Low level of coordination among WUAs – as a rule, each WUA liaises independently with its water management organization (WMO).

Deficiency of irrigation water during certain periods of vegetation

Methods of integration and social mobilization

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 AAMC-WUU is an association of legal entities in the form of Union – a voluntary independent non-profit public organization uniting legal entities (i.e. WUAs) based on common interests with the aim of coordinating actions and protecting shared interests and rights.  AAMC-WUU operates as per the Charter approved at the general meeting of water user representatives, has its own stamp and bank account.

Actions:

The creation of AAMC-WUU began with the establishment of the Initiative Group (IG).  The IG consisted of active water specialists, representatives of water users and other stakeholders who saw the need to transit to IWRM.  Further on, the IG carried out social mobilization, drafted necessary documents (the Union’s Charter, etc.), organized the general meeting of water users that approved the Charter and established the Union’s Council (Board).  After that, AAMC-WUU underwent legal registration and officially launched its work.

Results:

• AAMC-WUU established, legally registered and has been operating until present time;
• AAMC-WUU contributed to the following:
  - enhanced stability and uniformity of water supply to WUAs via state WMO;
  - better collection of water supply service fees paid by WUAs to state WMO.
• Representing the interests of water users as a member of the RMC Water Committee, AAMC-WUU also contributed to decreasing conflicts between WUAs and WMO.

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:

The effectiveness of AAMC-WUU depends on internal and external conditions: capacities (financial, institutional, etc.) of its members (i.e. WUAs) and the level of democracy and market development in a given country.  In turn, the growth of capacities of AAMC-WUU members depends on AAMC-WUU performance.

Recommendation:

Currently, WUAs capacities are rather poor which is reflected in AAMC-WUA own underperformance.  Considering that WUA represent the weakest link in water hierarchy and the role of water users in addressing national food, water and environmental security needs, the government should find opportunities to support (first of all, financially) WUAs/AAMC-WUU during transition period (until they become self-sufficient).

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.

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: WUAs, farmers in project sites.

Project implementer: IWMI, SIC of the ICWC, Project Steering Committee (PSC) consisting of 3 representatives of the Ministries of Rural and Water Management (MRWM) of project target countries, 3 heads of Regional Water Administrations hosting project target sites.

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.
