Problem solved through this practice |
Water erosion, discharge, uneven distribution of irrigation water, poor yields |
- Prior to the implementation of the IWRM-Fergana Project, SFMC was managed based on the territorial principle by 3 water management organizations (WMOs): Andizhan Regional Water Administration, Operation Department of the Main Fergana Trunk Canal, and Fergana Regional Water Administration.
- On the borders between regions and districts (especially between Andizhan and Fergana Regions (Polvontosh Hydro Section)) frequent water distribution related conflicts took place;
- The quality of water management (uniformity, stability and efficiency of water supply) was poor.

Tools used in the practice |
Technique and technology for irrigation based on Simultaneous Impulse Sprinkling Kit (KSID-10S) |
The hydro-graphic principle of main trunk canal management |
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:
Instead of 3 WMOs established based on the territorial-administrative principle, one organization (Administration of the Southern Fergana Main Canal, ASFMC) was created on the basis of the hydro-graphic principle. ASFMC is fully responsible for maintenance and operation of the SFMC from the point of water intake to the very end of the canal (see figures).
Results:
Transition to the hydro-graphic principle of establishing WMOs allowed to do the following:
- sharply decrease the number of water conflicts on the borders between regions and districts;
- enhance the uniformity (fairness) of water resources distribution;
- enhance the stability of water supply;
- reduce organizational losses.

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. |
Lessons learnt:
- Transition to the hydro-graphic principle of establishing WMOs constitutes an institutional tool of improving the quality of water management as it allows implementing a more objective and fair water management policy less dependent on local authorities;
- Local authorities are not interested in transiting to the hydro-graphic principle and demonstrate resistance to the process.
Recommendations:
Transition to the hydro-graphic principle should be preceded by the following:
- comprehensive analysis of water allocation issues along the target main canal;
- training aimed at educating water-related personnel and decision-makers on integrated water resources management (IWRM).

Brief information on the project |
|
Project title: Integrated Water Resources Management in the Fergana Valley (IWRM-Fergana).
Project duration: Jan 01, 2001-Dec 31, 2012 (12 years).
Project goal and objectives: overall project goal was “to contribute to safer living, environmental sustainability and wide social harmony, to support rural restructuring in Central Asian countries by enhancing water resources management based on the example of the Ferghana Valley”.
Project beneficiaries: water users and water consumers within the project site.
