MEGA-ECO: A Symposium on Very Large-Scale Landscape Projects

For nearly a century, a new breed of landscape infrastructure megaproject has gone unrecognized, and is now proliferating, according to the organizers of a public symposium at the University of Pennsylvania Stuart Weitzman School of Design set for October 5, 2023. These projects are designed to address biodiversity loss, land degradation, and climate change while improving living conditions for the Earth’s eight billion human inhabitants. Representing trillions of dollars in potential investments, can they deliver the ecological transformation they promise?

MEGA-ECO: A Symposium on Very Large-Scale Landscape Projects brings together designers and land managers for ecological restoration megaprojects in China, Pakistan, Brazil, Africa, Korea, Saudi Arabia, Canada, and the US to explore cross-border approaches to connectivity, anti-desertification, watersheds, and metropolitan development. They include representatives of the World Wildlife Fund, the International Union for the Conservation of Nature, and the Center for Large Landscape Conservation, among others, who will discuss the Four Major Rivers Restoration Project (China); Forest Conservation in the Heart of the Colombian Amazon; Great Green Wall Initiative (Africa); São Paulo Greenbelt and Biosphere Reserve (Brazil); Sponge Cities Initiative (China); Upper Mississippi River Restoration Program (US); Upscaling Green Pakistan; and Yellowstone to Yukon (North America).

The program opens with a keynote talk by author Tony Hiss, co-creator of the half-earth movement (50x50) and visiting scholar at the Wagner School of Public Service, New York University.


The symposium is organized into four sessions, with presentations from each project representative followed by a discussion with expert panelists:

  1. Keith Bowers, Landscape Architect and Founder, Biohabitats
  2. Dr. Gary Tabor, Founder and Director, Center for Large Landscape Conservation
  3. Dr. Emmanuelle Cohen-Shachem, Nature-based Solutions, Thematic Lead, International Union for Conservation of Nature
  4. David Kuhn, Lead, Corporate Resilience, World Wildlife Fund
  5. Tyra Northwest, Traditional Land Use Lead, Samson Cree Nation, and co-founder, International Buffalo Relations Institute

MEGA-ECO is presented by The Ian L. McHarg Center for Urbanism and Ecology and Penn Global, and is organized by Rob Levinthal, PhD candidate in the Department of City & Regional Planning, and Richard Weller, professor of landscape architecture.

MEGA-ECO builds on the 2019 publication Design With Nature Now, a re-assessment of the legacy of Ian McHarg’s landmark 1969 book Design With Nature which was co-edited by Weller along with Penn faculty members Frederick Steiner, dean and Paley Professor; Karen M’Closkey, associate professor of landscape architecture; and Billy Fleming, Wilks Family Director at The McHarg Center.

The public symposium on October 5 is followed by an invite-only roundtable on October 6. Admission to the symposium is free and open to the public with advance registration.
