Our recent report identified how to make aquaculture – including shrimp and seaweed farming – more sustainable for Indonesians and for the environment.
Tidal marshes can build up their soil to keep pace with sea-level rises – up to a point. It turns out the point when the marsh is drowned matches the average rise when global warming exceeds 1.5℃.
During a 2015 heat wave, scientists watched as a coral reef died before their eyes. By the end of the century, almost all the world’s corals will be gone if climate change continues at this pace.

Empatheatre’s latest production is more than a play about three characters who live near the sea. It’s a model for collective consultation on how to save the ocean.

When we build marinas, ports, jetties and coastal defences we introduce hard structures that weren’t there before, and which reduce the amount of sunlight hitting the water.
Marine protected areas are geographically distinct regions of the ocean that are given special protection under law.

Thousands of hydropower dams are under construction around the world. New research shows that by cutting off sediment flow, these dams can have big ecological effects on far-off bays and deltas.
White sharks’ ability to stay warm in cold water makes them efficient long-range hunters.

Fatal shark bites are very rare. But the stats do suggest that the likelihood of an attack proving fatal is higher in Australia - probably because our waters are home to the “big three” dangerous species.
