Adopting deficit irrigation and enhanced farm irrigation systems can reduce demand. A better level of irrigation uniformity is closely correlated with the improvement of irrigation systems. Better design, attentive maintenance, suitableirrigationequipmentselection,andincreasedfield evaluation are all implied by this. Improved homogeneity createstheopportunitytouselow-qualitywaterswithless environmentalimpactandtoachievehigherefficiency.The reviewhasdemonstratedthatbecauseawiderangeoffactors affect irrigation performance, the economic effects of upgradingirrigationarenotwellunderstood.
Generally speaking, the most limited resource in places of water shortage is water rather than land. In these circumstances, maximizing the return per unit of water rather than the return per unit of land can be more advantageous. This appears to be the case for the supplemental watering of cereals, but other important considerationsshouldalsobemade,suchastheamountof fertilizerappliedandthetimingofsowing.However,when supplementalirrigationistakenintoaccount,thequantityof rainfall that is available has a significant impact on the economic outcomes at the farm level. The review also demonstrates that, in typical climates, deficit irrigation of certain crops may be possible, but not in drought-prone areas,asdemonstratedbythepotatocropasanexample.In places where water is scarce, irrigation schedules that maximize water production and farm profitability must followcertainprinciples.
Itisanticipatedthatintheupcomingdecades,theprimary goalofirrigationwillchangefromthephysiologicalgoalof increasingcropyieldsperunitoflandtoaneweconomicgoal of maximizing net returns to irrigation [11]. This could be called,toputitsimply,an"optimization"paradigm.Lower irrigationdepthsandloweryieldsperunitofirrigatedland are typically associated with optimization. However, farm profitability will rise as running costs are decreased and waterisfreedupforotherfruitfuluses.Whenreturnflows from irrigation would otherwise be irretrievably lost, additional water may become available to other off-farm purposes.
Optimal management practices should still be expected to benefit farmers and other water users through lower production costs, better water distribution, and less environmentalimpact,evenincaseswhereirrigationreturn flows are nearly totally recovered. A broader definition of optimal irrigation from a social standpoint would be the maximization of all benefits, which would include nonfinancialadvantagessuchthepreservationofwaterquality, food security, job growth, and population relocation. The optimizationmethodwillbemoredifficultthanthecurrent standard irrigation practices. Crop-water production functionsandspecificcostfunctionsthatarenownottaken intoaccountinirrigationplanningorschedulingwillneedto

Analysts will typically have to handle a variety of goals and a broad range of potential approaches.Theymayalsoneedtotakeuncertaintyandthe potential for increased financial risk into account.

In concluding our comprehensive review of various methodologies for irrigation optimization in agriculture, it becomes evident that the field is teeming with diverse approaches,eachcontributinguniquelytotheoverarching goalofresource-efficientandsustainablewatermanagement. Aswereflectontheextensivebodyofworkexploredinthis paper, a notable observation emerges the conspicuous absence of non-IoT methodologies, particularly those that leverageMachineLearning(ML)withoutdirectrelianceon sensors.

Notably,MLalgorithmsthatoperateindependentlyofsensor input present an intriguing avenue for exploration. These methodologies, which often draw from historical data, climaticpatterns,andsoilcharacteristics,offerapragmatic alternative, particularly in scenarios where sensor deploymentmightbeeconomicallyorlogisticallychallenging.
