Flood protection in the Brahmaputra's floodplains began rather late and was implemented precisely to protect the important commercial crop of jute. To begin with, in the early twentieth century, after a long wait and much speculation, action was finally taken to make the Brahmaputra's floodplains more productive to the British Empire. Soon the commercial production of jute began in the floodplains. This article explains how the Brahmaputra's floodplains were converted into the British empire's eastern-most jute frontier. The article also explains the political economy of flood management in Assam in the second half of the twentieth century. Further, explaining the shifting relations between state, capital, and floodplain, the article shows how these schemes achieved only partial success and at the cost irreversible ecological damage.
