Cities are more vulnerable than rural areas to a host of risks. Natural hazards like earthquakes or social risks like vandalism and crime have a far greater impact there. Moreover, the infrastructure of our cities is increasingly networked, and while smart cities may offer more in terms of security and convenience, data protection often falls by the wayside. Since risks are frequently interconnected, we need to take an integrated approach to managing them. A concept for risk governance elaborated by IASS researchers in the International Journal of Disaster Risk Science reflects just such an approach.
