Community-based evaluation for the development of a sustainable disaster early warning system

Ashutosh Sutra Dhar, PhD, Mehedi Ahmed Ansary, PhD


Early warning plays a major role in catastrophic loss reduction during natural disasters. An early warning system should address the needs of the disasterprone community for the system to be effective and sustainable. This article presents a community-based evaluation of an existing early warning system in a disaster- prone district of Bangladesh. The evaluation is based on several questionnaire surveys carried out within the vulnerable communities in the district. A new satellite- based early warning system was also deployed around the district on a pilot basis.The challenges for the new satellite-based system are discussed based on this pilot study. The study revealed that the community level questionnaire survey could be effective for the design of a sustainable early warning system.
