Download or read book Water Requirements for Irrigation and the Environment written by Marinus G. Bos and published by Springer Science & Business Media. This book was released on 2008-11-23 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture produces about 40% of all food and fibre on about 16% of all cropped land. As such, irrigated agriculture is a productive user of resources; both in terms of yield per cropped area and in yield per volume of water consumed. Many irrigation projects, however, use (divert or withdraw) much more water than consumed by the crop. The non-consumed fraction of the water may cause a variety of undesirable effects ranging from water-logging and salinity within the irrigated area to downstram water pollution. This book discusses all components of the water balance of an irrigated area; evapotranspiration (Ch.2), effective precipitation (Ch.3) and capillary rise from the groundwater table (Ch.4). Chapter 5 then combines all components into a water management strategy that balances actual evapotranspiration (and thus crop yield) with the groundwater balance of the irrigated area (for a substainable environment). Chapter 6 presents CRIWAR 3.0, a simulation program that combines all water balance components into a single simulation procedure. The chapter describes the use of the CRIWAR software for developing water requirement tables and other useful information based on the selected water management strategy. This version greatly expands upon the capabilities of previously published programs.

This book was released on 2010-09-08 with total page 578 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is one of the few industries that has been creating resources conti- ously from nature. Sustainability of this industry is a crucial issue at now-a-days. Agricultural technologies are important to feed the growing world population. Agricultural engineering has been applying scienti?c principles for the optimal use of natural resources in agricultural production for the bene?t of humankind. The role of agricultural engineering is increasing in the coming days at the forthcoming challenges of producing more food with less water coupled with climate uncertainty. I am happy to know that a book entitled "Fundamentals of Irrigation and On-farm Water Management", written by Engr. Dr. M. H. Ali, is going to be p- lished by Springer. The book is designed to cover the major ?elds of agricultural and environmental engineering such as weather, plant, soil, water, and basics of on-farm water management. The book will be quite useful for the students of agricultural engineering.

Utilization of the recent literature in the area and citation of relevant journals / reports have added a special value to this book. Considering the topics covered, engineers, scientists, practitioners, and educators will ?nd this book as a valuable resource.
Download or read book Irrigation Systems written by Adrian Laycock and published by CABI. This book was released on 2011 with total page 315 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all the confrontations man has engineered with nature, irrigation systems have had the most widespread and far-reaching impact on the natural environment. Over a quarter of a billion hectares of the planet are irrigated and entire countries depend on irrigation for their survival and existence. Considering the importance of irrigation schemes, it is unfortunate that until recently the technology and principles of design applied to their construction has hardly changed in 4,000 years. Modern thinking on irrigation engineering has benefited from a cross-fertilization of ideas from many other fields including social sciences, control theory, political economics and agriculture. However, these influences have been largely ignored by irrigation engineers. Drawing on almost 40 years of experience of irrigation in the developing world, Laycock introduces new ideas on the design of irrigation systems and combines important issues from the disciplines of social conflict, management, and political thinking.

Download or read book Charging for Irrigation Water written by C. J. Perry and published by IWMI. This book was released on 2001 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: nadequate funding for maintenance of irrigation works and emerging shortages of water are prevalent. The use of water charges to generate resources for maintenance and to reduce demand is widely advocated. Examples from other utilities, and from the domestic/industrial sectors of water supply suggest the approach could be effective. In developing countries, the facilities required for measured and controlled delivery of irrigation are rarely in place, and would require a massive investment in physical, legal and administrative infrastructure. To be effective in curtailing demand, the marginal price of water must be significant. The price levels required to cover operation and maintenance (O&M) costs are too low to have a substantial impact on demand, much less to actually bring supply and demand into balance. On the other hand, the prices required to control demand are unlikely to be within the politically feasible range. Furthermore, water supplied is a proper measure of service in domestic and industrial uses. But in irrigation, and especially as the water resource itself becomes constrained, water consumption is the appropriate unit for water accounting. This is exceptionally difficult to measure. An alternative approach to cope with shortage would focus on assigning volumes to specific uses–effectively rationing water where demand exceeds supply. This approach has a number of potential benefits including simplicity, transparency, and the potential to tailor allocations specifically to hydrological situations, particularly where salinity is a problem. Data from Iran are presented to support these contentions.

Download or read book Water and Power in Highland Peru written by Paul H. Gelles and published by Rutgers University Press. This book was released on 2000 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cabanaconde, a town of 5,000 people, is located in the arid Andean highlands. It is dominated by the foreboding Hualca Hualca mountain peak that is the source of this town's much-needed water. How the villagers obtain this water, Paul Gelles writes, is not a simple process: the politics of irrigation in this area reflect a struggle for control of vital resources, deeply rooted in the clash between local, ritualized models of water distribution and the secular model put forth by the Peruvian state. Water and Power in Highland Peru provides an insightful case study on the intense conflicts over water rights, and a framework for studying ethnic conflict and the effects of "development," not only in Peru, but in other areas as well. Most of the inhabitants of Cabanaconde do not identify themselves with the dominant Spanish-speaking culture found in Peru. And the Peruvian state, grounded in a racist, post-Colonial ethos, challenges the village's long-standing, non-Western framework for organizing water management. Gelles demonstrates that Andean culture is dynamic and adaptive, and it is a powerful source of ethnic identity, even for those who leave the village to live elsewhere. Indigenous rituals developed in this part of the world, he states, have become powerful tools of resistance against interference by local elites and the present-day Peruvian state. Most importantly, the micropolitics of Cabanaconde provide a window into a struggle that is taking place around the world.

Available in PDF, EPUB and Kindle. Book excerpt: This report contains a collection of papers from a workshopâ€"Strengthening Science-Based Decision-Making for Sustainable Management of Scarce Water Resources for Agricultural Production, held in Tunisia. Participants, including scientists, decision makers, representatives of non-profit organizations, and a farmer, came from the United States and several countries in North Africa and the Middle East. The papers examined constraints to agricultural production as it relates to water scarcity; focusing on 1) the state of the science regarding water management for agricultural purposes in the Middle East and North Africa 2) how science can be applied to better manage existing water supplies to optimize the domestic production of food and fiber. The cross-cutting themes of the workshop were the elements or principles of science-based decision making, the role of the scientific community in ensuring that science is an integral part of the decision making process, and ways to improve communications between scientists and decision makers.
