上海市农科院为全球贡献稻田甲烷减排“中国方案”

Core Insights - The methane reduction methodology for rice paddies developed by the Shanghai Academy of Agricultural Sciences has been adopted as the 103rd small-scale reduction methodology under the UN Framework Convention on Climate Change's Clean Development Mechanism (CDM) [1] - This methodology is China's first independently developed rice paddy methane reduction methodology with complete intellectual property rights and marks the second such methodology adopted by the CDM [1] - The establishment of this methodology signifies China's international leadership in agricultural greenhouse gas reduction methodologies and its capability to formulate core international rules and standards in this field [1] Summary by Sections Development and Research - Since 2012, the research team has established a long-term experimental base for low-carbon agriculture, conducting long-term monitoring of greenhouse gas emissions and soil carbon sinks under various rice cultivation management models, accumulating hundreds of thousands of data points [1] - The team has systematically developed low-carbon agricultural technologies, including high-yield low-water rice variety selection, optimized water management, precise fertilizer application, comprehensive straw utilization, and innovative crop rotation models [1] Methodology and Standards - The newly developed methodology includes technologies for methane reduction in rice paddies, nitrous oxide suppression in dryland, soil carbon sequestration in farmland, and straw carbonization for reduction and enhancement of carbon sinks [1] - The water-saving drought-resistant rice methane reduction technology is one of the key outcomes, effectively coupling water management and drought-resistant varieties to ensure stable yields while achieving significant methane reduction [2] Economic and Environmental Impact - The "Chinese solution" for rice paddy methane reduction aligns perfectly with the core concept of the Paris Agreement, which advocates for international cooperation to promote sustainable development and reduction benefits [2] - The certified emission reductions generated from projects developed based on this methodology are expected to enter the international carbon trading market, providing low-carbon technologies for rice producers and creating carbon revenue for project developers, thereby stimulating economic drivers for agricultural emissions reduction [2]
