Ganges Water Machine

Beyond the dense urbanism of Mumbai (Bombay) or the IT centers of Bangalore and Hyderabad lies the Ganges River basin--today home to over one-quarter of India's billion-plus population--a space historically defined by a mythological constellation of terrestrial sites imbued with celestial significance. Not only is it one of the most densely populated river basins in the world, but it also undergoes dramatic physical changes with the onslaught of the wet monsoon, where over one-meter of rainfall occurs in the span of three months. This book focuses on the intersection of these two observations. It is an atlas of built and unbuilt projects designed to transform the river into a giant water machine. Since the middle of the nineteenth century, this mythical watercourse has functioned as a laboratory to test and build a new civilization around the culture of water. Jointly authored by people and nature, the Ganges River is today a monstrous water machine in which the entire basin became a workshop of human-made experience, defined by a hydrological system best described as a supersurface: a surface engineered from the scale of the soil to the scale of the nation. Everything from diffuse urban projects and green revolutions to colossal public works programs and architectural transformations constitute the genesis of the Ganges Water Machine. Whether to thwart massive peasant uprisings or to redirect monsoonal rains to productive ends, never before has a river that inspired the realization of unbelievable architectural and infrastructural projects received as little scrutiny as the Ganges river basin. Reaching through the very heart of some of India s most densely populated cities, small towns, industrial zones, sacred sites, and mountainous forests, Ganges Water Machine by Anthony Acciavatti, composed of eight years of field and archival research, explores and theorizes the people and infrastructures that shaped this territory. Ganges Water Machine is an atlas of the enterprise to make the Ganges River basin into a highly engineered landscape: it reveals the narratives and explanations that allowed engineers and planners to realize fantasies previously only imaginable on paper or in myth.

The Ganges is one of the most complex yet fascinating river systems in the world. The basin is characterized by a high degree of heterogeneity from climatic, hydrological, geomorphological, cultural, environmental and socio-economic perspectives. More than 500 million people are directly or indirectly dependent upon the Ganges River Basin, which spans China, Nepal, India and Bangladesh. While there are many books covering one aspect of the Ganges, ranging from hydrology to cultural significance, this book is unique in presenting a comprehensive inter-disciplinary overview of the key issues and challenges facing the region. Contributors from the three main riparian nations assess the status and trends of water resources, including the Himalayas, groundwater, pollution, floods, drought and climate change. They describe livelihood systems in the basin, and the social, economic, geopolitical and institutional constraints, including transboundary disputes, to achieving productive, sustainable and equitable water access. Management of the main water-use sectors and their inter-linkages are reviewed, as well as the sustainability and trade-offs in conservation of natural systems and resource development such as for hydropower or agriculture.

Although the Ganges River Basin (GRB) has abundant water resources, the seasonal monsoon causes a mismatch in water supply and demand, which creates severe water-related challenges for the people living in the basin, the rapidly growing economy and the environment. Addressing these increasing challenges will depend on how people manage the basin’s groundwater resources, on which the reliance will increase further due to limited prospects for additional surface storage development. This report assesses the potential of the Ganges Water Machine (GWM), a concept proposed 40 years ago, to meet the increasing water demand through groundwater, and mitigate the impacts of floods and droughts. The GWM provides additional subsurface storage (SSS) through the accelerated use of groundwater prior to the onset of the monsoon season, and subsequent recharging of this SSS through monsoon surface runoff. It was identified that there is potential to enhance SSS through managed aquifer recharge during the monsoon season, and to use solar energy for groundwater pumping, which is financially more viable than using diesel as practiced in many areas at present. The report further explores the limitations associated with water quality issues for pumping and recharge in the GRB, and discusses other related challenges, including availability of land for recharge structures and people’s willingness to increase the cropping intensity beyond the present level.

This book presents an overview of the hydrometeorological and hydrological studies and assists in tackling challenges posed by climate and land use land cover changes. The Ganga River is one of the major living streams on the planet earth and very important river system in India. This holy river is a lifeline for approximately five hundred million people. In the last few decades, River Ganges has been subjected to tremendous pressures with respect to both water quantity and water quality. This situation, already one of the alarming magnitudes, has been further provoked by hydrometeorological changes resulting in droughts, floods and reduced groundwater levels and river flows in addition to the poor river health. Thus, it is imperative to assess the various complexities and possible solutions for better management of River Ganges. This book is a valuable addition to the literature and contributes to research on River Ganges which will help better planning and management of Ganga river basin. The hydrological and hydrometeorological aspects covered in this book help practitioners, researchers, policymakers and other stakeholders.

From a MacArthur "Genius," a bold new perspective on the history of Asia, highlighting the long quest to tame its waters Asia's history has been shaped by her waters. In Unruly Waters, historian Sunil Amrith reimagines Asia's history through the stories of its rains, rivers, coasts, and seas--and of the weather-watchers and engineers, mapmakers and farmers who have sought to control them. Looking out from India, he shows how dreams and fears of water shaped visions of political independence and economic development, provoked efforts to reshape nature through dams and pumps, and unleashed powerful tensions within and between nations. Today, Asian nations are racing to construct hundreds of dams in the Himalayas, with dire environmental impacts; hundreds of millions crowd into coastal cities threatened by cyclones and storm surges. In an age of climate change, Unruly Waters is essential reading for anyone seeking to understand Asia's past and its future.

Greenhouse-induced climate warming increasingly appears to be a reality, and the warming climate will be accompanied by an accelerated sea level rise - as much as 60-100 cm over the next century. What is commonly absent in the discussion of rising sea level, however, is the role played by the subsidence of low-lying coastal areas, which can have a far greater local effect than the eustatic rise of the sea. The combined sea-level rise and land subsidence will almost certainly make the greatest impact on coastal societies in the densely populated regions of southern Asia, but its effects will be felt globally. This volume explores the concepts of sea-level rise and coastal subsidence, both natural and anthropogenically accelerated, in the form of a series of case studies in such diverse locations as Bangkok, Bangladesh, Venice, and the Niger and Mississippi deltas, as well as a discussion of the economic, engineering and policy responses that must be considered if the effects of local sea-level rise are to be mitigated.

A sweeping, interdisciplinary history of the world's third-largest river, a potent symbol across South Asia and the Hindu diaspora Originating in the Himalayas and flowing into the Bay of Bengal, the Ganges is India's most important and sacred river. In this unprecedented work, historian Sudipta Sen tells the story of the Ganges, from the communities that arose on its banks to the merchants that navigated its waters, and the way it came to occupy center stage in the history and culture of the subcontinent. Sen begins his chronicle in prehistoric India, tracing the river's first settlers, its myths of origin in the Hindu tradition, and its significance during the ascendancy of popular Buddhism. In the following centuries, Indian empires, Central Asian regimes, European merchants, the British Empire, and the Indian nation-state all shaped the identity and ecology of the river. Weaving together geography, environmental politics, and religious history, Sen offers in this lavishly illustrated volume a remarkable portrait of one of the world's largest and most densely populated river basins.
