India, due to its geographical locations and geological formations, is a highly disaster prone country. Its long coastline, snowclad high peaks, high mountain ranges, the perennial rivers in the north all combine to add to this problem. India, which has only two per cent the total geographical area, has to support 16 per cent of total world population. Naturally, there is a tremendous pressure on the natural resources, which directly or indirectly lead to the occurrence of disasters, namely floods, droughts, landslides, earthquakes, etc.
Like human population, India has to support large cattle population, which also heavily depends on biomass and graze into forest area. The forest cover with more than 0.4 densities is 12 per cent of the land area, though forest, at present, is 23 per cent. Due to overgrazing the quality of soil is also degrading resulting in soil erosion, silting of rivers, and removal of fertile soil and heavy silting of cultivable land. We see heavy rainfall during the monsoon, sometimes 100 cm rain in 36 hours or getting the whole monsoon rain two to three days like the ones in Maharashtra, Gujarat, and Kolkata. From the region wise analysis, it is clear that northern region of India is faced with problems of avalanches, landslides, floods, drought and earthquakes because this region fall under the seismic zones III to V.
The Eastern region is confronted with the heavy floods in the perennial rivers of Brahmaputra, Ganga, etc. Drought, heat wave, hailstorm, cyclone, heavy wind and earthquake are also common in this region. The Northeastern region faces the natural disaster in the form of flood, landslides, wind outrage, earthquake as most of this part of the country comes under the seismic zones IV and V.
The Western region is widely known for severe drought, wind erosion of land and soil, flood and cyclone. This area is also prone to earthquakes. The Southern region, particularly the coastal region is vulnerable to cyclones, sea erosion, tsunami, landslides. The islands of Andaman & Nicobar and Lakshadweep are confronted with the problems of sea erosion and tsunami. Indian coastal areas faced some of the severest cyclones both in Eastern coast and Western coast. One of the natural disasters, namely the volcanoes is in the barren island in Andaman group of islands which periodically become active.
In recent times, it was active in 2005. Among all the disasters, tsunami is the latest phenomena, which was never seen or heard earlier. Due to having no adequate warning system, it devastated a large portion of coastal region of Tamil Nadu, Kerala and Andhra Pradesh besides Andaman & Nicobar Islands and claimed a large number of innocent lives and destroyed property worth crores of rupees.
India has faced a number of disasters, ranging from flood, earthquakes, cyclones, tsunami, drought, landslides. A few recent disasters faced by India include Uttar Kasha earthquake in UP in 1991, Later earthquake in Maharashtra in 1993, Chama earthquake in Gujarat, super cyclone in Orissa in 1999, Buhl earthquake in Gujarat in 2001, Tsunami in 2004 and Mumbai-Gujarat flood in 2005. Besides, India has a bad experience of technology-related tragedy in the form of gas tragedy in Bhopal in 1984. India also faced the problem of Plague in Gujarat.
The direct or indirect impacts of disasters, either natural or technological, are always damage, destruction and death. They cause loss of life of both men and animals and properties as well. At the occurrence of disaster, everything goes haywire in view of the destruction of lifeline support systems, namely communication, power supply, water supply, drainage, etc. In this situation the health care and hospitals are also put under severe stress. Commercial and economic activities are badly affected. Life almost comes to a standstill.
The impact is almost same, in case of man-made disasters like riots. The worst affected group is the poor sections of society, who are daily wage-earner. They are the most vulnerable and they suffer the loss of their livelihood. The psychological traumas caused by the disasters are sometimes so severe that they span the whole of life of the victim. Besides other rehabilitation works, psychological rehabilitation is of great importance.
In some natural disasters like cyclones, tsunami and earthquake, it is the building structure which becomes the cause of destruction and death. It is due to this fact that in building construction, building codes are not followed property. In developing countries only 30 per cent of built infrastructures are constructed as per the building codes, while semi-permanent and other buildings do not follow the plan. Besides, the low quality of building material, liberal flouting and lack of master plan are some of the major constraints in this regard.
The UNDA with Government of India has jointly prepared an action plan for cities and towns vulnerable to earthquakes. The need in the vulnerable zones is that the existing buildings be technically assessed and evaluated and individual owners and group housing authorities should be informed about the weaknesses in their construction. Presently, in India, it is estimated that around 10 lakhs buildings which are constructed every year, an equal number of them get damaged as a result of disasters. It is required that a monitoring mechanism should be set up in disaster prone areas and it must act in proper coordination with the concerned to ensure fulfillment of building codes.
Disaster is a state subject in India; it is, therefore, the responsibility of the state to provide every kind of support and assistance to the victim. The Central Government has a facilitating role. It, with proper coordination with various ministries, extends all required support and helps to the states, namely defence services, air dropping, rescuing, searching, transport of relief goods, availability of rail and ferry services, health personnel and medical support, etc. In the State, the Relief Commissioner or Disaster Management Secretary is the specific authority responsible for handling and management of the disaster.
At the state level there is a State Level Disaster Management Committee consisting of senior secretaries of various departments and representatives of the NGOs. At national level, there is a Crisis Management Committee headed by the Cabinet Secretary and secretaries from major departments of governments. In 1999 a high powered Committee on Disaster Management was set up by the Government of India to look into the existing disaster management system in the country and to suggest measures to improve it. Besides, a Calamity Relief Fund has been constituted with contribution in ratio 3: 1 between the Centre and the respective State Government. The Eleventh Finance Commission has recommended nearly Rs. 11,000 crore for the period spread over five years, while the Twelfth Finance Commission has also recommended a Rs 23,000 crore assistance for the states.
Rehabilitation is an integral part of disaster management. When disasters occur administrative measures are terribly inadequate and perhaps this is the most difficult period for a victim. The role of administration does not end with end of disasters. In fact its effort and commitment get more complex. It requires proper coordination among various agencies. In this context it is very important to note that disasters are non-routine events that require non-routine response. Government cannot rely on normal procedures to implement appropriate responses- the rescue teams require learning special skills, technologies and attitudes in dealing with disasters.
Disaster Management has assumed great importance in recent times. To handle the situation efficiently, we need to be well-equipped with latest technologies. It cannot avert the situation, but can mitigate its impacts.
