Local specifics | 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. |

Tools used in the practice | Technology of furrow-based counter irrigation |
Технология лазерной планировки орошаемых земель |
Description of the practice and its results | 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

Лазерная технология первоначально применялась при освоении целинных земель для капитальной планировки земель. Позже она стала применяться для текущей планировки. В последние годы из-за нехватки ресурсов практика использования лазерной технологии почти прекратилась, но на данном примере видно - насколько применение этого инструмента актуально в настоящее время.

Lessons learnt and recommendations made | 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. |
Уроки: Эта практика показывает необходимость периодической текущей лазерной планировки орошаемых земель для повышения эффективности орошения. Рекомендации: Применение лазерной технологии для текущей планировки орошаемых земель желательно сочетать с глубоким рыхлением земель |
