Malnutrition and climate change are intimately linked. Nature Food’s latest Collection illustrates the central role of diets in both of these issues, underscoring the burden of current diets on human and planetary health, as well as how much improvement can be achieved through better dietary choices.

Carbon sequestration on agricultural land, albeit long-time neglected, offers substantial mitigation potential. Here we project, using an economic land-use model, that these options offer cumulative mitigation potentials comparable to afforestation by 2050 at 160 USD2022 tCO2 equivalent (tCO2e−1), with most of it located in the Global South. Carbon sequestration on agricultural land could provide producers around the world with additional revenues of up to 375 billion USD2022 at 160 USD2022 tCO2e−1 and allow achievement of net-zero emissions in the agriculture, forestry and other land-use sectors by 2050 already at economic costs of around 80–120 USD2022 tCO2e−1. This would, in turn, decrease economy-wide mitigation costs and increase gross domestic product (+0.6%) by the mid-century in 1.5 °C no-overshoot climate stabilization scenarios compared with mitigation scenarios that do not consider these options. Unlocking these potentials requires the deployment of highly efficient institutions and monitoring systems over the next 5 years across the whole world, including sub-Saharan Africa, where the largest mitigation potential exists. Carbon sequestration on agricultural land holds great promise for combating climate change. This study estimates the mitigation potential of three sequestration practices—soil carbon enhancement, biochar application on cropland and silvo-pastoral systems—while identifying cost-effective mitigation portfolios.

An integrated assessment study reveals that carbon sequestration options on agricultural land offer substantial mitigation potential. Tapping this potential could enable net-zero land-use emissions to be achieved by mid-century at lower greenhouse gas prices, increase revenues for farmers and decrease economy-wide costs of climate action, compared with a scenario that does not consider these options.

Food waste reduction is essential for supporting the sustainability of food systems. Wasteful behaviours are difficult to change after they have been formed, highlighting the importance of early interventions. Here we present an assessment of school plate food waste from 29 countries, and examine the environmental implications, causes, and interventions. School plate waste ranged from 4% to 46% per capita per meal and was positively correlated with country income levels. On a global scale, this waste embodies ∼150 Mha of cropland and ∼770 MtCO2e of greenhouse gas emissions; hence, reducing school plate food waste offers potentially large environmental gains. We propose a comprehensive, multistakeholder framework centred around sustainable food education that cultivates food systems knowledge and skills, and an appreciation for nature and food labour to reduce the psychological distance between youth and their food waste. To effectively implement the framework requires the support and engagement of families, communities and the broader society beyond the confines of schools. A dataset including 29 countries and life-cycle assessment highlights the environmental impact of school plate food waste. A sustainable food education framework is presented to support early intervention and wasteful behavioural changes.

Climate variability plays a crucial role in the annual fluctuations of crop yields, posing a substantial threat to food security. Maize, the main cereal in sub-Saharan Africa, has shown varied yield trends during increasingly warmer growing seasons. Here we explore how sub-seasonal dry–wet spell patterns contribute to this variability, considering the spatial heterogeneity of crop responses, to map weather-related risks at a regional level. Our results show that shifts in specific dry–wet spell patterns across growth stages influence maize yield fluctuations in sub-Saharan Africa, explaining up to 50–60% of the interannual variation, which doubles that explained by mean changes in precipitation and temperature (30–35%). Precipitation primarily drives the onset of dry spells, while the influence of temperature increases with event intensity and peaks at the start of the growing season. Our large-scale, data-limited analysis approach has the potential to inform climate-smart agriculture in developing regions. Maize yield variability in sub-Saharan Africa has important implications for food security and livelihoods. By combining the time specificity of weather-related impacts on crops and different agroclimatic zones, this study shows that shifts in sub-seasonal dry–wet spell patterns are a major contributor to this variability.

Brown planthoppers (Nilaparvata lugens) and white-backed planthoppers (Sogatella furcifera) are among the most destructive pests on rice. However, plant susceptibility genes have not yet been exploited for crop protection. Here we identified a leucine-rich repeat protein, OsLRR2, from susceptible rice varieties that facilitates infestation by brown planthopper N. lugens. Field trials showed that knockout of OsLRR2 significantly reduced BPH infestation and enhanced natural biological control by attracting natural enemies. Yield of a susceptible variety was increased by 18% in insecticide-treated plots that eliminated planthoppers and by 25% in untreated plots. These findings underscore the pivotal role of OsLRR2, offering a promising pathway for pest population suppression and rice yield increase. Planthoppers are among the most destructive pests on rice. This study identified that a leucine-rich repeat protein OsLRR2 negatively regulates defence responses. Knockout of the encoding gene OsLRR2 enhances rice herbivore resistance and yield, which holds the potential to produce high-yielding rice varieties that are resistant to devastating pest insects.

Plant factories with artificial lighting (PFALs) can boost food production per unit area but require resources such as carbon dioxide and energy to maintain optimal plant growth conditions. Here we use computational modelling and artificial intelligence (AI) to examine plant–environment interactions across ten diverse global locations with distinct climates. AI reduces energy use by optimizing lighting and climate regulation systems, with energy use in PFALs ranging from 6.42 kWh kg−1 in cooler climates to 7.26 kWh kg−1 in warmer climates, compared to 9.5–10.5 kWh kg−1 in PFALs using existing, non-AI-based technology. Outdoor temperatures between 0 °C and 25 °C favour ventilation-related energy use reduction, with outdoor humidity showing no clear pattern or effect on energy use. Ventilation-related energy savings negatively impact other resource utilization such as carbon dioxide use. AI can substantially enhance energy savings in PFALs and support sustainable food production. Plant–environment interactions are examined using artificial intelligence and computational modelling, allowing energy use to be optimized in plant factories with artificial lighting.
人工照明植物工厂（PFALs）可以提高单位面积的粮食产量，但需要二氧化碳和能源等资源来维持植物的最佳生长条件。在这里，我们利用计算建模和人工智能（AI）研究了全球十个气候各异地区的植物与环境之间的相互作用。人工智能通过优化照明和气候调节系统减少了能源消耗，在气候较冷的地区，PFAL 的能耗为 6.42 千瓦时/千克-1，在气候较热的地区为 7.26 千瓦时/千克-1，而在使用现有非人工智能技术的 PFAL 中，能耗为 9.5-10.5 千瓦时/千克-1。室外温度在 0 °C 至 25 °C 之间有利于减少与通风相关的能源消耗，而室外湿度对能源消耗没有明显的模式或影响。与通风相关的能源节约会对其他资源的利用产生负面影响，如二氧化碳的使用。人工智能可以大大提高 PFALs 的节能效果，支持可持续粮食生产。
