Water deficit; settlements and agricultural land under flood and mudflow threat during mudflow risk periods

Deterioration of reclamation situation: rising of ground water, land salination

Cascading storage pools (reservoirs) accumulating rain and runoff water

Technique and technology of land reclamation via a system of vertical drainage wells (VDW)

Actions:

• assessment of mudflow and flood risks and surveying local population regarding reservoirs’ locations and water uses (drinking and irrigation water supply);
• designing reservoirs;
• construction of reservoirs with the engagement of local residents;
• training of local residents on servicing reservoirs and corresponding equipment.

Results:

• reduced risks for public life and health;
• enhanced water supply of irrigated land;
• reduced risk of agricultural losses due to drought;
• reduced risk of biodiversity damage caused by mudflows and floods;
• enhanced public access to drinking water.

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.

• Cascading reservoirs provide better cumulative effect at lower cost compared to separate reservoirs;
• Application of modern water-proofing materials during the construction of storage pools (reservoirs) allows to reliably store winter and spring runoff to be used during vegetation period.

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.
