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 1/5(1). water use efficiency or more importantly the water productivity. This chapter explains in detail the concept and measurement of ‘water-use efficiency’ and ‘water productivity’ as applied at plant, field, farm, region/sub-basin, basin and national level through . Water scarcity is worsened by climate change. Water savings can be reached by improving irrigation efficiency both on farm and on water supply. To do that, the choice of the best irrigation technology is not always straightforward, because farmers need to renew and implement farm infrastructures for irrigation. This study compares three irrigation systems, one drip irrigation and two sprinkler Cited by: 3. The book “Fundamentals of Irrigation and On-farm Water Management” (Volume 1) is a true textbook for the undergraduate students in Bio-Science Engineering, Agricultural Engineering, Water Resource Engineering, Civil & Environmental Engineering, Biological Systems Engineering, Environmental Science, Biological Sciences and Agricultural Sciences.

Agriculture is coming under more and more pressure to justify its use of the world's freshwater resources and to improve its productive and environmental performance. The allocations of raw water to agriculture (and the allocations within the agriculture sector) all need to be negotiated in a transparent way. This report reviews the large set of literature on the subject and makes the case for. lowest-valued water use, efforts are increasingly undertaken to encourage agricultural water conservation with the aim of transferring some water to higher-valued uses and thus improving the economic efficiency of the allocation of scarce water resources. Since water losses are typically large in irrigated agriculture, adopting improved on-farm.   Agriculture is a major user of ground and surface water in the United States, accounting for approximately 80 percent of the Nation's consumptive water use and over 90 percent in many Western States. Efficient irrigation systems and water management practices can help maintain farm profitability in an era of increasingly limited and more costly water supplies. In 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 give a state of the art review of the limits and opportunities for improving water.

2. Water is essential for every form of life, for all aspects of socio-economic development, and for the maintenance of healthy ecosystems. While there are sufficient freshwater resources at the global level to enable continued agricultural and industrial development, the long-term sustainable use of water. Downloadable! Addressing water use efficiency in the Middle East is challenging due to the geopolitical complexity, climatic conditions and a variety of managerial issues. Groundwater is the dominant water resource for Palestinians, while aquifers are shared with their neighbours. We assessed in this study the efficiency of the agricultural water use in Jericho, which we defined as the Water.   However, the impact on farm economics will likely be the strongest incentive to adopt cover crops. These impacts can include farm profits, cash crop yields or both. This paper provides a review of cover-crop adoption, production, risk and policy considerations from an economic perspective. The specific objectives of this paper are to assess the economic and environmental impacts of different water-harvesting techniques in Jordan's Badia region. Cost benefit analysis (CBA) was used.
