Globally, the number of natural disasters, the number of people affected and the impact of disaster are increasing. FAO assists countries in reducing disaster-related risks by providing early warnings of food production emergencies and helping to restore food production systems in disaster-affected areas. The urgency of emergency situations, however, often prevents the collection of sufficient georeferenced information. This publication introduces RADAR, a rapid disaster impact assessment tool for agriculture. Successful implementation of RADAR could improve disaster preparedness, facilitate timely relief operations and integrate risk and hazard awareness into longer-term agricultural development planning.
