Theme Forum - Think Big: 2050 City Megagrowth — Assessing and Addressing the Impacts - Part I

  • Presenter(s): Ahmed Sanda, Garry Middle, Peter Nelson, Weston Fisher, Julian Baskin, Yaw Amoyaw-Osei, Bryony Walmsley

    Recorded: 3 MAR - 27 MAR 2023

    Facilitator(s): Heather M. H. Goldstone, Woodwell Climate Change Research Center

    This forum is the second of our Think Big series, and reviews the potential impacts of megacity urbanization to 2050 and beyond on climate as well as other planetary boundary issues. It also examines potential preferred alternatives for mitigating these impacts through IA processes, particularly Strategic Environmental and Social Impact Assessment and long-term Cumulative Effects Assessment (CEA). We are designing each session to be on topics/issues of interest to general audiences, IA practitioners, urban and regional planners (and hopefully policymakers). 

    Two pre-recorded panel presentations were released in March 2023, followed by this 90-min recording of the live panel discussion with real-time Q&A with panelists and attendees.
