Climatic Change, Management of Water Rain and Flood Risk in the Metropolitan Area of San Luis Potosí, México

This paper presents two approaches to interpreting urban system dynamics: (i) the complex systems approach and (ii) the resilient city's approach. It begins with the consideration of cities as a complex and dynamic social system - far from equilibrium and open to their environment - that is composed of elements and actors, that is, endogenous resources, both natural as artificial - elaborated by human societies - that put in value the territorial resources. These are related and are part of other territorial systems of higher order (municipal, state, regional), which, in turn, are within a national system connected to the global scale.
