Spatial Divisions as Forces of Conflict and
Cooperation

• Spatial divisions are regions of the Earths

  cooperation.

17
Examples of Spatial Divisions

• Neighborhoods

18

• School districts

19

• Cities and Counties

20

• Election Districts

21

• Regional Districts

22

• States

23
Reasons for Spatial Divisions

• Why are spatial divisions necessary at the local
  and regional levels?
• 1) Desire for government to be closer to home
• 2) need to solve local problems and
• 3) need to administer resources more efficiently

24

• 4) Citizens and/or politicians may try to gain
  political advantage

  manipulate an electoral area, usually by altering
  the boundaries. This is known as gerrymandering.
  This is done to gain an unfair political
  advantage in an election.

27
Reasons for Cooperation

• 1) Natural disasters
• 2) Economic advantages (attracts new businesses)
• 3) Cultural similaritiesethnic backgrounds
• 4) Addressing regional issues like waste
  management, magnet schools and transportation.

28
Urban Development

• Urbanization, or the growing of cities, was
  triggered by industrialization.
• Patterns of urban development occur according to
  site and situation.

29
Site and situation

• Site and situation are important geographic
  concepts when studying the growth of cities.
• Site is the actual location of a city.

30

• Situation is another name for relative
  locationthe location of a city with respect to
  other geographic features, regions, resources,
  and transport routes.

31
Site

• Harbor Sites NY City, Alexandria, Egypt
  Istanbul Turkey
• Island sites Paris, Hong Kong, Singapore
• Fall line sites Richmond, VA
• Confluence sites Khartoum, Sudan Pittsburg, PA

32

• Hilltop sites Rome, Athens, Jerusalem
• Oasis Sites Damascus, Syria
• Sites where rivers narrow London, Quebec City

33
Situation

• IstanbulCommand of straits and land bridge to
  Europe
• Mecca, Saudi Arabia Varanasi (Benares),
  IndiaFocal point of pilgrimage

  routes

34

  the Great Lakes and Erie canal region to
  worldwide trade and finances

38
What influence does urban areas have on their

40

• They are the headquarters and regional outposts

41
What problems are associated with growth of urban
areas?

• Transportation problems, especially since the

  services (water, sewage, electricity) is a
  problem.

42

• Air, water, and noise pollution
• Sprawl (spreading) of urban areas takes
  agricultural land out of production.
• Rapid migration results in shantytowns on the
  edge of Latin American, Asian, and African cities.

43

• In developing countries, major cities are more
  connected to the outside world than to less
  developed regions in their own countries
