Urban densification is seen as necessary to save land. It happens in fast-growing cities due to population changes, economic needs, and big transport projects. The costs and benefits of denser cities need to be carefully understood, considering environmental, economic, and social effects. Different factors need to be considered to make cities more valuable and fair. Densification is a complex process that needs to be managed at different levels. Monitoring both hard and soft densification is important to prevent overcrowding and maintain city resilience. Policymakers must also think about how densification affects housing affordability.
