In the last two decades, aided by recent technological advances in novel technologies such as the Internet of Things (IoT), Big Data, Blockchain, and Artificial Intelligence (AI), smart cities have become an optimal solution to address the challenges of urbanisation, innovation, economic growth, and resource management. However, while numerous previous studies explored smart city developments in Western or Asian countries, relevant research on smart city initiatives in the Middle East region remains scarce. Attending to this gap in the literature, in this chapter we aim to provide a better understanding of the UAE’s smart city strategies from a sociological perspective. Our specific focus is on the following two initiatives: (1) Dubai’s Happiness Agenda, which prioritises citizens’ needs, using technology and data to improve the quality of life, and measuring residents’ satisfaction, using specific tools such as the Happiness Meter; and (2) Masdar City in Abu Dhabi, which embodies the UAE’s commitment to environmental sustainability, using advanced technologies in renewable energy, energy-efficient buildings, and sustainable transport. The results reveal that the UAE has adopted a comprehensive approach to smart city development, emphasising both human well-being and environmental sustainability. By combining Dubai’s human-centred design with Masdar’s environmental focus, the UAE demonstrates a visionary strategy, balancing the welfare needs of its people with the planet’s long-term well-being.
