Country: Kazakhstan Province: Jambyl Region |
Local specifics | The site is located in the desert foothill plain in South-ern Kazakhstan (internal drain area) at the very end of Sharuashlyk Irrigation Canal. |
The site is located in the foothills with significant difference in elevation |

Problem solved through this practice | 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). |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
Tools used in the practice | Method of autumn and winter water-charging irrigation |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
Description of the practice and its results | Actions: Results: Financial and economic: Technical: |
Actions: Deployment of the Simultaneous Impulse Sprinkling Kit (KSID-10S) allowing extremely uniform and simultaneous dispersion of irrigation water across all sections of arable pasture or hayfield meadow. Water expenditure at the impulse device makes 0.05-0.3 l/sec and 0.25-2.0 l/sec in the irrigation pipeline, thus, reducing (3-4 times) the costs associated with the pipeline network installation compared to other sprinkling systems (kits). The pipeline network is built of 15-25 mm diameter pipes easy to transport and assemble in mountainous conditions. Technical characteristics: Operation modes: automatic and manual Irrigated area: 10 ha Water consumption: up to 100 m3/day Average sprinkling (rain) intensity: 0.002-0.008 mm/min EFFICIENCY: 99% MOC: 98% Watering automation level: 100%

Lessons learnt and recommendations made | 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: The advantages of impulse sprinkling irrigation were confirmed by the research efforts on other test sites of KAZNIIVKh in Jambyl Region that allowed increasing biological productivity of Golden Delicious apple variety by 10.1-36.8%, and commercial productivity – by 16.6-49.4% compared to conventional sprinkling irrigation systems. Recommendations: It is necessary to continue application of similar practices in foothill areas in Central Asia subject to power supply shortages. |

Brief information on the project | 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 |
