Review Questions

• How does urbanization contribute to the formation and growth of megacities?
  • Urbanization plays a crucial role in the formation and growth of megacities as it involves the movement of people from rural areas to urban centers in search of better job opportunities and living standards. This influx leads to population surges in cities, crossing the 10 million mark necessary to classify them as megacities. Additionally, urbanization can drive economic development but also brings challenges like inadequate infrastructure and housing shortages.
• Discuss the socio-economic challenges faced by megacities as they continue to expand.
  • As megacities expand rapidly, they face numerous socio-economic challenges, including severe overcrowding, rising levels of poverty, and the proliferation of slums. These issues can lead to significant disparities in access to services such as healthcare, education, and clean water. The demand for jobs often outstrips supply, resulting in high unemployment rates that further exacerbate social inequalities. Addressing these challenges requires innovative policies and sustainable urban planning.
• Evaluate the implications of megacity growth on global patterns of migration and urban planning.
  • The growth of megacities significantly influences global migration patterns as individuals from rural areas or less developed regions seek opportunities in these urban centers. This influx can alter demographic trends and create multicultural environments that present both opportunities and challenges. Urban planning must adapt to accommodate this rapid growth by integrating sustainable practices that address environmental concerns while providing adequate housing and infrastructure. The interplay between migration trends and urban development shapes not just local policies but also international approaches to urbanization.
