| Popis: | Resilient historical cities are the product of evolution and they have been shaped by incremental adaptation to fluctuations and by shocks of various magnitudes. Adaptive complex cities operate as systems and they obey certain universal laws: the distribution of elements reflects organic growth processes, such as the ones described by allometric growth and inverse power laws in biology. Their elements and connections organization does not obey Gaussian laws (concentration around averages). They are not aggregates of inert elements but integrated highly differentiated self-organized wholes. They exhibit a hierarchical configurational order characteristic of complex adaptive systems, with nested subsystems ordered in a hierarchy of scales united by mathematical regularities. Planners need to be aware of these laws of adaptive complexity and plan with rather than counter to these emergent properties in order to enhance resilience. Understanding the universality of complex systems order, which characterizes living systems, and which modernist city planning has violated, would allow planning more resilient cities. |
