This particular training manual explains the various controllers of disaster risk and elaborates on how they are related to each other. Care has been taken to explain these crucial parameters as lucidly as possible. Starting from the fundamentals, the module builds upon and gradually talks about the different aspects of disaster risk management. In addition to this, national and international arrangements are been discussed like the relevant statutes at the national level, the Sendai Framework for Disaster Risk Reduction (SFDRR), Sustainable Development Goals which include 17 goals, the Paris Agreement under the United Nations Framework on Climate Change etc. The aim of including such national and international agreements is to lay stress on the fact that understanding risk is just the beginning and it needs to be complemented by risk governance, investment in resilience and preparedness which fosters disaster risk reduction and ultimately, disaster resilience. This module will benefit trainees, students, researchers and professionals working in or simply interested to learn about disaster risk reduction and management.
