Food security policies often overlook the potential of trees to provide micronutrient-rich foods. Here, through causal mediation analysis, we show the positive effect of tree cover on micronutrient adequacy, explained by people sourcing food from on-farm trees. Detailed survey data (n = 460 households with repeated surveys) from Malawi were linked to high-resolution (3 m) tree-cover data to capture forest and non-forest trees. Our findings support integrating nutrition and landscape restoration policies.
粮食安全政策往往忽略了树木提供富含微量营养素食物的潜力。在这里，我们通过因果中介分析表明，树木覆盖对人体从农场树木中获取食物的微量营养素充足程度有积极影响。我们将来自马拉维的详细调查数据（n=460 户家庭的重复调查）与高分辨率（3 米）的树木覆盖数据相联系，以捕捉森林和非森林树木。我们的研究结果支持将营养和景观恢复政策结合起来。
