Closing Of The Krishna Basin Irrigation Streamflow Depletion And Macroscale Hydrology

Download or read book Closing of the Krishna Basin: Irrigation, streamflow depletion and macroscale hydrology written by Biggs, Trent, Gaur, Anju, Scott, C., Thenkabail, Prasad, Gangadhara Rao, Parthasaradhi, Gumma, Murali Krishna, Acharya, Sreedhar, Turral, Hugh and published by IWMI. This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discharge from the Krishna River into the ocean decreased by 75 percent from 1960-2005, and was zero during a recent multi-year drought. This paper describes the physical geography and hydrology of the Krishna Basin, including runoff production and a basic water account based on hydronomic zones. More than 50 percent of the basin’s irrigated area is groundwater irrigation, which is not currently included in inter-state allocation rules. Future water allocation will require inclusion of the interactions among all irrigated areas, including those irrigated by groundwater and surface water.

Download or read book Water Accounting written by Jayne M. Godfrey and published by Edward Elgar Publishing. This book was released on 2012 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This groundbreaking book examines the role that water accounting can play in resolving economic, environmental and social issues. One of the most pressing global issues of the 21st century is the scarcity of water to ensure economic, environmental and social sustainability. In addressing the issue through policy and management, access to high quality information is critically important. But water scarcity has many implications, and it is possible that different reporting approaches, generally called water accounting systems, can be appropriate to addressing them. In this key book, international experts respond to the question: what role can water accounting play in resolving economic, social and environmental issues at individual, organizational, industry, national and international levels? They explore how various forms of water accounting are utilized and the issues that they address. Academics and postgraduate students interested in water scarcity and accounting will find this book invaluable. Policymakers in all areas relating to water as well as environmentalists, water industry managers and water lawyers will find plenty of important insights in this essential resource.

Download or read book Water Resources Planning and Management written by R. Quentin Grafton and published by Cambridge University Press. This book was released on 2011-02-17 with total page 801 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water is an increasingly critical issue at the forefront of global policy change, management and planning. There are growing concerns about water as a renewable resource, its availability for a wide range of users, aquatic ecosystem health, and global issues relating to climate change, water security, water trading and water ethics. This handbook provides the most comprehensive reference ever published on water resource issues. It brings together multiple disciplines to understand and help resolve problems of water quality and scarcity from a global perspective. Its case studies and 'foundation' chapters will be greatly valued by students, researchers and professionals involved in water resources, hydrology, governance and public policy, law, economics, geography and environmental studies.

Download or read book Evaluation of historic, current and future water demand in the Olifants River Catchment, South Africa written by McCartney, Matthew P., Arranz, Roberto and published by IWMI. This book was released on 2007 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water resource development has played a significant role in the expansion of agriculture and industry in the Olifants River Catchment. However, currently water deficit is one of the major constraints hampering development in the catchment; both the mining and agricultural sectors are producing below optimal levels because of their reliance on insufficient supplies. In this study, the Water Evaluation and Planning (WEAP) model was used to evaluate scenarios of historic, current and future water demand in the catchment. For each scenario, the WEAP model was used to simulate demand in five different sectors (rural, urban, mining, commercial forestry and irrigation) over a 70-year period of varying rainfall and hydrology. Levels of assured supply were estimated for each sector and the economic cost of failing to provide water was predicted. For the future scenarios, the impact of infrastructure development and water conservation measures were assessed. The study illustrates how a relatively simple model can provide useful insight for resource planning and management.

Download or read book Agricultural water management in a water stressed catchment: Lessons from the RIPARWIN Project written by McCartney, Matthew P., Lankford, B. A., Mahoo, H. and published by IWMI. This book was released on 2007 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the face of growing water stress and increasing concerns over the sustainability of water use, Tanzania has, in common with many other countries in Africa, focused largely on the development of more integrated catchment-wide approaches to water management. In the Great Ruaha River Basin, considerable effort has gone into increasing water productivity and the promotion of mechanisms for more efficient allocation of water resources. Over a period of five years, the RIPARWIN project investigated water management in the basin and evaluated the effectiveness of some of the mechanisms that have been introduced. The study findings are relevant to basins in developing countries where there is competition for water and irrigation is one of the main uses.

Download or read book Changing consumption patterns: Implications on food and water demand in India written by Amarasinghe, Upali A., Shah, Tushaar, Singh, Om Prakash and published by IWMI. This book was released on 2007 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing income and urbanization are triggering a rapid change in food consumption patterns in India. This report assesses India’s changing food consumption patterns and their implications on future food and water demand. According to the projections made in this study, the total calorie supply would continue to increase, but the dominance of food grains in the consumption basket is likely to decrease by 2050, and the consumption of non-grain crops and animal products would increase to provide a major part of the daily calorie supply. Although the total food grain demand will decrease, the total grain demand is likely to increase with the increasing feed demand for the livestock. The implications of the changing consumption patterns are assessed through consumptive water use (CWU) under the assumptions of full or partial food self-sufficiency.

Download or read book Peri-urban Water and Sanitation Services written by Mathew Kurian and published by Springer Science & Business Media. This book was released on 2010-08-17 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 2.6 billion people in the developing world lack access to safe water and sanitation service. The Millennium Development Goal’s (MDG) target is to halve the number of people without access to a sustainable source of water supply and connection to a sewer network by 2015. That target is unlikely to be met. If there is anything that can be learnt from European experience it is that institutional reform occurs incrementally when politically enfranchised urban populations perceive a threat to their material well-being due to contamination of water sources.
