Cordon approach in a delta

Chapter 11 illustrates the consequences of the Cordon approach through the experience of the Bengal Delta, formed by three great river systems—the Ganges, Brahmaputra, and Meghna. The chapter explains the delta formation process in general, noting the stages through which it progresses. It presents the basic facts regarding the Bengal delta, which now spreads across both Bangladesh and India. The chapter reviews the application of the Cordon approach in both parts of the delta. It notes that the approach received wider application in Bangladesh, which contains the larger and active part of the Bengal Delta. In the process, the approach gave rise to different types of cordons, rural and urban; coastal and inland; and partial and full. The chapter shows that while the specificities differ, the Cordon approach in each case led to separation of the land from the nurturing functions of river overflows, emergence of the new danger of catastrophic flooding, and the nagging problem of waterlogging. The Cordon approach also led to the rise of conflicts, pitting people inside the cordons with those remaining outside, who witnessed aggravation of flooding.
