GIS-technologies and remote-sensing tools |
Описание практики и ее результаты |
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.

Before the introduction of GIS-technologies, REs performed all operations – including production of maps, identification of areas suffering from land salination, level of ground water mineralization, etc.
Actions:
- Enhancing the technical capacity of REs: provision of necessary equipment and tools, licensed GIS software, GPS devices, equipment for chemical analysis, etc.
- Enhancing personnel capacities:
- Trainings and consultations of the personnel of Basin Irrigation Water Administrations (BIWAs) and REs abroad and in Uzbekistan;
- Consultations by foreign and local GIS experts;
- Development and distribution of training materials.
Results:
Financial and economic:
Reduction of the number of drafting technicians, saving on stationery, etc.
Technical:
Increased productivity and quality of works by RE office personnel. |
Какие уроки и рекомендации можно извлечь из практики |
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. |
Lessons learnt:
The practice has demonstrated the possibility and efficacy of successful and effective application of GIS-technologies for reclamation as well the overall demand for GIS-technologies and GIS-specialists in other areas (after project completion, the “drain” of GIS-specialists to other industries/organizations started).
Recommendations:
Financial incentives are necessary to keep GIS-specialists in the water sector. It is necessary to scale-up the GIS-practices in other regional REs of Uzbekistan and irrigation-related organizations, including Water User Associations (WUAs). |
