ABSTRACT Community gardens have been proposed as a way to build community capacity while simultaneously improving equity in food systems, core tenets of the food justice movement. Yet to date, there is no literature that connects the evidence-based outcomes of community gardening with specific social and dietary aspects of the movement. To explore this, we analysed 277 community gardening articles, which resulted in 31 quantitative, qualitative, or mixed methods studies that met the inclusion criteria for this synthesis. An appraisal of the quality of each included study was conducted. Results of the synthesis indicate many positive impacts across seven outcomes: three related to the social benefits of gardening (social capital, neighbourhood participation, community sharing) and four related to the dietary benefits of gardening (fruit and vegetable intake, food quality, food security, access to produce). Findings were similar across studies, although methodological rigour in study design and lack of participant racial/ethnic and socioeconomic diversity were common issues. Studies found that community garden participation is positively correlated with aspects of community connectedness but evidence demonstrating that it improves diet is neutral. Given these results, that community gardening may be an effective strategy to create a more equitable and just food system remains unclear.

对与食品正义相关的社区花园参与结果的系统、混合研究回顾

摘要 社区花园已被提议作为建设社区能力的一种方式，同时改善食品系统的公平性，这是食品正义运动的核心原则。然而，迄今为止，还没有文献将社区园艺的循证结果与该运动的特定社会和饮食方面联系起来。为了探索这一点，我们分析了 277 篇社区园艺文章，产生了 31 项定量、定性或混合方法研究，符合该综合的纳入标准。对每项纳入研究的质量进行了评估。综合结果表明，七项成果有许多积极影响：三项与园艺的社会效益有关（社会资本、邻里参与、社区共享）和四个与园艺的饮食益处有关（水果和蔬菜摄入量、食品质量、食品安全、农产品获取）。尽管研究设计的方法学严谨以及参与者缺乏种族/民族和社会经济多样性是常见问题，但不同研究的结果相似。研究发现，社区花园的参与与社区连通性的各个方面呈正相关，但表明它可以改善饮食的证据是中性的。鉴于这些结果，社区园艺可能是创造更公平和公正的食物系统的有效策略尚不清楚。尽管研究设计的方法学严谨以及参与者缺乏种族/民族和社会经济多样性是常见问题。研究发现，社区花园的参与与社区连通性的各个方面呈正相关，但表明它可以改善饮食的证据是中性的。鉴于这些结果，社区园艺可能是创造更公平和公正的食物系统的有效策略尚不清楚。尽管研究设计的方法学严谨以及参与者缺乏种族/民族和社会经济多样性是常见问题。研究发现，社区花园的参与与社区连通性的各个方面呈正相关，但表明它可以改善饮食的证据是中性的。鉴于这些结果，社区园艺可能是创造更公平和公正的食物系统的有效策略尚不清楚。
