This volume explores the intersection of emerging technologies-particularly artificial intelligence, autonomous weapons systems, and cyber warfare-and their impact on children in armed conflict. Through a multidisciplinary and multi-author approach, the handbook highlights how new technologies are reshaping warfare, complicating the application of international humanitarian and human rights law, and exacerbating risks to the most vulnerable populations: children. It offers legal, ethical, and policy-oriented insights aimed at strengthening child protection frameworks in this rapidly evolving landscape.
