OAR@ICRISATMapping Spatio-Temporal Cropland Changes Due To Water Stress In Krishna River Basin Using Temporal Satellite DataR V RMurthyauthorNatural hazards namely droughts, floods, cyclones, hailstorms, volcanic eruptions, earth quakes, landslides, forest fire, locust outbreak etc, are common on the earth’s surface. Most of them are of climatic origin. Incidence of these hazards causes loss of human life, failure of crops and destruction of ecosystems. Consequently, the social as well as economic conditions of any region is disoriented. Natural hazards cannot be prevented but the loss can be minimized to some extent by taking appropriate disaster mitigation strategies. These strategies can be achieved by developing early warning systems and developing effective communication systems to take immediate action during the incidence of disasters, improving medical services and training to the people individually; how to react when disaster warning announced in a region, on their own without waiting for the help. Thus, disaster management includes warning, prevention, planning, preparedness, monitoring, and assessment and relief activity.GIS Techniques/Remote Sensing2020College of Engineering(A), Andhra University, Visakhapatnam;Dept. of Geo-EngineeringThesis
