Hazards & stakes

Risk assessment on a vulnerable territory requires acquiring, integrating, and processing information coming from the different stakeholders and sources, which is heterogeneous in nature, time and spatial coverage, resolution and accuracy. WP2 main objective is the definition of an effective strategy for gathering, archiving, processing and modeling these data sets.

WP2 considers 3 main tasks:

  • The collecting of co-produced data on time-and-space varying risks. Stakeholders will be integrated in a participative approach for gathering information on the hazards and stakes, including human testimonies, remote sensing data and ground based measurements. GIS-based flexible protocols will be developed for data management and distribution, considering international standards (#T3, #T5).
  • The processing, assimilation, fusion and modeling of heterogeneous data for extracting valuable information and understanding mechanisms. The first objective is to obtain the best possible hazards and vulnerability site characterization through adequate and quick data processing techniques (assimilation, merging and modeling) considering the associated uncertainties (epistemic and random). The second goal is to define and extract the relevant information (parameters) from the data set in terms of warning signals for risk situations and of usability by the stakeholders (#T6). Finally, a main challenge is to understand the interactions between natural and/or technological hazards (cascade effects) and between hazards and the response of the population, including emerging hazards (#T5).
  • The Definition of risk monitoring systems. A main output of this WP is the definition of reliable and affordable monitoring systems (#T6, #M7, #M9), based on both human and instrumental data, which are well understood and agreed upon by stakeholders (#T9). To this monitoring system will be associated the relevant processing techniques for extracting the relevant information (#T6): detection/location of events or incidents, and definition of risk indicators (input for WP3). A special attention will be paid to the quality and clarity of the information coming out from the monitoring system and provided to the stakeholders, depending on their level of knowledge and perception (#T3).
