• 6.6 billion people
• 80% in “Pings”
• Over 50% in urban
areas
DENSITY

OVERPOPULATION
Excessive population of an area to the
point of overcrowding, depletion of natural
resources, or environmental deterioration
Thomas Malthus
• British economist in 1798
• Population limited by the
means of food production
• Population will increase
with food production
• Private checks – “moral
restraint, celibacy, chastity
• Destructive checks – war,
poverty, pestilence,
famine
What is the
“carrying capacity”
related to today?
DEMOGRAPHIC TRANSITION
• Based on Western
Europe’s experiences
• Stage 3 - personal
choices – most critical
stage
• Stage 4 – social
customs - women
POPULATION POLICIES
• China’s One-Child Policy
• India’s policy – democracy, education,
family planning
• United States – norms/mores (1750, 1950);
changing demographics

ancestry
Ethnic cleansing is the slaughter or forced
removal of one ethnic group from its home by
another group
Ethnic conflicts – Yugoslavia, Quebec,
Holocaust(?)

•United Kingdom
RISE OF NATION-STATES
1. in response to the rise of nationalist political
philosophies during the 18th century
2. humans want to be close to those of similar
background
3. necessary and logical component of the
transition from feudalism to capitalism
4. logical accompaniment of economic growth
based on expanding technologies
5. arose from the collapse of local communities
and the need for effective communication
within a large unit
GROWTH THEORIES
Wallerstein’s World Systems
•World is divided into three spheres:
core
semi periphery
periphery
GROWTH THEORIES
RATZEL’S SEVEN LAWS OF SPATIAL GROWTH
1. Size will increase as culture develops
2. Growth of a state is subsequent to other
manifestations of the growth of the
people
3. Growth from a process of annexing
smaller members
4. Boundaries are peripheral organs that
take part in all transformations of the
state
GROWTH THEORIES
RATZEL’S SEVEN LAWS OF SPATIAL GROWTH
5. As state grows, it will strive to occupy
some politically valuable locations
6. Initial stimulus for growth is external
7. Tendency to grow continually increases
in intensity
GROWTH THEORIES
What connection is there
between these growth theories
and the concepts of
Environmental Determinism
and
Possiblism?
Colonialism and Imperialism
• Core – higher levels of
education, salaries, more
technology
• Semi-periphery –
transition between the
two
• Periphery – lower
levels of education,
salaries, less technology
INFLUENCE OF ETHNICITY
Ethnic homogeneity of countries
vary, but the extent of a state’s
cultural diversity often
influences its political stability
CHANGES IN POLITICAL
ARRANGEMENTS
Ethnic diversity can be a strong
centrifugal force – leading to civil
disorder, international conflict,
unspeakable human rights abuses
Yugoslavia
CHANGES IN POLITICAL
ARRANGEMENTS
Centripetal Forces
Unifying tendencies,
such as a
widespread
commitment to a
national culture,
shared ideological
objectives, and a
common faith
CHANGES IN POLITICAL
ARRANGEMENTS
Supranationalism
Organization
involving three or
more nation-states
involving formal
political,
economic, and/or
cultural
cooperation to
promote shared
objectives
CHANGES IN POLITICAL
ARRANGEMENTS
Devolution
Process by which
regions within a
state demand
and gain
political strength
and growth
authority at the
expense of
central
government

THIRD AG REVOLUTION
• The complex of seed and
management
improvements adapted
to the needs of intensive
agriculture that have
brought larger harvests
from a given area of
farmland
• 1965-1995, world cereal
production rose 90%,
mostly due to increased
crop yields rather than
expanding cropland
THIRD AG REVOLUTION
• 1965-1983 average yields
• Rice 52%; Wheat 66%;
THIRD AG REVOLUTION
• PEDS haven’t
slowed down –
always pushing
to find new
technologies
• Advancements
in PINGS (Mali)
has helped
delay famine
and extended
life
expectancies
THIRD AG REVOLUTION
• HIGH INPUT – HIGH YIELD CROPS
• New variations of seeds/plants
• Irrigation
• Mechanization
• Fertilization
• Use of pesticides
• More food
THIRD AG REVOLUTION
• Irrigation has destroyed large tracts of
land
• Ground water depletion
• Conflict between agricultural societies
and urban sprawl
CHARACTERISTICS OF THE
THIRD AG REVOLUTION
• Blending of primary, secondary,
tertiary, and quaternary sectors
CHARACTERISTICS OF THE
THIRD AG REVOLUTION
• Increased
mechanization
•Development

biotechnology
HOPES & FEARS ABOUT THE
FUTURE
• Will we be able to produce enough food for
the world’s people? At what cost –
economic and environmental?
INDUSTRIALIZATION AND
ECONOMIC DEVELOPMENT
“HE WHO HAS THE GOLD, MAKES THE RULE!”
GROWTH AND DIFFUSION
Industrial Revolution – w,w,w,w,h
GROWTH AND DIFFUSION
LOCATIONAL ADVANTAGES
• Location theory
helps explain the
spatial positioning of
industries and their
successes or failures
• Transportation,
labor, energy,
infrastructure costs
are all a part in the
location of heavy
industries
LOCATIONAL ADVANTAGES
• Weber’s least-cost
theory
• Growth or decline of
industries are
influenced by
political and
environmental
fluctuations
GROWTH AND DIFFUSION
• Global industrial pattern dominated by the first countries
that industrialized
• Evolution of 3 economic cores and peripheries
GROWTH AND DIFFUSION
• North American
manufacturing
complex is the
largest in the
world today
• Asian Pacific
Rim is the fastest
growing
industrial region
in the world today
LEVELS OF DEVELOPMENT
• Enormous gaps
between rich and
poor, both globally
and regionally
• Underlying
economic disparities
is a core-periphery
relationship among
different regions of
the world
LEVELS OF DEVELOPMENT
• 21st century opened
with some countries
stuck in the primary
sector whereas some
were pushing the
quaternary sector
• Rapid development is
usually associated with
democracy, but some
are growing under
authoritarian regimes
as well
CONTEMPORARY PATTERNS
• Spatial organization of world economy
ECONOMIC RESTRUCTURING
• Declining cost of
transportation and
communication
led to enormous
changes in
tertiary sector in
20th century
• Technology is
accelerating the
pace of life
ECONOMIC RESTRUCTURING
• Deindustrialization
in core has led to
growth of labor
intensive
manufacturing in the
periphery
• International labor
has increased
globalization leading
to both positive and
negative impacts

have their impact as well
URBANIZATION
“Cities have always been
the fireplaces of
civilization, whence light
and heat radiated out into
the dark, cold world.”
- Theodore Parker
STATISTICS OF URBANIZATION
Total Population:
World: 6,666,825,298
USA: 304,052,606
Urban Population:
World: 340,094, 520 or 51%
USA: 243,545,650 or 80.1%

Ga.
CHARACTERISTICS OF URBANIZATION
SITE – the physical
characteristics of a
specific area
Originally located for
commerce and
defense

islands for earliest
cities (Venice,
Paris)
hills useful
because of
defense and
drainage (Rome)
CHARACTERISTICS OF URBANIZATION
Access to fresh
water
domestic
consumption
level of
industrialization,
standard of
living, and
population
growth
CHARACTERISTICS OF URBANIZATION

 Trade and Commerce
 Manufacturing
 Public Administration
 Personal Services
IMPACT OF THE INDUSTRIAL REVOLUTION ON
URBANIZATION
 Urbanization has nearly doubled every 50 years
since 1800
 Mechanization has brought an increased flow of
migrant labor
England was the first place in world history to have more
urban dwellers than rural dwellers (1850)
In 1800, Paris was only European city on mainland to
exceed 500,000; by end of century Paris, Berlin, Vienna,
St. Petersburg, and Moscow all over 1 million!

URBANIZATION
RANK-SIZE RULE AND MEGALOPOLIS
PRIMATE CITY STATUS
A country’s leading city is always is proportionately
large and exceptionally expressive of national
capacity and feeling. The primate city is commonly
at least twice as large as the next largest city and
more than twice as significant.
- Mark Jefferson
PRIMATE CITY STATUS
Not all countries have a
primate city
•India – New Delhi, Mumbai,
Kolkata, Bangalore
•China & Brazil – Beijing,
Shanghai, Sao Paulo, Rio
de Janeiro
RANK-SIZE RULE
• The second and subsequent smaller cities
should represent a proportion of the largest
city. The second city would be ½ the size
of the largest city; the third largest city
would be 1/3 of the size, etc.
- George Zipf
RANK-SIZE RULE
• Paris (2.2 million) v.
Marseilles (800,000)
•London (6.9 million) v.
Birmingham (1 million)
•Mexico City (9.8 million)
v. Guadalajara (1.7 million)
MEGALOPOLIS
• Jean Gottman (1950s)
• 300 mile stretch of BosWash
• Greek for “very large city”
• Inter-linked relationships between a variety
of culturally and political urban areas
MEGALOPOLIS
• Initially colonial settlements from the 1400’s and
grew into villages, then cities, and now urban
areas
•As time progressed, the need for tight
communication between Boston and
Washington increased dramatically
•Currently contains 17% of the country’s total
population in only 1.5% of the total area of the
country
MEGALOPOLIS
• Economic activity, transportation, commuting, and
communications linkages are most important
•Government center, banking center, media
center, academic center, immigration center,
clothing manufacturing, cultural center
•40% of all commercial international airpassenger departures have Megalopolitan origins
•30% of American export trade passes through the
ports of Megalopolis
