“…Table 3 Total area cultivated with rice in la Saison, and the averages (l) of actual evapotranspiration, estimated fresh rice yields and water productivity for the Office du Niger as a whole, the five administrative zones and for the casiers located in the Niono zone Rice area (ha) Actual evapotranspiration (mm) Estimated rice yield (ton ha The standard deviation (r) and the coefficient of variation (c v ) for each parameter are presented also Irrig Sci (2010) 28:371-385 379 The c v of water consumption in the Office du Niger equals 0.092 (Table 3) which implies that the water consumption is spatially heterogeneous during la Saison. As mentioned before, water is abundantly available during this season, and crop growth appears not to be hampered by water shortages (Vandersypen et al 2006(Vandersypen et al , 2009. The values for c v found in the Office du Niger are similar to those measured in the Nile Delta in Egypt, which equalled 0.10 (Bastiaanssen 1997).…”

“…One explanation for the lower yields could therefore be a less homogeneous water distribution in these zones. Measurements of water deliveries to tertiary units between June and October 2004 varied from 8 to 30 m 3 ha -1 (Vandersypen et al 2006), which confirms that a large difference in supply exists.…”

“…Measurements of water balances in rice fields in the Office du Niger in the 1980s show even higher evapotranspiration rates of 720-910 mm in la Saison (Hendrickx et al 1986). Water is abundant during la Saison, and fields are continuously over-supplied (Vandersypen et al 2006), which is an explanation for the high water consumption.…”

“…The network consists of primary (distributeur), secondary (partiteur) and tertiary (arroseur) canals. Farmers conduct irrigation and drainage of individual rice fields by, respectively, extracting from or discharging water to the field canals which are connected to the tertiary canals and drains (Vandersypen et al 2006). …”

The irrigation performance of the Office du Niger in Mali, a large-scale rice-based irrigation scheme, was analysed with the use of remote sensing technology. The major advantage of remote sensing derived data over field measured data is that it provides system-wide, spatially distributed and objective information. Four irrigation performance indicators, entirely based on remote sensing, were applied at different organisational levels of the system. The surface energy balance algorithm for land model was applied to high-resolution Landsat images to calculate rice production and water consumption spatially. These maps were used to analyse the productivity of water, the uniformity of water consumption and head-/tail-enders issues at the level of the system, the five administrative zones and smaller management units (casiers). The sustainability of the system was assessed using a long-term time series of the normalised difference vegetation index. The results were discussed and interpreted with the irrigation managers of the Office du Niger. The analysis provided new insights in the performance of the system such as existing head-tail patterns in water consumption and rice yields.

“…They highlighted that factors causing poor irrigation performance derived in part from management, and in part from physical structure. Vandersypen et al [14] evaluated the irrigation performance of the Office du Niger (Mali) in 1995 and 2004 using these four indicators. They found that the physical rehabilitation of the irrigation network made the irrigation delivery service excellent.…”

Irrigation performance assessment is an important step in ensuring sustainable agricultural development and improving the capacity of irrigation water management. In this paper, we examined irrigation water management in the Jiamakou Irrigation Scheme in the province of Shanxi (China) using four typical indicators, namely adequacy, efficiency, dependability, and equity. These indicators were calculated both globally and by grouping the data according to different irrigation processes (water allocation and water delivery). Results show that water was poorly allocated, and crop water requirements calculated through the FAO56 Penman-Monteith method was not met timely by scheduled water. They indicate that the overall performance of the scheme was relatively poor, owing to dismal water allocation. Nevertheless, water delivery performance was good, indicating that the scheme was able to deliver adequate and dependable water in an equitable and efficient manner. Our findings suggest that farmers should be trained in allocating irrigation water. The study provides insights into the current behavior of the irrigation scheme and may be used as a base for improvement of irrigation performance.

The objective of this study was to assess the water delivery performance of the Som Kamla Amba irrigation scheme located in the Dungarpur district of Rajasthan using adequacy, equity and dependability indicators. Three minors each at the head, mid and tail sections of main canals (Right and Left Main Canal) and branch canals (Aspur Branch Canal and Baroda Branch Canal) were selected. The ratio of water delivered (obtained from discharge measured at outlets) and water required (calculated from CROPWAT software) was determined for major rabi crops (wheat, barley, gram and mustard) grown in the command area in 2011–2012. Results had shown good (1.00 to 0.93), fair (0.84 to 0.80) and poor (0.42 to 0.18) adequacy at the head, mid and tail sections of each canal respectively. Also there is poor equity in water delivery as its value varied from 0.35 to 0.92. Dependability was found to be good at head, fair at mid and poor at tail sections. © 2018 John Wiley & Sons, Ltd.
