Available in PDF, EPUB and Kindle. Book excerpt: Irrigated agriculture is the most significant user of fresh water in the world and, due to the large area occupied, is one of the major pollution sources for the water resources. This book comprises 12 chapters that cover different issues and problematics of irrigated agriculture: from water use in different irrigated systems to pollution generated by irrigated agriculture. Moreover, the book also includes chapters that deal with new possibilities of improving irrigation techniques through the reuse of drainage water and wastewater, helping to reduce freshwater extractions. A wide range of issues is herein presented, related to the evaluation of irrigated agriculture impacts and management practices to reduce these impacts on the environment.
Download or read book Handbook of Irrigation Hydrology and Management written by Saeid Eslamian and published by CRC Press. This book was released on 2023-05-31 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever-increasing population growth has caused a proportional increased demand for water, and existing water sources are depleting day by day. Moreover, with the impact of climate change, the rates of rainfall in many regions have experienced a higher degree of variability. In many cities, government utilities have been struggling to maintain sufficient water for the residents and other users. The Handbook of Irrigation Hydrology and Management: Irrigation Methods examines and analyzes irrigated ecosystems in which water storage, applications, or drainage volumes are artificially controlled in the landscape and the spatial domain of processes varies from micrometers to tens of kilometers, while the temporal domain spans from seconds to centuries. The continuum science of irrigation hydrology includes the surface, subsurface (unsaturated and groundwater systems), atmospheric, and plant subsystems. Further, the book addresses the best practices for various types of irrigation methods including pressure, smart, surface, and subsurface, and presents solutions for water scarcity and soil salinity in irrigation. Features: Offers water-saving strategies to increase the judicious use of scarce water resources Presents strategies to maximize agricultural yield per unit of water used for different regions Compares irrigation methods to offset changing weather patterns and impacts of climate change
Download or read book Field guide to improve crop water productivity in small scale agriculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-04-01 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: By 2050, the world’s population will reach 9.1 billion, which requires an increase of food production by 70 percent compared to 2005 (FAO,2018). Nearly all the increase will occur in developing countries, where agriculture plays a major role to provide employment, income and to improve food security. One of the major challenges of increasing food supply is the limited water resources. Agriculture, as the driver of freshwater exploitation has, therefore, to be transformed into more resource efficient production (FAO, 2003). The world’s limited freshwater resources are potentially threatened by the expansion of agriculture. Increasing the potential output per amount of water used is an appropriate practice to improve production efficiency while protecting water resources. Therefore, increasing the productivity of agricultural water use in a sustainable manner is essential to ultimately sustain the social and economic conditions of livelihoods. Crop water productivity has grown into one of the major approaches to cope with water scarcity and advance crop-water relation. The number of conceptual frameworks and implications is ample, but there is always a growing need to review the step-by-step approach beyond. In this Field guide, practical pathways are presented to provide a comprehensive approach for assessing and improving crop water productivity in small-scale agriculture. The Field guide draws lessons learned in three countries (Burkina Faso, Morocco and Uganda) within the framework of FAO project “Strengthening Agricultural Water Efficiency and Productivity at the African and Global Level” funded by Swiss Agency for Development and Cooperation (SDC).
Download or read book Water Use in Crop Production written by M.b. Kirkham and published by CRC Press. This book was released on 2024-11-01 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Make the best use of available water for your crops!Water Use in Crop Production explores innovative methods that determine how much water certain crops need, in certain climates, in order to ensure adequate plant growth and help eliminate water waste. Through this informative book, agronomists, growers, researchers, and graduate students will find methods and techniques for effective water management that will save money and conserve water. Water Use in Crop Production will enable you enhance crop quality and quantity and save one of the earth's most important resource.Comprehensive and thorough, this essential book combines two vital needs, food and water, and examines what must be done in order to keep up with the ever-growing human population. Explaining conservation techniques used in Argentina, Australia, Israel, Morocco, New Zealand, the Philippines, Spain, and the United States, Water Use in Crop Production will help you achieve this goal as it discusses water management measures including: avoiding excessive deep percolation reducing runoff lessening water evaporation through methods such as reducing the capillary water flow to the surface of the soil determining the rates at which water is demanded and can be supplied in a specific area to create a plan for limiting water loss studying the root structure of plants to calculate how much water they need using deficit irrigation to help plants save water for future use evaluating citrus water use through the Penman-Monteith model Containing charts, tables, and examples of the concepts it discusses, this book is the culmination of the latest studies on water storage. Water Use in Crop Production provides you with reliable strategies and methods that will help you lessen water expenditures and improve the vitality of crops anywhere in the world.

This book was released on 2015-10-15 with total page 964 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the still very valuable Biblioteca histórica de la filología by Cipriano Muñoz y Manzano, conde de la Viñaza (Madrid, 1893), our knowledge of the history of the study of the Spanish language has grown considerably, and most manuscript and secondary sources had never been tapped before Hans-Josef Niederehe of the University of Trier courageously undertook the task to bring together any available bibliographical information together with much more recent research findings, scattered in libraries, journals and other places. The resulting Bibliografía cronológica de la lingüística, la gramática y la lexicografía del español: Desde los principios hasta el año 1600 (BICRES) began appearing in 1994. BICRES I covered the period from the early beginnings to 1600), followed by BICRES II (1601–1700), BICRES III (1701–1800), and together with Miguel Ángel Esparza Torres of Madrid there followed BICRES IV (1801 to 1860). Now, the fifth volume, has become available, covering the years from 1861 to 1899. Access to the bibliographical information of altogether 5,272 titles is facilitated by several detailed indexes, such as a short title index, a listing of printers, publishers and places of production, and an author index. More than twenty years of research in the major libraries of Spain and other European countries have gone into this unique work — relative sources of the Americas have also been covered — making it exhaustive source for any serious scholar of any possible aspect of the Spanish language.
