“Mobilizing knowledge” suggests that there is need to dynamize the context in which knowledge about risks is developed, shared, and maintained. It conveys the implicit assumption that knowledge is perhaps currently fragmented and stuck in different compartments and bodies, be they institutions, agencies, universities, research centres, communities, individuals.While with this proposal we fully agree with this assumption, we think it is time to abandon the idea of a “knowledge transfer”, as a good that can be moved from the scientific arena into policy making or into administrative practices. The questions that we wish to ask are who should know what, who actually knows, and if knowledge produced in various ways and fields is effective in achieving disaster risk reduction and climate change prevention and adaptation.Three issues seem particularly relevant to explore:- Fragmentation and separations of arenas (i.e. Scientists, Public and private agencies or organizations in the field of prevention)- Changes that have occurred in risk knowledge management strategies overtime- Knowledge management about risk in times of crisis.The main objective of this proposal is to frame a knowledge management system for disaster risk reduction and climate change adaptation that may be considered as a comprehensive reference for establishing, reinforcing, or revising current prevention, mitigation and adaptation strategies. Such knowledge system will embody what has been achieved in different arenas and by different social groups in the field of prevention, preparedness and adaptation.In order to do so, a circular process between scientific and technical analysis and dissemination will be developed, so as to make use of a wider expertise and reach a larger audience. We want to use some of the dissemination activities as small tests of what deem should be done “at large” for creating an effective development, sharing, and maintenance of knowledge.
