Проблема, которая решается применением практики |
Uneven distribution of irrigation water, lack of water accounting means to ensure observance of recommended irrigation norms for cotton |
Increasing secondary land salination, deterioration of col-lector and drainage system (CDS) |
Примененные в практике инструменты |
Tubular water outlet flowmeter |
A set of measures to enhance land reclamation condition (collector cleaning using special equipment, reconstruction of hydraulic engineering installations, etc.) |
Описание практики и ее результаты |
Actions:
- Construction of tubular water outlet flowmeter with removable nozzles (procurement of polyethylene piping to make tubular water outlets and matching nozzles); - Installation of tubular water outlet flowmeter along temporary sprinklers.
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. |
Actions: The capital repair of inter-farm West Karmakshi Collector (WKC) is necessitated by the fact that in its current condition the Collector didn't provide for timely drainage of drainages and discharge water from cropland in the Left-Bank Massif.
Results:
Financial and economic: Increased crop productivity, mainly rice and forage crops
Technical: Enhanced reclamation condition of land in the Left-Bank Massif |
Какие уроки и рекомендации можно извлечь из практики |
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. |
Lessons learnt: Allocation of resources for cleaning CDS proved more efficient than other target actions
Recommendations: Regular and timely execution of running and capital collector cleaning is necessary to ensure its proper operation |
