Two possible solutions from the problems associated with urban expansion?

1. Implementing smart growth policies: Smart growth policies focus on creating compact, walkable, and transit-oriented communities that reduce urban sprawl and promote sustainable development. By encouraging mixed-use development, preserving green spaces, and investing in public transportation infrastructure, cities can accommodate population growth while minimizing the negative impacts of urban expansion.

2. Promoting infill development: Infill development involves redeveloping vacant or underutilized land within existing urban areas, rather than expanding outward into undeveloped land. By prioritizing infill development, cities can revitalize underutilized areas, reduce the need for new infrastructure, and preserve valuable agricultural and natural lands on the outskirts of the city. This approach can help address the challenges of urban expansion while promoting more sustainable and vibrant urban environments.

1. Encourage compact development. This can be done through zoning regulations that limit the amount of land that can be used for new development, as well as by providing incentives for developers to build high-density projects. Compact development can help to reduce traffic congestion, air pollution, and other problems associated with urban sprawl.
2. Invest in public transportation. Public transportation can help to reduce the number of cars on the road, which can in turn help to reduce traffic congestion, air pollution, and other problems associated with urban sprawl. Additionally, public transportation can make it easier for people to live in urban areas without having to own a car, which can save them money and help to reduce their environmental impact.
