Akbura River Basin

Khorezm Region lies in the northwest of Uzbekistan (between the latitudes of 40N and 42N and longitudes of 60E and 62E). The Region stretches for 280 km from northwest to southeast, and for 80 km – from west to east. The adyr relief is mainly formed by moist-type playa and, to a lesser extent, by meadow and grey-dessert soils; the depressions relief is formed by sands.

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

Inefficient field-level use of irrigation water

Methods of integration and social mobilization

Technology of furrow-based counter irrigation

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.

Technology applicability

In the majority of Central Asian countries, irrigated agriculture is based on flooding irrigation (ex.: wheat) and/or furrow-based irrigation (other crops).  Against the background of climate change and global water shortage, the traditional and/or currently practiced irrigation methods have lost their relevance and are no longer justified, in particular, in the Aral Sea area.  In addition, watering the whole field of uneven relief based on traditional furrow-based technique requires long time. In many cases, traditional watering leads to uneven water distribution (alternating dry and bogging spots) across the field and rising ground water level.  The suggested technology of counter irrigation is suitable for watering areas with even/flat relief, i.e. flat/lowland territories of Central Asian countries.

Technology description

The technology is quite simple and consists of simultaneous irrigation of a field from two sides.  It was appraised in Uzbekistan’s northwestern part within the framework of the ZEF/UNESCO Project.  The technology’s pilot application demonstrated that furrow-based counter irrigation can be used as a technical option of irrigating undeviating (even) sites and increases water efficiency due to more uniform water distribution along furrows.  This effective water-conservation technology has been already widely tested in Central Asian countries, including Uzbekistan (Syr Darya and Khorezm Regions) by SANIIRI.

Advantages

• Water-saving – results of the system’s field pilot testing show that compared to traditional furrow-based irrigation counter watering allows saving up to 20% of irrigation water during vegetation season;
• Decreased seasonal land salination at furrow ends – land salination at furrow ends due to poor absorption of irrigation water and high capillarity can be reduced by half;
• Increased yields – application of the method allows increasing crop yields in general by 30-35%, and specifically for cotton – by 0.5 tons/ha;
• Application and design enhancements of furrow-based irrigation (discharge optimizing, washing irrigation, field laser planning) allow increasing the technology’s efficiency from the current 45% up to 65%.

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 furrow-based counter irrigation technology is rather simple (entails simultaneous irrigation of a field from both sides) and represents a justified technical option of irrigating undeviating (even) relief land and increasing water efficiency due to more uniform water distribution along furrows.

Recommendations:

The irrigation technology is recommended for application by farmers prior to controlling ground water level and enhancing land reclamation condition via more radical measures.  Under the condition of available investment, this watering method can be widely introduced on engineered basis.
