Специфика местности, где использована практика | Khorezm Region lies in the northwest of Uzbekistan (between the latitudes of 40N and 42N and longitudes of 60E and 62E). The Region stretches for 280 km from northwest to southeast, and for 80 km – from west to east. The adyr relief is mainly formed by moist-type playa and, to a lesser extent, by meadow and grey-dessert soils; the depressions relief is formed by sands. |

Описание практики и ее результаты | Technology applicability In the majority of Central Asian countries, irrigated agriculture is based on flooding irrigation (ex.: wheat) and/or furrow-based irrigation (other crops). Against the background of climate change and global water shortage, the traditional and/or currently practiced irrigation methods have lost their relevance and are no longer justified, in particular, in the Aral Sea area. In addition, watering the whole field of uneven relief based on traditional furrow-based technique requires long time. In many cases, traditional watering leads to uneven water distribution (alternating dry and bogging spots) across the field and rising ground water level. The suggested technology of counter irrigation is suitable for watering areas with even/flat relief, i.e. flat/lowland territories of Central Asian countries. Technology description The technology is quite simple and consists of simultaneous irrigation of a field from two sides. It was appraised in Uzbekistan’s northwestern part within the framework of the ZEF/UNESCO Project. The technology’s pilot application demonstrated that furrow-based counter irrigation can be used as a technical option of irrigating undeviating (even) sites and increases water efficiency due to more uniform water distribution along furrows. This effective water-conservation technology has been already widely tested in Central Asian countries, including Uzbekistan (Syr Darya and Khorezm Regions) by SANIIRI. Advantages

Actions: The participants were offered to undergo 2 exams (written and oral) within the framework of the Olympiad. Finalists of the written test could go on to the oral exam. Results: 1 student was selected from among the candidates to participate in subsequent Regional IWRM Olympiad and the International Summer School “Methods and Means of Assessing, Modelling and Monitoring the Water and Land Resources of Central Asia” to take place in Almaty City. |
Какие уроки и рекомендации можно извлечь из практики | Lessons learnt: The furrow-based counter irrigation technology is rather simple (entails simultaneous irrigation of a field from both sides) and represents a justified technical option of irrigating undeviating (even) relief land and increasing water efficiency due to more uniform water distribution along furrows. Recommendations: The irrigation technology is recommended for application by farmers prior to controlling ground water level and enhancing land reclamation condition via more radical measures. Under the condition of available investment, this watering method can be widely introduced on engineered basis. |
Formally, this competitive practice is routine while selecting the personnel/specialists for international and national projects, but their unbiased selection is not achieved in all cases. Quite often, various types of project participants are selected by way of “pulling strings” or based on the instruction of upper-tier agencies. |
