Optimal marsh restoration in barrier-backbarrier systems

Projected rates of relative sea-level rise may drive the migration of barrier islands landward “squeezing” backbarrier marshes. Therefore, barrier island migration alters the ecosystem service provision by barrier-backbarrier systems. How should we respond to these changes if at all? Focusing on the value of blue carbon in barrier-backbarrier systems, we explore whether dynamic marsh restoration policies can generate net benefits for society.
