4
Steam Engine, by James Watt
  • Heralded the Industrial Revolution
  • Pumped mine water
  • Drove machinery
  • Drove railroad engines
  • (Before the steam engine, machinery driven
    manually, by wind, or by water.)

5
Steam Application Locomotive, Railroad
  • Faster, more efficient land transportation, with
    larger loads
  • Steam engine wheels rails
  • U.K. ? Germany France, U.S., etc.
  • Engines considerably sped up local development.

7
Land Cost Example Tokyo Bay
  • Purple is built-up.
  • Green is vegetation
  • High land rents
  • Land built in the bay

10
Skilled labor ? higher productivity, profits
  • Key to manufacturing
  • Literacy
  • Technical skills
  • Strong in EU, US, Russia, China, etc.
  • Weak in Africa, parts of Asia and S. America

14
Situation Bulk GainingLocations near the
customer
  • Reduces distribution costs by adding bulk near
    the consumer.
  • Example, Coke Just add water and carbonation

16
Transportation
  • Transportation part of services sector (Tertiary
    sector, next chapter.)
  • Picking sites with good transportation at the
    location is a site decision.
  • Location central to customers, and near
    transportation modes, are situation decisions.

Market Decline and Stagnation
  • Market Decline can destroy companies , while
    stagnation stalls growth.

    AAAAAAAAKic/ICj7os7vJFU/s1600/Sur2BGoods.JPG

18
Stagnation Agricultural Sector and Trade
  • Demand is flat, sometimes declining!
  • No market growth ? little incentive to enter
    market.
  • (Example grains, from agriculture, same principle
    works here.

20
Increasing Product Supply
  • Plastic Stuff
  • When you get your plastic stuff, see where it
    comes from.
  • Japan
  • Korea
  • China
  • India
  • Shoes
  • When you shop for shoes, look at the tags.
  • Was Indonesia (but we boycotted sweat shops, so)
  • Now made in China

21
Resource Demand Oil
  • Increased demand, but old supplies dwindle
  • More demand, less supply ? higher prices
  • http//www.kkrva.se/images/energi/priddle2.jpg

22
US Petroleum Supply, Energy Use
  • Total demand increases
  • Local production falls
  • Foreign oil purchases, dependency
  • Foreign oil supply and foreign policy are
    critical.

24
MDC perspectives
  • Trading Blocks Example of cooperation
  • Politics chapter
  • Competitive trade advantages (NAFTA, OPEC, )
  • Internal disparities within countries and unions
  • areas of growth and decline
  • (Rust Belt, RD regions such as Silicon Valley)
  • Older, shrinking established populations,
    immigration
  • Population and Migration,
  • (Western E.U. and Japan, Scandinavia, Russia)
  • Transnational Corporations
  • Globalization of production
  • Outsourcing

25
LDC perspectives
  • More Disadvantages
  • distance to (external) markets,
  • inadequate infrastructure (transportation,
    communications, goods, services, tools, machines)
  • entrenched competition,
  • inconsistent governance and laws,
  • government instability,
  • low literacy
  • More Advantages
  • low labor costs,
  • local raw materials (if any)
  • fewer legal restrictions, (e.g. easier to
    pollute)
  • Large labor pools
  • Few or no benefits (health, retirement, vacation,
    etc.)

26
Services
  • Service
  • Any activity that fulfills a human want or need
    and returns money to those who provide it.
  • (Not Manufacturing)
  • Not people making stuff.

27
Service Types
  • Consumer Services
  • Services for people who enjoy them
  • Retail Services sales to individual consumers
  • Personal Services services for the well being
    and personal improvement of individual consumers.
  • Producer Services
  • Services for people who use services for their
    work.
  • banks, insurance, real estate, financial, law,
    engineering, wholesale
  • Transportation and Information Services,
  • Railroads, trucking, phone, airlines, UPS, cable
  • Public Services
  • Provide security and protection for citizens and
    businesses
  • Provide benefits to society as a whole.
  • (Includes teaching)

28
Situation patterns
  • Dispersed Settlements
  • more self-sufficient,
  • lower demand for goods/services
  • Example Mid-Atlantic US ? Midwest
  • Clustered Settlements
  • more interdependent
  • produce better goods by specializing
  • Examples New England, Europe

29
Site Patterns
  • Circular (defensible),
  • Linear (along rivers, roads),
  • Grid (Chang-An, Nara, Kyoto),
  • Long-lot (France, Canada)

30
Central Place Theory
  • (important!)
  • (What do I do when things are important?)
  • Why is it important?
  • Helps explain the distribution of services, and
    why a regular pattern develops.
  • Helps explain migration patterns.
  • Half of the explanation for cities, the next
    chapter.

31
Threshold and Range
  • Threshold minimum population required to
    survive.
  • Range maximum distance people travel for a
    service.
  • http//teacherweb.ftl.pinecrest.edu/snyderd/APHG/U
    nit206/urbannotes_files/image002.jpg

32
Increasing Competition
  • A Less competition circles
  • B More competition overlapping service ranges
  • C Select the closest store ? lines service
    boundaries
  • This produces hexagons.
  • http//www.csiss.org/learning_resources/content/g5
    /materials/G5_Image_Library/de_Blij_figures/IMAGE_
    56.JPG

33
Hexagon Basic shape
  • Highly competitive market
  • all areas are served.
  • Equal services
  • Go to the closest service.
  • Boundaries form the lines of a hexagon.

    501_W1999/501w/cptk7.jpg

35
Central Place Theory Pattern
  • Stores requiring a larger market threshold must
    serve more than one settlement to survive. These
    stores serve a market area encompassing
    neighboring settlements within their range.
  • If the range encompasses one neighboring
    settlement, it encompasses all six.

36
Central Place Theory Pattern
  • This results in hexagons containing 7
    settlements. The central settlements contain
    these (larger market threshold and range) stores
    serving more communities are larger, and are also
    known as more central places. (This gives the
    name to the theory.)
  • Stores with still larger thresholds and ranges
    encompass clusters of these larger communities,
    and are located at cluster centers.

37
Applied Central Place Theory
  • CPT pattern affects migration
  • Jobs,
  • services,
  • convenience
  • Concentration and mixture of cultures,
    development of subcultures
  • Faster dispersion of
  • new ideas, activities, things,
  • cultural change

38
Rank Size
  • Small Towns serve local region, with small range
    stores that contain the population threshold.
  • Castroville often, small store, gas, motel?
  • Medium Towns Sell to small towns within a larger
    local region or service area.
  • King City supermarkets, auto sales, mall CBD
  • Small Cities Serve medium towns within an even
    larger region.
  • Salinas Wal-mart/K-Mart/Cosco, Community College
  • Larger Cities Market to small cities within an
    increasing, larger service area
  • San Jose University, convention center,
    international airport, wide range of services

39
Largest City Comparisons
  • Rank Size Rule (pattern) The nth city (or city
    rank) has approximately 1/n the population of
    the largest city.
  • When the rank size rule does not work for the
    second city, the first city is extremely
    dominant.
  • Primate City Rule (pattern) The largest city in
    a region has more than twice the population of
    the second largest city.
  • You have one OR the other, but not both!

40
Cities History
  • Ancient cities ex Ur, Chang-an, Athens, Rome
    (wall, temples, market, housing, road networks)
  • City states independent self-governing
    communities that included a nearby countryside
  • Medieval cities ex Paris, London (often
    charters of rights, more personal freedom/less
    serfdom)
  • Modern World Cities ex NYC/Tokyo/London (global
    reach/service area, e.g. finance, influence)

41
Central Place Theory Review
  • A threshold population is needed for success
  • This population must be in range for them to buy.
  • With overlapping ranges, people pick closest
    store.
  • (This defines the service area in the simplest
    case.)
  • Hexagons result from closest packing.
  • Then, services need a threshold (population)
    within the service area.
  • A beehive pattern is optimal for consumer access.
  • We find a nested pattern of larger and smaller
    communities, larger communities also have stores
    with larger range, serving smaller communities.

Resources
  • Energy
  • Petroleum
  • Natural Gas
  • Coal
  • Nuclear
  • Minerals
  • Ferrous Iron, et. al.
  • Non-Ferrous Many more.
  • Crucial to the world as we know it today.

46
Pollution
  • Pollution occurs when more waste products are
    generated than a resource (local system) can
    accommodate.
  • Natural
  • Volcanoes, Floods, etc.
  • Human
  • Manufacturing
  • Transportation
  • Consumption
  • Discarded products
  • Waste Products

  • Leavings of the mine
  • Unwanted by-product
  • Tailings also produce
  • Dust

52
Population and Consumption What happens if the
present population increases consumption to the
present first world consumption rate?
  • Use present consumption information
  • Compare the industrial world and the rest of the
    world.
  • Set the world to industrialized world consumption
  • Compare present and fully industrialized
    consumption.

53
1) Find a relative consumption factor
  • MDCs
  • 20 of population uses 80 of resources.
  • 0.2 R1 0.8
  • R1 0.8 / 0.2 4
  • (4 AVERAGE!)
  • LDCs
  • 80 of population uses 20 of resources.
  • 0.8 R2 0.2
  • R2 0.2 / 0.8 0.25
  • (1/4 OF AVERAGE!)

54
2) Compare the MDCs and LDCs
  • Try a ratio
  • R1 / R2 4 / 0.25
  • R1 / R2 16
  • If still true, the First World (MDCs)
  • uses 16 times the amount of resources
  • per capita as the rest of the world.
  • (Amazing!)

55
3) Set the world to MDC consumption
  • Old total consumption
  • (MDCs) (Everyone Else) 1
  • (20 4) (80 .25) 1
  • Fully industrialized total consumption
  • 100 4 4
  • 4 present average (Problem!)

56
Q1 Is this supportable? Realistic?
  • We would run out of oil approx. 4 times as fast.
  • We would have 4 the demand for raw materials.
  • We would have 4 the demand for steel and other
    industrial products.
  • The world would in theory eat a similar calorie
    and meat diet.
  • The world also would adopt our approach
    wholesale.
  • (All are doubtful.)

lecture/pop_images/pop_growth.jpg
  • Article World Population Change Boom or Bust?
  • http//www.uwsp.edu/business/economicswisconsin/e_
    lecture/pop_sum.htm

58
When do we run out? What do we do?
  • Assumptions are used in each model
  • Proven Reserves,
  • Potential Reserves,
  • Reasonable production costs,
  • Note This estimate assumes no coal, nuclear by
    2050, but both are now major contributions.
  • Is this the best mix?
  • What is best? Why?
  • Who picks? How?

What are Recoverable, Unconventional?
  • Unconventional
  • Tar Sands
  • Oil Shale
  • Recoverable
  • Re-tapping old fields (See fracking, and
    associate risks.)
  • Many extraction efforts need new technologies
  • Deeper wells
  • Deep-sea drilling
  • Specialized extraction techniques
  • Many to be determined, developed, or tested,
    risks evaluated.
  • If the oil is not recoverable, we run out.
  • If the oil is recoverable, we pay more and we
    pollute more.

Local Temperature Heat Island Effect
  • This localized effect is different from global
    warming. It is caused by energy use (air
    conditioning, cars, industries, etc.)
  • Source URL http//adaptation.nrcan.gc.ca/perspect
    ive/images/health_fig2_e.jpg

71
Regional Effect
  • Acid Rain
  • Reduces agricultural output
  • Harms species
  • Impacts ecosystems
  • Ex Black Forest, Europe
  • Ex Eastern US

73
  • http//atlas.nrcan.gc.ca/site/english/maps/climate

74
Enhanced Greenhouse Effect
  • The greenhouse effect is natural. Gases absorb
    and re-radiate a lot of energy.
  • Gases CO2, CH4, H2O, NOx, etc.
  • The enhanced greenhouse effect is the additional
    human contribution to those greenhouse gases.
  • The enhanced greenhouse effect is caused in large
    part by fossil fuel use, including manufacturing,
    transportation, and shipping.
  • There are other contributions
  • Cow flatulence,
  • Rice patties

75
Why add the word enhanced?
  • You are more correct.
  • You sound more intelligent.
  • You indicate more of the big picture. (!!!)
  • The greenhouse effect exists without us.
  • Humans enhance it (by burning fossil fuels, etc.)
  • Without the greenhouse effect, the world would be
    a cold place to live.
  • With the enhanced greenhouse effect, the world
    will be a hotter place to live than it has been.

Present Effects Predictable
  • We can model aspects of global warming..
  • Models are incomplete, (always will be), but
    sufficient for prediction.

80
Sea Level Rise

Seas response lags as the oceans absorb
temperature and slowly expand. Land glacial melt
combines with this. http//membrane.com/sidd/tope
xjason2004.jpg
81
Effects are notable. Rate of future change is
uncertain.
  • Glacial retreat (mountain and continental)
  • Sea level rise
  • Land loss, population displacement
  • More extreme events
  • Stronger storms
  • Hotter summers
  • More heat wave related deaths are expected.
  • More droughts
  • Poorer crop production is likely.
  • Stronger winter cold weather events (!)
  • Heat engine more heat ? more circulation.

82
Consequences are expected, but when?
  • Sea level rise
  • Southeast US 8 m.
  • Greenland Ice Cap 7 m.
  • Note Miami, New Orleans, US East Coast cities

  • http//www.fao.org/sd/SDimages/EIre0045.GIF

83
Now for the bad news
  • Long-term consequences of this initial change are
    difficult to calculate.
  • There are positive and negative feedbacks that
    complicate the long-term results, including
  • Economics
  • Population Growth
  • Energy Efficiency
  • Energy Sources,
  • New Technologies
  • Technology adoption

84
Why is it taking so long?
  • Greenhouse gases take time to be absorbed.
  • Greenhouse gas production is going up, not down.
  • New habits and technologies (translation, you)
    are needed.
  • Any new states and transitions will take time to
    complete. Example oceans.
  • Sea level rise is a function of amount of water
    and its temperature.
  • The oceans heat up slowly over time, matching the
    surface temperature regime over centuries. The
    effect is cumulative, but glacially slow.
