The Ganges River Basin

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.

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.

‘The Ganges: Cultural, Economic, and Environmental Importance’ is a geographical, cultural, economic, and environmental interpretation of the Ganga River. The Ganga River originates from Gaumukh- situated in the high Himalaya, flows through the world’s biggest fertile alluvial plain, and inlets into the Bay of Bengal at Ganga Sagar. It makes a unique natural and cultural landscape and is believed to be the holiest river of India. The Hindus called it ‘Mother Ganga’ and worship it. The towns/cities, situated on its bank, are world-famous and are known as the highland and valley pilgrimages. The water of the Ganga is pious, and the Hindus use it on different occasions while performing the rituals and customs. This book is unique because no previous study which presents a complete and comprehensive geographical description of the Ganga has been composed. This book presents the historical and cultural significance of the Ganga and its tributaries. Empirical, archival, and observation methods were applied to conduct this study. There are a total of 10 chapters in this book such as ‘Introduction’, ‘the Ganga Basin’, ‘Geography of the Ganga Basin’, ‘the Ganges System: Ganga and its Tributaries’, ‘Ganga between Gaumukh and Uttarkashi’, ‘the Major Cultural Towns’, ‘Major Fairs and Festivals’, ‘Economic Significance of the Ganga’, ‘Environmental Issues’, and ‘Conclusions’. The contents of the book are enriched by 89 figures, 15 tables, and substantial citations and references.

There is a plethora of information available on the river Ganga in the form of books, blogs, articles, websites, videos. Unfortunately, most of the information about this famous river is in a scattered form and reproduced from unverified sources. This contributed volume is the first multi-author volume publication on this subject. The River Ganga includes a vast array of topics written by several authors of distinction. Topics include; hydrology, tributaries, water uses, and environmental features such as river water quality, aquatic and terrestrial flora/fauna, natural resources, ecological characteristics, sensitive environmental components and more. Part I gives a basic introduction of the Ganga river. The existing data and available information from various sources has been compiled in a pictorial fashion in the form of cmaps. Its cultural importance with changing times is also discussed. Part II looks at the rich biodiversity of the Ganga Basin. It gives a detailed description of the major floral and faunal biodiversity with special emphasis on the national aquatic animal dolphin and Sunderbans, the largest mangrove wetland in the world. Part III examines ‘The Ganga Water as it flows’. It focuses on the water quality as well as its associated challenges. Part IV looks at the complexities of issues confronting the river ‘Ganga in changing times’ be it snowmelt runoff, river bank erosion hazards and hydropower assessments; how the factors of population, poverty and pollution contribute to the fate of the river. Part IV touches on economic aspects derived from the river such as business opportunities and tourism.

This book deals with environmental effects on both sides of the border between Bangladesh and India caused by the Ganges water diversion. This issue came to my attention in early 1976 when news media in Bangladesh and overseas, began publications of articles on the unilateral withdrawal of a huge quantity of water from the Ganges River through the commissioning of the Farakka Barrage in India. I first pursued the subject professionally in 1984 while working as a contributor for Bangladesh Today, Holiday and New Nation. During the next two decades, I followed the protracted hydro-political negotiations between the riparian countries in the Ganges basin, and I traveled extensively to observe the environmental and ecological changes in Bangladesh as well as India that occurred due to the water diversion. The Ganges, one of the longest rivers of the world originates at the Gangotri glacier in the Himalayas and flows across the plains of North India. Eventually the river splits into two main branches and empties into the Bay of Bengal. The conflict of diversion and sharing of the Ganges water arose in the middle of the last century when the government of India decided to implement a barrage at Farakka to resolve a navigation problem at the Kolkata Port.

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.

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.
