Natural Disasters

The term 'Disaster' occurs with such tragic frequency in news reports today, that it seems superfluous to define it. 'Official' definitions are suggested by the United nations and  the Disaster Management Act. Simply put, a disaster is a  rapidly occuring event that leads to loss of lives and property.  Loss is the defining characteristic of a disaster. With the exception of industrial and other manmnade accidents, the cataclysmic events that lead to this loss are necessary landforming mechanisms.

Earthquakes, floods and resultant landslides, cyclones, and other such events are the processes through which the  earth relieves pressure that might be building up in the crust, reforms river beds, and relieves buildup of atmospheric pressure. When humans are caught in the midst of these events and suffer damage and loss, the events are termed disasters. 

It is not to be denied that these events can be catastrophic in their impact.  The Bhola cyclone, in 1970, caused the deaths of 5 lakh people in India. Three decades later, the Orissa cyclone in 1999 killed 10,000 people.
1. Types of disastersNatural Disasters Infographic (Source: Alexandra Curtis)
Disasters, events that lead to a considerable loss of  life and property, can occur in several ways. The broadest means of  classfication are as manmade and natural disasters. Manmade disasters include industrial and chemical disasters, stampedes, nuclear emergencies, transportation accidents (road, rail, air  and sea), and mines. These, while important, are not withing the purview of the India Water Portal. The discussion therefore will be confined to natural disasters. Natural disasters of course can be exacerbated by human interference such as in the case of landslides which are intensified by  blasting in mountain areas, and floods which are intensified by inappropriate channelization of  river courses.

2. Dealing with disasters:
Traditional means of managing disasters has been confined to response. This is the  rescue and aid that is given immediately after an event. In some cases, rehabilitation has been done, which is ensuring that the aid that disaster  victims need to begin their lives over again is available. In recent years though, the purview of  disaster management has expanded across the continuum of disasters to include mitigation and reconstruction. These now include:

  • Prevention and mitigation
  • Preparedness and response
  • Recovery, reconstruction and rehabilitation

3. Institutional framework in India
Disaster management in India was earlier predominantly focused towards responding to requests for aid after a disaster. However, the nineties saw  series of catastrophic events which led to the creation of a holistic policy of disaster management. The National Disaster Management Authority (NDMA) was established with the vision of a disaster- resilient India; created by enabling prevention, mitigation, preparedness, and effective response (National Disaster Management Authority, 2009).   They recommend the inclusion of disaster prevention, mitigation and preparedness activities within the scheme of disaster management. The  NDMA also recommends several measures at various levels from the national to the individual. A crucial part of these is the formation of State Disaster Management Authorities which oversee the implementation of  the NDMA policies in their states. An important part of the institutional framework to deal with disasters is the emergence of community-led institutions. These range from pan-regional networks such as HYCOS in  the Hindu Kush Himalayas to the village-based flood alert systems seen in Assam. These are explained in David Molden's talk below:

 

4. Voluntary organisations
Despite the existence of the National Disaster Response Force, the first responders on the scene are often local communities and voluntary organisations. The outpouring of support that one sees in the immediate aftermath of a disaster is a matter of pride for the nation, as citizens rally together to support the stricken communities. Local communities do stellar work in immediate rescue of afflicted people. This is especially crucial during landslides in the mountains when afflicted areas can be rendered inaccessible. Communities  that are farther away from the scene of the disaster also rally around when it comes to the  donation of supplies such as food, clothing and shelter. However this  community-driven and impulsive response is largely confined to the rescue and response stages. The delivery of relief material can also be inefficiently handled due to the inexperience of the people dealing with the situation.

It is here that voluntary organisations come to the forefront. They usually have a network of contacts and are able to mobilise both goods and personnel in an efficient manner. Past disasters such as the Latur Earthquake, Leh Landslides, and Uttarakhand floods have seen all manner of voluntary organisations from NGOs to religious trusts offer support, time, and goods. Voluntary organisations also offer more than just the supply of immediately required food and clothing by assisting with construction of shelters, medical aid, and provision of sanitary facilities.

This is best offered by non-political volunteer networks and organisations that are largely devoted to the provision of disaster relief. These have access to highly skilled personnel, donor agencies, and government networks which enable them to provide superlative assistance as and when needed.

RedR is such a network composed  of engineers. Volunteers with RedR participate in regular training which enable them to offer skilled assistance in times of disaster. Medicins Sans Frontiers is a network of doctors who provide skilled medical care in times of disaster and strife.

2.  Personal responsibility
A large part of the casualties during disasters can be prevented by taking a few steps. After all, the first person present at the scene of an accident is the accident victim. While some events may have some warning, it is always better to be prepared for the unforseeable.

Climate change is one of the most serious threats to the environment, health and economy of our nation as well as the whole world. Posted on 27 Jul, 2011 02:54 PM

Recent scientific studies show that global warming is already causing environmental changes that will have significant global economic and social impacts. As the world's 4th largest emitter of greenhouse gases, India has to juggle the imperative demand for economic development with pressures for greater efficiency in the use of energy.

Climate change is a change in the statistical properties of the climate system when considered over long periods of time, regardless of cause. Climate change reflects a change in the energy balance of the climate system, i.e. changes the relative balance between incoming solar radiation and outgoing infrared radiation from Earth. The threat emanates from accumulated green house gas emissions in the atmosphere, generated through long term and intensive industrial growth and high consumption life styles of developed countries.

Threat of land subsidence in and around Kolkata City and East Kolkata Wetlands – A paper in Journal of Earth System Science
The groundwater of the cities and wetland areas should be developed cautiously based on the groundwater potential to minimize the threat of land subsidence, the report says. Posted on 18 Jul, 2011 07:33 PM

This paper in Journal of Earth System Science attempts to estimate the possible rate of land subsidence of Kolkata City including Salt Lake City and the adjoining East Kolkata Wetlands located at the lower part of the deltaic alluvial plain of South Bengal basin. Land subsidence is an environmental hazard which is caused by overdraft of groundwater or oil extraction and results in gradual settling or sudden sinking of the earth’s surface owing to subsurface movement of the materials of the earth.

Analysing the role of geomorphic features in Kosi flood – An article in Geospatial World
This article in Geospatial World deals with the analysis of the role of geomorphic features in causing and controlling the Kosi flood. The article in conclusion states that canal is a man-made route for free flowing of water towards down slope. During the Kosi flood in 2008, drainage turned into canals and they worked as embankments along both side of drainages, where drainages are flanked by canals. Thus, canal network checks lateral spreading of flood water and saves life and property in adjacent areas. Posted on 12 Jul, 2011 10:45 AM

Kosi is known as the sorrow of Bihar due to its frequent and often disastrous floods. The major geomorphic units of flood-inundated area in Kosi fan (terrain of Kosi river in India) are sand bars in the form of inter-connected drainage networks, an ox-bow lake and its meandering cut-off and imprint.

A record of lake outburst in the Indus valley of Ladakh Himalaya: A paper in Current Science
This study in Current Science on lake outburst in the Indus valley of Ladakh Himalaya deals with the specific case of a paleolake record of outburst discovered at approximately 3245 metres above mean sea level in the Spituk–Leh valley of the Indus river, Ladakh Himalaya. Posted on 23 Jun, 2011 04:45 PM

Interdependence of glacial fluctuations to hydrometeorology and sediment transfer in the connected river basins is well recognized in the Himalayan region. Considering the increased rates of glacial recession during past few decades, possibility of creating new lake basins by glacial melt and damming of rivers followed by lake outbursts and related flash floods is likely to increase.

Recent landslides in Uttarakhand - Nature’s fury or human folly – A paper in Current Science
This paper in Current Science deals with the recent landslides in the hill slopes in the Uttarakhand Himalayas, which are known for their instability due to ongoing tectonic activity. Posted on 21 Jun, 2011 10:22 PM

LandslideHowever, increasing anthropogenic intervention in the recent times appears to be contributing to terrain instability in addition to natural factors, as observed by increasing frequency and magnitude of landslides since 1970.

During August and September 2010, Uttarakhand Himalaya witnessed large-scale slope destabilization, particularly along the roads where widening work was in progress leading to huge damage. The cause of regional-scale landslides has been attributed to exceptionally high rainfall in the region during September. When the average rainfall for the month of August and September from 2000 to 2009 is compared with rainfall data of the same period of 2010, it was found that in September 2010, 336 per cent higher rainfall was received by the area. However, the question that arises is: was it unusual rainfall-induced calamity or a result of human intervention?
