Global Population Dynamics

China's Population History and Challenges

  • 1949 Baby Boom: Significant post-war population increase.
  • 1958 Crisis: Following 2 million deaths (due to flooding/famine), the population was encouraged to have babies, leading to a second baby boom.
  • 1979: Implementation of the One-Child Policy.
  • 2015: Policy adjusted to the Two-Child Policy.
  • Current Issues: Unbalanced population ratio (more men), the 4-2-1 problem (high age dependency ratio).

Population Density and Growth Rates

  • Canada: Underpopulated (2.32 people per km²), but experiencing population growth (0.7% annual increase).
  • Tanzania: Overpopulated (153 people per km²).

Russia: Factors Contributing to Underpopulation

  • Low fertility rate and high death rate.
  • Low GDP resulting in a lack of workers.
  • High abortion rates.
  • Low immigration levels.

Liberia: Rapid Population Increase

  • Population increased by 253% between 1950 and 2000.
  • Challenges include civil war aftermath, 85% unemployment, and high infant mortality rates.

Climate and Ecosystem Case Studies

Namib Desert Characteristics

  • Temperature changes significantly from East to West.
  • Geography varies: Tall dunes in the South, rock desert in the North.
  • Characterized by low rainfall.
  • The desert is protected from exploitation, except for some crucial mining operations.

Borneo: Deforestation and Conservation

  • Significant deforestation began in the 1970s.
  • Known for high biodiversity and dense tree cover.
  • Experiences rainfall throughout the year (January to December).
  • Hot months are typically April and May.
  • A conservation plan is in place to protect 250,000 km² of forest.

Bangladesh: Cyclone Alia (2009) and Flood Risk

  • Cyclone Alia (Category 1) struck on May 25, 2009.
  • Impact: 3 million affected, 179 deaths, and 500,000 people left homeless.
  • Economic damage estimated at $40.7 million.
  • The region is highly prone to flooding, monsoon rains, and flash floods.

Great Barrier Reef, Australia: Scale and Threats

  • Dimensions: Approximately 30,000 km long and 65 km wide.
  • Features: Includes 900 islands and 400 species of coral.
  • Primary threat: Climate change.

Major Rivers and Delta Systems

Mississippi River: Economic Significance

  • Length: 3,734 km.
  • Economic output: Generated $400 billion in 2015.
  • Provides highly fertile land for agriculture.
  • Tourism: Attracts 11 million tourists, generating $1.2 billion annually.
  • Managed by infrastructure such as dams and artificial levees.

Mekong Delta, Vietnam: Agricultural Powerhouse

  • Sediment deposits extend the shoreline by 80 meters per year.
  • The sediment is crucial for good farming soil.
  • 90% of Vietnam's rice production originates from this soil.
  • Exports: 6 million tons annually, valued at $3 billion.

Geohazards: Japan Earthquake (2011)

  • Occurred in 2011 at the boundary between the Eurasian, Pacific, and Philippine plates.
  • Magnitude: 9.1.
  • Resulted in a tsunami with waves reaching 10 meters.
  • Casualties: Approximately 18,000 deaths.
  • Economic Cost: $232 billion in damages.

Development and Globalization

Nike: Global Production Model

  • Headquarters: Beaverton, Oregon, USA.
  • Manufacturing: Operates 15 factories in China, utilizing cheap labor.

Brazil's Economic Growth Drivers

Brazil has experienced significant growth over the past 20 years, despite poorly enforced health and safety regulations.

  • In 2010, the economy grew by 7.5%.
  • Growth is driven by a varied economy across many industrial sectors.
  • Factors attracting investment include foreign investment, low taxes, cheap land, grants, and loans.
  • A large, wealthy population contributes by spending money on goods.

Food Production and Security

Horn of Africa: Causes of Food Shortages

  • Civil war and political instability.
  • Widespread illness.
  • Severe droughts.
  • Lack of suitable soil for crops.

Bangladesh: Agricultural Strengths and Challenges

  • Half of the 161 million population works in agriculture.
  • Benefits: Favorable climate, reliable rainfall, and fertile soil.
  • Challenge: Suffering from increasing world commodity prices.
  • Mitigation: Government is investing in irrigation systems.

Sarawak, Malaysia: Palm Oil Production

  • Represents 10% of Malaysia's total agricultural output.
  • Conditions: High temperatures and high rainfall (tropical forest environment).
  • Issue: Tropical forest deforestation driven by palm oil production.
  • Economic Impact: Generates significant revenue and relies on low-paid labor.
