Volume 25 of the Yearbook of International Humanitarian Law (IHL) sheds light on the interplay between IHL and other adjacent branches of international law. This Volume moves beyond the traditional preoccupation of examining IHL’s relations with international human rights law, the law on the use of force and international criminal law. Authors were invited to discuss, both in general and specific terms, doctrinally and theoretically, interactions between IHL and other neighbouring frameworks. Accordingly, this Volume is dedicated to exploring the interrelationship between IHL and other adjacent frameworks, such as international environmental law, international investment law, the law on defences to state responsibility, and counter-terrorism law.
The Volume contains four articles dedicated to the subject of IHL and neighbouring frameworks. The Volume further features a Focus section on IHL controversies arising from Russia’s aggression against Ukraine, and ends, asusual, with a Year in Review section.

The Yearbook of International Humanitarian Law is a leading annual publication devoted to the study of international humanitarian law. The Yearbook has always strived to be at the forefront of the debate of pressing doctrinal questions of IHL, and will continue to do so in the future. As this Volume demonstrates, it offers a space where IHL-related issues can be explored both from a doctrinal and a theoretical perspective. It provides an international forum for high-quality, peer-reviewed academic articles focusing on this crucial branch of international law.

Distinguished by contemporary relevance, the Yearbook of International Humanitarian Law bridges the gap between theory and practice and serves as a useful reference tool for scholars, practitioners, military personnel, civil servants, diplomats, human rights workers, and students.
