r travel. This reduction in demand provides an opportunity to test new transportation policies and infrastructure that promote sustainable modes of transportation such as walking, cycling, and public transportation. Cities can analyze the impact of reduced traffic on air quality, carbon emissions, and pedestrian safety to identify areas that require improvement.

Land use: The pandemic has also led to changes in land use as many commercial and retail spaces have been vacated due to the economic downturn. Cities can use this opportunity to test new zoning regulations that encourage mixed-use development and increase the availability of affordable housing. This can help reduce urban sprawl, promote walkability, and improve access to public transportation.

Energy consumption: The pandemic has also led to changes in energy consumption patterns as people started spending more time at home. This provides an opportunity to test new energy-efficient technologies and building practices that can help reduce energy consumption in buildings. For example, cities can analyze the impact of increased use of natural light and ventilation on energy consumption to identify areas that require improvement.

In conclusion, the COVID-19 pandemic provides a unique opportunity to test sustainable densification practices that can help cities become more resilient and sustainable in the long term. By analyzing the impact of the pandemic on transportation patterns, land use, and energy consumption, cities can identify areas that require improvement and test new policies and practices to promote sustainable densification.
