Problem solved through this practice | 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). |
Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton |
Tools used in the practice | Method of autumn and winter water-charging irrigation |
Tubular water outlet flowmeter |
Description of the practice and its results | Actions: Results: Financial and economic: Technical: |
Actions: - Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles); Results: Financial and economic: saving of irrigation water; low cost of irrigation system automation (total kit cost: $500/ha) with the service life of 5 years. Technical: simple design allowing a more even distribution of irrigation water stream among furrows, thus, ensuring the prescribed water supply mode. Social: improved working conditions of irrigators; lower labor needs/costs; enhanced mutual trust among farmers and water users. |
Lessons learnt and recommendations made | Lessons learnt: Application of water-charging irrigation demonstrated the efficiency of water use and allowed local popula-tion to go through winter without losing livestock. Recommendations: |
Lessons learnt: Installation and deployment of tubular water outlet flowmeter allows to improve the uniformity of irrigation stream’s distribution among furrows and conduct irrigation water accounting. Recommendations: It is necessary to widely use the small-scale irrigation automation means like the tubular water outlet flowmeters which have simple design, are convenient to operate, are low-cost and mobile and ensure supply of the prescribed amount of irrigation water. |

Brief information on the project | 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: Watering technology based on tubular water outlet flowmeters. Project duration: Apr 2010-Oct 2011. Project goal and objectives: development and deployment of a crop watering technology for dekhan farms of the Republic of Tajikistan allowing to significantly increase the efficiency of water use. Project beneficiaries: members of “Istikol” WUA (Water User Association). Project implementer: Institute of Water Issues, Hydropower and Ecology of the Academy of Sciences of the RTj |
