It has long been established that sustainable development and disasters are closely interlinked at the policy and institutional levels. The focus of this article is to identify the legal issues raised by interoperability between disasters and sustainable development. In particular, the chapter charts the parameters of sustainable development law that are relevant to the context of disasters. In doing so, it identifies that international and regional documents had already prefigured the framework of action to the development and disasters intersection through the lens of prevention. Therefore, legal principles and rules of prevention and cooperation to that effect, as developed in sustainable development law, and more concretely in environmental law, have played an important role in the systematization of rules relevant to the disaster context, and ultimately to the formation of the disaster law.
