This note was developed by the OECD Centre for Entrepreneurship, SMEs, Regions and Cities (CFE) in collaboration with the OECD Working Party for Urban Policy and the OECD Champion Mayors Initiative for Inclusive Growth. It is an update of the earlier versions released on 27 March and 13 May, which expands the examples of measures taken by cities to respond to COVID-19 and recover from the economic and social crisis. The note provides analysis on issues related to the economic, social and environmental impacts, lessons learned in terms of digitalisation, mobility, density, urban design and collaborative governance, and action-oriented guidance to build back better cities, building on previous work on urban resilience. Short and medium term responses provided by cities are clustered around six categories: i) social distancing; ii) workplace and commuting; iii) vulnerable groups; iv) local service delivery; v) support to business; and vi) communication, awareness raising and digital tools. The note also includes updated information on how cities are progressively exiting the lockdown. Annex A provides more detailed information on long-term city recovery strategies. Annex B provides more detailed information on the inventoried city initiatives during lockdown and exiting. Annex C maps efforts from selected organisations and city networks to collect city responses and foster knowledge and experience sharing.
