Open SESAME: A Social-Ecological Systems framework for collaborative Adaptive Management and Engagement in coastal restoration and climate adaptation.

Abstract

The successful implementation and sustainability of many marsh restoration efforts, including coastal adaptation to buffer inundation and mitigate sea level rise, often hinges upon support from surrounding human communities. Yet, stakeholder engagement in these projects remains relatively undervalued and underutilized. We present the Social-Ecological Systems, Adaptive Management, and Engagement (SESAME) framework that provides reciprocal connections between the human and ecological components of restoration efforts and the resulting management and engagement needs. We built and describe this framework through discussion of two case studies of coastal restoration efforts in southern New England salt marshes. The first case study focuses on the use of sediment placement to increase the elevation of the surface of a drowning marsh in Rhode Island as an interim measure to protect against sea level rise. The second case study describes the use of living shorelines for erosion mitigation on a salt marsh in Massachusetts. These cases included significant partner and stakeholder engagement and provided important lessons learned for practical implementation of the SESAME framework. Valuable lessons included the need for engagement throughout the entirety of the process, specific clarification of roles within the restoration efforts, and flexibility in implementation and goal setting.
