This paper explores the shaping of Bangladesh's southern coastal region, often framed as the most climate vulnerable place in the world, as a zone of climate crisis. As rising waters threaten communities inhabiting the low-lying coastal islands scattered across the deltaic plain, many within the government and donor community have identified shrimp aquaculture as a principal adaptation strategy. Shrimp aquaculture is integral to the dynamics of what I call anticipatory ruination, a discursive and material process of social and ecological destruction in anticipation of real or perceived threats. I elaborate anticipatory ruination as a process that both responds to and produces Bangladesh's climate crisis. I use this concept to explore not only the dynamics taking place in Bangladesh's delta region, but also the ways in which climate crisis is constituted more broadly.
