Описание практики и ее результаты |
The river originates in Kyrgyzstan in Ak-Suu Glacier on the northern slope of the Turkestan Ridge 3,193 m above sea level. The Ak-Suu ruins are located close to the river source. Near the settlement of Karavshin, the river is called the same name. Crossing the national border, the river merges with the Kshemysh River (Kshemyshsai) and, further on, the river receives the name of Isfara.
Actions:
Establishment of stakeholder groups, i.e. Small Basin Councils (SBC) representing local authorities, NGOs, water users and local communities. SBC secretariats independently hold internal semi-annual meetings. Thus, the SBCs serve as platforms to exchange opinions and information as well as take joint decisions associated with the enhancement of the overall situation in the river basin.
Results:
Creation of national Small Basin Councils (SBC) on the Isfara River allowed a platform for exchanging opinions and information as well as for drawing joint decisions to improve the overall situation in the Isfara River Basin, including the development of the IWRM basin plan for the target basin. |
Actions:
- Water supply using PPL-50 is possible from: a) reinforced concrete trays, b) covered network, c) temporary earthen water distributers;
- Prior to watering, the trays are manually distributed along the route and installed with required inclination perpendicular to the furrows in the beginning of the irrigated site. Sections are inserted into each other;
- After adjustment, the kit is capable of ensuring the desired watering regime;
- In case of long furrows (150+ m) layer watering is used with the application of flexible polyethylene film hoses (D=300 mm);
- Depending on specific site conditions, inter-row spacing and crop type, the size of irrigation streams is regulated by way of adjusting the water supply control gate.
Results:
- 20-30% reduction of field unproductive losses;
- Increased productivity (2-4 dt/ha for wheat, 3-4 dt/ha for cotton);
- At least twofold increase of irrigator labor productivity;
- Increased land use ratio (1.5-2.5%).

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 hold thematic seminars to ensure sustainability of SBC operations in the future. In the long term, it might be possible to establish a joint body to manage the whole river basin. |
Lessons learnt:
PPL-50 can be used for watering cotton with 0.9 and 0.6 m row-spacing as well as vegetable and cucurbit crops with 0.3 m row-spacing.
Recommendations:
It is recommended to apply:
- PPL-50 (D=300 mm) in steep foothill conditions;
- PPL-50 (D=500 mm) in flat terrain;
- Prior to using the system in flat terrain conditions, it is desirable to do land planning.

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 Isfara small transboundary river basin, specialists of water and environmental agencies, farmers.
Project implementer: USAID/CAREC. |
Project title: Adaptation of contour furrows and layer watering via portable trays: research on establishing permanent furrows on the premises of Baikazan Farm of Parkent District.
Project duration: 2005-2006.
Project goal and objectives: improve local living standards and food security among rural residents as well as preserve soil fertility in farms located on sloped terrain by way of watering via contour furrows based on the greatest inclination and layer arrangement of assembly polyethylene trays. The short-term project objective was to demonstrate the technology of watering via contour furrows based on the greatest inclination of sloped terrain and layer arrangement of assembly polyethylene trays.
Project beneficiaries: farms and dekhan farms.
Project implementer: ICARDA |
