Water-scarce areas are threatened by climate crisis and, thus, there is an urgent need for optimizing water resources management. Remote sensing has been widely used for calculating the evapotranspiration over large areas, which is an essential variable for calculating the actual irrigation needs of crops. The main objective of this work is to design an approach to optimize the irrigation needs for specific crops. The island of Cyprus is used as a case study providing first insights for water management in the country. The proposed approach is crucial to the agricultural industry of Cyprus since it is located in the Mediterranean region which is affected by warm climate and drought events. Specifically, the proposed approach calculates daily the crop evapotranspiration over the island for three of the most important crops (i.e., citrus, olives, and potatoes) cultivated in Cyprus. The results of this study are showing that the three crop types are withdrawing much more water than the total annual inflow of reservoirs in 2023. Therefore, better irrigation management needs to be adopted by farmers while optimized water resources management practices have to be embraced by local authorities and stakeholders.
水资源匮乏地区受到气候危机的威胁，因此，迫切需要优化水资源管理。遥感技术已被广泛用于计算大面积的蒸散量，而蒸散量是计算作物实际灌溉需求的一个重要变量。这项工作的主要目标是设计一种方法来优化特定作物的灌溉需求。塞浦路斯岛被用作案例研究，为该国的水资源管理提供了初步见解。由于塞浦路斯位于受温暖气候和干旱事件影响的地中海地区，所提出的方法对塞浦路斯的农业产业至关重要。具体而言，所提出的方法每天计算塞浦路斯种植的三种最重要作物（即柑橘、橄榄和土豆）在全岛的作物蒸散量。这项研究的结果表明，这三种作物类型在2023年抽取的水量远远超过水库的年总入水量。因此，农民需要采用更好的灌溉管理方式，而地方当局和利益相关者必须采用优化的水资源管理做法。
