After fifty years of aggressive augmentation, reclaimed land now makes up a quarter of Singapore’s total landmass. Cut out of sea, this artificial land aspires to cut the chain of causality: to self-found and so give law to itself (auto-nomos). How to analytically capture that gesture of self-authoring? From what vantage point does one study an object like reclamation whose structure is that of recursion? This is the challenge—at once methodological and theoretical—to which my dissertation responds. I proceed first by asking: what exactly is being reclaimed in reclamation? Why should the creation of “new” land need to be enacted in the idiom of a “re,” that is, as a re-taking, a retrieval, or a return? Though reclamation purports to create land “from sea,” key to this land-making is not saltwater but sand and labor, both of which Singapore imports in vast quantities from its South, East, and Southeast Asian neighbors. Harnessing those flows, reclamation would appear to put the very ground itself in motion. Foreign coastlines are dismantled, ferried piecemeal, then reassembled into new land in Singapore by migrant workers on barges. In the process, land paradoxically becomes chattel. What then becomes of chattel—including certain forms of labor? A tentative answer might be obtained, I argue, by looking to the legal and labor histories that inform this present-day fabrication of mobile land. Thus the dissertation rehabilitates a link between today’s migrant labor and its earlier prefiguration, colonial convict labor, which was first tasked with creating new land in the island’s interior. Just as today’s reclaimed land needs labor’s upkeep to fend off the tides, interior land needed constant servicing to prevent its return to the jungle. Where convict labor’s lot was “imprisonment in transportation, beyond sea, for life,” reclamation workers, confined in vessels, trace an unending circuit between dredge sites at sea and fill sites near land. By situating reclamation within those longer-standing political economies of extraction, I show that mobile land—made here to be eternally remade against rising seas—is not “new” and cannot be claimed, but rather must always be re-claimed, even in the very first instance.
