We aim to develop and improve a set of specific technologies and identify synergistic institutional innovations to improve water use and allocation efficiency in agriculture; this requires a systems approach to capture the important interdependencies within and between biophysical and social-economic systems. Increasing food demand and declining water resources are challenges for food security (Kreye et al., 2009). At present most of the water used to grow crops is derived from rainfed soil moisture, 70%. irrigation scheme managers and water users in agriculture." The system is applied for generating water use efficiency reports, water transfers between users, calculation of scheme water balances, dam information, calculation of water releases for distribution, billing systems and a bulk SMS system, amongst others. The results however suggests more ambitious plan to boost irrigation efficiency for summer rice in order to overweight any potential shrinkages in its output and exports. Ensuring accountability and transparency and creating awareness are important to meet time-bound targets pertaining to sustainable water use in agriculture. 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. SOM from 1 %to 2 % will increase nitrogen-use efficiency from 19.1 to 36.6 kg of wheat per kg of applied nitrogen under Portugal's condition (Carvalho & Lourenço, 2014). Water scarcity and competition in the Vietnamese Mekong Delta becomes a great matter of concern under the contexts of climate change and tributary dam construction in upstream countries. While irrigation can increase yields of most crops by 100 to 400 percent, water resources remain limited. These values are higher than average water use efficiency observed for the whole Mediterranean region [17]. These urgent conditions mean an emphasis on efficiency: Growers have to use fresh approaches to derive a bigger harvest from the same plots while reducing their overall water use. Efficient transport of irrigation water 4. The long term vision of the . National Water Mission is to increase water use efficiency in all sectors of water use by 20% by the year 2017 i.e. Efficient application of irrigation water 3. At present most of the water used to grow crops is derived from rainfed soil moisture, To Combat Scarcity, Increase Water-Use Efficiency in Agriculture. Efficiency improvements that reduce total water demands can reduce these adverse fish and wildlife impacts. In irrigated agriculture, WUE is broader in scope than most agronomic applications and must be considered on a watershed, basin, irrigation district, or catchment scale. 2.
