The Australian Defence Force, together with military forces from a number of western democracies, have for some years been seeking out and killing Islamic militants in Iraq, Syria and Afghanistan, detaining asylum seekers for periods at sea or running the judicial systems of failed states. It has also been ready to conduct internal security operations at home. The domestic legal authority cited for this is often the poorly understood concept of executive power, which is power that derives from executive and not parliamentary authority.

Despite the difference in their populations and political status, New Caledonia and Papua New Guinea have comparable levels of economic dependence on the extraction and export of mineral resources. For this reason, the costs and benefits of large-scale mining projects for indigenous communities has been a major political issue in both jurisdictions, and one that has come to be negotiated through multiple channels at different levels of political organisation.

Human Ecology Review is a semi-annual journal that publishes peer-reviewed interdisciplinary research on all aspects of human–environment interactions (Research in Human Ecology). The journal also publishes essays, discussion papers, dialogue, and commentary on special topics relevant to human ecology (Human Ecology Forum), book reviews (Contemporary Human Ecology), and letters, announcements, and other items of interest (Human Ecology Bulletin).

International Review of Environmental History takes an interdisciplinary and global approach to environmental history. It encourages scholars to think big and to tackle the challenges of writing environmental histories across different methodologies, nations, and time-scales. The journal embraces interdisciplinary, comparative and transnational methods, while still recognising the importance of locality in understanding these global processes.

Exploring the Earth under the Sea brings to life the world’s largest and longest-lived geological research program, which has been drilling over many decades at many locations deep below the ocean floor to recover continuous cores of sediment and rock. Study of these materials has helped us understand how the Earth works now, how it has worked in the past and how it may work in the future. The cores are a wonderful source of information on the dynamic processes that form and reform the Earth, both beneath the ocean and on land.

Learning from Fukushima began as a project to respond in a helpful way to the March 2011 triple disaster (earthquake, tsunami, and nuclear meltdown) in north-eastern Japan. It evolved into a collaborative and comprehensive investigation of whether nuclear power was a realistic energy option for East Asia, especially for the 10 member-countries of ASEAN, none of which currently has an operational nuclear power plant.
