumption and greenhouse gas emission.
Urbanization is taking place at lower levels of economic development and the majority of future urban population growth will take place in small- to medium-sized urban areas in developing countries. Just three countries — India, China and Nigeria – together are expected to account for 37 per cent of the projected growth of the world‘s urban population between 2014 and 2050. India is projected to add 404 million urban dwellers, China 292 million and Nigeria 212 millions.
The number of mega-cities has nearly tripled since 1990; and by 2030, 41 urban agglomerations are projected to house at least 10 million inhabitants each. Tokyo is projected to remain the world‘s largest city in 2030 with 37 million inhabitants, followed closely by Delhi where the population is projected to rise swiftly to 36 million. Close to half of the world‘s urban dwellers reside in relatively small settlements of less than 500,000 inhabitants, while only around 1/8 live in the 28 mega-cities with more than 10 million inhabitants.
