‘Smart Cities’ are much more than digital solutions and cutting-edge technologies. A smart city is citizen-centred - responding to the needs, realities, and aspirations of its citizens; using technology and innovation to improve their lives and livelihoods. The UNDP Smart Urban Handbook explores how any city can be a smart city. Cities on this smart city journey can learn from and leverage a global toolkit of smart urban innovations and applied insights to tackle key city challenges or address citizen priorities. The Handbook is a tool to support policymakers, civil society organizations, and urban innovators in shaping livable, inclusive, and sustainable cities.
