New in paperback. Hardcover was published in 2023. Desert islands are the focus of intense geopolitical tensions in East Asia today, but they are also sites of nature conservation. In this global environmental history, Paul Kreitman shows how the politics of conservation have entangled with the politics of sovereignty since the emergence of the modern Japanese state in the mid-nineteenth century. Using case studies ranging from Hawaii' to the Bonin Islands to the Senkaku (Ch: Diaoyu) Isles to the South China Sea, he explores how bird islands on the distant margins of the Japanese archipelago and beyond transformed from sites of resource extraction to outposts of empire and from wartime battlegrounds to nature reserves.
