Threats to Australia’s Oceans and Coasts

Why did we undertake this study?

Oceans and coasts provide important ecosystem, livelihood, and cultural values but they are under threat. To respond to these threats (e.g., through policies and management actions), there is a need to first systematically understand and categorise them.

How was it done?

We undertook a systematic literature review of papers addressing threats to Australia’s marine and coastal environments published between 2010-2020. The term “threat” was broadly interpreted to consider all actions that cause harm to the ocean or coasts, from climate change to governance and other socio-poltical factors. Scopus and Web of Science databases were searched using terms: Australia, threat*, coast*, ocean* and marine*; and inclusion and exclusion criteria applied. 226 papers were included in the final review. In each paper, threats were identified and categoried, first into 19 threat categories, and then into three macro categories: (i) threat from use and extraction; (ii) environmental and human induced threats; and (iii) policy and socio-political threats.

What did we find?

Implications

Ocean and coastal management could be improved through greater consideration of cumulative threats. In its absence there is an underestimation of the severity and extent of current and future threats to Australia’s ocean and coasts. More resources should also be devoted to investigating impacts on Indigenous values, which is comparatively under researched.
