East Melanesia (49,293–28,578 BCE) Vanuatu, Fiji, New Caledonia, central/eastern Solomons

Geographic & Environmental Context

East Melanesia includes Vanuatu, Fiji, New Caledonia, central/eastern Solomons (Guadalcanal–Malaita–Makira–Santa Cruz).

Anchors: Grande Terre reef-lagoon rim (New Caledonia), Vanuatu arc volcanoes, Fiji high islands & Lau passages, Solomon trench/lagoons.

• Remote Oceania islands rising steeply from deep basins; reef-lagoon systems narrower at lowstand; inter-island distances substantial.

Climate & Environmental Shifts

• LGM: cooler SSTs, stronger trades; reduced rainfall; cyclones still episodic.

Subsistence & Settlement

• No humans yet (Remote Oceania was not peopled until the mid-late Holocene, Lapita ~3.5 ka). Ecosystems dominated by seabirds, reef fish, and forest endemics.

Technology / Corridors / Symbolism

• N/A (pre-human).

Environmental Adaptation & Resilience

• Reef/lagoon productivity robust; volcanic soils accumulated under closed-canopy forests.

Transition

• Post-LGM sea rise will build wide back-reef ponds and passes — the future stage for Lapita seafaring dispersals.
