Review Questions

• How does urbanization contribute to the growth of megacities and what implications does this have for urban planning?
  • Urbanization drives people from rural areas into cities seeking better job opportunities and living standards. This influx can lead to rapid population growth in urban centers, resulting in megacities. The implications for urban planning include the need for expanded infrastructure, housing development, and public services to accommodate the increasing population while ensuring sustainability.
• Discuss the socio-economic challenges faced by megacities and how they affect the quality of life for residents.
  • Megacities often experience socio-economic challenges such as high unemployment rates, income inequality, and inadequate housing. These factors contribute to the growth of slums where many residents live in poor conditions without access to basic amenities. Such challenges significantly impact the quality of life for residents as they struggle with issues like health care access, education, and safety.
• Evaluate the importance of sustainable development practices in managing the growth and impact of megacities on their environments.
  • Sustainable development practices are crucial in managing megacity growth as they aim to balance economic needs with environmental protection. Implementing strategies like efficient public transport systems, waste management solutions, and green spaces can help mitigate issues such as pollution and resource depletion. As megacities expand, integrating sustainability into urban planning becomes vital for creating livable environments that can support future generations.
