Smart Water Management on Quality Crop Production

Climate change influences agriculture and agriculture-based livelihoods both directly and indirectly. Agriculture is the biggest consumer of freshwater in the world, amounting to up to 70% of the total use, which makes the case for smart water management in order to guarantee water and food security to the world?s population. In recent decades, research on precision irrigation driven by climate change has developed a multitude of strategies, methods and technologies to reduce water consumption in irrigation projects and to adapt to the increasing occurrence of water scarcity, agricultural droughts and competition between agricultural and industrial sectors for the use of water. In this context, the adoption of water-saving and application practices implies a multidisciplinary approach to accurately quantify the water needs of crops under different water availability and management practices. The intelligent irrigation technique is a valuable tool for monitoring and quantifying irrigation water added for plants as well as for irrigation scheduling. Thus, this review article presented a review of technologies and new trends in the context of precision irrigation, future perspectives and critically analyze notions and means to maintain high levels of land and water productivity, which minimize irrational water consumption at the field level.
