Summary - Introduction to Principles of Urban Environmental Management

  • 1.1 The urban environment - challenges and potential

  • Are industrial areas part of urban areas?
  • What aspects does an urban area have according to Wirth (1938)?
    - Large population size
    - High population density
    - Social heterogenity
    - Permanence
  • What aspects does an urban area have according to Bugliarello (2006)?
    - Population
    - Administrative jurisdictions
    - Function (i.e. Economic function)
    - Territory
  • What aspects does an urban area have according to Cohen (2006)?
    - Population size
    - Population density
    - Administrative / political boundaries
    - Economic function
  • What is social heterogenity?
    Multiple professions / occupations
  • What is a territory?
    Urban area or land that governing bodies have authority over
  • What is urban agglomeration?
    Population contained within the contours of a continuous territory inhabited at urban levels of residential density
  • What is a metropolitan region?
    Both the continuous territory and surrounding areas with lower settlement density, under direct influence of a city
  • Urban areas are generally:
    - Metropols
    - Cities
    - Towns
    - Conurbations
  • What criteria's does an urban area have
    - Administrative criteria
    - Population size
    - Population density
    - Economic characteristics
    - Functional characteristics
  • What types of spaces do cities consist of?
    - Living space
    - Working space
    - Leisure space
    - People space
    - Mobility space
  • What types of alternate mobility spaces are there in a city?
    - Sewage systems
    - Energy systems
  • Which city systems are we unable to see?
    - Big data
    - Food systems
  • What do settlements require to be made?
    1) Access to resources:
       - Agriculture
       - Trade
    2) Subsoil
    3) Technological innovations
  • What are growth drivers?
    - Natural increase
    - Migration
    - Reclassification of urban areas
  • Is population growth equal to urban growth?
    Yes, because all population growth is in urban areas
  • High income country = high percentage of urbanisation
  • Population growth = energy consumption growth.

    Energy consumption of finite sources skyrockets. High demand for food.
  • What are effects of climate change?
    - Temperature and climate change
    - Extreme weather
    - Changes in composition of oceans
    - Sea level rise
  • Problems that cause climate change
    - Use of way too much resources
    - Heavily reliant on non-renewable resources
    - Pollution, degradation and destruction of earth's systems
  • What is the current state of our urbanized world?
    Linear metabolism: Resource input >> Waste streams
  • What causes the massive throughput of materials?
    - dependent on external supplies
    - global transportation based on fossil fuel
    - Without fossil fuels mega cities would not have occured
  • What do we need to do to re-balance the world
    - We need to re-balance us and the environment
    - Tackle challenges and opportunities of urban areas
  • Why do cities have high potential?
    - Density = solutions and potential
    - Unused potential for supply, recovery and production
    - Unused potential of ambitious people
    - Local technical / socio-technical solutions
  • What is the vision for future cities?
    - Local renewable sources
    - Cascading, recovery and reuse of resource flows
    - Maximize potential
  • What was covered?:
    -  Subsoil and technological innovations influence locations and conditions of urban areas
    - Definitions of an 'urban area' differs
    - Population growth = urban growth
    - We have a demand for resources and produce emissions
    - Urban populations form the problem and the solution
    - Circular urban metabolism
