Challenges of Urban Change
100
  • Goal: make enough food to survive,
    selling for profit is secondary

Subsistence agriculture

100

Large city of global importance with many connections to cities globally

World City = Global City

100
  • Density of people & houses changes with increasing distance from CBD

Density gradient

100

cities with more than 10 million people

Mega Cities

100

 little income + no car + no supermarket 🡺 health issues

Food Deserts

200

Goal: grow enough cash crops for profit

Commercial agriculture

200

“Explains spatial distribution of goods & services across the region”

Central Place Theory

200
  • skyscrapers, banks, lawyers, government,… are all in this area

Central Business District

200
  • “suburban settlement growing at fast pace while keeping its suburban feel”

  • Can get bigger population than some cities

Boomburbs

200

“white communities migrate out of cities as minorities get in”

  • - in Rust Belt USA (Detroit, Cleveland, etc.), Kowloon in HK

White Flight

300
  • Residential and commercial areas combined together 🡺 easy access to goods & services, less traffic, better environment, higher prices of realities

Mixed use neighborhoods

300
  • How many people need to be within range to
    keep production of goods / services profitable

Threshold

300

(factories & workers’ homes, noise + air pollution)

Industrial Zone

300
  • “prosperous residential settlement outside suburban area, but still with connections to suburban region / edge cities”

  • Internet & modern technologies 🡺 work from home 🡺 rise of exurbs

Exurbs

300
  • “banks refusing loans to urban areas deemed too risky”
        - often African-Americans & minorities 🡺 vicious circle of poverty
        - white areas got cheaper loans 🡺 easier to make wealth
        - not allowed anymore, but effects still remain

Redlining

400

“abandoned land that has been left polluted by last occupants”

Brownfields

400
  • Maximum distance people are willing to travel
    to get goods / service (or to come to city)

  • Depends on uniqueness of goods & size of city

Range

400

(housing for the rich / middle income people)

Residential Zone

400
  • “cities that form their own, distinct economic district, in outskirts of big cities”

  • Often located near major roads / highways & connected with “beltway”

  • Economic districts tend to specialize (ex: university town/transportation hub)

Goods & services available in edge cities 🡺 no need to go to downtown

Edge Cities

400

“zones abandoned by their previous owners due to
       economic or environmental reasons” (ghost towns in west US)

Zones of Abandonment

500

Crops & animals grown without chemicals and in sustainable way
- multicropping or crop rotation, no wasting water, no pesticides for crops
- animals without growth hormones, in open spaces 🡺 healthier / tastier

Organic Food

500
  • Area with socio-economic ties to central place

  • Market Area / Hinterland

500
  • Setting height limit on buildings to keep original cultural landscape

  • Urban infilling: increasing residential density in suburbs (= no urban sprawl)

Ex: height limits in European cities 🡺 few skyscrapers in historical centers

Government Policies

500

“unrestricted growth of urban areas & suburbs over large area of land”

Urban Sprawl

500
  • “one ethnic group sells their houses at cheaper rate out of
            fear that another ethnic group moves in and decreases the
            value of the property”
        - real agents bought houses from the white in USA and rented /
           sold it to minorities at higher price in 1950s-60s

Blockbusting
