Rapid urbanization has emerged as an undeniable global trend. Ever since 2008, more people in the world, live in urban areas than in the countryside. In 2014 alone, 54% of the world’s population resided in urban areas. This puts an extraordinary level of pressure on urban centres which account for only 2.8% of the world’s land area. All these facts point to the distending of urban infrastructure and services beyond their carrying capacity. This is particularly true of Asia, where by 2030, 55% of the continent’s entire population is expected to live in its urban centres. Moreover, over 70% of the region’s GDP is generated from its cities.
