Mangroves help fight climate change but they’re at serious risk from its effects. That’s one of the findings from a study of a massive mangrove dieback that occurred in late 2015.
Local fishermen reported mangroves were dying along hundreds of kilometres along the Gulf of Carpentaria coastline, an area known for its barramundi fishing and high value commercial fisheries.
This caught the attention of Dr Damien Maher of Southern Cross University, who is interested in the chemistry of mangroves—how they store carbon in their soils, remove planet-warming nitrous oxides from the atmosphere, and neutralise ocean acidification by releasing alkaline chemicals into nearby waters.

Opportunities for alternative livelihoods in fishing communities in Indonesia are being investigated by a team of Indonesian and Australian scientists.
They’re working to understand fisheries and the options for women in coastal areas, while reducing the pressure on targeted marine resources.
Small-scale fisheries are an important source of food security and income in developing countries. Many are also growing into international exporters, but they can place a huge strain on fish populations.

Local fishermen in Indonesia are catching less fish. Whatever the reason, it is a significant problem for those who live on small islands in particular, as fish make up about 90 per cent of the protein they eat.
A team of Indonesian and Australian social scientists is looking at how communities adapt to these changes.
Initially, in a pilot project study financed by the Australia Indonesia Centre, the researchers are examining whether there is a link between fishing productivity and feelings of food insecurity in the small islands off Kai Kecil, and if so, whether a weakening of local management of fish populations and a rise in intercommunity conflicts over fish resources play a role.
