Ways to Improve Water Use Efficiency

Water Use Efficiency

• The ratio of water used in plant metabolism to water lost by the plant through transpiration.

• Two types of water use efficiency. Photosynthetic water-use efficiency • The ratio of the rate of carbon assimilation(photosynthesis) to

the rate of transpiration.

water-use efficiency of productivity • The ratio of biomass produced to the rate of transpiration

Ways to Improve Water Use Efficiency

1. Improve water use efficiency:-• Avoid over-irrigation by improving the farm irrigation system.• Implementing a drip irrigation system which enhances

irrigation efficiency.• land should be properly leveled in case of flood/furrow

irrigation.

2. Use Alternative sources of water:-• Use of rainwater collected from containers, roofs of farm

buildings.

3. Prevent and repair leaks:-• Prevention and repairing infield leaks can save water in the farm.• Use leak detectors as listening sticks, remote listening devices,

pressure fluctuation sensors, e.t.c.• Install drinking systems properly.

4. Schedule Irrigation:-• Take account of the evapotranspiration rate and soil moisture

deficits.• Climate conditions should be checked that the exact amount

crop water requirement per day.

5. Understand soil structure and manage moisture conditions:-• Understand how soil properties affect water storage• Soil moisture depends on climate, topography and other soil

characteristics.

6. Minimize land degradation:-• Reducing land degradation is important for increasing water

use efficiency.• No-tillage

7. Manage pesticides on a responsible way:-• The use of pesticides can result on water pollution if not managed on a

responsible way.• Assess the risk of pesticides use on water resources.• Water quality should be checked by PRiME (Pesticide Risk Mitigation

Engine).

8. Avoid water pollution:-• Agricultural processes such as tillage, ploughing of the land, use of

pesticides, fertilizers, over irrigation, spreading of slurries and manure can cause the contamination of water if not properly managed.

• The use of waste water can result in important health and environmental implications.

9. Use alternative washing and cleaning

processes:-• To diminish the water use in washing materials it is

recommendable. • Scrapers, squeegees and brushes can be used to remove solid

waste before cleaning them with water.• It can also reduce the risk of creating diffuse pollution.• In addition, farmers can use pressure washers to improve

efficiency of cleaning and reduce water use.

10. Establish a Water Management Plan:-• A good way of managing water use and water pollution is to

establish a comprehensive Water Management Plan (WMP) for the farm that identify water use and sources of pollution, water footprints of the crops, water efficiency plans within the farm.
