STEP 1: Preparation of Disaster Impact Assessments

A major component of disaster impact assessments is loss and damage databases that track impacts of hazards over time. This usually covers parameters such as deaths, economic losses, physical damages and losses in the agricultural sector, its sub-sectors and value chain.

Numerous loss and damage databases have been developed over the last several decades which systematically collect and maintain data at global, regional, national and sub-national levels. Hence, it is important to select the most suitable sources, and methodologies, that suits the respective needs. For example, developing guidelines for disaster impact assessments will ensure consistency in reporting in the country and up-to-date monitoring.
