City as Ecosystem[unfinished]

In Uncategorized on October 6, 2010 by mradw

Cities as ecosystems:

Citys are places where human live, interacting with each other and with other living organisms as well as abiotic elements.

Self-organizing system as sustainable or viable if all the system characteristics (or “orientors” as he calls them) are in a satisfactory state.

Healthy(effective)[meeting energy need | Meeting Matter Needs | Biodiversity and Coevolution]

Zero waste


Resilient and self-renewing


Health effective:

Use of solar energy

Autotrophic or regionally autotrophic system

Cycling of matter

Intergration of functions

Erosion ctrl

Network coevolution

Zero waste:

Cycling of matter



Negative feedback loops, facilitated by proximity and functional matching

Resilience and self-Renewal:


Panarchy (nested adaptive cycles); ecological memory

Positive feedback loops



(Bossel 1998)

Sustainable societies

Ethics based on strong emotional connections

Psychological fulfillment[Equitable, Cooperative Social Arrangements | Varied activities for creativity and stimulation | A sense of meaning and belonging through traditions]

Cooperative coexistence [Self-Regulating Communities of Place | adaptive learning and environmental feedback]

Connective practives that nurture and sustain an ethic of care- for each other and for one’s “life-place”

Visibility of the more-than-human world

Protection of cultural, economic and ecological diversity

Solar-based and ecological architecture

Sustainable design of support systems

Another Model (Ecosystem succession Principles for city form and structure) by Newman (1975)

Energy and material

Land and structures



City concentrate power…however, they are sill shaped and structured by one fundamental driver: personal mobility. Average: 30min travel time (this is interesting)

Walking city: Copenhagen | Bern, Switzerland | Mesopotamia | Persia | Roseland | some Chinese Cities | (old cities, traditional cities)

Transit Cities: mid-1800s rail node

Automobile Cities: since 1950s, rapidly in the new world high ecological footprints and high economic costs. Social Problems
