There is no centralised agency to estimate the economic losses from disaster. However, the economic losses due to calamity are adjudged case-to-case basis by the State Government concerned, as they are primarily responsible for management of natural disaster.
National Institute of Disaster Management (NIDM) has informed that based on the best current international practices and customized to local conditions, a Post Disaster Needs Assessment (PDNA) Tools for India has been developed under the National Cyclone Risk Mitigation Project assisted by the World Bank. The objective of these tools is to establish a standardized mechanism based on scientific approach for conducting post disaster needs assessment for recovery and reconstruction and identify the sector-wise losses. These tools are based on the existing damage assessment system in India and an internationally-accepted methodology which has been used worldwide and adopted by the United Nations Development Group (UNDG), the European Union (EU) and the World Bank (WB) on Post-Crisis Assessments and Recovery Planning. This methodology is not a replacement or substitute for the existing approach which States use for the development of the Relief Memorandum. It is the methodology which deals with a separate and additional area of disaster management i.e. recovery and reconstruction following a disaster while building resilience to future events.
