CONTEXT

Food systems worldwide are under enormous pressure. Over the past decades, local food systems have been promoted by governments and civil society organisations as a lever for change towards more inclusive, resilient and sustainable food systems based on the belief of their many purported benefits.

OBJECTIVE

The goal of this article is to test eight common beliefs on local food systems – from a consumer, farmer, community and environmental perspective – against scientific evidence, with a focus on North America and Europe.

METHODS

We conduct a systematic multi-disciplinary literature review and identify 123 peer-reviewed studies on local food systems.

RESULTS AND CONCLUSIONS

We find that the impact of local food systems on different social, economic and environmental factors highly depends on the type of supply chain under assessment, with important differences across product types and countries. Hence, our review refutes the idea that local food is inherently good. In addition, we highlight the confusion surrounding the definition of a local food scale and point out a critical lack of cross-country comparable data hindering the possibility of drawing generalisable conclusions on the benefits and drawbacks of local food systems.

SIGNIFICANCE

A comprehensive review of multi-disciplinary scientific evidence confirming (or refuting) claims on local food systems was missing, leading to possible counter-productive policies. Based on our findings, we suggest that policy-makers should invest in cross-country comparable data collection on local food systems (especially in Europe), which would allow the scientific community to perform robust causal analyses on their impacts on society.

地方粮食系统:回顾二十年的研究

语境

全世界的粮食系统都承受着巨大的压力。在过去的几十年里,政府和民间社会组织一直在推动地方粮食系统,作为向更具包容性、弹性和可持续的粮食系统转变的杠杆,基于对它们的许多所谓好处的信念。

客观的

本文的目标是根据科学证据,以北美和欧洲为重点,从消费者、农民、社区和环境的角度,测试对当地食物系统的八种普遍看法。

方法

我们进行了系统的多学科文献审查,并确定了 123 项关于当地粮食系统的同行评审研究。

结果和结论

我们发现当地粮食系统对不同社会、经济和环境因素的影响在很大程度上取决于所评估的供应链类型,产品类型和国家之间存在重大差异。因此,我们的评论驳斥了当地食物本来就很好的观点。此外,我们强调了围绕当地食品规模定义的混乱,并指出严重缺乏跨国可比数据阻碍了对当地食品系统的利弊得出普遍结论的可能性。

意义

缺少对证实(或反驳)当地粮食系统声称的多学科科学证据的全面审查,导致可能产生适得其反的政策。根据我们的研究结果,我们建议政策制定者应该投资于当地粮食系统(尤其是欧洲)的跨国可比数据收集,这将使科学界能够对其对社会的影响进行强有力的因果分析。
