Historically, risk assessment and the concept of risk itself have been dominated by environmental, engineering, and economic sciences. Consequently, in analyzing risk production in modern cities, a rather technical view emerges on risks and urban dynamics. Though scientifically grounded and practically useful, this view fails to capture the social complexity of the city, its paradoxes and causalities. Elaborating on the hypothesis that the life-supporting mechanisms in modern cities are simultaneously life-endangering mechanisms, the article aims to develop a sociological framework to comprehend the dynamics of systematic risk production in the urban milieu. Methodologically, to illustrate the functioning of such mechanisms, we will use historical references and several empirical analyses related to urban research.
