Application of water productivity analysis can provide clues in the search for solutions to solve water management problems of central Asia. It is in this context that this paper provides an analysis of water productivity both spatially and temporally in the cotton and rice production areas of Syr Darya Basin of central Asia. The spatial analysis includes different farm types and basin segments, and the temporal analysis includes 3 hydrological years during 1999–2001. The analysis of temporal data showed that in water-deficient years, water productivity, both in terms of supply and evapotranspiration, is higher than the same in water-abundant years. The data also show that type and size of farms have an impact on water productivity in the case of both cotton and rice. This study concludes by suggesting strategies and options for enhancing the average water productivity both in the cotton- and rice-growing areas of the Syr Darya Basin.

This report addresses a specific context of massive inequity and unevenness in water allocation and distribution experienced presently by the water users in transitional Central Asian economies, as a result of broad-scale fragmentation of the previously large farms. The report describes action research aimed at making water distribution at the tertiary level more reliable, transparent and equitable.

Water conservation is essential to prevent salinity and land degradation in Central Asia. Therefore, field-testing and evaluation of water conservation methods, i.e. laser land leveling in new farming systems of Central Asia is important task. This in mind the International Water Management Institute (IWMI) and its regional partner on IWRM FV (IWRM FV project – Integrated Water Resources Management in Ferghana Valley project is funded by Swiss Development Cooperation (SDC) and conducted jointly with IWMI and Scientific Information Center of Interstate Coordination Water Commission (SIC ICWC) in the Ferghana Valley of Central Asia) project SIC ICWC have conducted 3 year study of impacts of the Laser leveled land leveling on water use, productivity and crop yields in northern Tajikistan. The major research question was laser land leveling an effective water saving tool in the new context of land use and ownership on smaller private plots. Can farmers afford the costs of laser land leveling and how economically viable is it? These research questions were studied in 5 ha laser leveled and neighboring non-leveled (control) fields for 2004–2006. The results showed that laser land leveling can reduce the water application rate in 2004 by 593 M3/ha, in 2005 by 1509 M3/ha and in 2006 by 333 M3/ha in comparison with the unleveled field, located in the similar agro-ecological conditions. The deep percolation was 8% lower and run off 24% less than in non-leveled field. The average annual net income from the laser field was 22% higher than that from the control field. The gross margin from the laser-leveled field were 16. 88 and 171% higher compared to that from the control field for 2004, 2005 and 2006, and on average was 92% higher. In spite of these positive results, there are hindrances on wide application of laser land leveling in Tajikistan. These are absence of initial capital of farmers and scattered land location.

Continuous institutional changes in the rural sector in Central Asia have negatively affected the reforms and the development of other related sectors, e.g. the irrigation sector. Therefore, reforms in the irrigation sector have been carried out in an ever changing and uncertain environment. Institutional changes have so far been aimed the farm level that was formerly managed by collective and state farms. Replacement of relatively few collective farms by thousands of individual farming units has resulted in chaos and anarchy in water management at on farm level. Water Users Associations (WUAs) were introduced in Kyrgyzstan to better organize farm level water management. The key questions concerning WUAs in Kyrgyzstan at present are: Do they provide better service for farmers in delivering water? Do irrigation services result in good crop yields? Are they financially viable? In order to answer these questions, the irrigation performance of four WUAs located within one main canal area in Osh province of Kyrgyzstan were assessed for the period 2003-2005. The analysis indicates that in spite of intense international support, WUAs in the study area were performing relatively poorly on irrigation service provision. However, there are signs of improvement, such as increasing water productivity, reduced water use and improved financial sustainability. The Kyrgyz experience on transformation of on-farm level water management from collective farms to WUAs can provide good examples for neighboring countries, e.g. Tajikistan, Uzbekistan, where agricultural restructuring has only started recently.
