This book is the first attempt to explore the use and application of Information and Communication Technology (ICT) and related smart technologies in cities and for the sole purpose of reaching positive peace. The everyday usage of digital technologies in cities encourages us to study the benefits, co-benefits, disadvantages, and threats of ICT application in cities and urban environments. The continuous growth of digital technologies and their growing demand in everyday urban practices and systems are already known to scholars, practitioners, and policy-makers. However, this book explores whether or not such applications and usage help us reaching positive peace. This approach is novel in the field of urban studies, allowing us to identify and highlight best practices, successes, and failures of ICT application to meet positive peace pillars.  The scope of the book highlights our focus on positive peace and its eight pillars, mainly how they are meant to be achieved in cities and urban areas. With an analytical view on the topic, we aim to reflect on the systematic features of urban systems, using positive peace pillars as the primary targets. We believe ICT application and usage in cities could be more directive and beneficial to reach peace and prosperity to achieve such a goal. Therefore, this book provides a holistic guideline and coverage of ICT use for positive peace pathways and peace-building practices. We hope the findings of the book help researchers and policy-makers to come up with novel and integrated strategies, ensuring that our everyday usage of digital technologies, ICT, and smart tools, are more meaningful and people-oriented.
