While a more traditional approach to international law and armed conflict focuses on the use of force and international humanitarian law, this book incorporates other international legal regimes such as human rights law, international private law, international criminal law, environmental law, as well as regional and national legal regimes. In doing so, a broader picture emerges and reveals the current challenges faced by lawyers in regulating armed conflicts. This in turn highlights the complexities, intricacies, and the interrelationship of the different regimes that may be rendered applicable to armed conflicts. Also, in taking a more inclusive approach, this book provides a new perspective on both existing and emerging themes in this field. The topics covered in this book include privatisation of warfare, protection of the environment, use of natural resources to support armed conflicts, involvement of children in armed conflicts, the relationship between peace, security and justice.
