As the competition for the finite water resources on earth increases due to growth in population and affluence, agriculture is faced with intensifying pressure to improve the efficiency of water used for food production.

The causes for the relatively low water use efficiency in agriculture are numerous and complex, including environmental, biological, Cited by: 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 traditional and remote sensing based estimations.

Low water use efficiency of crops Lack of application and popularization of advanced irrigation facilities and techniques for high WUE of crops, the WUE is low compared with developed countries. According to the traditional management, seven times of irrigation in the growing season of winter wheat and summer corn are needed totally, the amount.

is used to define the relationship between crop produced and the amount of water involved in crop production, expressed as crop production per unit volume of water”. Perry et al. () mentioned that, conventionally, water use efficiency was defined in the past as a productivity term “output of crop per unit of water “.

Fruits, vegetables and root crops contain 65 to 95 percent of water and their post-harvest life depends on the rate at which they use up their stored food reserves and their rate of water losses.

When food and water reserves are exhausted the produce dies and decays. CHAPTER 5 Water efficiency in agriculture Globally, agriculture is the largest user of water1 and also uses 85% of the water withdrawn in the MENA region. Additionally, water use in agriculture is often highly inefficient with only a fraction of the water diverted for agriculture effectively used for plant growth, with the rest drained or lost viaFile Size: KB.

A final synthesis will underline the actual gap concerning water use efficiency in the Mediterranean region. This gap will constitute a field of research designated to improve water use efficiency of agriculture in this region.

Methodology for determination of water use efficiency. Two approaches can be considered to determine water use Cited by: Start studying AP enviornmental unit 3. Learn vocabulary, terms, and more with flashcards, games, and other study tools. all of the following are improvements or additions to agriculture that would increase the efficiency of water use and the quality of run off except.

irrigation of annual crops. It has been advocated that in the future, evapo-transpiration and water-use efficiency of crops will alter with climate change (Thomas, ; Mo et al., ).

To ensure that crop systems can adapt to the changing climate, it is important to understand how climate change affects agriculture and water-use efficiency (Mo et al., ). Agricultural Water Conservation, Productivity, and Transfers.

This chapter is a product of the Agricultural Water Conservation, Productivity, and Transfers Workgroup. May May i. potential future opportunities to improve water use efficiency in. On the other hand, mulching increase water use efficiency were reduced the water evaporation from soilsurfaces (Gregory, and Davies et al., Author: Peter J Gregory.

Water Use Efficiency, Scheduling, Water Requirement, Climate Model 1. Introduction Water is the major limiting factor for crop diversification and production. More than 80% of water resources have been exploited for agricultural irrigation. [1] How to cite this paper: Beshir, S. () Review on Estimation of Crop Water Re-File Size: KB.

sectoral approaches for improved water productivity, such as multiple use of water, reducing postharvest losses and basin studies will be discussed briefl y. Increasing Crop Water Productivity Opportunities for improving crop water productivity mainly lie in choosing adapted, water-effi cient crops, reducing unproductive.

2. Water use in agriculture. Some figures at different scales illustrate the amount of water used in agriculture. Globally, some ×10 3 km 3 of water were used in agriculture in ().While significant amounts of water are used in animal production and food processing, water availability limits animal production mostly through the production of fodder crops and Cited by: to increase crop productivity and water use efficiency under availability of water in both dry and irrigated areas.

Ecological aspect of water Water is a vital component of agriculture and a major part of fruits, vegetables and cereal foods consumed by humans, their food grains fed to animals that are used. The evaporation from soil surface was accounted percentage of total evapotranspiration of crop land.

2,3 Several researchers reported that the mulching with agricultural waste such as straw, compost, grass clippings and leaves, etc. had increased the water retention and prevented the soil evaporation. 4,5,6,7 Higher water use efficiency Cited by: 3.

Indian Agriculture % of water consumed for agriculture Lower productivity of most of the major crops Real problem: wastage of water & lack of Demand management, not shortage Wasteful utilisation of water resources diminish crop productivity resulting in lower efficiency.

Water and food safety are two major challenges which the world faces today. Traditional water management focuses on the reduction of water use through improvements in water saving by:   Global crop production will have to double to feed this growing population unless we learn to reduce waste and use water more efficiently.

Given that one liter of water is needed to produce one calorie of food, it will take up to 6, cubic kilometers of additional water annually to feed another billion people. Improving Water and Nutrient Use Efficiency in Food Production Systems provides professionals, students, and policy makers with an in-depth view of various aspects of water and nutrient us in crop production.

The book covers topics related to global economic, political, and social issues related to food production and distribution, describes various strategies and mechanisms that increase Price: $ Step 3. Estimate the water use rate of fruit crops. Table 3 provides information on average daily water use for various fruit crops in southern Ontario as affected by ground cover.

The average daily water use rates are derived from long-term average weekly maximum evapotranspiration at Ridgetown, Simcoe and Windsor using various crop Reviewed: 07/   Water conservation and efficiency can help people curb their water use, and while the two terms might seem like the same thing – as both achieve the same goal of using less water – they approach water savings differently.

Water Conservation. Noted water conservation expert, Amy Vickers, author of the book Water Conservation, defines. the (soil-stored) available water, then applying what has been used + 20% for efficiency loss. Example: a mature standard size (large) fruit tree occupying an area of feet².

A rooting depth of 3 feet, loam soil, and a daily water use (ET) of inches/day in Size: KB. Using science to better conserve water resources. To ensure food security and sustainable water management for agriculture, there is an urgent need to produce more crop per drop of water used in the agricultural sector and hence ensure that water use efficiency is increased without negative impacts on downstream water quantity and quality.
