Проблема, которая решается применением практики | 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). |
Deterioration of reclamation situation: rising of ground water, land salination |
Примененные в практике инструменты | Method of autumn and winter water-charging irrigation |
Technique and technology of land reclamation via a system of vertical drainage wells (VDW) |
Описание практики и ее результаты | Actions: Results: Financial and economic: Technical: |
Actions: A VDW system set up. Prior to its installation, the area was drained via a horizontal open-type drain-age network ineffective as to reducing the mass of salinized land. Comprehensive VDW efforts significantly enhanced drainage.
Results: Financial and economic: Technical: |
Какие уроки и рекомендации можно извлечь из практики | 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: In due time, the model proved useful and timely, as the country urgently needed to increase its cotton yields. The practice demonstrated high efficiency of VDW in combatting land salination. Recommendations: 1. Establish a special VDW System Maintenance and Operation Department; |
Источник практики | Traditional tools transferred from generation to generation that proved their efficiency in modern conditions |
Domestic tools (outcomes of research by domestic R&D organizations) |
