Проблема, которая решается применением практики | Acute water shortage; land degradation in the village of Sadu Shakirov; abandoned irrigated arable lands used only for year-round cattle grazing. For a long time, the irrigation canal was not operation-al and, thus, became dilapidated. The situation in the area was aggravated by climate change impacts (de-creased quantity of early spring, summer and winter precipitation, increased average annual temperature, spring and autumn frost bites and summer droughts). |
Surface irrigation is associated with considerable water losses, uneven root zone moistening, increasing irrigation-induced soil erosion, low labor productivity of irrigators, low irrigation system efficiency, etc. |

Low-pressure impulse mist irrigation system |
Описание практики и ее результаты | Actions: Results: Financial and economic: Technical: |
Actions: - Construction of low-pressure impulse mist irrigation system (procurement of polyethylene piping, pumping unit, cassette filter); Results: Financial and economic: rational use of irrigation water; enhanced efficiency of water and land resources use; low cost ($4,164/ha) compared to the basic option ($4,326/ha). Ecological: no damage to atmosphere, water and soil and production of ecologically clean agricultural produce. Technical: the system operates under low pressure enough to ensure sufficient mist sprinkling irrigation (high-quality artificial rain) creating the necessary microclimate stimulating proper plant growth and development, ensuring even and highly uniform soil moistening; the system is easy to assemble and operate. Social: reduced irrigation costs on behalf of water users due to smaller volume of consumed irrigation water; increased profitability of farms due to higher crops productivity. |
Какие уроки и рекомендации можно извлечь из практики | Lessons learnt: Application of water-charging irrigation demonstrated the efficiency of water use and allowed local popula-tion to go through winter without losing livestock. Recommendations: |
Lessons learnt: Low-pressure impulse mist irrigation system allows improving the overall conditions in greenhouses and/or lemon tree nurseries – rain-like water distribution curbs irrigation-induced soil erosion and unproductive water losses in the course of irrigation. Recommendations: It is necessary to widely deploy low-pressure impulse mist sprinkling systems with the aim of irrigation automation and saving irrigation water. |

Краткая информация о проекте | Project title: Fall and early spring Irrigation of arable land and pastures as an adaptation mechanism of ra-tional water use in Southern Kazakhstan Duration: May 1, 2008 – April 30, 2009 Project goal and objectives: reduce land degradation due to climate change by way of rational use of irriga-tion water. The project was implemented to prevent loss of cattle due to forage shortage during alternating droughty years. Project beneficiaries: local population. Project implementer: Kogal LLC |
Project title: Low-pressure impulse mist sprinkling system for greenhouses and/or lemon tree nurseries. Project duration: Apr 2012-Oct 2013. Project goal and objectives: development and deployment of new low-pressure impulse mist irrigation system for greenhouses and lemon tree nurseries in the context of acute water shortage to ensure even distribution of irrigation water, exclude irrigation-induced soil erosion and unproductive irrigation water losses, thus, leading to water and power saving. Project beneficiaries: “Ziroatkor” Farm. Project implementer: Sh. Shotemur Tajik Agrarian University |
