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 Shifting Waterscapes Explaining Basin Closure in the Lower Krishna Basin South India written by Jean-Philippe Venot and published by IWMI. This book was released on with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progressive agricultural and water development in the Krishna Basin in South India has led to a rising over commitment of water resources and signs of basin closure are apparent during dry periods. As human consumptive uses are approaching the limits of water availability, this report focuses on the Lower Krishna Basin that bears the brunt of any intervention upstream. Capturing the process of basin closure requires an understanding of the political dimension of access to water and the scope for change. As basin closure intensifies the interconnectedness of ecosystems and water users, adjustments and management decisions result in spatial re-appropriation of water and basin-wide strategies for water management and development that start with the definition and the implementation of water allocation mechanisms are increasingly needed.

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 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.

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.

Download or read book Taming the Anarchy written by Tushaar Shah and published by Routledge. This book was released on 2010-09-30 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: In 1947, British India-the part of South Asia that is today's India, Pakistan, and Bangladesh-emerged from the colonial era with the world's largest centrally managed canal irrigation infrastructure. However, as vividly illustrated by Tushaar Shah, the orderly irrigation economy that saved millions of rural poor from droughts and famines is now a vast atomistic system of widely dispersed tube-wells that are drawing groundwater without permits or hindrances. Taming the Anarchy is about the development of this chaos and the prospects to bring it under control. It is about both the massive benefit that the irrigation economy has created and the ill-fare it threatens through depleted aquifers and pollution. Tushaar Shah brings exceptional insight into a socio-ecological phenomenon that has befuddled scientists and policymakers alike. In systematic fashion, he investigates the forces behind the transformation of South Asian irrigation and considers its social, economic, and ecological impacts. He considers what is unique to South Asia and what is in common with other developing regions. He argues that, without effective governance, the resulting groundwater stress threatens the sustenance of the agrarian system and therefore the well being of the nearly one and a half billion people who live in South Asia. Yet, finding solutions is a formidable challenge. The way forward in the short run, Shah suggests, lies in indirect, adaptive strategies that change the conduct of water users. From antiquity until the 1960‘s, agricultural water management in South Asia was predominantly the affair of village communities and/or the state. Today, the region depends on irrigation from some 25 million individually owned groundwater wells. Tushaar Shah provides a fascinating economic, political, and cultural history of the development and use of technology that is also a history of a society in transition. His book provides powerful ideas and lessons for researchers, historians, and policy

This book was released on 2007 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study attempts to examine those unique aspects of interbasin water transfer planning, which are of critical importance to the sustainable water resources development in India. It focuses on the crucial aspect of accurate quantification of surface water availability, which determines the entire feasibility of a water transfer. It also illustrates the impacts of upstream water resources development on the deltas’ environment thus justifying the deltas’ environmental flow requirements. The report targets government departments, research institutions and NGOs – primarily in India and other countries of the region – which are engaged or interested in issues of interbasin water transfer and environmental water management. The research intends to: contribute to the effectiveness of water resources planning and management in India; emphasize the need for urgent improvement of access to hydrometeorological data in the country; and aim to stimulate further debate on water transfers.

Download or read book The lower Krishna Basin trajectory relationships between basin development and downstream environmental degradation written by and published by IWMI. This book was released on 2008 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: Basin water development and rural dynamics in the Krishna Basin have led to a degradation of downstream ecosystems manifesting itself by salinizing soil and groundwater, increasing pollution, disappearing mangroves and desiccating wetlands. Reversing this evolution requires the formal recognition of the environment as a water user in its own right and the implementation of an environmental water provision. This provision should be based on a two-tier allocation system with assured discharges in the irrigation canals of the delta and to the ocean. This will lead to further commitment of water resources but this is needed to reconcile the social, economic and environmental objectives of a sustainable development. Other measures facilitating integrated natural resources management from the local to the basin level are needed too.

Download or read book Trees and water smallholder agroforestry on irrigated lands in Northern India written by Zomer, Robert J., Bossio, Deborah A., Trabucco, Antonio, Yuanjie, Li, Gupta, Diwan C., Singh, Virendra P. and published by IWMI. This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trees are increasingly grown on-farm to supply wood and biomass needs within developing countries. Over the last several decades, within the irrigated rice-wheat growing lands of northern India, fast-growing poplar trees have been planted on tens of thousands of small farms. Recent debate regarding afforestation has raised the issue that water use is often increased when trees are planted. This ongoing debate focuses primarily on afforestation or reforestation of upland and rain-fed agricultural areas, and off-site impacts such as reduced streamflow. Adoption of poplar agroforestry in northern India, in contrast, is occurring in areas where land and water are already intensively used and managed for agricultural production. This study based on farmer survey data, used remote sensing and spatial hydrological modeling to investigate the importance and role of the poplar trees within the agricultural landscape, and to estimate their water use. Overall, results illustrate a potential for addressing the increasing global demand for wood products with trees grown on-farm within irrigated agroforestry systems.
