The aim of this book is to further strengthen the knowledge of readers on management of disasters so that they are better prepared to cope with more frequently occurring natural and manmade disasters.

The process that helps us to face disasters effectively is commonly known as disaster preparedness.  When a disaster strikes, it affects us directly and immediately. While as the government, international agencies such as United Nations, Red Cross Society, non government organizations, like Ramakrishna Mission, OXFAM, CARE, resident welfare associations in urban areas and panchayats in rural areas assist us when faced with disasters the community, invariably remains the first responders. Hence, the individuals as a part of community should prepare adequately to prevent, face and respond to disasters effectively. History has  shown that where communities have prepared adequately to confront disasters, losses to life and property have been less and environment could be protected. People living in an area may be prone to more than one type of disaster. For example Kutch District of Gujarat is vulnerable to floods, drought, cyclones and to earthquakes. Such an area is called ‘multiple hazard’ zone.

The United Nations had declared the decade of 90s (1990-1999) as the International Decade for National Disaster Risk Reduction to enable developing countries to build up their capacity to cope up with disasters. The Government of India also set up a High Powered Committee (HPC), in August 1999, to review the preparedness and mitigation of natural and manmade disasters and recommend measures for strengthening the organisational structures and a comprehensive model plan for management of disasters at national, state and district level. The HPC after due deliberatons submitted the report in Feb. 2001. The HPC identified the disasters under the following types (categories) :

Introduction

Drought is temporary reduction in water or moisture availability significantly below the normal or expected amount for a specific period. This condition occurs either due to inadequacy of rainfall or lack of irrigation facilities, unexploitation or deficient availability for meeting the normal crop requirement in the context of the agro-climatic conditions prevailing in any particular area. This has been scientifically computed as Moisture Index (MI). Drought in this context can be defined as adverse MI or adverse water balance which may be attributable not only to a prolonged dry spell due to lack or sufficient rainfall but also due to such other factors as excessive evapo-transpiration losses, high temperature, low soil holding etc.

Introduction

Landslides are simply defined as mass movement of rock, debris or earth down a slope and have come to include broad range of motions whereby falling, sliding and flowing under the influence of gravity dislodges earth material. They often take place in conjunction with earthquakes, floods and volcanoes. At times, prolonged rainfall cause heavy landslides, that block the flow of river for quite sometime.

Introduction

Road traffic in cold snowy regions during winter season faces problems, like icing of road, snow compaction and snow storms that obstruct visibility. In snowy region there is also danger of damage due to snow avalanches. Avalanches often severely damage road service facilities or road structures. Quick response and corrective actions are required to cope with the damages, if any avalanche occurs.

Introduction

Forests face many hazards but most common is forest fire. They pose threat to not only forest wealth but also to entire region of fauna and flora seriously disturbing the bio-diversity, ecology and environment of a region. During summer, forests are littered with dry senescent leaves and twigs which could burst into flames ignited by the slightest spark. Forest cover in India is 675,538 km and constitute 20-25% of geographical area.
