Optimizing irrigation water usage is crucial for sustainable agriculture, especially in the context of increasing water scarcity and climate variability. Accurate estimation of evapotranspiration (ET), a key component in determining water requirements for crops, is essential for effective irrigation management. Traditional methods of measuring and estimating ET, such as eddy-covariance systems and lysimeters, provide valuable data but often face limitations in scalability, cost, and complexity.  \nRecent advancements in machine learning (ML) offer promising alternatives to enhance the precision and efficiency of ET estimation and smart irrigation systems. This review explores the integration of machine learning techniques in optimizing irrigation water usage, with a particular focus on ET prediction and smart irrigation technologies. We examine various ML models, that have been employed to predict ET using diverse datasets comprising meteorological, soil, and remote sensing data. In addition to ET estimation, the review highlights smart irrigation systems that optimize irrigation schedules based on real-time data inputs. Through this review, we aim to provide a comprehensive overview of the state-of-the-art in MLbased ET estimation and smart irrigation technologies, contributing to the development of more resilient and efficient agricultural water management  \nstrategies.  \n1 Introduction  \nWater plays a vital role in irrigation and agriculture worldwide. The Food and Agriculture Organization of the United Nations (FAO) reported in 2017 that 70% of freshwater withdrawn globally is used in agriculture to sustain the growing human population [1] . Future projections indicate that water demand for irrigated food production will double by 2050, increasing pressure on already limited freshwater supplies. Although the FAO anticipates only a 10% increase in agricultural water withdrawal by 2050 due to improved management  \nΎ Corresponding author: [zaid.belarbi@etu.uae.ac.ma](zaid.belarbi@etu.uae.ac.ma)  \n© The Authors, published by EDP Sciences.

AI technologies are being leveraged to address the pressing challenges of modern agriculture, such as resource optimization, yield improvement, and sustainability. According to [3], AI in agriculture can be broadly divided into four categories: water management, soil management, livestock management, and crop management (Fig. 1) .  \nSoil management focuses on maintaining soil health and fertility. AI techniques are used to analyze soil properties, monitor nutrient levels, and provide precise recommendations for soil amendments, leading to improved crop yields and soil conservation.  \nLivestock management includes monitoring the health and productivity of animals using AIdriven tools. Sensors and machine learning algorithms track animal behavior, detect diseases early, and optimize feeding strategies, contributing to better livestock welfare and productivity.  \nCrop management encompasses a range of activities from sowing to harvesting, aimed at maximizing crop yields and quality. AI applications in crop management include disease detection, yield prediction, and precision farming techniques that optimize planting and
