Rapid industrialization in a developing country poses a serious threat to the environment and increases the risk of disasters and natural calamities. This work aims to address the issue of disaster management from the legal perspective. An attempt is made through case studies of Bhopal Gas Disaster and Fukushima Nuclear Disaster to trace the evolution of legal systems in disaster management. The impact of these disasters on existing legal systems of India as well as other countries will be studied to find out the preventive steps taken and to identify the lacunas that need to be addressed to cope up with these alarming situations. The legislations in existence before the Bhopal Tragedy are compared with the legislations proposed or enacted after the incident. The adherence to the concept of strict liability can only be achieved through implementing a global framework as such an incident has trans-national impact. This global framework has its justification in the environment impact of each man-made disaster which is not highlighted and is over shadowed by human sufferings during these disasters.
