Spatial Divisions as Forces of
Conflict and Cooperation
Spatial divisions are regions of
the Earth’s surface over which
groups of people establish social,
economic and political control.
Spatial divisions may generate
conflict and/or cooperation.
Examples of Spatial Divisions
►Neighborhoods
►School
districts
►Cities
and Counties
►Election
Districts
►Regional
Districts
►States
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
►How
Reasons for Conflict
do spatial systems
generate conflict?
►1) Citizens may argue over
boundaries;
2) Citizens may have low
tolerance for different cultures;
3) Citizens may fight/compete
over scarce resources and
4) Citizens and/or politicians
may try to gain political
advantage
Political Advantage?
►Yes,
spatial divisions can be
created in order to 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.
Reasons for Cooperation
1) Natural disasters
2) Economic advantages (attracts
new businesses)
3) Cultural similarities—ethnic
backgrounds
4) Addressing regional issues like
waste management, magnet
schools and transportation.
Urban Development
►Urbanization,
or the growing of
cities, was triggered by
industrialization.
►Patterns of urban development
occur according to site and
situation.
Site and situation
►Site
and situation are
important geographic concepts
when studying the growth of
cities.
►Site
city.
is the actual location of a
►Situation
is another name
for relative location—the
location of a city with respect
to other geographic features,
regions, resources, and
transport routes.
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
►Hilltop
sites: Rome, Athens,
Jerusalem
►Oasis Sites: Damascus, Syria
►Sites where rivers narrow:
London, Quebec City
Situation
►Istanbul—Command
of straits
and land bridge to Europe
►Mecca, Saudi Arabia; Varanasi
(Benares), India—Focal point of
pilgrimage
►Samarkand, Uzbekistan; Xi’an,
China; Timbuktu, Mali;
Singapore—Cities that grew up
around trade routes
►Capetown,
S.Africa—Supply
station for ships
►Omaha, Nebraska;
Sacramento, California—Cities
that grew up along the U.S.
Transcontinental railroad
►Novosibirsk,Vladivostok-Cities
that grew up along the TransSiberian Railroad
Functions of towns and cities
►Security
and defense
►Religious centers
►Trade centers (local and long
distance
►Governmental administration
►Manufacturing centers
►Service centers
Examples of a city changing functions
over time
►Rio de Janeiro—was the capital
but now is a tourist attraction
(Brasilia)
►Pittsburgh, Pennsylvania—early
function was for frontier
defense, then shifted to steel
manufacturing, and now is the
home to many diverse services
►New
York City—has changed
from a center of coastal and
transatlantic trade to a center
for the Great Lakes and Erie
canal region to worldwide trade
and finances
►Mining towns– once the
resources were gone, many
towns became “ghost towns”
What influence does urban areas have
on their region and country?
►They are the home to monuments
which help bring pride and develop
nation-building.
►They are transportation and
communication centers.
►They are natural attractions for
immigrants.
►They
are the seed beds for
new ideas and technologies.
►Their diversity helps lead to
creativity in the arts.
►Many are the home to major
Universities which provide
educational opportunities.
►They
are the headquarters and
regional outposts of major
corporations.
►The major media outlets have
their centers there
(newspapers, radio, and
television).
What problems are associated with
growth of urban areas?
►Transportation problems, especially
since the automobile.
►Rich and poor neighborhoods are
usually isolated from one another.
►As overcrowding occurs, providing
essential services (water, sewage,
electricity) is a problem.
►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.
►In
developing countries, major
cities are more connected to
the outside world than to less
developed regions in their own
countries
