Ecological Significance of Riparian Ecosystems: Challenges and Management Strategies examines the current issues related to river ecosystems, their environmental importance, pollution issues and potential management strategies. The book is divided into 4 key themes: Basics of river ecosystem, Natural phenomenon of river ecosystem, Human-induced problems of river ecosystem, and Management measures for the river ecosystem. Through these four themes, the contributors present both practical and theoretical aspects of river ecosystem in changing climate. An emphasis has been made on the recent research of climate change and its impact on the river ecosystem. River ecosystems have tremendous potential to store CO2, however, with changing climatic and anthropogenic activities, these habitats are under threat, and river ecosystems are losing the very vital service of storing carbon. Unlike well documented terrestrial biodiversity, the biodiversity in aquatic ecosystems is still unrecognized to some extent. Presents an understanding of the biogeochemical processes of river ecosystems achieved by food webs and diverse biogeochemical processes Covers sediment dynamics and nutrient chemistry - hot topics in river ecosystems Includes environmental pollution issues in river ecosystems from various anthropogenic activities

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.

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.

Many decisions on water allocation in river basins are made on economic grounds. Environmental and social benefits of water should also be considered in river basin management, and attempts should be made to value them similarly. This is not a straightforward task and very few studies have directly addressed this issue to date. In this paper, the Menik Ganga (River) in southern Sri Lanka is used as a case study to attempt and evaluate the costs and benefits of environmental water allocations, referred to as ‘environmental flows™ (EF). In this study, a broad definition of EF is used: the components of EF evaluated include the requirements of the religious festival, the requirements of the Yala National Park, the requirements of the Pilinnawa Coastal Wetland and the requirements of the Yala Fishery Management Area, off the coast. Almost all estimates are based on use values of EF such as marketed goods and recreation. For some components multiple estimates have been attempted. The religious EF requirement is estimated using the cost of alternative water supplies. The benefits of the EF requirement for the Yala National Park are estimated using the forgone value of tourism in the dry season and the benefits of avoiding the Human-Elephant Conflict. The Additional expenditure for the park in the dry season is also presented as another proxy estimate of the benefits of EF. The Benefit Transfer method was used for the Pilinnawa Wetland and grassland due to data constraints. The market prices of lobster and income of chank divers are used as proxies for the economic benefits of EF to the Yala Fishery Management Area. Finally, the cumulative value of the individual components is presented and discussed. The paper intends to stimulate discussion and further research on the complex subject of valuing the social and environmental benefits of water whether it is in the Menik Ganga, elsewhere in Sri Lanka or elsewhere in the world.

This book covers water quality indices (WQI) in depth – it describes what purpose they serve, how they are generated, what are their strengths and weaknesses, and how to make the best use of them. It is a concise and unique guide to WQIs for chemists, chemical/environmental engineers and government officials. Whereas it is easy to express the quantity of water, it is very difficult to express its quality because a large number of variables determine the water quality. WQIs seek to resolve the difficulty by translating a set of a large number of variables to a one-digit or a two-digit numeral. They are essential in communicating the status of different water resources in terms of water quality and the impact of various factors on it to policy makers, service personnel, and the lay public. Further they are exceedingly useful in the monitoring and management of water quality. With the importance of water and water quality increasing exponentially, the importance of this topic is also set to increase enormously because only with the use of indices is it possible to assess, express, communicate, and monitor the overall quality of any water source. Provides a concise guide to WQIs: their purpose and generation Compares existing methods and WQIs and outlines strengths and weaknesses Makes recommendations on how the indices should be used and under what circumstances they apply

CLIMATE IMPACTS ON SUSTAINABLE NATURAL RESOURCE MANAGEMENT Climate change has emerged as one of the predominant global concerns of the 21st century. Statistics show that the average surface temperature of the Earth has increased by about 1.18°C since the late 19th century and the sea levels are rising due to the melting of glaciers. Further rise in the global temperature will have dire consequences for the survival of humans on the planet Earth. There is a need to monitor climatic data and associated drivers of changes to develop sustainable planning. The anthropogenic activities that are linked to climate change need scientific evaluation and must be curtailed before it is too late. This book contributes significantly in the field of sustainable natural resource management linked to climate change. Up to date research findings from developing and developed countries like India, Indonesia, Japan, Malaysia, Sri Lanka and the USA have been presented through selected case studies covering different thematic areas. The book has been organised into six major themes of sustainable natural resource management, determinants of forest productivity, agriculture and climate change, water resource management and riverine health, climate change threat on natural resources, and linkages between natural resources and biotic-abiotic stressors to develop the concept and to present the findings in a way that is useful for a wide range of readers. While the range of applications and innovative techniques is constantly increasing, this book provides a summary of findings to provide the updated information. This book will be of interest to researchers and practitioners in the field of environmental sciences, remote sensing, geographical information system, meteorology, sociology and policy studies related to natural resource management and climate change.

Research Paper (postgraduate) from the year 2014 in the subject Environmental Sciences, grade: 8.5, Indian Institute of Technology Roorkee (IIT Roorkee), course: M.Tech, language: English, abstract: There has been necessary to assess the cumulative effects of pollution Sources on river rather only assessment of each human activity and project in isolation. Based on availability of data and time constraint, study of three valued environmental components river water quality, river flow and fluid plain was carried out. This study aims for assessing the cumulative impacts of point Source discharges in river Ganga catchment from Haridwar to Garhmukteshwar (160 km) on these valued environmental components by using different methods such as for water quality, water quality modeling software QUAL2K, and for river flow, modified tenant and flow duration curve shifting methods for the assessment of environmental flow in river stretch. While for flood plain valued environmental component, qualitative method (matrix method) have been used for assessment of cumulative impact of various activities on flood plain VEC. The result shown that QUAL2K model simulation for future prediction during non-monsoon period River stretch will be affected due to severe degradation of water quality at various sites. Environmental flow assessment using hydrological methods (modified tennat method and flow duration curve shifting method) revealed that in months of lean flow river flows do not meet the requirement of minimal flow required to maintain the river environment in desirable state. Impacts on flood plain valued ecosystem component as another VEC shows that river flood plain was also severely affected.
