    ). The classical concept of irrigation efficiency used by water engineers omitted economic values and looked at the actual evapo-transpiration (ET) against the total water diverted for crop production (Kijne et al., ). Moreover, it does not factor . The economics of agricultural water use and pricing become more complicated when the possibility of groundwater use is considered. Let y t = pumping in year t and x t = the level of the ground1water stock in year t. The level of the stock increases in year t .

    In many developing countries, where agricultural water use is often still subsidised, water pricing policies are developed for allocating water efficiently and achieving sustainability of water systems. However, the impacts of water pricing policies on irrigation water use and on farm production systems is mostly unknown. Irrigation is the application of controlled amounts of water to plants at needed intervals. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall. Irrigation also has other uses in crop production, including frost protection, suppressing weed growth in grain fields and preventing soil.

    called ‘water use efficiency’, a substantially better measure of on-farm water use because it takes into consideration production technology and other inputs. 5 The main contribution of the paper is to explore the relationship between water use efficiency and community-level. Water savings in irrigated agriculture Figure 1. Framework for identifying options to save water in irrigated agriculture.-identified. The range of options or responses to deliver water savings is the focus of this paper. For each measure, there are alternative means of action, each with their own barriers and enablers.

The OFF- AND ON-FARM SAVINGS OF IRRIGATION WATER: Murrumbidgee valley water efficiency feasibility project followed the initial catchment water balance. During this study, targeted data gathering, analysis and modelling were carried out to refine the values for water saving volumes and conduct a cost–benefit analysis within irrigation areas.

The effects of irrigation uniformity are depicted in Figure 2. Maximum yield for a uniform system can be achieved with 70 cm of IW. The second example will be related to saline irrigation water using the production functions depicted in Figures 3 and 4.

Maximum yields of salt tolerant cotton and wheat can be achieved with an irrigation. Also, due to low irrigation efficiency, the irrigation potential created in the world is not being fully used and creates further irrigation demands in the existing system for agricultural production.

Increasing population and climatic changes have further increased irrigation demands and thereby the water stress in the world. This booklet on farm water savings in the Murrumbidgee catchment is derived from two reports— Hydrologic economic ranking of water saving options: on-farm savings of irrigation water and.

In many cases, however, technical efficiency and thus WP may be improved up to a certain degree through simple changes in management.

Agricultural irrigation accounts for a great deal of the water used in the world today, with some areas of the United States using up to 90 percent of available water for farm irrigation water resources become less dependable or available in many areas, the prevention of water loss is an important topic the agricultural community must consider.

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.
