The site is located in the desert foothill plain in South-ern Kazakhstan (internal drain area) at the very end of Sharuashlyk Irrigation Canal.

Foothill droughty area; extremely water pervious soils with pebble bed; the site is located below the Zhijdalisoj Water Reservoir

Acute water shortage; land degradation in the village of Sadu Shakirov; abandoned irrigated arable lands used only for year-round cattle grazing.

For a long time, the irrigation canal was not operation-al and, thus, became dilapidated. The situation in the area was aggravated by climate change impacts (de-creased quantity of early spring, summer and winter precipitation, increased average annual temperature, spring and autumn frost bites and summer droughts).

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

Method of autumn and winter water-charging irrigation

Free-flow drip irrigation system (DIS)

Actions:
1) Reconstruction of the canal, stop-gates and field irrigation networks (rehabilitation of irrigation furrows),
2) Setting up artificial pastures with forage crops

Results:

Financial and economic:
Using water-charging irrigation for rangelands allowed increasing their productivity from 3.5 to 5 dt/ha and receiving 60 tons of herbage for cattle and sheep and goats from non-cultivated land.

Technical:
1) 12 km of the canal and 5 stop-gates to regulate water releases restored,
2) 5 km of irrigation furrows built,
3) Cultivated pastures with forage crops created (soil preparation, alfaalfa planting, coordination of irrigation norms),
4) Fields are prepared during the summer-fall period, and watered during late fall or early spring.

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:
Application of water-charging irrigation allowed in-creasing water availability and, as the result, productivity of agricultural crops.

Application of water-charging irrigation demonstrated the efficiency of water use and allowed local popula-tion to go through winter without losing livestock.

Recommendations:
The method can be used in areas/communities where along with crop growing the population is also involved in livestock breeding.

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 that proved their efficiency in modern conditions

Project title: Fall and early spring Irrigation of arable land and pastures as an adaptation mechanism of ra-tional water use in Southern Kazakhstan

Duration: May 1, 2008 – April 30, 2009

Project goal and objectives: reduce land degradation due to climate change by way of rational use of irriga-tion water. The project was implemented to prevent loss of cattle due to forage shortage during alternating droughty years.

Project beneficiaries: local population.

Project implementer: Kogal LLC

Project title: Innovative science and technological work “Introduction of DISs using natural water pressure in areas adjacent to foothill water reservoirs”.

Project duration: 2013-2014.

Project goal and objectives: create DISs operating without pumping equipment.

Project beneficiaries: employees of Zhijdalisoj Water Reservoir of the Naryn-Syr Darya BISA (Basin Irrigation System Administration).

Project implementer: State Committee on Science and Technology  of the Republic of Uzbekistan (SCST of the RUz).
