The envisaged project aims at improving Greenhouse Gas Assessments in Rice Production Systems of SE Asia derived from results obtained in the recently completed DFG research group ICON (Introducing Non-Flooded Crops in Rice-Dominated Landscapes: Impact on Carbon, Nitrogen and Water Cycles, FOR 1701). In spite of ample evidence of technical feasibility of low-emission rice cultivation, these practices have so far not been adopted at wider scale, which is primarily due to an information deficit about their reduction potential with constant or increasing rice yields. This technology transfer will establish a comprehensive and fully functional framework of Greenhouse Gas (GHG) calculations consisting of GIS-data repositories and user-friendly software (collectively called ‘Digital Platform’). This Platform will be exemplified for Vietnam, a major rice-exporting country that is challenged by increasing demand for documenting sustainable production practices in exported food. The Platform will support all, the currently applied Tier 1/ Tier 2 approaches based on emission factors as well as Tier 3 which encompasses a process-based simulation model, namely LandscapeDNDC developed and validated in the ICON project. The overall objectives are to a) integrate the process-based LandscapeDNDC model simulating plant growth and GHG emissions from rice in a custom-made user friendly software, b) compile relevant data bases and explanatory documents and by this c) allow potential users to quantify GHG emissions from rice by various modeling approaches (Tier 1 to Tier 3), d) illustrate the potential of the Platform for MRV (Measurement, Reporting, Verification) and mitigation planning and e) substantiate planning decisions for GHG mitigation within the context of individual mitigation proposals and projects. The Platform will be developed in an iterative approach to obtain feedback from Vietnamese partners on the functionality of the Platform from their perspective. At the same time, the project partners will engage in intensive training and outreach to other stakeholders in Vietnam and beyond. Apart from documenting the GHG footprint of traded rice, the Platform is also geared toward supporting climate policies in Vietnam and other rice growing countries under the Paris Agreement. Given the significance of rice in the national GHG budget, the Vietnamese mitigation target committed in the Nationally Determined Contributions will rely on the inclusion of this production system as an essential component of the Nationally Determined Contribution -- and thus on accurate quantification of GHG emissions for different scenarios and scales.

设想中的项目旨在改进东南亚水稻生产系统的温室气体评估，该评估来自最近完成的DFG研究小组ICON（在水稻主导的景观中引入非淹水作物：对碳、氮和水循环的影响，FOR 1701）的结果。尽管有充分的证据表明低排放水稻种植在技术上是可行的，但这些做法迄今尚未得到更广泛的采用，这主要是由于缺乏关于它们在水稻产量保持不变或不断增加的情况下减少排放潜力的信息。这项技术转让将建立一个全面和功能齐全的温室气体（GHG）计算框架，包括地理信息系统数据库和用户友好软件（统称为“数字平台”）。该平台将以越南为例，越南是一个主要的大米出口国，面临着记录出口粮食可持续生产做法的需求日益增加的挑战。该平台将支持所有目前应用的基于排放因子的Tier 1/ Tier 2方法，以及Tier 3方法，其中包括基于过程的模拟模型，即在ICON项目中开发和验证的landscape ndc。总体目标是：a)在定制的用户友好型软件中集成基于过程的模拟植物生长和水稻温室气体排放的landscape ndc模型；b)编译相关数据库和解释性文件；c)允许潜在用户通过各种建模方法（第1层到第3层）量化水稻温室气体排放；d)说明MRV平台的潜力(测量，报告，核查)和缓解规划，以及e)在个别缓解建议和项目的范围内充实温室气体缓解的规划决定。该平台将以迭代的方式发展，以便从越南伙伴的角度获得关于平台功能的反馈。与此同时，项目合作伙伴将对越南及其他地区的其他利益相关者进行强化培训和外联。除了记录大米交易的温室气体足迹外，该平台还旨在支持越南和其他《巴黎协定》下的大米种植国的气候政策。鉴于大米在国家温室气体预算中的重要性，越南在国家自主贡献中承诺的减排目标将依赖于将这一生产系统作为国家自主贡献的一个重要组成部分，从而依赖于对不同情景和规模的温室气体排放进行准确量化。
