Early warning systems in the context of disaster risk management

People-centred early warning systems empower communities to prepare for and confront the power of natural hazards. However, the efficiency of such systems is to be measured in terms of lives saved and reduction in losses, which is directly related to the execution of an anticipated response by the people and institutions once a warning is issued.This paper addresses traditional views on early warning systems, and what it takes to transform them into efficient, people-centred systems.
