The aim of this paper is the creation of an integrated and free-access web platform for parcel irrigation water management on a large spatial scale (Water District of Crete, in Greece) in order to: a) accurately determine the irrigation needs of the main crops for Crete such as olives, citrus, avocados and vineyards, b) design strategies, for optimal adaptation of the agricultural sector in the context of climate change, and c) incorporate the dynamic integration of the above information through the creation of a digital platform. In the proposed decision-making system, essential factors are taken into account, such as real-time meteorological data, information about the type and spatial distribution of the agricultural parcels in Crete, algorithms for calculation crop evapotranspiration per development stage and age of the crops, satellite remote sensing techniques in combination with field surveys to depict accurate soil texture map for the whole island of Crete as well as sustainable cultivation practices for saving water per crop and parcel geomorphology. Based on the proposed decision-making system, users will have the opportunity in any specific location/farm in Crete to know the irrigation needs of the crops in real-time and obtain information about proper climate-water adaptation practices. The main novelty points of the proposed platform include the derivation of parcel-level soil texture data from Sentinel-2 satellite imagery and field samples, the comprehensiveness of the irrigation management information, the relatively low data requirements and the application interface simplicity provided to the end-user.
本文的目的是创建一个集成的、免费访问的大型空间尺度（希腊克里特岛水行政区）包裹灌溉水资源管理的网络平台，以便：a）准确确定克里特岛主要作物（如橄榄、柑橘、鳄梨和葡萄园）的灌溉需求，b）设计战略，以实现农业部门在气候变化背景下的最佳适应，c）通过创建数字平台实现上述信息的动态集成。在所提出的决策系统中，考虑了实时气象数据、克里特岛农业地块的类型和空间分布信息、每个发育阶段和作物年龄的作物蒸发蒸腾量计算算法、卫星遥感技术与实地调查相结合，以描绘克里特岛全岛精确的土壤质地图，以及每一种作物和地块地貌的节水可持续种植实践等基本因素。基于所提出的决策系统，用户将有机会在克里特岛的任何特定位置/农场实时了解作物的灌溉需求，并获得有关适当气候-水资源适应实践的信息。拟议平台的主要新颖之处包括从 Sentinel-2 卫星图像和实地样本中推导出地块级土壤质地数据、灌溉管理信息的全面性、相对较低的数据要求以及为最终用户提供的应用程序接口简单性。
