In the previous class of VIII, IX and X as students you must have read about various natural and manmade hazards – their preparedness and mitigation measures. In class XI, the Board had introduced frontline curriculum on Disaster Management in Unit 11 of the Geography syllabus. In supplementary textbook on Disaster Management in Geography the Board intends to explain in detail various concepts used in Disaster Management and discussed about the causes, distribution pattern, consequences and mitigation measures for various natural hazards like earthquake, tsunami, flood, cyclone, landslide and drought which are a recurrent phenomena in our country.

I would like to thank Ministry of Home Affairs for their support and guidance in the preparation of the course material and helping the Board in carrying out training programmes for the teachers across the country. I would also like to extend my sincere thanks to the Geography Department, University of Delhi for the support they have extended to come up with the course outline for the Board and also helping in the development of the textbook. My sincere thanks to the UNDP team who have contributed the most and have tirelessly put all their effort in development of the textbook and also carrying out training programmes for the teachers and the school principals across the country without whose support the initiative would have been difficult to continue. I am grateful to the teachers who have played a key role in making the subject so interesting and demanding. Their understanding and interest have made teachers, students and other staff members of the school design the school disaster management plans which have made the schools a better and safer place.
