At What Point Managed Retreat? Resilience Building in the Coastal Zone

Call for Submissions

Organized by the Climate Adaptation Initiative at Columbia University’s Earth Institute, this conference will address a range of issues facing coastal communities in the United States and around the world as sea levels rise and coastal flooding becomes more frequent and intense. The science around retreat is still ill-defined, and policy discussions remain contentious. This conference will bring together thought leaders on this topic to advance the science and policy dialogue. Specifically, the conference is intended to be of interest to academics, planners, practitioners, and industry representatives from sectors such as real estate and insurance. Abstracts are welcome from researchers and those involved in policy, planning, or corporate foresight activities. While the primary focus is expected to be on coastal issues, we anticipate additional talks/sessions focused on additional hazards facing diverse regions, such as drought/fire, heat stress, and inland flooding.

Abstract submission deadline: February 1, 2019

Topics to be addressed include:

Which coastlines will be most affected by sea level rise and surge and what are the uncertainties?

  • The physical science basis for identifying locations that are most likely to be subject to future impacts

Hazard, Risk and Vulnerability
How will exposure intersect with the human systems, the built environment, and large populations?

  • Mapping hotspots of economic/social risk and vulnerability
  • Environmental justice and patterns of risk

Societal Responses
What are the costs and benefits of retreat vs. in situ adaptation, and what advances in governance, planning, and private sector investment are needed?

  • The governance of retreat and infrastructure planning in terms of planning, policy, law, and financing
  • Private sector interests and engagement, including real estate markets, lenders, and insurance markets
  • Population movements, both planned and spontaneous
  • Risk communication and behavior

Abstract Guidelines

Abstracts should be in English and approximately 300 words. Please submit here.

Abstract deadline: February 1, 2019

Abstracts addressing one or more of the above themes may be submitted for either oral or poster presentation. All abstracts will be peer reviewed.

Schedule and Registration 

The conference will open with an evening panel on June 19, followed by two days of plenary and concurrent sessions. Please check back soon for a more detailed conference schedule.

Conference registration will be under $200, and the organizers will arrange discounted room blocks in local hotels.

We hope to have funds for a limited number of travel scholarships for early career researchers and developing country participants. More information about this will be announced shortly.

Conference Goals

  • Convene scientists, policy makers and other stakeholders to advance an interdisciplinary dialogue on a topic that has not been explored in-depth.
  • Weigh the costs and benefits of managed retreat from the coastline versus resilience building and/or reinforcement of coastal defenses for communities in a range of contexts ranging from urban to rural, with varying risk levels.
  • Identify best practices and likely policy options for managing coastal retreat in these different contexts, borrowing from best practices globally.

Out of this conference, the organizers plan to develop a policy-oriented article for a leading journal, op-eds for broader audiences, and a distillation of best practices in a white paper for local planners.
