Disaster law encompasses a multifaceted legal framework designed to mitigate, respond to, and recover from disasters. This chapter explores the evolution and principles of disaster law, focusing on its role in managing natural and human-induced disasters. Key components include legal provisions for disaster risk reduction, preparedness, emergency response, and recovery efforts.

An analysis on the potentials and challenges of legislative measures are discussed, and specific section focuses on adaptive governance, which becomes extremely relevant in the current complex global risk landscape. Ultimately, the chapter underscores the crucial role of disaster law in enhancing resilience, protecting lives and livelihoods, and fostering sustainable development in the face of increasingly complex and interconnected risks.
