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

AbstractPollution in the environment emerges as a legal and technical object on the one hand, and as a repository of social and cultural beliefs on the other. What happens when we trouble the idea that these belong to different domains and think about seemingly divergent meanings of pollution together? In this article, I draw from anti‐caste and anti‐racist work to explore this question. Extending critical urban scholarship on environmental politics, I attend to formations of caste and religion alongside judicial and political discourse on preventing pollution to the river Ganga in North India. In our present moment, on the banks of the sacred river, extremist leaders mobilize regulations to target minoritized Muslim and Dalit communities in Kanpur's leather industry. I argue that the roots of these actions lie in an environmental petition from the mid‐1980s which transformed urban environmental governance in North India, as the court decoupled questions of environmental protection from economic and social justice. I suggest that the analytic of regional racial formations helps us grapple with uneven socio‐spatial landscapes in postcolonial cities and sharpens our understanding of environmental injustices by moving beyond fixed categories of difference.

"This book focuses on governance and management issues in the much publicized 'Ganga Rejuvenation Project', led by the Indian Prime Minister Mr. Narendra Modi. Attempts over the past three decades to clean up and rejuvenate one of the world's greatest rivers have proved futile. The major reasons for the lack of success are absence of long-term planning, poor co-ordination and failure to sustain whatever little infrastructure for water and sewage treatment could be developed. Focusing on these broad aspects, the book explores spaces for better governance through active community participation, knowledge management, prospects of Public-Private-Partnership, e-governance, youth education, waterfront development, lessons from past failures, comparative international analogies, utilization of external aid and global expertise in successful implementation of a sustainable long-term plan for a river basin's integrated development of both the economy and environment. A host of activities, such as, improving pollution monitoring systems, new development plans for tourism enhancement; river dredging and sewering riparian cities are already being carried in the hope of quick results. The Government of India has also appointed a task force for preparation of a long-term strategy. However, substantial knowledge gaps persist especially with regard to governance. This book aims to address the governance and policy issues and will be a very timely contribution to cleaning as well as rejuvenating Ganga, a river that is lifeline of millions of people."--

AbstractUrbanization has severely impacted the world water resources especially the shallow groundwater systems. There is a need of a robust method for quantifying the water quality degradation, which is still a challenge for most of the urban centers across the world. In this study, a highly urbanized region of Ganga basin is selected to critically evaluate commonly used WQIs and compare with fuzzy modeling. A total of 28 water samples were collected from diverse sources (surface and groundwaters) in the vicinity of urban region covering an area of 216 km2 during the premonsoon period. TDS, TH, NO3−, and F− values were found to be above the permissible limits in 57%, 89%, 4%, and 7% samples, respectively. The WQIs (entropy and integrated) outputs were found to be similar with 89% of the samples falling under moderate category. Fuzzy modeling was carried out allowing user-defined weighting factors for the most influential ions, and the output suggested 96% of the samples falling under moderate to excellent categories. Based on the chemical results and considering the lithology of the study area, the geochemical reactions controlling the water quality were deduced. This study outlines a systematic approach of evaluating the overall water quality of an urban region highlighting the merits and limitations of WQIs. It also justifies the immediate need to generate more robust data to achieve the sustainable development goals 6 (clean water and sanitation) and 11 (sustainability of cities and human settlement).
