Core Viewpoint - The implementation of the "One Field One Code" pilot program in Nanjing aims to enhance farmland protection and food security through digital identification and advanced monitoring technologies like drones and satellite data [1][6]. Group 1: Pilot Program Implementation - Nanjing has initiated the "One Field One Code" pilot program, which assigns a digital identity to farmland, integrating satellite, drone, and big data technologies for better management [1][6]. - The pilot program includes three districts: Qiqiao, Yongning, and Longpao, covering a total of 12.2 million mu of farmland [3][6]. - The program aims to establish a dynamic monitoring system and a closed-loop disposal mechanism to quickly identify and address issues related to farmland management [2][5]. Group 2: Technological Integration - Drones are a key component of the monitoring system, capable of flying up to 10 kilometers and providing high-resolution images for real-time analysis of farmland conditions [2][7]. - The system will utilize a combination of high-definition imagery, drone assistance, and manual verification to ensure accurate monitoring of farmland [2][5]. - A digital management system will be optimized to provide comprehensive data integration and monitoring services for various departments involved in farmland management [6][7]. Group 3: Data Collection and Management - The pilot program emphasizes the importance of thorough data collection to create a unified account of farmland usage and conditions [3][5]. - A QR code system will be implemented to allow easy access to information about specific plots of land, ensuring transparency and efficiency in management [6][7]. - The program aims to complete the initial data collection phase by the end of May, followed by data integration and information storage [6][7]. Group 4: Future Plans and Expansion - The pilot program is expected to be completed by August, with plans to expand the initiative to all agricultural sectors in the city by the end of the year [7]. - Collaboration among planning, agricultural, and forestry departments will be strengthened to ensure effective monitoring and management of farmland [7].
