Abstract Local Food Systems (LFS) are a relatively new concept in planning. While there is a growing interest in making transformative change in LFS, the area lacks a solid theoretical foundation to address how change processes in food systems occur. In this study, a classic Glaserian grounded theory methodology was used to investigate LFS planning. The primary goal was the development of theory grounded in the experience of practitioners, elected officials, and members of the public all having some level of experience with LFS initiatives. The data are drawn from interviews with 29 elected officials, public stakeholders, and planning staff working in five communities with LFS planning initiatives. In addition, 10 member checking interviews were conducted to determine the fit and relevance of the findings to the experience of participants in LFS planning. The emergent theory of ‘Transformative Incrementalism’ (TI), was developed from this research to describe the social processes underlying planning initiatives to achieve transformative change in LFS. Consistent with grounded theory principles, the core category identified in the theory was Power, while Values, Praxis, and Outcomes were other main themes. TI suggests that change is achieved through a long process of incremental efforts by actors within the public, political, and bureaucratic groups to achieve convergence and align values and beliefs over time.

变革渐进主义：规划当地粮食系统的变革

摘要 本地食品系统 (LFS) 是一个相对较新的规划概念。虽然人们对 LFS 的变革性变化越来越感兴趣，但该领域缺乏坚实的理论基础来解决粮食系统中的变化过程如何发生。在这项研究中，使用经典的 Glaserian 扎根理论方法来研究 LFS 规划。主要目标是发展以实践者、民选官员和公众成员的经验为基础的理论，他们都对 LFS 计划有一定程度的经验。数据来自对 29 位民选官员、公共利益相关者和在五个社区开展 LFS 规划举措的规划人员的访谈。此外，进行了 10 次成员检查访谈，以确定调查结果与 LFS 计划参与者的经验的契合度和相关性。“变革性增量主义”（TI）的新兴理论是从这项研究中发展起来的，以描述实现 LFS 变革性变化的规划举措背后的社会过程。与扎根理论原则一致，理论中确定的核心类别是权力，而价值观、实践和结果是其他主要主题。TI 建议，变革是通过公众、政治和官僚团体中的行为者的长期渐进努力来实现的，目的是随着时间的推移实现融合和统一价值观和信仰。是从这项研究中发展起来的，以描述实现 LFS 变革的规划举措背后的社会过程。与扎根理论原则一致，理论中确定的核心类别是权力，而价值观、实践和结果是其他主要主题。TI 建议，变革是通过公众、政治和官僚团体中的行为者的长期渐进努力来实现的，目的是随着时间的推移实现融合和统一价值观和信仰。是从这项研究中发展起来的，以描述规划举措背后的社会过程，以实现 LFS 的变革。与扎根理论原则一致，理论中确定的核心类别是权力，而价值观、实践和结果是其他主要主题。TI 建议，变革是通过公众、政治和官僚团体中的行为者的长期渐进努力来实现的，目的是随着时间的推移实现融合和统一价值观和信仰。
