Problem solved through this practice

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

Flooding of settlements; salination of irrigated land

Tools used in the practice

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

GIS-technologies and remote-sensing tools

Description of the practice and its results

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.

In 1980, specialists of NPO SANIIRI (Research and Development Association “Central Asian Research Institute of Irrigation”) designed and for the first time applied this type of drainage in the Qarshi Steppe where it demonstrated its efficiency.  The project was suspended due to lack of funding.  The re-launch of the project and installment of a combined drainage system in Kuva District (2010) once again confirmed its high efficiency and profitability, especially in areas of confined underground waters.  Further on, the model was applied in Rishtan, Altyarik and Baghdad Districts where it is successfully working.

Actions:

  1. reconstruction of the open collector;
  2. construction of the combined drainage system;
  3. operation of the combined drainage system;
  4. consultations with local experts on designing and constructing combined drainage systems;
  5. holding a training for Basin Irrigation System Administration (BISA) and Reclamation Expedition (RE) personnel on combined drainage system operation;
  6. development and distribution of training materials.

Results:

Financial and economic:

Specific construction costs (sum/ha) of the combined drainage system were twice less compared to horizontal drainage models.  Vertical drainage of 1 hectare of land requires 700-800 kWh of energy, whereas the combined drainage is hyperpiestic.  Maintenance costs for combined drainage systems are also much lower compared to horizontal and vertical drainage models – specifically, twofold less than for closed horizontal and threefold less for vertical. The combined drainage systems also allowed increasing crops productivity.

Technical:

The reclamation condition of farm land has improved.

Lessons learnt and recommendations made

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:

The practice has confirmed its high efficiency and profitability of combined-type drainage, especially in areas with confined underground water.

Recommendations:

It is necessary to widely apply combined-type drainage where hydro-geological conditions allow it.
