摘要 与不良饮食质量相关的营养不良影响着至少 20 亿人。森林以及与树木相关的农业系统是农村地区饮食多样性的主要来源。在本文中，我们建立了饮食多样性与热带乡村森林景观马赛克之间的概念联系。首先，我们总结了有关从森林、树木和农林中获得的饮食的知识状况。然后，我们假设受干扰的次生林、边缘栖息地、森林通道和景观多样性如何在促进饮食多样性方面发挥作用。总而言之，这些想法帮助我们建立了一个框架，阐明了将森林景观与饮食多样性联系起来的四种途径（直接途径、农业生态途径、能源途径和市场途径）。最后，我们提出建议，以填补与饮食和森林覆盖监测相关的剩余知识空白。我们认为，更好地评估土地覆盖复杂性的作用将有助于避免对粮食安全过于简单化的看法，而是揭示营养与森林保护和恢复的协同作用。
Abstract Malnutrition linked to poor quality diets affects at least 2 billion people. Forests, as well as agricultural systems linked to trees, are key sources of dietary diversity in rural settings. In the present article, we develop conceptual links between diet diversity and forested landscape mosaics within the rural tropics. First, we summarize the state of knowledge regarding diets obtained from forests, trees, and agroforests. We then hypothesize how disturbed secondary forests, edge habitats, forest access, and landscape diversity can function in bolstering dietary diversity. Taken together, these ideas help us build a framework illuminating four pathways (direct, agroecological, energy, and market pathways) connecting forested landscapes to diet diversity. Finally, we offer recommendations to fill remaining knowledge gaps related to diet and forest cover monitoring. We argue that better evaluation of the role of land cover complexity will help avoid overly simplistic views of food security and, instead, uncover nutritional synergies with forest conservation and restoration.
