Long Descriptive Questions with Answers

1. Explain the key challenges that modern cities face in terms of housing and urban development.
   • Answer: Modern cities face a range of challenges in housing and urban development, primarily driven by rapid urbanization. These challenges include a lack of affordable housing, increasing demand due to population growth, and the rise of informal settlements. Gentrification often leads to the displacement of lower-income residents, and housing bubbles can cause financial instability. To address these issues, cities must implement policies that promote affordable housing, ensure equitable development, and regulate real estate markets.
2. Discuss the economic implications of urban sprawl on transportation and infrastructure.
   • Answer: Urban sprawl leads to increased demand for transportation infrastructure, as cities expand beyond their traditional boundaries. This results in higher transportation costs, longer commute times, and more traffic congestion. The need for new roads, public transport systems, and utilities increases the cost of maintaining urban infrastructure. Additionally, sprawl can strain natural resources, reduce urban density, and lead to environmental degradation, creating challenges for sustainable development.
3. How do public transport systems influence economic activity in urban areas?
   • Answer: Public transport systems are critical for facilitating the movement of people and goods within urban areas. Efficient public transport reduces congestion, making cities more accessible and enabling workers to commute efficiently. It also boosts economic activity by connecting neighborhoods with job markets, retail hubs, and cultural institutions. A well-functioning public transport system can attract businesses, increase property values, and promote tourism, making it an essential element of urban economic development.
4. What are the social and economic impacts of income inequality in urban areas?
   • Answer: Income inequality in urban areas can lead to social tensions, reduced social mobility, and economic instability. Low-income residents often face limited access to quality education, healthcare, and housing, exacerbating the cycle of poverty. The wealthy may have greater access to resources, reinforcing economic disparities. The divide between rich and poor neighborhoods can also lead to segregation, reducing social cohesion and contributing to urban unrest. Addressing inequality requires targeted policies aimed at improving access to resources and opportunities for disadvantaged groups.
5. How can cities promote sustainability while addressing the challenges of urbanization?
   • Answer: Cities can promote sustainability by implementing green urban planning strategies, including energy-efficient buildings, renewable energy sources, and sustainable waste management. Encouraging public transport, reducing car dependency, and increasing green spaces also contribute to a sustainable urban environment. Sustainable urban agriculture, water conservation, and environmental protection policies can mitigate the negative effects of urbanization, ensuring that cities grow in an environmentally responsible and resilient manner.
