Question 1: What is a Megacity?

Answer: A Megacity is an urban area with a population of over 10 million people.

Question 2: Define urbanization.

Answer: Urbanization is the increase in the proportion of people living in urban areas.

Question 3: What is infrastructure?

Answer: Infrastructure includes the basic physical systems and services such as transport, water supply, and electricity.

Question 4: Name one environmental challenge faced by Megacities.

Answer: Air pollution.

Question 5: Give an example of a Megacity in Asia.

Answer: Tokyo.

Question 1: Which continent has the highest number of Megacities?

Answer: Asia

Question 2: Name two factors that contribute to rapid urban growth in Megacities.

Answer: Rural-urban migration and natural population increase.

Question 3: What is the primary cause of traffic congestion in Mumbai?

Answer: High population density and inadequate transport infrastructure.

Question 4: Describe one environmental problem associated with Lagos.

Answer: Flooding due to poor drainage systems.

Question 1: Based on the Lagos case study, identify two major challenges the city faces.

Answer: Overcrowding and inadequate infrastructure.

Question 2: Explain how rapid population growth in Lagos impacts housing availability.

Answer: Rapid population growth leads to increased demand for housing, resulting in overcrowded slums and informal settlements.

Question 3: Analyze the effects of pollution in Lagos on public health.

Answer: Pollution causes respiratory problems, waterborne diseases, and increased healthcare costs among residents.

Question 4: Evaluate the effectiveness of Lagos' current transport development plans.

Answer: Current plans aim to improve road networks and expand public transport, but challenges remain due to rapid urban growth and funding constraints. While some projects have eased congestion temporarily, long-term sustainable solutions require comprehensive planning and investment.

Question 1: Explain why rural-urban migration contributes to the growth of Megacities like Mumbai.

Answer: Rural-urban migration occurs as people seek better employment opportunities, education, and healthcare in cities. This influx increases the urban population, leading to rapid growth and expansion of Megacities.

Question 2: Analyse the patterns of population distribution within a Megacity such as Tokyo.

Answer: Population distribution in Tokyo is concentrated in central districts with high-density housing, while suburbs have lower densities. Factors include proximity to economic hubs, transport links, and availability of services.

Question 3: Explain the reasons for environmental degradation in rapidly growing Megacities.

Answer: Environmental degradation results from high levels of pollution, deforestation for urban expansion, waste disposal issues, and increased energy consumption.

Question 1: To what extent are current strategies effective in managing urban challenges in Megacities? Consider examples like Mumbai or Lagos.

Answer: Current strategies such as infrastructure development, slum upgrading, and public transport expansion have shown some success in alleviating certain issues. However, rapid urban growth often outpaces planning efforts, and challenges like pollution, traffic congestion, and informal settlements persist. A balanced approach involving sustainable planning, community involvement, and investment is necessary for more effective management.

Question 2: Evaluate the social and environmental impacts of rapid Megacity growth.

Answer: Rapid growth can lead to improved economic opportunities and cultural diversity but also causes social issues like inequality, housing shortages, and strain on services. Environmentally, it results in pollution, habitat loss, and resource depletion. Sustainable development strategies are essential to mitigate these impacts while maximizing benefits.
