Water erosion, discharge, uneven distribution of irrigation water, poor yields

Insufficient level of objectivity while selecting candidates, i.e. selection of final candidates not based on their knowledge and skills but illicitly

Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S)

Technique of knowledge assessment

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:

The participants were offered to undergo 2 exams (written and oral) within the framework of the Olympiad.  Finalists of the written test could go on to the oral exam.

Results:

1 student was selected from among the candidates to participate in subsequent Regional IWRM Olympiad and the International Summer School “Methods and Means of Assessing, Modelling and Monitoring the Water and Land Resources of Central Asia” to take place in Almaty City.

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.

Formally, this competitive practice is routine while selecting the personnel/specialists for international and national projects, but their unbiased selection is not achieved in all cases. Quite often, various types of project participants are selected by way of “pulling strings” or based on the instruction of upper-tier agencies.
