The Long Threshold

A lagoon lies behind a barrier beach — still and interior on one side, open sea on the other. That line is the threshold, and it governs the film.

The work runs along it: fish cages and stake traps, night boats, the morning market; rice, lotus and buffalo on the ground the water leaves; tombs standing on former shorelines, where white sand ridges trace a delta the river has since abandoned; then the dunes, and the surf. The lagoon is quiet almost throughout. The sea is allowed to be loud once, at the threshold itself, and the film falls back to still water afterwards.

The film's subject is an FAO project on this lagoon, which Massimo Sarti led and followed for close to a decade — restoring circulation, forming fisher associations, redesigning stake-trap arrays, replanting mangroves. Its costs are named alongside its results: aquaculture cleared much of the flooded forest, and hard coastal engineering is widely questioned, since interrupting sediment movement can move erosion elsewhere rather than resolve it. The work was not about stopping human activity, but about making it compatible with the life of the lagoon.
