Since 2007, more than half the world’s population live in cities or urban centers. Estimates show that by 2030, cities will be home to 60% of the global population, a share that will further increase to about 68.4% by 2050. Between 2010 and 2050, it is estimated that between 2.5 to 3 billion people will be added to the urban population worldwide; with the highest growth projected to be in less developed regions such as East Asia, South Asia, and sub-Saharan Africa.ii From MDGs to SDGs, the global community has in the last twenty years witnessed the emergence of urbanization as a key development trend.
