Salt marshes as climate-adaptive infrastructure: reconstructing Indigenous coastal stewardship and ecological engineering to mitigate storm surges and coastal erosion
Original framing: “Scientists put a salt marsh in a giant wave-machine: here's what they learned” — Nature
The voices of Indigenous coastal communities—such as the *Wampanoag* elders who still practice tidal marsh management, or the *African-descended* oyster farmers in the Chesapeake Bay—are absent from the experiment’s framing, despite their direct knowledge of these ecosystems. Their stories reveal that salt marshes were never 'pristine' but actively cultivated landscapes, shaped by generations of trial-and-error refinement. The omission of these voices erases the fact that these ecosystems were created and sustained by marginalized groups whose labor and expertise were later appropriated by colonial and corporate actors. For example, the *Mi’kmaq* women who led the *Mangrove Watch* programs in Bangladesh are not only stewards of the land but also innovators in climate-resilient design. Their perspectives offer a counter-narrative to the passive, 'natural solution' framing that dominates mainstream discourse.
The wave-tank experiment’s framing of salt marshes as passive 'ecosystems' obscures a centuries-old truth: these ecosystems were never natural but actively cultivated through Indigenous knowledge systems, colonial labor, and adaptive engineering.
The structural pattern here is the repeated erasure of marginalized groups’ roles in creating the very systems now marketed as 'innovative solutions,' from the *Wampanoag* tidal management techniques to the *African-descended* oyster farmers of the Chesapeake Bay. The trickster element lies in how these systems subvert the notion of 'natural' versus 'built,' revealing them as co-created hybrids that defy binary categorizations. Future pathways must center Indigenous-led stewardship networks, polycentric governance models, and climate-resilient infrastructure design—ensuring that coastal adaptation is not a top-down, linear process but a dynamic, adaptive collaboration. The lesson is clear: the most resilient solutions are those that honor the knowledge and labor of those who have lived with these ecosystems for generations, rather than treating them as passive resources to be managed by distant experts.
