Disaster management is a multidisciplinary and cross-sectoral field that involves various actors, such as governments, international organizations, non-governmental organizations, civil society, private sector, media, academia, etc. Disaster management also requires the integration of different domains, such as science, technology, engineering, medicine, sociology, psychology, economics, politics, law, ethics, etc.
Disaster management is not a one-time event or activity, but a continuous and dynamic process that evolves over time and adapts to changing contexts and needs. Disaster management encompasses the entire spectrum of actions and measures that aim to prevent or reduce the risk of disasters, prepare for and mitigate the impact of disasters, respond to and provide relief and assistance during and after disasters, and recover from and rebuild after disasters.

What are the main topics covered in Ncert Disaster Management Book For Class 9 21?
In this section, we will give you an overview of the main topics covered in Ncert Disaster Management Book For Class 9 21. We will also provide you with some key points from each unit of the book.
Unit I: Introduction to Disaster Management
This unit introduces the basic concepts and terminology of disaster management. It also explains the types and classification of disasters, and the phases and cycle of disaster management.
Some of the key points from this unit are:
A disaster is an undesirable occurrence resulting from forces that are largely outside human control, strikes quickly with little or no warning, which causes or threatens serious disruption of life and property including death and injury to a large number of people, and requires therefore, mobilisation of efforts in excess of that which are normally provided by statutory emergency services.
A natural hazard is a natural phenomenon that has the potential to cause harm or damage to people or property. A natural disaster is a natural hazard that has actually occurred and caused harm or damage to people or property.
A man-made hazard is a human-induced phenomenon that has the potential to cause harm or damage to people or property. A man-made disaster is a man-made hazard that has actually occurred and caused harm or damage to people or property.
Disasters can be classified into different types based on various criteria such as origin, speed of onset, frequency, duration, intensity, impact area, etc. Some of the common types of disasters are geological disasters (such as earthquakes, volcanic eruptions, landslides), hydro-meteorological disasters (such as floods, droughts, cyclones), biological disasters (such as epidemics, famines), technological disasters (such as industrial accidents, nuclear accidents), environmental disasters (such as pollution, deforestation), social disasters (such as wars, terrorism), etc.
The phases of disaster management are prevention, mitigation, preparedness , response and recovery. Prevention refers to the measures taken to avoid or eliminate the occurrence or recurrence of a disaster. Mitigation refers to the measures taken to reduce or minimize the risk or impact of a disaster. Preparedness refers to the measures taken to enhance the readiness and capacity of people and institutions to cope with a disaster. Response refers to the measures taken to provide immediate relief and assistance to the affected people and communities during and after a disaster. Recovery refers to the measures taken to restore and rebuild the normal functioning of people and communities after a disaster.
The cycle of disaster management is a conceptual model that illustrates the interrelationship and interdependence of the phases of disaster management. The cycle of disaster management consists of four stages: pre-disaster stage, emergency stage, post-disaster stage and development stage. The pre-disaster stage includes prevention and mitigation activities. The emergency stage includes preparedness and response activities. The post-disaster stage includes recovery and rehabilitation activities. The development stage includes development and reconstruction activities.
Unit II: Specific Hazards and Mitigation
This unit deals with some of the specific hazards and disasters that are common in India and the world. It also discusses the causes, consequences and management of these hazards and disasters.
Some of the key points from this unit are:
Floods are overflow of water that submerges land that is usually dry. Floods can be caused by heavy rainfall, snowmelt, storm surge, dam failure, etc. Floods can have positive effects such as replenishing soil fertility, recharging groundwater, supporting biodiversity, etc. Floods can also have negative effects such as loss of lives, damage to property, disruption of services, spread of diseases, etc. Flood management involves structural measures such as dams, embankments, drainage channels, etc., and non-structural measures such as flood forecasting, warning, evacuation, relief, etc.
Droughts are prolonged periods of abnormally low rainfall or moisture that result in water shortage for human or environmental needs. Droughts can be caused by climatic variability, human activities, land degradation, etc. Droughts can have negative effects such as crop failure, food insecurity, malnutrition, health problems, migration, conflicts, etc. Drought management involves structural measures such as irrigation systems, water harvesting structures, groundwater recharge structures, etc., and non-structural measures such as drought monitoring, early warning, contingency planning, relief, etc.
Earthquakes are sudden and violent shaking of the earth's surface caused by the release of energy along the faults or fractures in the earth's crust or upper mantle. Earthquakes can be caused by natural factors such as plate tectonics, volcanic activity, landslides, etc., or by human factors such as mining, blasting, nuclear testing, etc. Earthquakes can have negative effects such as loss of lives, damage to property, collapse of buildings, infrastructure and services, fires, landslides, tsunami, etc. Earthquake management involves structural measures such as seismic design, retrofitting, building codes, etc., and non-structural measures such as seismic zoning, hazard mapping, awareness generation, preparedness drills, emergency response, etc.
Tsunami are series of large waves generated by the displacement of a large volume of water in the ocean or a large lake. Tsunami can be caused by natural factors such as earthquakes, volcanic eruptions, landslides, meteorites, etc., or by human factors such as nuclear explosions, underwater explosions, etc. Tsunami can have negative effects such as loss of lives, damage to property, coastal erosion , salinization, pollution, etc. Tsunami management involves structural measures such as seawalls, breakwaters, mangroves, etc., and non-structural measures such as tsunami warning system, evacuation plan, public education, emergency response, etc.
Cyclones are intense low-pressure systems that are accompanied by strong winds and heavy rainfall. Cyclones can be classified into tropical cyclones and extra-tropical cyclones based on their origin and location. Cyclones can have positive effects such as bringing rainfall, moderating temperature, dispersing pollutants, etc. Cyclones can also have negative effects such as loss of lives, damage to property, flooding, storm surge, landslides, etc. Cyclone management involves structural measures such as cyclone shelters, coastal protection structures, etc., and non-structural measures such as cyclone forecasting, warning, preparedness plan, relief, etc.
Landslides are downward and outward movement of slope-forming materials such as rock, soil, debris, etc. under the influence of gravit
