Book excerpt: Modern Land Drainage 2nd edition is a fully revised and updated edition of the 2004 edition. Modern Land Drainage describes traditional drainage formulas (Hooghoudt, Kirkham, Donnan, Ernst, Glover-Dumm) for rainfed agriculture in the humid temperature zone. Significant parts are devoted to drainage for salinity control of irrigated land in (semi-) arid zones, and to drainage of rice land in the humid tropics. Institutional, management and maintenance aspects are extensively covered, as well as the mitigation of adverse impacts of drainage interventions on the environment. The latest computer applications for drainage design in the context of integrated water management are described (DRAINMOD, HEC, SWAP, etc.). Field surveys are executed by governments, with the aid of consultants, but rarely are the end stakeholders (i.e., farmers and general public) involved from inception to planning to execution of a drainage system. Yet, during the Operation, Management and Maintenance (OMM) phase of a water management system, they are expected to takeover, run, bear and be responsible for the costs of OMM. The book describes successful methodologies and processes to be followed for engagement of stakeholders at all levels, from government to farm, from minister to farmer, and, from beginning to end. The book covers all aspects needed for sustainable drainage. The latest survey methodologies with satellites and drones are suggested to assess cause and effect. Waterlogging and salinity are the effect of something caused most likely upstream of the drainage problem location. Hence treating the cause may be more cost-effective. Triple Bottom Line (social, environmental and financial considerations) and the water-food-energy nexus are an integral part of the drainage design process. Controlled drainage, i.e. the balance of removal and conservation of drainage water and minimising solute transport as low as reasonably achievable (ALARA principle) is extensively described. This work is intended for use both as a university level textbook and as a professional handbook; it is of particular value to professionals engaged in drainage development in the context of integrated water resources and river basin management, civil and agricultural engineers, government officials, university students and libraries.

Download or read book Land Drainage and Irrigation written by Salvatore Ciriacono and published by Routledge. This book was released on 2017-05-15 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Man’s control over the elements of land and water for the purposes of agriculture was fundamental to the development of civilisations in the past, and remains so today. This volume deals with the processes of irrigation, and land drainage and reclamation, and illustrates the variety of technological and engineering solutions in a wide chronological and geographical perspective. The sophistication of many pre-modern systems is clear, as is the impact of modern technologies. Important points that emerge are that there was no steady or linear progression in techniques across time - instances of the transfer of ideas are balanced by cases of independent development - and that the correlations between irrigation systems and social structures demand more complex explanations than often proposed.

This book was released on 2007 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this paper is to facilitate the planning and design of land drainage systems for sound land and water management for engineers and other professionals. It considers the integration of technical, socio-economic and environmental factors and the need for system users' participation in the planning, design, operation and maintenance processes. The text provides guidelines for the appropriate identification of drainage problems, for the planning and design of field drainage systems (surface and subsurface) and the main drainage and disposal systems. The annexes provide more detailed information with technical background, appropriate equations, some cross-references for finding appropriate methodologies, and computer programs for calculation of extreme values, of permeability and some land drainage system parameters. --Publisher's description.

Download or read book Building on Water written by Salvatore Ciriacono and published by Berghahn Books. This book was released on 2006-05 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fundamental natural resource, water and its use not only reflect "modes of production" but also that complex interplay between resources and their exploitation (and domination) by various social agents, who in their turn are inevitably influenced by the abundance or rarity of water supplies. Focusing on scientific, social and economic issues from the 16th to the 19th century, the author, one of Italy's leading historians in this field, looks at the innumerable conflicts that arose over water resources and the environmental impact of projects intended to control them. Venice and Holland are undoubtedly the two most fascinating cases of societies "built on water," with the conquest of vast expanses of marshland - either inland or on the coast (the Dutch polders or the Venetian lagoon) – not only stimulating agricultural production, but also nurturing a deeply-felt relationship between the local populations and the element of water itself. The author rounds off his study by looking at the influence the hydraulic technology developed in Holland would have on many European countries (France, England and Germany in particular) and at questions raised by contemporaries about the environmental impact of agricultural progress and its effects upon the social-economic equilibria within the communities concerned.
Download or read book Research Developments in Saline Agriculture written by Jagdish Chander Dagar and published by Springer. This book was released on 2019-06-21 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and water salinity is a major challenge for the agricultural community and policy makers in terms of meeting the burgeoning population’s demand for food and other agricultural commodities. In coastal regions, climate change and sea level rise will aggravate the problem with more and more areas becoming saline due to intrusion of sea water. As such there is a pressing need for modern tools and innovative techniques for the identification of salty soils and poor-quality waters, crop production, soil reclamation and lowering the water table in waterlogged areas. Tackling next-generation problems such as contamination of soil and underground water due to fluoride and arsenic, as well as developing multi-stress tolerant crops is also a high priority. Further, techniques for domesticating halophytes, mangrove-based aquacultures, using seaweed cultures as agricultural crops and integrated farming systems need to be perfected. This book addresses all these aspects in detail, highlighting the diverse solutions to tackle the complex problem of salinity and waterlogging and safer management of poor-quality waters. With chapters written by leading experts, it is a valuable resource for researchers planning future investigations, policy makers, farmers and other stakeholders, and for students wanting insights into vital issues of environment.
Download or read book American Agriculture Water Resources and Climate Change written by Gary D. Libecap and published by University of Chicago Press. This book was released on 2024-01-10 with total page 403 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collection of the most advanced and authoritative agricultural-economic research in the face of increasing water scarcity. Agriculture has been critical in the development of the American economy. Except in parts of the western United States, water access has not been a critical constraint on agricultural productivity, but with climate change, this may no longer be the case. This volume highlights new research on the interconnections between American agriculture, water resources, and climate change. It examines climatic and geologic factors that affect the agricultural sector and highlights historical and contemporary farmer responses to varying conditions and water availability. It identifies the potential effects of climate change on water supplies, access, agricultural practices, and profitability, and analyzes technological, agronomic, management, and institutional adjustments. Adaptations such as new crops, production practices, irrigation technologies, water conveyance infrastructure, fertilizer application, and increased use of groundwater can generate both social benefits and social costs, which may be internalized with various institutional innovations. Drawing on both historical and present experiences, this volume provides valuable insights into the economics of water supply in American agriculture as climate change unfolds.
