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. |
Объект расположен в полузасушливой зоне с острой нехваткой водных ресурсов в летний период. Деградация земель. |

Problem solved through this practice | Inefficient field-level use of irrigation water |
Степень водообеспеченности пастбищных земель очень низкая, количество перегона скота на водопой меньше, чем по нормативу, эрозия почв. |

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

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: Сбор воды в одно место практиковался с древних времен, но он со временем был забыт. Восстановление традиционного опыта следует приветствовать. Рекомендации: Нужно продолжать такие мероприятия, так как такие практики выгодны не только местному населению, но они обеспечивают водой и диких животных, а также увеличивают пастбищные сенокосные площади. |
