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

Irrational use of irrigation water and fertilizers; deficit of electric power; low soil bonitet; poor crops productivity; poor quality of agricultural products; soil erosion

Technology of springs arrangement for stock watering

Free-flow drip irrigation system (DIS)

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.

Actions:

Free-flow DIS was installed at the Zhijdalisoj Water Reservoir and was connected to the already operating gravity irrigation piping network. Due to the elevation difference between the pipe inlet and outlet (at the point of entry to the irrigated site) the system generates natural water pressure allowing free-flow DISs installed in gardens to operate without any pumping equipment, i.e. electricity.

Results:

Technical:

thanks to free-flow DIS, water and fertilizers are distributed evenly, strictly according to corresponding norms, in due time and economically (water saving - up to 50%).

Financial and economic:

increased (by 30-40%) crop yields and improved yield quality.

350,000 sum/ha ($150/ha) saved due to electricity saving and no need to repair pumping equipment.

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:

Application of natural (gravity-based) water pressure allows making DISs more affordable for farms located on slope acreage of mountain foothills.

Recommendations:

It is necessary to carry out research to identify locations where free-flow DISs could work thanks to natural water pressure.

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

Domestic tools (outcomes of research by domestic R&D organizations)
