Need to enhance water use planning and water consumption calculation techniques for agricultural crops with the account of climatic conditions and crop development phases based on decade water use planning hydro-modules proceeding from precipitation availability.

Increasing secondary land salination, deterioration of col-lector and drainage system (CDS)

CROPWAT 8.0 Software

A set of measures to enhance land reclamation condition (collector cleaning using special equipment, reconstruction of hydraulic engineering installations, etc.)

Actions:

• Analysis of existing methods of water resources use planning in dekhan farms of the Gissar Valley;
• Designing a water use planning technique with the account of irrigation patterns in dekhan farms.

Results:

Financial and economic:

effective use of irrigation water; reduced water consumption per harvest unit.

Ecological:

improved ecological and reclamation condition of irrigated land.

Technical:

executed decade hydro-modules based on precipitation availability allowing dekhan farms to plan their water consumption and draw up crop irrigation schedules depending on expected weather conditions in the Gissar Valley as well as to coordinate other technological and weather-dependent processes associated with crops cultivation.

Social:

prevention of conflicts, controversies and misunderstanding among water users related to irrigation water distribution.

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

Lessons learnt:

CROPWAT 8.0 Software allows enhancing the technology of water use planning via specification of irrigation modes depending on expected precipitation availability.

Recommendations:

It is necessary to widely apply CROPWAT 8.0 Software.

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
