Strategies (measures) Of Water Conservation

 The following strategies (measures) can be adopted for conservation of water.

1. Reducing Evaporation losses :

Evaporation of water in humid region can be reduced by placing horizontal barriers of asphalt below the soil surface, which increases the water availability and crop yield. 

2. Reducing  Irrigation Losses :

The water losses during irrigation can be reduced by the following methods. 

1. Sprinkling irrigation and drip irrigation conserves water by 30-40% 

2. Growing Hybrid crop varieties, which require less water, also conserve water.

3. Irrigation in early morning or later evening, reduces evaporation losses.

3. Re-Use of Water 

i) Treated Waste water can also be used for ferti-irrigation.

ii)Grey water, from washings, bath-rooms, etc., may be used for washing cars, watering Gardens.

4. Preventing wastage of water 

Wastage of water can be prevented by

i) Closing the taps when not in use. 

ii) Repairing any leakage from pipes.

iii) Using Small capacity of taps.

5. Decreasing run-off losses 

Run-off on most of the soils can be reduced by allowing most of the water to infiltrate into the soil, This can be done by using contour cultivation or terrace farming.  

6. Avoid Discharge of Sewage 

 The discharge of sewage into natural water resources should be prevented as much as possible.
