Floods 2 : risk management

Abstract

Crowdsourcing and crisis-mapping are concepts supported by the involvement of a large number of persons that enable, in a voluntary way, consolidation of information collected in situ during the course and progress of a phenomenon (such as a flood for example). The term 'volunteerism' is generally used to refer to activities that are non-obligatory (there is no contractual, familial or friendship obligation between the helper and the helped, nor coercion). Data collected is often of a geographical nature, and the tools used for collection (internet, mobile technologies), and publication of this data (websites, map platforms), enable it to be shared instantly and quickly. When floods occur, this input can help to assess the seriousness of a situation, and to guide disaster relief operations for victims
