Multi-agency Multi-level Organisations and Technology for Emergency Response Besides immediate local, regional and national levels of response, international agencies are charged with coordinating aid in an emergency situation. In large scale disasters multi-national military assistance is often necessary and offered. Non-Governmental Organisations and charities also play a vital role. Such multi-agency multi-level responses are difficult to coordinate and demand flexible organisational frameworks and technological support. Recent effective multi-national scientific networks, sensor grids, warning systems, and novel emergency response organisations offer a backbone for the development of systems which are able to respond adaptively to an emergency. This discussion will begin with some of the technologies and multi-agency organisational frameworks that were used to respond to the effects of the Indian Ocean 2004 Tsunami. Then it will cover technologies that are becoming available to improve the situation and how scientific networks and multi-agency coordination mechanisms are a possible basis for a future more effective response. Commercial assistance services as well as emergency response could be covered by the same basic methods to ensure sustainability and frequent updates. The potential of a progressive response to emergencies and assistance at many levels from personal, through localised, regional to international will be stressed. A longer term vision of global and local sensor networks linked to effective, timely and well coordinated warning and response mechanisms will be outlined and examples of forward looking exemplars indicated. The meeting will seek to identify promising directions for future developments.
