Disaster management

The course focuses on the causes of disasters and how to minimise their impact. The course enables the student to learn different areas of disaster management, which includes management of the situation, response to the needs of the people and the area, evacuation process, distribution of food and medical care for the injured people.
During the course, the student will be introduced to environmental systems, eld operations and organisational management, and as disaster management.
There are good employment opportunities the government as well as in private organizations.
Employment opportunities are offered in the disaster management departments of government agencies such as: Fire departments, drought management departments, law enforcement authorities, relief agencies, etc. and insurance companies, industries in the high-risk fields like chemicals, mining, and petroleum which have their own disaster management cells.

Your question gives me the impression that you have absolutely no basic knowledge of how Disaster Management works. The National Disaster Management Authority (NDMA) is the main government body responsible for planning and capacity building to be prepared for an emergency disaster situation. The National Disaster Relief Force (NDRF) is the most important organisation that that deploys personnel for search and rescue operation in the event of a disaster. The National Institute of Disaster Management (NIDM) provides the training for disaster management. All three are part of the Ministry of Home Affairs. The Ministry of Science and Technology has a department of scientists in the field of Geology and Earth Sciences who offer advice NDMA, NDRF and NIDM. The Indian Police Service and the Defence Forces have their own training programmes (for selected personnel) in disaster management and offer their services in the event of a disaster. Apart from what I mentioned above, Aniruddha Academy of Disaster Management (AADM) in Mumbai is a not-profit organisation that provides training and volunteers in the event of an emergency. AADM is suited for teenagers, as the first step, who wants to work in Disaster Management. Finally, the Indian Institute of Remote Sensing (IIRS - part of ISRO) based in Dehradun offers Postgraduate and PhD courses in Geoinformatics, Geosciences, Forestry and Ecology, Marine and Atmospheric sciences. Postgraduates and Doctorates from IIRS work are employed by NDMA and ISRO. My point is that, instead of studying M.Sc in Disaster Management in TISS, I would recommend you to study M.Sc in Geoinformatics or Geosciences at IIRS.if you are eligible. That is the best option. If you are not eligible for these courses, then you can study MA Natural Resources and Governance or MA Rural Development at TISS. These courses will prepare you for 'redevelopment after disaster'. Anyways, you look at it, you should be aiming for a central government job in the field you have chosen or an NGO.
