Book Description
Rapid Industrialisation Coupled With Population Explosion Has Resulted In Greater Urbanisation. Because Of These, The Water That Was Available For Agriculture Is Now Being Shared By Various Sectors. This Has Resulted In A Gradual Decline In Per Capita Land And Water Availability. At The Same Time The Need To Increase The Food Production To Feed The Increasing Population Is Being Increasingly Felt. Mismanagement Of Available Water Has Added One More Dimension To This Problem Resulting In Development Of Problem Soils, Thus Causing Reduction In The Production Per Unit Quantity Of Water. Hence It Has Become Absolutely Necessary To Use The Available Water Resources In Such A Manner As To Get The Maximum Returns Per Unit Quantity Of Water. At Present No Book Covers The Multifaceted Nature Of This Problem. Hence In This Book All Aspects Like Methods Of Irrigation, Measurement Of Water, Quality Of Waters, Water Requirements Of Crops, Scheduling Of Irrigation, Water Budgeting, Irrigation Efficiency, Drainage, Recycling, Agronomy, Soil Science, Crop Physiological Aspects Of Irrigation System, Etc. Have Been Covered. A Separate Section Of Constraints And Weakness In The Current Water Management Practices Is Also Included In This Book.This Book Will Be Of Great Help To The Administrators Dealing With Water Management, Water Technologists, Scholars And Farmers Who Are Taking Steps To Maximise The Benefits Of The Available Water Resources On The Scientific Basis To Get The Higher Productivity Of Water.

Book Description
Essay from the year 2016 in the subject Geography / Earth Science - Physical Geography, Geomorphology, Environmental Studies, language: English, abstract: Taking into consideration the alarming fact of a water crisis, there is a need to efficient water management to conserve the precious input. This text explains the different strategies for efficient management of water for agricultural use involving: conservation of water, integrated water use and optimal allocation of water. Water is more crucial to Indian agriculture than is commonly perceived. India's water resources are under considerable stress as the race between food production and population growth surges relentlessly. With 4 per cent of the world's water resources and 18 per cent of its population, the country will be hard pressed to meet the water requirements of the various growing sectors. Continual population growth and the predicted impacts of climate change, including shifts in precipitation and glacier melt, makes the water challenge greater. For better use of water in agriculture in water-limited environments, efforts are needed from different research disciplines: agronomists, plant breeders, plant physiologists, plant biotechnologists, water engineers and others, to develop new approaches in water conservation. For example, is it possible to develop crops that require less water and maintain high yield productivity? Among different approaches water productivity or water use efficiency (WUE) is an efficient approach.

Book Description
For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

Book Description
Managing water resources is one of the most pressing challenges of our times - fundamental to how we feed 2 billion more people in coming decades, eliminate poverty, and reverse ecosystem degradation. This Comprehensive Assessment of Water Management in Agriculture, involving more than 700 leading specialists, evaluates current thinking on water and its interplay with agriculture to help chart the way forward. It offers actions for water management and water policy - to ensure more equitable and effective use. This assessment describes key water-food-environment trends that influence our lives today and uses scenarios to explore the consequences of a range of potential investments. It aims to inform investors and policymakers about water and food choices in light of such crucial influences as poverty, ecosystems, governance, and productivity. It covers rainfed agriculture, irrigation, groundwater, marginal-quality water, fisheries, livestock, rice, land, and river basins. Ample tables, graphs, and references make this an invaluable work for practitioners, academics, researchers, and policymakers in water management, agriculture, conservation, and development. Published with IWMI.

Book Description
First title in a major new seriesAddresses improving water productivity to relieve problems of scarcity and competition to provide for food and environmental securityDraws from scientists having a multitude of disciplines to approach this important problemIn a large number of developing countries, policy makers and researchers are increasingly aware of the conflicting demands on water, and look at agriculture to be more effective in its use of water. Focusing on both irrigated and rain-fed agriculture, this book gives a state of the art review of the limits and opportunities for improving water productivity in crop production. It demonstrates how efficiency of water use can be enhanced to maximize yields. The book represents the first in a new series of volumes resulting from the Comprehensive Assessment of Water Management in Agriculture, a research program conducted by the CGIAR's Future Harvest Centres, the Food and Agriculture Organization of the United Nations and partners worldwide. It will be of significant interest to those working in areas of soil and crop science, water management, irrigation, and development studies.

Book Description
This book is an outcome from the International Expo 'Water and Sustainable Development' held in Zaragoza (Spain) in 2008. Support from the Spanish Ministry of Environment, Caja Rioja, Government of Aragon, and the World Bank is acknowledged. 'Few resources will play a more important role in shaping our economic future, or face more daunting challenges, than water. This internationally acclaimed team of experts has produced a first-rate volume that is full of intriguing, practical ideas for meeting those challenges in a rich variety of institutional settings.' Tom Tietenberg, Mitchell Family Professor of Economics, Emeritus, Colby College, USA 'This volume brings together two critical but interrelated dimensions of water challenge, i.e. water pollution, particularly from non-point sources, and water conservation. The editors are well known experts on the subject as are the contributors.' R. Maria Saleth, International Water Management Institute, Sri Lanka and Associate Editor, Water Policy 'The profound contribution of this volume is that it brings together various economic concepts and policy dilemmas regarding water shortages, non-point source pollution, efficiency of water use and irrigation technology. Recommended reading for anyone working in the area of water management.' Henk Folmer, University of Groningen and Wageningen University, The Netherlands As countries face deteriorating water and environmental quality as well as water shortages, pollution control and the efficiency of water use become of paramount importance. Agriculture is one of the main non-point polluters of water bodies and irrigation for agriculture is one of the main consumers of water. While it is very hard to regulate pollution from agriculture, attempts have been made via economic and command and control instruments, and also through investments in technologies and ecosystems recovery. Coping with non-point pollution takes the form of both policy intervention and technology development. Likewise it is recognized that irrigation efficiency varies across countries, influenced by both technology and supporting adoption policies. Countries that lead in irrigation technology and supporting policies have certain traits in common. They face very high scarcity and are pushed to find innovative solutions, both technical and policy related. The recent multibillion investments in irrigation technologies in Spain, and similar proposals in Australia, for example, highlight the potential of irrigation technologies to cope with scarcity and water quality degradation. This book reviews all of the above issues, presents experiences in selected countries, and assesses the degree of success of alternative policies for coping with non-point water pollution and improving irrigation efficiency.
