Review Questions

• How do megacities reflect the process of urbanization and state formation?
  • Megacities exemplify urbanization through their explosive growth and increasing population density as people migrate from rural areas seeking opportunities. This migration not only boosts city populations but also leads to state formation as governments create policies and infrastructures to manage these expanding urban areas.

These issues necessitate effective urban governance strategies to address the needs of diverse populations. The pressure on public services such as transportation, healthcare, and education can lead to increased social tensions and demands for reform, highlighting the complexities of managing such large urban environments.
• Evaluate the implications of megacities on global economic trends and environmental sustainability efforts.
  • Megacities significantly influence global economic trends due to their concentration of resources and labor markets. Their role as economic hubs drives innovation and investment but also exacerbates environmental issues such as pollution and waste management challenges. As a result, addressing sustainability in megacities is critical for global efforts to combat climate change while ensuring equitable development. The successful implementation of sustainable practices in these urban centers can serve as models for cities worldwide facing similar challenges.
