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

Deficiency of irrigation water during certain periods of vegetation

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

Technology of crop irrigation via ground water feeding the level of which is regulated by means of a control device installed in the observation well

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.

The gate devices used abroad are expensive and inconvenient as to their maintenance.  The control device designed by the ICWC Research Center allows regulating ground water level (GWL) by way of altering the device’s height (for example, its height can be 90 cm).  Besides, it is easily installed and dismantled after use.

Actions:

1. Selection and justification of the choice of a plot for potential drainage (admissible ground water mineralization should not exceed 3 g/l);
2. Detailed analysis of interaction between irrigation and drainage on the level of farms and WUAs (Water User Associations);
3. Mounting and installation of GWL control device;
4. Fitting the drained plot with modern tools and monitoring the elements of water-salt balance in the aeration zone;
5. Impact assessment of water supply and GWL regulation on soil humidity and salination, drainage discharge and drainage water mineralization as well as crops productivity.

Results:

Financial and economic:

• Low overall costs of the GWL control device compared to similar foreign devices;
• Increased (5-8%) productivity of winter wheat compared to control land plot.

Technical:

rational use of surface water.

Environmental:

reduced drainage.

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 approach has been proved as a constructive way of converting research outcomes into real-life solutions.  The approach will also help expanding the results of controlled drainage from the field level to the level of WUA and, over time, up to the level of irrigation system.

Recommendations:

It is necessary to scale-up the practice in other regions and districts with identical conditions of irrigated land and install this control model in other CHD zones.

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.

Project title: Management of irrigation and drainage systems for sustainable productivity growth in the Fergana Valley of Central Asia.

Project duration: Aug 2014-Dec 2015.

Project goals: improve irrigation and drainage systems and enhance the efficiency of crops watering.

Project objectives: manage GWL by way of controlling CHD with the aim of increasing crops water supply, enhance irrigation efficiency and decrease the amount of drainage and pollutants discharge; assess the influence of water supply and CHD regulation on soil humidity and drainage discharge; assess the difference of drainage and drainage water quality between controlled (managed) and conventional drainage models.

Project beneficiaries: target farm.

Project implementer: ICWC SIC.
