Impact of Floods in Indian Scenario -A Structural Analysis (original) (raw)

2020, 4th Disaster, Risk and Vulnerability Conference

Extreme precipitation events, landslides, and floods are the most common natural disasters that affect human society and economy. The recent changes in climatic conditions coupled with increasing anthropological activities increases the incidence of floods in India. Floods not only cause material damage but also human and animal loss. The damage due to floods has increased in recent past compared to the earlier times due to increase in the frequency of floods, encroachment of flood plains and other anthropogenic activities like mining, deforestation etc. Impact of flood in this study was analyzed using time series data of flood for the entire country from1953 to 2018. The data was divided into 2 parts as 'before and after' by considering the maximum area (m.ha) and population affected (m) in a particular year. Ordinal least square method was used to analyse the rate of change of area affected (m.ha), population affected (m), crop area damage (m.ha), damage to houses, human lives lost and total damage (Rs. Cr.) for before and after period. It was found that population (m), damage to crop area (m.ha), damage to houses and total damage (Rs. Cr.) were highly significant at 1 % level whereas other variables viz., area affected (m.ha), and human lives lost were significant at 5 % level for the before period. The data from the after period indicates that population (m), total damage (Rs. Cr.) were significant at 1 % and area affected (m.ha) was significant at 5 % level where as the other variables under study were not significant. The response of the Government to floods through Disaster management acts/policies has reduced the flood loss in the after period. The area, population affected and total damage need to be minimized by sensitizing the population about flood preparedness and management through collaborative efforts at the community level.
