Many people in high-income countries obtain considerable portions of their diets from gardening, hunting, fishing, foraging, and raising animals. Yet food security research in these countries has focused on the roles of commercial and charitable food systems, ignoring non-market food self-provisioning. This review brings together existing evidence to build a holistic understanding of how home and wild food procurement (HWFP) interacts with various dimensions of food security in high-income societies.
HWFP impacts food security in multiple ways. It can increase food availability, improve dietary quality, provide access to otherwise unaffordable foods, and support the stability of household food supplies through personal hardships and societal shocks, though further research is needed to substantiate when, where, and how these relationships hold. Engaging in HWFP provides people with agency over their food sources and can contribute to shrinking the ecological consequences of food sourcing. However, researchers have identified numerous food safety risks associated with HWFP, as well as ways in which these practices can threaten the sustainability of food systems. More research is needed regarding HWFP's potential to contribute to the overall food supplies of high-income countries, during crises as well as in periods of stability. HWFP clearly contributes to food security in high-income countries, but many of the concrete contours of this contribution remain to be revealed. Food security researchers should further account for the effects of HWFP, and scholars studying HWFP activities should consider food security as both a driver and potential consequence of engaging in these practices.
在高收入国家，许多人的饮食有相当一部分来自园艺、狩猎、捕鱼、觅食和饲养动物。然而，这些国家的粮食安全研究主要关注商业和慈善食品系统的作用，而忽视了非市场食品的自给自足。本综述综合现有证据，以全面了解家庭和野生食物获取（HWFP）如何与高收入社会粮食安全的各个维度相互作用。
HWFP以多种方式影响粮食安全。它可以增加食物供应，改善饮食质量，提供获取其他情况下负担不起的食物的途径，并在个人困难和社会冲击期间支持家庭食品供应的稳定性，不过还需要进一步研究来证实这些关系在何时、何地以及如何成立。参与HWFP使人们对其食物来源有自主权，并有助于减少食物采购的生态后果。然而，研究人员已经确定了许多与HWFP相关的食品安全风险，以及这些做法可能威胁粮食系统可持续性的方式。关于HWFP在危机期间以及稳定时期对高收入国家总体粮食供应的贡献潜力，还需要更多研究。HWFP显然对高收入国家的粮食安全有贡献，但这种贡献的许多具体情况仍有待揭示。粮食安全研究人员应进一步考虑HWFP的影响，而研究HWFP活动的学者应将粮食安全视为参与这些做法的驱动力和潜在后果。
