Extremely low water availability (supply) of pastures; the quantity of cattle in watering sites below standard; land erosion

Flooding of settlements; salination of irrigated land

Technology of springs arrangement for stock watering

GIS-technologies and remote-sensing tools

Actions:

At first, the exact location of water outcrop was identified and cleaned from mud.  15 meters below the outcrop, 3 interconnected water tubs were installed (each 1.8 m long, 0.5 m wide and 0.5 deep).  Each subsequent tub is located lower than the preceding one, thus, allowing water flowing down in the cascade manner.

Results:

Financial and economic:

Cattle gaining weight quicker.

Technical:

Improved water supply in the area, including for cattle watering.

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:

Collection of water in one place had been practiced since ancient times, but was forgotten over time.  Rehabilitation of traditional practices should be welcomed.

Recommendations:

Similar practices should be scaled-up and continued as they not only benefit the local population, but also allow enhancing water availability for wild animals and expanding hayfield meadows.

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.

Traditional tools transferred from generation to generation which demonstrate their relevance in modern conditions

Project title: Application of GIS-technologies for reclamation.

Project duration: Jan 2010-Dec 2012 (3 years).

Project goal and objectives: comprehensive support of Reclamation Expedition (RE) specialists; introduction of new technologies; enhancing RE technical capacities to ensure a more expedient implementation of projects to improve the reclamation condition of irrigated land with the aim of receiving better agricultural yields with the simultaneous maintenance of environmental equilibrium in the area.

Project beneficiaries: Fergana Region and Syr Daria Region Reclamation Expeditions.

Project implementer: Management Department of the Foundation for Reclamation Improvement of Irrigated Land.
