					MODERN ERA:
 1750 - 1914
   DEMOGRAPHY AND THE
 ENVIRONMENT IN AN AGE OF
     REVOLUTION AND
    INDUSTRIALIZATION
DEMOGRAPHIC TRANSITION
Malthusian Economics
   Predicted human population always outpaced food, supplies
   Only natural disasters, wars, famine keep population low
   Did not figure in technology, inventions, science
Key Characteristics
   Population
    • Increased from 900 million (1800) to 1.6 billion (1900)
    • In Europe, Asia, North America
    • Scientific, medical advances
          – Increase life span, infant survival rate
          – Decrease death rate, death of mother during childbirth
          – New hygiene
   Food supply increases
    •   Lightly, uninhabited areas brought under cultivation
    •   World trade allows for foods to reach areas quicker
    •   Staples in world trade due to refrigeration, canning, ships
    •   Agronomy, animal husbandry increase yields, variety, quality
          – Fruits of the Columbian Exchange
          – Many nations begin to export quantities of wheat, meat
   Population Movements
    • Internal Migration to unsettled lands, international Migrations
    • Urbanization
    • End of Slave Trade necessitated labor based migration
  GRAPHING MALTHUS &
DEMOGRAPHIC TRANSITION
2ND AGRICULTURAL REVOLUTION
 In 1750 the world was largely subsistence agriculture
    Rhythms of regional agricultural societies based on seasons, surroundings
    Small plots, rural villages, no export: exception were Russia, Baltic
 Began in England but also occurred in Western Europe, US, Asia
    Outgrowth of Columbian Exchange
    Outgrowth of the Scientific Revolution
 Enclosure Act
    Larger landowners begin to enclose lands
      •   Began with enclosure of public lands
      •   Done legally to increase yields of large landowners
      •   Then took smaller farms, plots away from poor farmers
      •   Done with support of Parliament
    Results
      •   Moved small, inefficient farms into better productivity
      •   Brought new lands under cultivation
      •   Freed labor for factories and swelled population in cities
 The Revolution
    New Foodstuffs planted; new styles of crop rotations
    Selected breeds of cattle, dairy cattle, sheep
    Technology, science applied to farming
 Agricultural Revolution followed European imperialism
    Europeans brought their crops, animals with them
    Europeans began exploiting cash crops for commercial profit abroad
FROM PEASANTS TO FARMERS
The process, while social, began with technology, science
   Agronomy and animal husbandry replaced herding
    • Selective breeding, splicing, experimentation
    • Crop varieties, fertilizers to enrich soil
   Farming machinery introduced
    • Thrashers, reapers, seed drills, tractors
    • Muscle , animal power replaced by machines
    • Barbed wire was a revolution
   Transport, preservation made export possible
    • Trains, ships with large holds
    • Grain silos, refrigerator ships, canning, food processors
Subsistence Agriculture becomes commercial farming
   Western Europe, US, Canada, Argentina, Brazil, Uruguay
   Australia, New Zealand, parts of India, China, Japan
On the other hand, in some countries
   Peasants went from masters of their own work
   To hands for someone else’s work, or someone else’s work hands
   Russia, Eastern Europe, Africa, parts of Latin America, SE Asia
 COMMERCIAL AGRICULTURE
Commercial agriculture was a revolution 1750 – 1914
   Cash crops: crops grown for profitable export
   Often luxuries or non-necessities with high profit margins
   Two bottlenecks (natural hindrance to profitable production)
     •   Many are labor intensive: solution – slavery, paid agricultural workers
     •   Many require extensive processing, preservation to be useful: solution – technology
   Commercial agriculture is heavily damaging to the environment, soil
First arose during 16th century colonialism
   Caribbean, Brazilian, SE Asian plantations
   Latin American haciendas, rancheros
   First export crops: sugar, hides, wool, spices
Expanded in 18th century
   British North American colonies added tobacco, indigo, rice
   Asia added tea, coffee, opium, cloves
   Americas added cocoa, coffee
Industrial Revolution made additional possible more
   Cotton (seeds); rubber, oil (synthesizing)
   Beef, mutton, grains, dairy (long-term preservation, get to market on time)
   The rest of world, especially Africa enormously effected
   Many areas of world taken from feeding people to exporting for profit
        POPULATION
         GROWTH
The Fruits of Industry
   Industrialization raised material standards of living
  •   Mass production made luxuries into common goods
  •   Workers received pay and able to buy goods, foods
   Better diets and improved sanitation
  •   Reduced death rate of adults and children
  •   Reduced deaths due to childbirth
  •   Increased life span
  •   Decreased infant mortality
  •   Declining birthrate in response to declining mortality
  •   Voluntary birth control through contraception
   Impact on Population
  •   Populations of Europe, America, Asia rose sharply from 1700 to 1900
  •   Increasing urbanization especially of port cities, industrial cities
World Effects
   Change typical of industrialized countries
   Change confined to port cities of non-Western nations
      DOMESTIC MIGRATION
Industrialization
   Drew migrants from countryside to urban centers
   By 1900, In Europe and Anglo-North America
  •   50 percent of population of industrialized nations lived in towns
  •   More than 150 cities with over 100,000 people
   Urban problems
  •   Shoddy houses, fouled air, inadequate water
  •   By late 19th century
      –   Governments passed legislation to clean up cities
      –   Passed building codes, built sewer systems
Internal Migration
   Settlement of Frontiers by population centers
  •   Existing populations expand into plains, prairies
  •   Facilitated by railroads, technology
   Examples
  •   Westward Movement in USA, Canada, Australia
  •   Settlement of Siberia by Russia
  •   Great Trek by Afrikaaners
  •   Chinese settlement of Yangtze, west, Manchuria
  •   Settlement of Brazilian, Argentine interior plains
TRANSCONTINENTAL IMMIGRATION

   •       Asians migrated to Cuba, Peru and the Caribbean sugar fields
       Migration to the cities in Mexico, Argentina, Brazil
MIGRATIONS DUE TO EMPIRE
European migration
      Fifty million Europeans migrated 1800-1914, over half to the US
      Settler colonies in Canada, Argentina, Australia, New Zealand, S. Africa
  •       Most European migrants became cultivators, herders, skilled laborers

  •       Pressure led Boers to migrate to the interior
Indentured labor, contract labor migration
      Most from Asia, Africa, and Pacific islands
  •       2.5 million indentured laborers during 1820-1914
  •       Indentured migrants to work on plantations

Other migrations
      Reflected global influence of imperialism
      Hindu merchants settled heavily in East Africa, S. Africa, Malaya
      Chinese merchants followed contract laborer to Pacific cities
ENVIRONMENTAL DEGREDATION
First era in history when environment seriously threatened by humans
Causes of Environmental Stress
   Industrialization
     •   Pollution increased significantly especially in cities, water
     •   Ability to destroy land for resources increased due to technology
     •   Examples: Industrial areas of Western Europe, Eastern USA
   Technology
     •   Iincreased production on land, from resources
     •   Marginal lands could be settled, exploited
   Demographic Stress
     •   Urbanization, expanding cities destroyed habitats
     •   High Population Densities supported by food
     •   Many acres moved to unproductive status
     •   Examples: Western Europe, Asian/Indian port cities
   Environmental Shift
     •   Farming, ranching changed face of landscape
            –   Ranch animals introduced new fauna, diseases, threats
            –   Farming horticulture introduced new flora
            –   Examples: Americas, Australia, New Zealand, Africa, Hawaii
     •   Switch from subsistence agriculture to commercial agriculture changed face of environment
     •   Forests were the most effected by this shift
   Extinction, Endangerment of Flora, Fauna
     •   Overfishing of areas began, overforesting of areas
     •   Many died out due to competition from domestic flora, fauna
     •   Many were exterminated due to hunting: Passenger Pigeon, Dodo
     •   Examples: United States, Australia, New Zealand
ECOLOGICAL IMPERIALISM
Europeans brought flora, fauna to their colonies
      Preferred European animals, crops; drove out native species
      Ecological imperialism worse in Australia, New Zealand
New crops transformed landscape and society
      Westerners converted colonial landscape to export
  •       Wanted agriculture to be export, profit
  •       Converted farming land to use for export crops
  •       Destroyed centuries old farming systems to plant export crops
  •       Many lands could no longer feed the native population
  •       Plantations used paid, indentured native labor
      Colonial rule
  •       Transformed traditional production of crops and commodities
  •       Indian cotton grown to serve British textile industry
  •       Inexpensive imported textiles undermined Indian production
      Examples
  •       Rain forests of Ceylon converted to tea plantations
  •       Ceylonese women recruited to harvest tea
  •       Rubber plantations transformed Malaya and Sumatra
  •       Americans ran sugar, pineapple plantations in Pacific, Hawaii
  •       Planted coffee, banana trees in Africa, Americas
  •       US interests plant hemp in Yucatan for export
  •       Argentine, Brazilian grains, cattle take over Pampa, Mato Grosso
