Urbanization is one of the defining trends of this century and a key driver of development. By 2050, around 70% of the world’s population will be living in cities and towns. Asia and Africa will collectively account for a significant majority of the urban growth rate, a development that reflects the growth of both ‘megacities’ and smaller urban settlements in both regions over the past three decades. Today, cities produce around 80% of the global GDP and this importance is likely to continue. Cities also use 75% of global energy and are responsible for 70% of global carbon emissions. Accompanying the pace and extent of urbanization are a number of positive and negative trends — from increased economic opportunities and improvements in lives and livelihoods, through to the potential for greater urban-rural disparity, lower quality of life, and conflict. One thing is clear, cities across the world play a critical role in driving sustainable development.

    However, cities today face numerous vulnerabilities and threats. Without proper planning, policies, and support, urbanization often leads to unnecessary risks and costs, preventing cities from reaching their full potential. Cases such as urban sprawls and the proliferation of informal settlements are increasing, and the communities who reside in such areas often suffer from the poor provision of public services (or lack of) such as healthcare or waste management systems. As their population grows, cities also become more complex, making long-term planning and city management a challenge. Amongst the numerous challenges that policymakers must tackle include those that are environmental, those pertaining to resource allocation, and even social challenges such as reducing intra-city inequalities.

    Cities are providing a wide range of opportunities and possibilities for its citizens and, in order for them to be fully harnessed, cities should be built for and together with its citizens to fully unlock their potential. This includes taking into account the various needs and aspirations of people, making sure that everyone can have equal and inclusive access to services and create urban spaces and environments to enhance livability.
