ANALYZING WORLD EVOLUTION AND ITS EFFECTS ON URBAN DESIGNING

Our society's modalities of communication and hence our cities have been rapidly changed due to emergence of several revolutions most lately the digital one. In fact, recently with emergence of the fluid, responsive, kinetic, data-driven worlds of infoscape and its combination with urban landscape, urban designing faces a radical reshuffling of a number of its principal underpinnings. It seems that once again we as urban designers in order to catch up with the current world's situation need to evolve or in better words to re-ontologize concepts of urban designing for twenty-first century. Therefore; in this paper for better understanding of the main characteristics of current changes we try to identify the effects of new actors on urban structures trough analysis of different evolution phases of our cities. To do so we make a diagram called "Evolutionary Trend" trough which we can trace world's evolution history to help us know where we are and what may happen in coming decades. This "evolutionary trend" can be used as a guideline for urban designers to help them navigate better in future.
