Problem solved through this practice |
Deterioration of reclamation situation: rising of ground water, land salination |
Increasing secondary land salination, deterioration of col-lector and drainage system (CDS) |
Tools used in the practice |
Technique and technology of land reclamation via a system of vertical drainage wells (VDW) |
A set of measures to enhance land reclamation condition (collector cleaning using special equipment, reconstruction of hydraulic engineering installations, etc.) |
Description of the practice and its results |
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.
However, currently due to the absence of a single organization responsible for VDW operation, maintenance and repair, the VDW systems recon-structed under World Bank and Asian Development Bank projects do not perform as effectively as ini-tially.
Results:
Financial and economic: Increased cotton yields (from 10-15 up to 30-35 dt/ha).
Technical: Successful response to land salination in 3 districts: ground water table steadily kept at 2-3 m depth leading to a sharp contraction of salinized land area. |
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 and recommendations made |
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; 2. Build personnel capacity: • Continual training of personnel in the Department and Provincial Hydrogeological and Land Reclamation Expedition; • Drafting and distribution of training materi-als. |
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 |
