辽宁：“以电折水”促农业灌溉节水增效

Core Insights - The project "Electricity to Water" has been recognized as a typical case for data circulation safety governance by the National Data Bureau, highlighting its significance in agricultural water management [1] - Liaoning province has completed the registration of nearly 60,000 agricultural irrigation wells, which aids in establishing a water measurement system based on electricity consumption [1] Group 1 - The "Electricity to Water" method estimates water usage based on electricity consumption, addressing the challenge of water resource management in a province with significant agricultural water needs and severe water scarcity [1] - Liaoning province has become one of the first pilot provinces for the "Electricity to Water" initiative, collaborating closely between water and electricity departments to assess water usage accurately [1][2] - The province has constructed 2,639 sample wells since 2022, enabling online measurement of water extraction and allowing for cost-effective management of water resources [2] Group 2 - The use of sample wells allows for the estimation of water usage across various irrigation wells without the need for extensive infrastructure, thus reducing construction and maintenance costs [2] - A data sharing and exchange mechanism has been established between water and electricity departments, facilitating cross-industry data utilization for better water management [2] - Future applications of this data include optimizing irrigation water sources and network layouts, particularly in projects like converting dry fields to irrigated fields and designing irrigation networks [2]
