Climate change puts the edge between land and sea in sharp relief; sea level rise is essentially a condition of drifting littoral edges.As rising seas threaten to encroach on land-based territories, cities and nations have responded by attempting to fix the edge at a moment in time, blocking the sea's insidious creep.Atolls formed by coral reefs are mobile, living geographies, which resist attempts to harden their perimeter through structures such as seawalls.We explore how ideas and imaginaries associated with the "edge" between sea and land in the atoll-nation of Tuvalu illustrate competing "riskscapes" and objectives associated with the actors involved.This essay explores this interplay between politics, aid, technocratic solutions, media representations, global aspirations, local ambitions, and climate risk in Tuvalu through an examination of past/future seawalls and other proposals (realized and unrealized) for controlling atoll edges.Through the cases, we seek to re-politicize the edge, unpacking the difficulties surrounding adaptation issues in small-island states, and explore alternative models of "resilient edges" for atoll-dwellers living with climate changes.
