Historical Vulnerability Patterns : repeated periodic occurrence of losses Trends : increasing magnitude of losses Impact : high losses being caused by low magnitude events Will be defined and calculated based on:

Patterns : repeated periodic occurrence of losses

Trends : increasing magnitude of losses

Impact : high losses being caused by low magnitude events

The InDisData Project A database of disasters to understand trends and patterns. A systematic geo-referenced inventory of small, medium and large-scale disasters for past 30 years. To rationalize decision making for disaster preparedness, as well as providing an objective base for vulnerability assessment and priority setting. To support planning & policy decisions for disaster preparedness and mitigation.

A database of disasters to understand trends and patterns.

A systematic geo-referenced inventory of small, medium and large-scale disasters for past 30 years.

To rationalize decision making for disaster preparedness, as well as providing an objective base for vulnerability assessment and priority setting.

To support planning & policy decisions for disaster preparedness and mitigation.

Orissa Pilot Process Data collected for 30 districts and 314 blocks from newspapers over a period of 32 years. Data collected from media is compared with Government records. Institutionalization with Government for sustainability. Interpretation and analysis of the data shows new dimensions of risk & vulnerabilities of the State. Orissa ‘Vulnerability Analysis Report’ is being prepared in association with ‘Center for Development Studies’.

Preliminary Findings Epidemics and cyclones are the greatest causes of deaths Epidemics are highly associated with floods, but also occur as independent incidents. Fire is the greatest cause of household destruction, comparable to Cyclone. Floods affect people more than any other type of disaster.

Epidemics and cyclones are the greatest causes of deaths

Epidemics are highly associated with floods, but also occur as independent incidents.

Fire is the greatest cause of household destruction, comparable to Cyclone.

Floods affect people more than any other type of disaster.

Impact on Life Number of people killed in disasters in Orisa Epidemics (19,963 ) Cyclone (20,449)

Impact on Property Number of Houses Destroyed in Disasters Orissa Fire (436,212) Cyclone (376,285) Floods (135485)

Impact on Livelihood Number of people affected Flood ( 31’395,654) Cyclone(11’633,140) Drought(3’408,999) Rains (3’776,359)

Patterns: floods Total number of Victims and Affected by Floods in Orissa

Pattern: Epidemics People Killed by Epidemics in Orissa

Spatial Distribution of Disasters

Relation Floods-Epidemics Number of reports of floods and people killed by epidemics, 11 years, with apparently non-flood related epidemics.

Spatial Distribution of Floods and Epidemics

Relation Floods-Epidemics Number of reports in floods and people killed by epidemics, 11 years, in 5 less-flood prone districts. Districts of Koraput, Kandhamal, Kalahand, Rayadada and Gajapat

Trend: Epidemics Ascending trend of the effects of epidemics in Orissa.

Trend: Fire effects on Housing

Pattern: Fire Seasonal Seasonal Variation in Fire Pattern

Way forward: Definition of a methodology to generate a numeric index based on trends, patterns and impact Calculation of these indices for Orissa Comparison of these indices against other vulnerability index Fine tuning of the whole process Use of the indices in Risk Assessment
