The rapidly growing population in Uzbekistan has put massive pressure on limited water resources, resulting in frequent water shortages. Irrigation is by far the major water use. Improving irrigation water use through the institutional change of establishing water consumer associations (WCAs) has been identified as a way to increase agricultural production and meet the food demand in the area. However, most WCAs are not fully able to organize collective action or generate sufficient funds to carry out their responsibilities. This study investigated the water-resource-related challenges faced by WCAs and local farmers in Kashkadarya Province in Uzbekistan, using semi-structured expert interviews and focus group discussions. The resulting data were analyzed using qualitative analysis software (Atlas.ti). The results indicated that outdated infrastructure, poor governance, and farmers’ non-payment of irrigation service fees hamper sustainable water management. Greater trust and communication within the WCAs would make an important contribution to effective collective action and to the long-term sustainability of local associations.

In Uzbekistan, generally practiced methods of irrigating crops are varieties of flooding (basin, border and furrow). These practices have created problems of waterlogging, salinity and lower irrigation efficiency. Waterlogging and salinization already affect 50 percent of irrigated areas, and irrigation efficiency hardly reaches up to 50-60%. The Karshi Steppe of Kashkadarya region is among the prime cotton and wheat producing areas in Uzbekistan, using around 4.5 – 5.0 billion m3 of irrigation water within a hydrological year. About 75% of this water is abstracted from Amu Darya River in the territory of Turkmenistan and raised up to 135 meters, using a cascade of seven pumping stations to Karshi main canal. Research on implications of applying other irrigation technologies with different irrigation regimes on cotton crop are limited in Uzbekistan, especially under water scarce situations, such as in Karshi Steppe. This study targeted that knowledge gap and compared performance of cotton crop under different irrigation regimes with three technologies (furrows, gated pipes, and drip). The yield data ranged from 3.5 to 4.6 t ha-1, whereas water productivity (WP) values ranged from 0.44 to 1.20 kg m-3 and irrigation water use efficiency (IWUE) ranged from 0.51 to 1.41 kg m-3. The measured ranges of IWUE and WP are much wider compared with data available for Karshi Steppe. Due to cotton being sensitive to soil-moisture stress, lack of skillful technicians at site for irrigation scheduling has led to more water stress than was planned for, resulting in lower crop yields than expected.

The advantages of a nexus approach in addressing complex environmental challenges are becoming increasingly clear. In Central Asia, however, the nexus between water–food–energy has not received adequate attention, as the very few studies that have been conducted fell short of quantifying nexus trade-offs and benefits at a practical, small scale. This paper applies a quantitative accounting method to assess water and energy use intensity in irrigated areas of the Karshi Steppe of Central Asia that are supplied by pumping water uphill (lift-irrigated) from the underlying river. The results indicated that the potential water and energy savings as well as the greenhouse gas (GHG) emission reductions could be achieved by applying an optimal planning deficit irrigation schedule simulated using CROPWAT 8. Some 575 MCM (million cubic metres) of water and 259 GWh of electricity can be saved, while the CO2 equivalent emissions can be reduced by almost 122 000 t. Achieving these savings requires a mix of technical and policy components. This paper describes an example of proper irrigation planning as a tool for water/energy savings and consequent reduction of CO2 emissions.

This paper applies quantitative accounting method to assess water and energy use intensity in irrigated areas of Zafarabad District of Central Asia that are supplied by pumping water uphill (liftirrigated) from the underlying river. The results indicated that the potential water and energy savings could be achieved by applying optimal planning irrigation schedule simulated using Cropwat-8. Some 81 million cubic meters of water and 67 GWh of electricity can be saved while the costs can be reduced by almost 163 thousand USD. This paper describes an example of proper irrigation planning as a tool for water/energy savings and consequent reduction of costs towards water pumping.

Reference evapotranspiration (ETo) is a key factor in determining the amount of water needed for crops, which is crucial to correct irrigation planning. FAO Penman-Monteith (EToPM) is among the most popular method to estimate ETo. Apparently sometimes it is difficult to compute ETo using Penman-Monteith due to challenges on data availability. FAO Penman-Monteith method requires many parameters (solar radiation, air temperature, wind speed and humidity), while Hargreaves-Samani method calculates ETo based on air temperature. Because Central Asia is a data limited region with weather stations unable to provide all required parameters for the PM method, this study aimed to estimate ETo using the Hargreaves and Samani (HS) method in Karshi Steppe, in Kashkadarya province, in southern Uzbekistan, based on data from 2011 to 2017. Reference evapotranspiration calculated by non-modified HS method is underestimated during the summer months. The reason for this underestimation might be higher air temperature and wind speed during these months. Therefore, the HS method in its original form cannot be used in our study area to estimate ETo. Modification of the EToHS, through application of a bias correction factor, had better performance and allowed improving the accuracy of the ETo calculation for this region. The calculated ETo values can inform decision making and management practices regarding water allocation, irrigation scheduling and crop selection in dry land regions of Amudarya river basin and the greater Central Asia area.

Potato is a very important cash crop in Uzbekistan as the government has implemented several measures to increase its production to meet food security as well as to improve its export potential. However, irrigation water demand of potato is much higher than for other crops such as sorghum and maize, which normally consume less water and generate more income. Furrow irrigation is the main irrigation method used to grow potato in Uzbekistan. Introduction of improved irrigation methods could reduce the water used for potato production and provide alternative solutions to improving potato production and income security under water scarce conditions. There are few comparative studies on conventional furrow versus improved irrigation methods for potato production.
This paper explores water productivity of two varieties of potato under four irrigation treatments in Andijan and Ferghana regions of Uzbekistan. At each location, four different irrigation treatments were evaluated. These four treatments were: conventional furrow irrigation (CFI), high frequency furrow irrigation (HFI), partial root zone drying irrigation (PRD), and drip irrigation (DrI). The experimental sites in each study area were established in 2012 on farmer fields. Data on water used and agronomic performance were collected from both study sites to calculate water productivity for each treatment. Analysis of Variance (ANOVA) was used to identify differences in treatments. The results indicate that, overall, high frequency furrow irrigation and drip irrigation treatments performed better than conventional furrow irrigation and partial root drying treatments.
Research findings from this paper are useful for relevant stakeholders in Uzbekistan whose population is highly dependent on irrigated agriculture. Existing water use policies in Uzbekistan do not provide water users incentives for water saving as water delivery for agriculture is highly subsidized by the government resulting in excessive water use. These findings may help reduce unsustainable water use by increasing knowledge of relevant stakeholders including decision makers in order to improve water policies in the region.
