I. Meticulous Planning: Consolidating Project Foundations and Pooling Wisdom from Multiple Parties
Before the official launch of the project, the Beijing International Institute of Ecological Economy, in collaboration with the Tianya District People's Government and other units, conducted nearly two years of preliminary research and scientific demonstration starting from 2021. Despite the impact of the epidemic, the project team overcame difficulties and organized academicians, experts, and dozens of units including research institutes, universities, and enterprises to conduct in-depth field investigations in Baoqian Village. They systematically analyzed the local agricultural structure, resource endowments, waste and carbon emission status, and planned green ecological low-carbon development paths.
During this period, the project team maintained close communication with the Tianya District Committee and District Government. The District Mayor personally took charge, listened to special reports on multiple occasions, and clearly identified zero-waste and zero-carbon ecological agriculture as an important starting point for regional green transformation. Through multiple seminars and expert demonstrations, the "Feasibility Study Report on the Zero-Waste and Zero-Carbon Ecological Agriculture Demonstration Zone Project in Tianya District, Sanya City" was finally formed. Meanwhile, on the basis of 摸清建设前废弃物及温室气体排放现状的基础上，明确了项目目标、技术路线与实施路径，为项目后续申报与落地奠定了坚实的基础。
II. Meticulous Organization: Strengthening Grassroots Mobilization and Building a Co-construction Mechanism
The most difficult aspect of the project was land acquisition and gaining the support of villagers. The Beijing International Institute of Ecological Economy stationed personnel in the village and district to provide assistance, visiting each household individually. The Tianya District Government quickly took the lead in establishing a project special team, launching grassroots mobilization and organizational coordination work. They conducted in-depth visits to 11 villager groups and over 100 households in Baoqian Village, promoting the concept of zero-carbon agriculture, explaining the project's significance and participation methods, and enhancing villagers' recognition and participation in ecological agriculture through village representative meetings, field seminars, and door-to-door services.
III. Meticulous Construction: Coordinating Project Implementation and Promoting Project Implementation
The project design unit, Shanghai Municipal Engineering Design Institute (Group) Co., Ltd., carried out meticulous design and proactive services. In terms of infrastructure construction, the project completed land consolidation, field division, organic fertilizer base application, and ridge arrangement in the natural farming area; constructed ecological chicken and duck sheds, feed warehouses, and other breeding facilities; implemented paddy field transformation projects, including water inlet and drainage systems, ditch excavation, and ridge reinforcement, laying the foundation for the integrated rice-fish-shrimp farming model.
The project actively introduced social capital and technical forces to promote the implementation of sub-projects such as "zero-carbon buildings, rice-shrimp engineering, and fulvic acid high-value organic fertilizer pepper projects." The Beijing International Institute of Ecological Economy assisted Academician Wang Fuming's team in achieving a bumper harvest in fulvic acid organic fertilizer pepper cultivation, driving local employment.
IV. Meticulous Services: Strengthening Scientific and Technological Support and Improving Project Quality
To ensure the scientific advancement of the project, the Beijing International Institute of Ecological Economy established an expert on-site service mechanism, inviting long-term resident experts in agriculture, ecology, carbon sink, and other fields to provide guidance, conduct soil testing, variety selection, and technical training. Systematic testing was conducted on different types of soils in Baoqian Village, including paddy fields, gardens, and woodlands, clarifying key indicators such as organic matter, total nitrogen, and available phosphorus, providing a basis for precise fertilization and soil improvement.
Currently, the project construction process has achieved carbon neutrality. According to the preliminary plan, the project adopted emission reduction measures such as energy-saving and low-carbon construction techniques and technologies, and the use of energy-efficient equipment to minimize greenhouse gas emissions during the construction process. It offset and neutralized the 218tCO2e greenhouse gas emissions generated during the construction period by canceling an equivalent amount of verified Voluntary Carbon Units (VCUs) from the international voluntary emission reduction mechanism project (VCS) (Project name: Inner Mongolia Sunjiaying 50.25MW Wind Power Project, Project No.: 395). This complies with the relevant requirements of ISO 14068-1:2023 Climate change management—Transition to net-zero Part 1: Carbon neutrality, and Fangyuan Mark Certification Group issued a carbon neutrality certificate for the construction period of the project.
In addition, the project team actively organized various science popularization and training activities. Relying on the under-construction Zero-Carbon Science Popularization Center, they conducted courses on dual-carbon knowledge popularization, ecological agriculture technology training, and farmer skill improvement, enhancing villagers' understanding and practical ability regarding carbon neutrality and ecological agriculture. Through activities such as the "Carbon Township" Practice Achievement Promotion Week, the project demonstrated its effectiveness and enhanced social influence.
V. Digital Empowerment: Building an Intelligent Zero-Carbon Agricultural Management System
To achieve refined operation and maintenance of the project and full-process management and control of carbon footprints, the project innovatively integrates a dual-carbon management platform with agricultural and forestry IoT technology, forming an integrated intelligent management system of "monitoring-analysis-regulation."
Dual-Carbon Intelligent Management Platform Construction. A comprehensive dual-carbon management platform covering the entire park was built, establishing a credible carbon asset ledger through blockchain technology to achieve precise tracking of key links such as biochar production, soil carbon sequestration, and forestry carbon sinks. The platform integrates carbon emission monitoring and carbon sink accounting functions, providing technical support for the value transformation of agricultural carbon sinks.
Agricultural and Forestry IoT Technology Application. An IoT monitoring network covering planting areas, breeding areas, and energy areas was deployed to collect real-time data on soil physical and chemical indicators, livestock and poultry growth status, and renewable energy generation efficiency, providing a data foundation for the precise management of ecological agriculture. An intelligent decision-making system was built based on IoT data to achieve automated control of functions such as water-fertilizer integrated precision irrigation, early warning of diseases and pests, and optimization of biochar production processes, significantly improving resource utilization efficiency and ecological benefits.
Technological Integration and Innovation Achievements. The deep integration of the dual-carbon platform and IoT technology has achieved full 资源化利用 of agricultural waste, constructed a sustainable development closed-loop of "ecological practice-carbon sink generation-value transformation," and formed a replicable smart zero-carbon agricultural solution. The innovative application of digital means has injected technological momentum into ecological agriculture and provided a demonstration practice for the coordinated advancement of rural revitalization and carbon neutrality goals.
