Water management in the Soviet period was organised according to ‘water-use regions’ or ‘irrigation districts’ depending on the different type and use of water supply systems. Some districts were fed only with groundwater from deep drillings, and others from large pumping stations which diverted river discharge to irrigation canals, while in other cases a conjunctive use of surface and groundwater was applied (Thurman 2001). In many cases, the irrigation zones (districts) crossed republican boundaries (Wegerich et al. 2012; Pak and Wegerich 2014). In the Syr Darya basin in the Ferghana Valley, for instance, there were six irrigation districts, of which three were transboundary. The transboundary districts incorporated irrigated areas from nearly all the CA countries (Fig. 5.2). For example, the Chakir District incorporated irrigated areas in Kazakhstan, Kyrgyzstan, and Uzbekistan, while the Mid-stream District incorporated irrigated areas in Kazakhstan, Tajikistan, and Uzbekistan (Wegerich 2015).
