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.

Chapter 10 provides an overview of the Open approach, focusing on its merits, progress, and prospects and showing how it can be more conducive to sustainable development. It shows that the Open approach is not a passive approach but requires sustained activities along many dimensions, including both flood-proofing and flood-regulating measures. The chapter follows the progression of the Open approach. It discusses the reflection of this approach in the European Union’s Directive on Floods and its implementation. It takes note of country level initiatives in many European countries, such as the Netherlands’ “Room for River” project, that conform with the Open approach. The chapter then examines some recent policy changes in the United States regarding the Mississippi levee system that also reflect the Open approach. It also reviews the progress of the Open approach in other parts of the world.

Chapter 9 presents the Cordon approach, describing its methods, reviewing its spread across the world, and analyzing its consequences. It discusses the general relationship between river channels and their floodplains and explains the nurturing functions that regular river inundations perform. The chapter then outlines the instruments of the Cordon approach, such as embankments, floodwalls, channelization, and canalization. It goes on to explain the relationship between the Cordon and the Polder approaches and offers a classification of cordons into different types. The chapter reviews the consequences of the Cordon approach, distinguishing between those for river channels and for floodplains. It provides an overview of the experience of the Cordon approach in different parts of the world, focusing on the United States, Europe, and India. It also presents two case studies of the Cordon approach: the Mississippi levee system in the United States and the Huang He River embankments in China.

Chapter 2 reviews the origin and spread of the Commercial approach to rivers. It explains the origin of this approach in the first Industrial Revolution, which provided human societies both the commercial motive and the machine power required to undertake large-scale frontal and lateral interventions in rivers. The chapter catalogues various types of frontal intervening structures—including dams, barrages, and weirs—that the Commercial approach deploys to achieve its purpose. The chapter then follows the spread of the frontal version of the Commercial approach across the world, beginning with the developed countries and then the developing countries in Asia, Africa, and Latin America. The chapter ends by providing a statistical summary of the global picture regarding dams and barrages, which are the main instruments of the Commercial approach to rivers.

Chapter 3 examines the adverse effects of the Commercial approach on river morphology, such as fragmentation of rivers, upstream sedimentation, and downstream disfigurations. It demonstrates the “More water, more thirst!” syndrome that this approach creates, leading to exhaustion of rivers and deleterious effects on deltas, estuaries, and the coastal environment. It reviews the broader effects of this approach on the ecology of river basins, including loss of seasonal pulses and emergence of new dangers of catastrophic flooding, waterlogging, salinity, deterioration of soil quality, and damages to the flora and fauna. The chapter also examines the unsuitability of the Commercial approach in the light of climate change, noting GHG emissions from dam reservoirs and increased risks from erratic and greater precipitation. It illustrates the unfair distribution of costs and benefits of the Commercial approach and shows that financial rates of return of projects under the Commercial approach are generally lower than claimed, and the economic rates of return are even lower, if not negative. The chapter also shows how the Commercial approach creates conflicts among co-riparian communities.

Chapter 8 reviews the progress of the Ecological approach across the world, in both developed and developing countries. In the United States, this progress can be seen in both dam removal and river restoration activities, including attempts to resuscitate the Colorado River Delta. In Europe, the progress of the Ecological approach has assumed a comprehensive character, as evidenced by the European Union’s Water Framework Directive (WFD) of 2000. The Ecological approach has made advances in developing countries too, many of which were practicing the pre-industrial variant of the Ecological approach until recently. The Narmada Bachao Andolon of India was a strong manifestation of the Ecological approach. Influenced, in part, by their pre-industrial ecological traditions, many developing countries have now taken such advanced steps as giving rivers and nature constitutional rights to exist and survive and not be disrupted by human interventions. These broader initiatives have provided further impetus for the Ecological approach to spread in developing countries.

Chapter 4 provides a few case studies of rivers to illustrate the consequences of the Commercial approach. These rivers are: the Colorado River of the United States; the Murray-Darling river system of Australia; the Amu Darya and Syr Darya of the former Soviet Union; the Nile River of Africa; and the Indus River of South Asia. It shows that in each case, the application of the Commercial approach has led to river fragmentation and excessive withdrawal of water, leading to exhaustion of rivers, which in turn led to salinity intrusion and erosion, subsidence, and desiccation of the deltas. The ecology of the river basins has been damaged, including loss of aquatic and terrestrial biodiversity. In case of the Amu Darya and Syr Darya Rivers, this damage includes the destruction of the Aral Sea, once considered the second-largest inland waterbody of the world. In each case, the Commercial approach has led to conflicts among co-riparian countries.

Chapter 6 introduces the Ecological approach to rivers that arose in response to the adverse effects of the Commercial approach. It explains the distinction between the pre- and post-industrial Ecological approaches. While the former was a compulsion due to low level of technology, the latter is a choice made to avoid the negative consequences of high level of technology acquired through the Industrial Revolution. The chapter clarifies the relationship of the Ecological approach with the basin-wide approach to rivers. It also shows that the Ecological approach can be viwed as an enlightened anthropocentric view of river, which in practical terms is also compatible with the non-anthropocentric view. The chapter goes on to show that, contrary to the popular perception, the Ecological approach is an active approach, requiring sustained efforts along multiple directions. Instead of negating the role of rivers as a resource, the Ecological approach advocates the use of this resource while preserving the basic role of rivers in maintaining earth’s hydrological cycle and the unique ecologies of their basins. The Ecological approach thereby is more conducive to sustainable development than the Commercial approach.

Chapter 7 shows that the emergence of the Ecological approach to rivers is a part of the broader process of greater recognition of the importance of protection of environment, in general. The huge increase in population and production following the Industrial Revolution led to breaches in planetary boundaries, putting the earth and human civilization in a jeopardy. Since the 1970s there has been growing recognition of this mortal danger, and various initiatives were begun along different directions to confront this danger, many focused on protection of rivers and waterbodies. Among these are the Ramsar Convention of 1971, UN Convention on International Rivers of 1997, and formation and report of the World Commission on Dams in 2000. The rise of the Ecological approach to rivers is a continuation of this process.

Chapter 1 introduces the concepts proposed in the book and gives an overview of the remaining chapters. It first highlights the importance of rivers for the three dimensions of sustainable development, namely economic growth, social development, and environmental protection. The chapter next describes broadly two opposing approaches to rivers, Commercial and Ecological. The former is based on the premise that “Any river water that passes to the sea is a waste,” and encourages impounding and abstraction of river water for various commercial purposes. The later considers carrying precipitation water to the seas as the main function of rivers and discourages interventions that alter significantly volume and direction of river flows. Both Commercial and Ecological approaches have their corresponding frontal and lateral versions. The lateral version of the Commercial approach is the Cordon approach, according to which floodplains should be cordoned off from river channels through construction of embankments. By contrast, the lateral form of the Ecological approach is the Open approach, which advocates keeping floodplains open to river channels for the benefit of both floodplains and river channels.
