Scenario planning














According to the Wikipedia, “scenario planning, also called scenario thinking or scenario analysis, is a strategic planning method that some organizations use to make flexible long-term plans. The original method was that a group of analysts would generate simulation games for policy makers. The games combine known facts with plausible alternative social, technical, economic, environmental, educational, political and aesthetic (STEEEPA) trends which are key driving forces. Scenario planning may involve aspects of Systems thinking, specifically the recognition that many factors may combine in complex ways to create sometime surprising futures.”  (http://en.wikipedia.org/wiki/Scenario_planning)

As a part of the studio’s assignment, I am now working on the scenario planning and have more chances to take a close look at it. Scenario planning seems to be a way to develop a meaningful scope for problem-seeking in architectural design is to develop narratives of alternative futures. Players work with main constraints and driving forces to make stories which are detailed description of situations that might come to be. Thus, instead of developing many designs for one presumed future, as architects quite commonly do, one could have one design that works for many conceivable futures.

Walkability


Walkability "The extent to which the built environment is friendly to the presence of people living, shopping, visiting, enjoying or spending time in an area". 



Walkability is a yardstick of distance or environment to walk. Usually, walkable distance is within 1.3 mile (2 km). But, walkability is measured by not only distance, but also many factors such as the quality of road, gradient of pathway, other pedestrians, safety, environment, level of closeness with buildings, and so on. In contemporary urban planning and design field, walkability is big issue to consider, because of benefits of walkability. Walkability is related with physical and mental health of local people. According to the research by Russel Lopez, walkability in a community brings personal and community benefits such as increasing the number of friends, pride of community, and reducing the number of obesity, crime because of more and more people walk on roads, carbon footprints by automobiles. In this circumstance that more than one third people suffer from obesity in U.S.A, planning and designing walkable city is the most important task for urban planner.  



Urban planners used to design the cities for automobiles and neglect the needs of human being. For example, Brasilia, which is the capital of Brazil, was planed and developed by Lúcio Costa and Oscar Niemeyer. Massive buildings and roads that ignored human scale changed the city bad place to live. The long distance between buildings forced people to use a car, and beautiful street destroyed and abandoned. 
Urban planners should try to build more walkable city to avoid to plan another destroyed city.
