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.
