A Walloon spatial simulation model of risks in environment and health

To develop a spatial and quantitative analysis of health problems related to the environment is a challenging exercise combining different factors of risk and many actors. Using geographic information systems (GIS), multi-criteria decision theory and fuzzy logic, our risk simulation model aims to support decision makers to better understand, analyse and manage the health of the population in relation to environmental pollutions. This tool will be used within an exchange platform between the responsible authorities such as data providers and experts in health and environment to set up priorities in managing the complex system of health and environment at the level of the Walloon Region. This paper describes the purpose of this simulation model of risks, its technical development with a first set of simulation data and the proposed way of using this tool by authorities.
