This book was released on with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the short water supply environment of Pakistan, fanners try to minimize the gap between demand and supply of canal water by extracting groundwater for irrigation purposes. However, saline groundwater upconing may occur in response to fresh groundwater withdrawals from unconfined aquifer underlain by salty groundwater. Skimming well technology can help in control1ing this upconing phenomenon. However, in most cases, the small discharges of such wells cannot be efficiently applied on surface irrigated croplands. Pressurized irrigation systems use smal1 discharge effectively, but the cost and availability of equipment in the local market are the constraints. Root zone salinity is also expected to increase if this skimmed groundwater is used for irrigation purposes, particularly in the absence of proper salinity management practices. To address these issues, International Water Management Institute (lWMI), Water Resource Research Institute (WRRI) and Mona Reclamation Experimental Project (MREP) collaborated to undertake an applied research project on Root Zone Salinity Management Using Fractional Skimming Wells with Pressurized Irrigation. This project was started in March 1999 and concluded in June 2003. The National Drainage Program (NDP), Research Component -WAPDA funded this project

This book was released on 2003-03-03 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Detailed hydro-geological investigations were carried out while implementing SCARPs in the Chaj Doab. These investigations yielded a data set of groundwater quality at different depths of the aquifers (spatial) especially in the SCARP-II saline zone. In MREP area, 138 public tubewells, having strainers from 30-35 m till 60-75 m depth of the aquifer, were installed during the 1970s to help meet the irrigation water demand at farm level. The MREP, who was made responsible for operation and maintenance of these deep tubewells, continuously monitored the performance of these tubewells as well. Therefore, the pumped groundwater quality data (temporal) of these spatially distributed tubewells was also available. This data availability served as a basis for site selection using GIS analysis.The GIS analysis, which was used in classifying different groundwater quality zones, helped in selecting fifteen villages (thirteen in MREP area and two in SCARP-II saline zone) that have hydro-geological potential for installing and operating skimming wells. In these selected villages, preliminary survey was carried out to get information on the farmers' willingness to use skimming well technology. Based on the GIS analysiS and preliminary survey, different sites in six villages (two in SCARP-II saline zone, and four in SCARP-II non-saline zone) were selected to carry out the Diagnostic AnalysiS (DA) for investigating the hydro-salinity and hydro-geological conditions of the aquifer. Based on the DA results, four villages for the Participatory Rural Appraisal (PRA) to assess farmers' practices and perceptions in opting for skimming well technologies.

Book Synopsis Soil Salinity under Irrigation by : I. Shainberg
Download or read book Soil Salinity under Irrigation written by I. Shainberg and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The importance of irrigation in the world's agriculture is rapidly increasing. Although it is practised on a large scale mainly in arid and semi-arid zones, supplementary irrigation is becoming popular in semi-humid regions as well. The record of irrigation speaks for itself in terms of increased crop production. However, the question remains as to how permanent the achievement may be. Judging from history, it seems that irrigation eventually failed in many regions because the knowledge and technology available to society at the time were incapable of coping with the problems created. Undoubtedly soil salinity is the most prevalent and widespread problem limiting crop productivity in irrigated agriculture. It has, therefore, attracted the attention of the scientific community since the advent of modern agronomic research. Through the past six to seven decades a considerable body of information has been accumulated, which has promoted the understanding of the principles involved and helped to develop the technology for coping with the problems. Our present knowledge, if judiciously applied, is adequate for coping with many of the salinity problems resulting from mismanagement of irrigation and drainage. But for this knowledge to be used, it has to be generally known and understood and be re-examined from time to time.

Book Synopsis More Crop Per Drop by : Meredith Giordano
Download or read book More Crop Per Drop written by Meredith Giordano and published by IWA Publishing. This book was released on 2007-01-01 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is an analytical summary and a critical synthesis of research at the International Water Management Institute over the past decade under its evolving research paradigm known popularly as 'more crop per drop'. The research synthesized here covers the full range of issues falling in the larger canvas of water-food-health-environment interface. Besides its immediate role in sharing knowledge with the research, donor, and policy communities, this volume also has a larger purpose of promoting a new way of looking at the water issues within the broader development context of food, livelihood, health and environmental challenges. More crop per drop: Revisiting a research paradigm contrasts the acquired wisdom and fresh thinking on some of the most challenging water issues of our times. It describes new tools, approaches, and methodologies and also illustrates them with practical application both from a global perspective and within the local and regional contexts of Asia and Africa. Since this volume brings together all major research works of IWMI, including an almost exhaustive list of citations, in one single set of pages, it is very valuable not only as a reference material for researchers and students but also as a policy tool for decision-makers and development agencies.

Book Synopsis Environmental Consequences of the Chernobyl Accident and Their Remediation by : International Atomic Energy Agency
Download or read book Environmental Consequences of the Chernobyl Accident and Their Remediation written by International Atomic Energy Agency and published by IAEA. This book was released on 2006 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion on 26 April 1986 at the Chernobyl nuclear power plant and the consequent reactor fire resulted in an unprecedented release of radioactive material from a nuclear reactor and adverse consequences for the public and the environment. Although the accident occurred nearly two decades ago, controversy still surrounds the real impact of the disaster. Therefore the IAEA, in cooperation with other UN bodies, the World Bank, as well as the competent authorities of Belarus, the Russian Federation and Ukraine, established the Chernobyl Forum in 2003. The mission of the Forum was to generate 'authoritative consensual statements' on the environmental consequences and health effects attributable to radiation exposure arising from the accident as well as to provide advice on environmental remediation and special health care programmes, and to suggest areas in which further research is required. This report presents the findings and recommendations of the Chernobyl Forum concerning the environmental effects of the Chernobyl accident.
Book Synopsis Irrigation Water Pricing by : François Molle
Download or read book Irrigation Water Pricing written by François Molle and published by CABI. This book was released on 2007-01-01 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much hope has been vested in pricing as a means of helping to regulate and rationalize water management, notably in the irrigation sector. The pricing of water has often been applied universally, using general and ideological policies, and not considering regional environmental and economic differences. Almost 15 years after the emphasis laid at the Dublin and Rio conferences on treating water as an economic good, a comprehensive review of how such policies have helped manage water resources an irrigation use is necessary. The case-studies presented here offer a reassessment of current policies by evaluating their objectives and constraints and often demonstrating their failure by not considering the regional context. They will therefore contribute to avoiding costly and misplaced reforms and help design water policies that are based on a deeper understanding of the factors which eventually dictate their effectiveness.

Book Synopsis Coping with Water Scarcity by : Luis Santos Pereira
Download or read book Coping with Water Scarcity written by Luis Santos Pereira and published by Springer Science & Business Media. This book was released on 2009-03-22 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main problems confronting the world of the 21st Century is a shortage of water. There is already severe scarcity in many regions of the world, causing tremendous problems for local populations and indeed entire societies. There is insufficient water available for the production of food to alleviate poverty and starvation; the lack of water hampers industrial, urban and tourism development, forcing restrictions on other sectors, especially agriculture; health problems arise as the deterioration of ground and surface waters favours water-borne diseases, which flourish in the absence of decent water distribution and sewerage systems. Water conflicts still arise in areas under stress, while water for nature has become a vanishing priority in such zones. This book is a guide to the establishment of regional and/or local guidelines for developing and implementing new ideas for coping with water scarcity. The basic premise underlying the book is that water scarcity will persist, so personal, human and society-wide skills will be needed to cope with it while living in harmony with the necessary environmental constraints. The book provides basic information to assist decision makers, water managers, engineers, agronomists, social scientists and other professions (and their students) in formulating coherent, hopefully harmonious and consolidated views on the issue. Guidelines are also given for introducing the general public to the concept of water scarcity and how to deal with it.
