Water erosion, discharge, uneven distribution of irrigation water, poor yields |
| Описание практики и ее результаты |
The Aspara River originates in the Western Tien Shan on the territory of Kyrgyzstan and flows northwards crossing the border with Kazakhstan. The river’s total length exceeds 44 km, and its catchment area amounts to approximately 66 km2. The Aspara River Basin is located in Chu Region in Kyrgyzstan’s northwest and Jambyl Region in Southern Kazakhstan. The basin is shared by several different ethnicities where they live and work. The basin’s population is rapidly growing, and the agriculture is developing. In many places along the course of the river, especially in its lower streams, the water doesn't meet quality and sanitary standards. Liquid waste produced by the population, industry and livestock production as well as solid waste constitute major sources of environmental pollution.
Project efforts were carried out in Jambyl Region of the Republic of Kazakhstan and Chu Region of the Kyrgyz Republic.
Actions:
Establishment of 2 stakeholder groups, i.e. Small Basin Councils (SBC) – on both Kazakhstan’s and Kyrgyzstan’s sides of the river – representing local authorities, NGOs, water users and local communities. The SBCs already held 6 joint meetings proving the value of SBCs as platforms to exchange opinions and information as well as take joint decisions on enhancing the overall situation in the basin.
In addition, hydrometric posts were reconstructed and underwent certification, and the automated water distribution and accounting system was installed on the Mailybai Canal. The water supply system in the village of Cholok-Aryk also underwent reconstructed. A demo-site to demonstrate drip irrigation equipment and technology was established on the premises of Ravshan Farm receiving its irrigation water via the Mailybai Canal.
Results:
Thus, the creation of national Small Basin Councils (SBC) on the Aspara River ensured a platform for exchanging opinions and information as well as joint decision-making to improve the overall situation in the Aspara River Basin, including the development of the IWRM basin-specific plan. |
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.

| Какие уроки и рекомендации можно извлечь из практики |
Lessons learnt:
Introduction of IWRM principles is the pre-requisite of stable and fair water supply irrespective of a given water user’s location.
Recommendations:
Currently, when local stakeholders are represented in SBCs and are engaged in joint water management, it is necessary to continue the capacity-building efforts to build-up SBCs’ efficiency. In the long term, it might be necessary and possible to establish a joint body to manage the whole Aspara River Basin shared by Kazakhstan and Kyrgyzstan. |
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. |

| Краткая информация о проекте |
Development and implementation of basin plans constitute principal elements of integrated water resources management. Multi-agency coordination mechanism via basin councils or coordination groups is an important advantage of IWRM. This approach allows streamlined coordination and synergy of actions on all levels of management hierarchy.
Project title: Stakeholder partnership in joint policy-making: assistance to transboundary cooperation in small watersheds of Central Asia.
Project duration: Apr 2012-Oct 2016
Project goal and objectives: introduction of the integrated water resources management (IWRM) practice in three transboundary watersheds and its scaling-up in Central Asia.
Project beneficiaries: communities of the Aspara small transboundary river basin, specialists of water and environmental agencies, farmers.
Project implementer: USAID/CAREC. |
