Global changes involve processes derived from both the dynamics of nature (climate change, for example) as a result of contemporary society (globalization). Even if treated, in most cases as isolated processes, they have high overlap between them, a fact that elevates global changes to a condition of high complexity. Urban social and environmental risks (natural, technological and social) seems to have intensified itself with the advance of modernity, although a detailed examination of its local manifestations lead to the lifting of questions when taken from the perspective of people's vulnerability. Articulate the time-spatial scales of global change and analyze the overlapping of / in urbanization in this process is an unprecedented challenge. The intensification of risk today arises from changes in the nature, society, or the combination of both? RMC - Metropolitan Region of Curitiba is used in this text to illustrate the relevant interrelation between natural and social processes in the genesis of urban social and environmental risks and vulnerabilities. The relationship between population dynamics and the occupation of "fragile" areas - by intensifying social and environmental local risks, respond to global changes in the city? The present study highlights the interaction between extreme hydrometeorological events and urban floods from the analysis between the formation of risk situations and associated social vulnerabilities in the perspective of hybrid risks.
