The Guidelines for Rapid Environmental Impact Assessment in Disaster (REA) are guidelines to identify, define, and prioritize potential environmental impacts in disaster situations. A simple, consensus-based qualitative assessment process, involving narratives and rating tables, is used to identify and rank environmental issues and follow-up actions during a disaster.
The Guidelines are composed of four main parts and six supporting Annexes. The main parts include an Introduction to the REA, modules on Organization and Community Level Assessments, as well as Consolidation and Analysis of assessment results. The Annexes include information sources, forms used in the assessment and information useful in managing the REA process.
