Imperfections of the water management mechanism in the Isfara small transboundary river basin

Surface irrigation is associated with considerable water losses, uneven root zone moistening, increasing irrigation-induced soil erosion, low labor productivity of irrigators, low irrigation system efficiency, etc.

The principle of stakeholder engagement in decision-making associated with water management of small transboundary river;

IWRM planning technique

Low-pressure impulse mist irrigation system

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:

- Construction of low-pressure impulse mist irrigation system (procurement of polyethylene piping, pumping unit, cassette filter);
- Installation of pumping equipment, settling pond, impulse mist sprinkling nozzles.

Results:

Financial and economic:

rational use of irrigation water; enhanced efficiency of water and land resources use; low cost ($4,164/ha) compared to the basic option ($4,326/ha).

Ecological:

no damage to atmosphere, water and soil and production of ecologically clean agricultural produce.

Technical:

the system operates under low pressure enough to ensure sufficient mist sprinkling irrigation (high-quality artificial rain) creating the necessary microclimate stimulating proper plant growth and development, ensuring even and highly uniform soil moistening; the system is easy to assemble and operate.

Social:

reduced irrigation costs on behalf of water users due to smaller volume of consumed irrigation water; increased profitability of farms due to higher crops productivity.

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:

Low-pressure impulse mist irrigation system allows improving the overall conditions in greenhouses and/or lemon tree nurseries – rain-like water distribution curbs irrigation-induced soil erosion and unproductive water losses in the course of irrigation.

Recommendations:

It is necessary to widely deploy low-pressure impulse mist sprinkling systems with the aim of irrigation automation and saving irrigation water.

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: Low-pressure impulse mist sprinkling system for greenhouses and/or lemon tree nurseries.

Project duration: Apr 2012-Oct 2013.

Project goal and objectives: development and deployment of new low-pressure impulse mist irrigation system for greenhouses and lemon tree nurseries in the context of acute water shortage to ensure even distribution of irrigation water, exclude irrigation-induced soil erosion and unproductive irrigation water losses, thus, leading to water and power saving.

Project beneficiaries: “Ziroatkor” Farm.

Project implementer: Sh. Shotemur Tajik Agrarian University
