This volume presents a high-level scholarly discussion on whether the concept of solidarity
functions as a structural principle of international law and to what extent it has become a
full-fledged legal principle. Each contributor addresses these questions by examining normative
operations of the principle of solidarity in different branches of international law -
including international disaster law international humanitarian law the law of development
cooperation and international environmental law - as well as the relationship between the
principle of solidarity and other legal principles such as the responsibility to protect and
intergenerational equity.
