**7. Conclusion**

Smart irrigation has gained significant attention as the need to improve water use efficiency increases. Smart irrigation involves data acquisition, interpretation, analysis, and control. Monitoring and control require sensors to collect real-time information for irrigation scheduling decisions. An irrigation control strategy has to be adopted for irrigation decisions. Closed-loop irrigation strategies with feedback from sensors are widely used for real-time irrigation decisions. Smart irrigation can save irrigation water and improve yield at the farm level, consequently leading to improved food security for the global population. In all the irrigation systems, it is possible to implement smart strategies that can help in saving irrigation water and improve yields.
