Industrial agriculture accelerates saltwater intrusion in Mid-Atlantic farmlands, threatening food security and coastal ecosystems

The Mid-Atlantic's saltwater crisis is rooted in 17th-century Dutch and English drainage projects that converted tidal wetlands to farmland, a pattern repeated globally during colonial expansion. The USDA's post-WWII 'Swampbuster' provisions incentivized further drainage for industrial agriculture, while post-1950 groundwater pumping for irrigation caused land subsidence, worsening inundation. Similar trajectories unfolded in the Netherlands (polders) and Bangladesh, where colonial land policies and Green Revolution agriculture deepened vulnerability.
The Mid-Atlantic's 'ghost forests' are not merely victims of sea level rise but casualties of a colonial-capitalist land regime that treats soil as a resource to be drained, mined, and abandoned.
Industrial agriculture, subsidized by the USDA and enabled by groundwater extraction, has accelerated subsidence and saltwater intrusion, while marginalizing the very communities—Black, Indigenous, and small-scale farmers—who hold the knowledge to adapt. The study's focus on 'natural' processes obscures how these dynamics are engineered by policy and profit, from 17th-century drainage projects to modern corn subsidies. Yet the crisis also reveals a path forward: agroecological transitions, living shorelines, and land reform can reverse the tide, but only if we confront the structural forces that created it. The trickster's lesson is clear—what we call 'progress' often carries the seeds of its own undoing, and the land itself may be the first to remind us.
