Transformation for sustainable nutrient supply and management

“向可持续营养供应和管理转型”（trans4num）项目旨在为欧洲和中国的可持续农业提供基于自然的解决方案（NBS）创新。特别是，trans4num将专注于养分管理（基于生物的养分来源、可持续的作物轮作、养分流动的优化），并将1)对NBS在实现可持续农业实践方面的潜力进行差异化理解，2)研究应用NBS的复杂性，3)开发动态和智能的养分管理工具，以支持最佳养分供应的区域决策。4)评估技术和社会创新以及与国家统计局相关的政策的（净）影响。为了实现其目标，trans4num将使用一个社会生态转型（SET）框架，专门研究国家统计局在7个集约化农业系统地区的20项农场级创新。该项目将实施多主体方法，考虑与农业营养管理中NBS相关的各种社会关切和利益，并确定有希望的社会创新转型途径，有助于更广泛地接受和采用NBS。在四年的时间里，该项目将汇集来自欧洲和中国22个合作伙伴在不同领域、技术和学科方面的经验、专业知识和知识，并应用一系列方法和形式来推进和促进NBS的实施前景（如农民讨论小组、利益相关者小组、黑客马拉松）。项目成果有望为“欧洲绿色协议”、“从农场到餐桌”、零污染雄心战略以及中国的政策：绿色农业发展“十四五”规划战略，其目标是遏制污染和限制氮磷排放，这些都没有公开描述

The project “transformation for sustainable nutrient supply and management” (trans4num) aspires to substantiate and broadly promote Nature-based solution (NBS) innovations for sustainable agriculture in Europe and China. In particular, trans4num will focus on nutrient management (bio-based nutrient sources, sustainable crop rotations, optimization of nutrient flows) and will 1) develop a differentiated understanding of NBS potentials for achieving sustainable agricultural practices, 2) study the complexities of applying NBS, 3) develop a dynamic and smart nutrient management tool to support regional decision making for optimum nutrient supply, and 4) assess the (net) impact of technological and social innovations as well as policies related to NBS. To realize its objectives, trans4num will use a socialecological transformation (SET) framework tailored to study 20 NBS farm-level innovations in 7 regions with intensive farming systems. The project will implement the multi-actor approach to consider various societal concerns and interests related to NBS in agricultural nutrient management and to identify promising transformation pathways for social innovations conducive to a wider acceptance and adoption of NBS . In the course of four years, the project will bring together experience, expertise and knowledge across different fields, technologies and disciplines from 22 partners in Europe and China and apply a range of methods and formats to advance and foster NBS implementation prospects (e.g. farmer discussion groups, stakeholder panels, hackathons) The results of the project are expected to contribute to the European Green Deal, Farm to Fork, and Zero Pollution ambition strategies as well as China’s policy: the 14th FiveYear Planning for Green Agriculture Development strategy with their ambition to halt pollution and limit N/P emissionsno public description
