More Yield with Less Water-Techniques to Achieve A Higher Efficiency in Irrigation
Dieter Prinz and A.H.Malik
Institute of Water Resources Management,Hydraulic and Rural Engineering,University of Karlsruhe,D-76128 Karlsruhe,Germany
1Introduction
In the Developing World,agriculture counts for about 80% of total water withdrawal（Prinz,2000）.Agriculture is under enormous pressure by the other sectors of the economy,as the economic value created per unit water is lowest in agriculture.At the same time,growing populations make it necessary to produce more food and fibre and to ensure that crop yields per unit land continue to rise.Therefore,developing countries will have to find ways of growing more food with less water.But there is not only the problem of water quantity but additionally the one of deteriorating quality of water.
There are many modern and traditional or combined technologies available to improve water conservation development（Agarwal,2001,Rijsberman,2001）.
There is the need①to define the aim（under given frame work conditions）；②to analyze the losses（conveyance,distribution,application a.o.losses）；③to identify the most promising water conservation methods and techniques,and,eventually；④to integrate the various elements within a（soil and）water conservation strategy（Emerson,1998,UNEP,1998）.
2Measures applied in irrigated agriculture
Irrigation water,if in ample supply,reduces considerable the risk of agricultural production and allows yields double as high as the yields which can be obtained from rain-fed agriculture（FAO,2001）.Roughly 40% of the food is produced on irrigated land,on 17% of the total cultivated land.The water needed for crops amounts to 1000～3000 m**er ton of cereal harvested.With other words,it takes one to three tones of water to grow 1kg of rice.
As mentioned before,the losses of water have to be covered as well as the measures to increase the efficiency of water use in irrigation.
We have to distinguish between recoverable water losses and unrecoverable water losses;the latter ones are those quantities of water lost to the atmosphere,to saline aquifers or to the sea.
Recoverable losses include:seepage,surface runoff,operational losses and losses due to deep percolation.
Fig.1Water losses within a surface irrigation system in a semi-arid region
The water losses could be（Fig.1）
conveyance losses.
distribution losses（e.g.canal evaporation,percolation and operation losses）or
field-ditch losses,
field-application losses which depend on soil,irrigation method and management,
Reduction of conveyance and distribution losses
33%～50% of water diverted for irrigation is lost‘en route’：The conveyance and distribution losses are enormous.By lining the canal system or by conveying the water in pipes,these losses can be significantly reduced.It should be kept in mind,that at least the seepage losses are in most cases recoverable losses;the water might be lifted up from the groundwater layer downstream.
Seepage losses occur in unlined main canals,in the canal distribution system and in field ditches.Most of the water is lost in unlined main canals.The questions which arise here are the following:
What quantities of water are lost?
Are these losses easy to recover?
What feasible lining methods could be used?
How high are the costs of lining and of maintenance?
What are the benefits of the saved water?
Could the unlined canal be used in the rainy season to recharge an aquifer?
Reduction of application losses
Application losses are either surface runoff losses or percolation losses,often summarised as“operational losses”.The water applied,should be sufficient to wet the volume of root penetration,but should not go beyond.Numerous technical means are available to apply exactly the amount of water needed,but financial and labour problems,in large irrigation schemes also management problems,hinder this.
Operational losses depend on：①the chosen distribution system；②the available regulating and mechanical facilities；③the skill and discipline of the operator.
3Crop root zone depth
The active root zone of the crop（if water is not a constraint）depends on：①crop type；②its stage of maturity；③soil conditions（Fig.2）.
Fig.2The water applied should be sufficient to wet the volume of root penetration（but not more）
Use of efficient irrigation methods
The large differences in water efficiency between the various irrigation methods are quite well known:Traditional surface irrigation generally achieves only around 40%efficiency,sprinkler irrigation can be 70%～80% efficient and drip irrigation might reach over 90% efficiency（Wolf and Stein,1998,Fig.3）.Modern irrigation technology could in theory save about half of the water presently consumed in irrigation,but technical,economic and socio-cultural factors hinder the transformation of theory into practice.
These methods are arranged according to their average efficiency.
The surface irrigation techniques are：①basin irrigatio。
