How did the Bay of Fundy tides create farmland in Nova Scotia?

The fertile agricultural lands along the Bay of Fundy in Nova Scotia were created by reclaiming marshlands from the sea. The bay is famous for having some of the highest tides in the world, which deposit nutrient-rich sediments across the coastal marshes.12

Beginning in the mid-17th century, early French settlers known as the Acadians constructed systems of dikes to control these powerful tidal waters. By building these embankments, the settlers were able to block the saltwater from flooding the low-lying marshes, effectively draining the land and transforming it into productive agricultural soil. This engineering feat allowed for the development of extensive farmland in an area where much of the surrounding terrain is otherwise unsuitable for cultivation.21
