Introduction
The Disaster Information Management System (desInventar) is a sustainable arrangement within an institution for the systematic collection, documentation and analysis of data about losses caused by natural and man maid disasters. www.desinventar.lk
Objective
• To analyze the disaster trends and their impacts in a systematic manner
• To reduce the impact of disasters on the communities by planning and implementing appropriate prevention, mitigation and preparedness measures with better understanding of the disaster trends and their impacts
Methodology
• The Disaster Information Management System (DesInventar methodology) includes a software product with two main component,
The DesInventar module• A relational and structural database through which the database is
fed by filling in predefined fields (space and temporal data, types of events and causes, sources)and by both direct and indirect effects(deaths, houses, infrastructure, economic sectors).
The DesConsultar module
• Allows access to the database by queries that may include relations among the diverse variables of effects, types of events, causes, sites, dates, etc. T his module allows at the same time to represent those queries with tables, graphics and thematic maps.

Summary of Incident Occurrence in 2012
Experienced Issues
• Issues Related to Terminology (Data event / Data Card/ Disasters)
• Spatial unit ( Administrative unit Divisional Level)• Not clearly define the duration of event or disaster• Strong Vertical Integration and weak horizontal
integration• Less focus on damage loss assessment• Resolution and information are not enough to do
detail risk assessment
For Sustainability…..
• Mainstreaming Desinventra into different Sectors.
