Reservoirs are principal water resources that supply irrigation water to paddy fields and play an important role in water resources management in South Korea. For optimal irrigation reservoir operation and management, it is necessary to determine the duration of irrigation water shortages. Management of reservoir operation and irrigation scheduling should take into consideration essential varia...

An analysis of irrigation, agriculture, livelihood and poverty linkages in the districts of Odisha has been carried out. District-wise scenario of irrigation, agriculture, livelihood and poverty has been revealed with the help of different indexes developed. The values of Groundwater Development Index have been found low to very low for 25 districts. Created irrigation potential out of the tota...

Between 1995 and 2003 sugarcane farmers in Bundaberg had access to limited irrigation water. Over this time water allocations were effectively a quarter of the requirements for a fully irrigated crop. In response to this problem irrigation strategies were developed to assist farmers. Field investigations focused on the performance of water winch and furrow irrigation systems, which make up 91% ...

Pasture performance of 924 dairy farms in a major irrigation district of Australia was investigated for their water use and water productivity during the 2015-2016 summer which was the peak irrigation period. Using satellite images from Landsat-8 and Sentinel-2, estimates of crop coefficient (Kc) were determined on the basis of a strong linear relationship between crop evapotranspiration (ETc) ...

Livelihoods of the rural people of Ethiopia depend on agriculture. However, erratic nature of rain and prevalence of drought in the country make agricultural production a challenge. To counter this problem, use of the available water resource for irrigation development is the most promising option. Ketar small scale irrigation scheme is found in Ketar-Genet Peasant association, Tiyo District, A...

Nitrogen (N) pollution induced by irrigated agriculture is a significant environmental problem. The main N inputs and outputs were measured or estimated in the semi-arid La Violada irrigation district (Spain). Data on two periods (1995-98 and 2006-08) were compared and related to observed changes during the decade in cropping patterns and N fertilization and irrigation management. N fertilizati...

Wepropose a price gamemodel of irrigationwater in a coastal irrigation district.Then,we discuss the stability and codimension-two period-doubling (flip) bifurcation.Then, the MATLAB package Cl MatContM is employed to illustrate its numerical bifurcationsbased continuation methods. Lastly, the 0-1 test algorithm is used to compute the median value of correlation coefficient which can indicate wh...

virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...
