Left to Live and Die: Resource Security and the Biopolitics of Land Stockpiling in China

Antipode, EarlyView.
Abstract Beginning in 2007, the Chinese state used liberalising policy and funding to encourage the expansion of large‐scale grain farming. Despite this support, many of the new farms have struggled financially and folded. Drawing on Foucauldian biopolitics and resource security literature, I argue that, with modernised agriculture, the state primarily

An exploration of market mechanisms to the wicked problem of space debris 太空垃圾棘手问题的市场机制探究 Una exploración de los mecanismos del mercado para resolver el complejo problema de los desechos espaciales

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...
