Problem solved through this practice | Land salination represents the main challenge in the area due to improper irrigation technology and lack of drainage, in their turn leading to extremely low productivity. With time, the existing irrigation management system resulted in irrational use of water and land. While water distribution rates were calculated in a centralized manner depending on specific crops, in practice water supply monitoring is extremely poor – water supply (canals) infrastructure is inconsistent with farmers’ needs leading to excessive and, vice versa, insufficient watering of different sites. In addition, there exists an informal water payment system leading to the advantageous position of certain users. |

Tools used in the practice | Set of hydro-reclamation measures: preventive land forming (leveling), composting, monitoring of ground water bedding and mineralization, decentralized water management planning, capacity building, etc. |

Description of the practice and its results | Actions: A series of measures were executed to prevent land degradation and improve land reclamation condition, including introduction of high-performance drainage systems and reclamation technologies, construction of a new collector and cleaning of the existing one, construction of 9 water-regulating and 2 water-measuring facilities.

В 1980 году специалисты Научно-производственного объединения Среднеазиатского научно-исследовательского института ирригации (НПО САНИИРИ) разработали и впервые применили этот тип дренажа в Каршинской степи, где он показал свою эффективность. Из-за приостановки финансирования комбинированный дренаж не получил развития. Повторная практика использования комбинированного дренажа в Кувинском районе (2010) подтвердила его высокую эффективность и рентабельность, особенно в зонах с напорными подземными водами. Далее этот инструмент был использован в Риштанском, Алтыарикском и Багдадском районах, где он успешно работает. Мероприятия:

Lessons learnt and recommendations made | Lessons learnt:
Recommendations: It is necessary to focus on strengthening the role of local associations in rendering irrigation services and managing the canal’s water level. Local water users will be rendered an opportunity to design effective irrigation water management schemes. The experience of decentralized water planning and management accumulated by water tenants will be documented and distributed as a part of knowledge-management (capacity-building) strategy. It is necessary to closely cooperate with the newly established Agriculture Advisory Service working on sustainable land and water management, as well as to disseminate corresponding practices in other areas. |
Уроки: Практика подтвердила высокую эффективность и рентабельность комбинированного типа дренажа, особенно в зонах с напорными подземными водами. Рекомендации: Там, где позволяют гидрогеологические условия, необходимо широко использовать комбинированный тип дренажа. |
