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

Self-regulating

Resilient and self-renewing

Flexible

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

Filtration

Self-regulation:

Negative feedback loops, facilitated by proximity and functional matching

Resilience and self-Renewal:

Diversity

Panarchy (nested adaptive cycles); ecological memory

Positive feedback loops

Flexibility:

Networks

(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

Information

Control/governance

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
