Study Notes: Urbanisation and Global Environmental Challenges

Urbanisation

  • Rapid urbanisation + industrialisation = environmental and social issues.
  • Cities are engines of economic growth.
  • Statistics:
    • In 1950 → 2 megacities
    • In 2000 → 16 megacities
  • Africa has low megacities (lags behind).
  • Asia has 22, Europe 6, Latin America 4, North America 3.
  • Social Impacts of Cities:
    • Negative: slums, pollution, health issues, crime, inequality.
    • Positive: cultural opportunities, better access to education, medicine, employment.

Small & Medium-Sized Towns

  • Small/medium cities account for majority of urban growth.
  • Less attention compared to megacities.
  • +
  • Ask anything

Sustainable Cities

  • Examples include:
    • Energy independence
    • Low-carbon transport
  • Green infrastructure
  • Recycling, composting
  • More public participation

Economic Development

  • Development influenced by environment.
  • Brundtland Report: sustainable development = "meeting present needs without compromising future generations."
  • Issues:
    • Technology can increase or decrease environmental impact.
    • Deforestation, desertification, water scarcity, climate change.
  • Relationship between technology & environment.
  • ↓
  • +
  • Ask anything urbanisation
  • Technology

Mediating Factors

  • Urbanisation
  • Technology
  • Politics
  • Potentially positive/negative effects.
  • Further challenges:
    • Gender inequality
    • Social inequality
    • Corruption
    • Armed conflicts

The Three P's

  • People, Planet, Profit (Improvement).

Gender Inequality

  • Unequal treatment of genders → unpaid work, lower economic potential.
  • Life chances, starting processes differ.
  • +
  • The wage gap
  • Balancing work & private life
  • Example: Hungary → gender inequality is not bad, but issues remain.
  • Main issues:
    • The wage gap
    • Balancing work & private life

Refugees

  • Nigeria & environmental refugees:
    • Groups forced to migrate due to desertification, drought, flooding.
    • No legal status.

Climate Migration

  • Migration due to climate change.
  • Lack of legal status.
  • Causes: drought, flooding, desertification.

Environmental Impacts of War

  • Environmental Impacts of War (content not provided in transcript).

Global Environmental, Social, and Economic Challenges

1) Earth as a Closed System

  • The Earth is a closed system: finite resources, limited growth.
  • Limits of growth → global impact.
  • Key driver for environmental problems:
    • Population growth (global environment under stress).
    • Consumption/Globalisation → climate change, degradation.
  • Formula:
    Impact=Population×Affluence×Technology\text{Impact} = \text{Population} \times \text{Affluence} \times \text{Technology}

2) Population

  • Direct + indirect impact on environment.
  • Population = very important.
  • Inequality + population growth are connected and are root causes of environmental degradation.

3) Rapid urbanisation + industrialisation

  • Rapid urbanisation + industrialisation = environmental and social issues.
  • Cities are engines of economic growth.
