上海市农科院牵头研制的稻田甲烷减排方法学被联合国机构采纳

Core Viewpoint - The "Methane Emission Reduction Methodology for Rice Fields," developed by the Shanghai Academy of Agricultural Sciences, has been officially adopted as the 103rd small-scale emission reduction methodology under the Clean Development Mechanism (CDM) of the United Nations Framework Convention on Climate Change, marking a significant achievement in agricultural greenhouse gas reduction research in China [1][2]. Group 1: Methodology Development - The methodology is China's first independently developed CDM methodology for methane reduction in rice fields, showcasing the country's leading position in this research area and its ability to establish core international rules and standards [1]. - The Shanghai Low Carbon Agricultural Engineering Technology Research Center has been conducting long-term monitoring of greenhouse gas emissions and soil carbon sinks in rice fields since 2012, accumulating hundreds of thousands of observation data points [2]. Group 2: Technological Innovations - The research team has developed various low-carbon agricultural technologies, including high-yield low-emission rice varieties, optimized water management, precise fertilizer application, comprehensive straw utilization, and innovative crop rotation models [2]. - A specific technology utilizing drought-resistant rice varieties has been developed, which effectively reduces methane emissions while maintaining stable yields, making it replicable and easy to promote [3]. Group 3: Global Implications - The adoption of this methodology provides a feasible and operational path for methane reduction, particularly for developing countries facing food security, emission reduction pressures, and water resource shortages [3]. - The certified emission reductions (CERs) generated from projects developed under this methodology are expected to enter broader international carbon trading markets, creating economic incentives for low-carbon rice production and attracting global investment towards sustainable agricultural practices [3].
