| Local specifics |
The site is located in the foothills with significant difference in elevation |
The settlements are located in the river catchment area; deep ground water occurrence; mountain valleys are under high risk of mudflows and floods. |

| Problem solved through this practice |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
Water deficit; settlements and agricultural land under flood and mudflow threat during mudflow risk periods |
| Tools used in the practice |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
Cascading storage pools (reservoirs) accumulating rain and runoff water |
| Description of the practice and its results |
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%
Results:
- Ensured water supply according to crops requirements with the account of changing weather conditions and moisture deposits in active soil layer;
- Elimination of : 1) water-induced soil erosion, 2) puddling and 3) discharge run-off;
- No need for water recirculation among irrigation sections.
|
Actions:
- assessment of mudflow and flood risks and surveying local population regarding reservoirs’ locations and water uses (drinking and irrigation water supply);
- designing reservoirs;
- construction of reservoirs with the engagement of local residents;
- training of local residents on servicing reservoirs and corresponding equipment.
Results:
- reduced risks for public life and health;
- enhanced water supply of irrigated land;
- reduced risk of agricultural losses due to drought;
- reduced risk of biodiversity damage caused by mudflows and floods;
- enhanced public access to drinking water.

| Lessons learnt and recommendations made |
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. |
- Cascading reservoirs provide better cumulative effect at lower cost compared to separate reservoirs;
- Application of modern water-proofing materials during the construction of storage pools (reservoirs) allows to reliably store winter and spring runoff to be used during vegetation period.
