This book delves into the concept of smart cities, namely how modern technologies and excellent governance may transform urban landscapes into more sustainable, efficient, and habitable spaces. Faced with the challenges of increasing urbanization and rising environmental concerns, urban planning must handle issues such as population increase, heightened urban problems, and extensive use of mobile communication technology. These issues underscore the need of smart cities as innovative solutions to contemporary urban challenges. The goal is to offer a thorough introduction to many areas of smart city development, such as smart governance, ethical issues, smart education systems, sustainable energy solutions, and the incorporation of digital technologies into municipal administration. Drawing on detailed case studies and analyzing concrete results as well as obstacles encountered in various smart city projects, this book aims to offer valuable insights and strategies. Intended for decision-makers, researchers, and professionals in the field, this book aims to deepen the understanding of smart city initiatives and improve their implementation, with a view to supporting sustainable urban growth in the face of current demographic, social, and technological challenges.
