Disaster Resilient Infrastructures in India

India's urban and semi-urban areas are choked with unplanned structures built haphazardly over the years. These areas are extremely vulnerable to various disasters and many cities like Delhi, Mumbai are like ticking time bombs.

Abstract: Disasters have been inflicting heavy damage in terms of deaths, injuries, destruction of our habitat and economic activity. While over the last two decades India has much to share about its successful response in terms of minimising life loss—infrastructure damage however, have remained very high. The economic impact of these extreme events are required to be evaluated, particularly in the light of growing urban and coastal establishments of the country. Citing case studies of vulnerable built up facilities, this article presents disaster resilient infrastructure issues in India.

What is ...

Avulsions are the natural processes by which flow diverts out of an established river channel into a new permanent course on the adjacent floodplain abandoning the former channel.

Biological hazards are organic substances that pose a threat to the health of humans and other living organisms. Biological hazards include pathogenic microorganisms, viruses, toxins (from biological sources), spores, fungi and bio-active substances. Biological hazards can also be considered to include biological vectors or transmitters of disease.

Cloudburst is a sudden, very intense localised rainfall of brief duration. Most cloudbursts are accompanied by thunderstorms. Violent uprushes of air withhold the condensing airdrops from falling leading to dangerous levels of water accumulation in the cloud which is then released all at once upon weakening of the uprush.

Disaster risk reduction is the concept and practice of reducing disaster risks through systematic efforts to analyse and reduce the causal factors of disasters.It aims to reduce damage caused by natural hazards like earthquakes, floods, droughts and cyclones, through prevention.

Earthflow, is a sheet or stream of soil and rock material saturated with water and flowing downslope under the pull of gravity; it represents the intermediate stage between creep and mudflow.

It is a term coined by Essam El-Hinnawi, which describes “people who have been forced to leave their traditional habitat, temporarily or permanently, because of a marked environmental disruption (natural and/or triggered by people) that jeopardises their existence and/or seriously effects the quality of their life”.

A geologic hazard is an extreme natural event that occurs within the crust of the earth and poses a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis (tidal waves) and landslides.

A atmospheric, hydrological or oceanographic phenomenon that may cause loss of life, injury or other health impacts, property damage, loss of livelihoods and services, social and economic disruption, or environmental damage (includes tropical cyclones, thunderstorms, hailstorms, tornados, blizzards, heavy snowfall, avalanches, coastal storm surges, floods including flash floods, drought, heatwaves and cold spells).
