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.
