Desertification and decreased productivity of desert pastures due to over-grazing around existing cattle watering sites

• Uneven distribution of water to consumers (head-end issue),
• Unstable water supply to consumers,
• Significant organizational water losses

Technology of building sardobas (stone-dome covered water collection and storage reservoirs) to enhance pasture water supply

Principles of water rotation and public participation

Main actions:

• mudflow and flood risk assessment and surveying local population regarding sardobas’ locations.

Actions:

• selection of takyrs to construct sardobas jointly with local cattle-farmers;
• construction of sardobas jointly with local cattle-farmers;
• cleaning takyr surfaces.

Results:

• pastures that were not previously utilized due to absence of water sources returned to pasture rotation;
• pastures destroyed due to over-grazing started to restore;
• increased herd productivity due to reduced passage distances and higher fodder value of pastures.

Uniform and fair water distribution among water consumers (WCs) inside WUAs, clear alignment and coordination of water supply schedules via internal WUA networks of all levels with water supply schedules to WUA derivation canals from main canals is ensured by enhancing existing water distribution planning techniques based on water rotation (recirculation) and volumes of technically deliverable water executed via decade planning (within vegetation period decades).

Actions:

In accordance with the approved decade-based water distribution scheduled plan, decade water quantity is supplied to WCs in turns as per their water requests.  The schedules can be quickly adjusted depending on water availability in concerned water bodies.  The technique is based on wide engagement of WCs in distribution procedures – not only WUA personnel but also WCs themselves know who is receiving water, when and how much of it and, thus, can monitor each other and assess each other’s operations.  This promotes better mutual water discipline among WCs.  The process can be controlled from beginning to end based on corresponding documents (decade water distribution schedules, water request from WCs and WUAs, water request registration logs, water accounting logs at WUA headworks and WUA derivation canals.

Results:

As the result of introducing the decade-based water distribution plan in 2009-2011:

• actual water intake decreased, despite the fact that water supply to WCs remained high due to the increased efficiency of water distribution inside WUAs (90% of water availability) and ensured high yields;
• irrigation network efficiency rate rose from 0.69 to 0.79. The volume of water saved due to reduced losses along WUA irrigation lines made 8% of the total actual water intake;
• increased net incomes due to yield growth thanks to better water supply of key agricultural crops;
• drastic drop in the number of disputes and conflicts associated with not only water use but also financial, economic and institutional stability of WUAs;
• instead of mineralized collector and water, WCs located in the end sections of WUA networks started to get water safe for their crops.

Lessons learnt:

Construction of sardobas in takyr areas allows enhancing pasture water supply, thus, leading to the restoration of over-grazed pastures.

Recommendations:

The practice requires long-term planning and an integrated response with the early-on engagement of desertification experts (designing a set of measures to protect takyrs from sand drifts), state agencies (technical assistance) and pasture users (observance of pasture rotation schemes, prevention of takyrs from contamination and pollution).

Lessons learnt:

Thanks to proper water use management inside WUAs, water intake in the upper sections of main canals and rivers decreased by 50-80% and, thus, the unproductive discharge to collectors and depressions reduced also.  Reduced water intake in the head sections of main canals and rivers led to the increased influx of high-quality irrigation water in their end sections resulting in better observance of environmental requirements aimed at preserving wild flora and fauna.

Recommendation:

Country-wide scaling-up of the practice of decade-based water distribution planning inside WUAs is necessary and possible.
