The rising carbon dioxide concentrations are expected to increase future rice yields. However, variations in the CO2 fertilization effect (CFE) between rice subspecies and the influence of concurrent global warming introduce uncertainty in future global rice yield projections. Here we conducted a meta-analysis of rising carbon dioxide field experiments and employed crop modelling to assess future global rice yields for the top 14 rice producing countries. We found a robust parabolic relationship between rice CFE and temperature, with significant variations between rice subspecies. Our projections indicate that global rice production in the 2050s is expected to increase by 50.32 million tonnes (7.6%) due to CFE compared with historical production. Because low-income countries will experience higher temperatures, the gaps (difference of Δyield) between middle-to-high-income and low-income countries are projected to widen from the 2030s to the 2090s under elevated carbon dioxide. These findings underscore the critical role of CFE and emphasize the necessity to increase investments in research and technology for rice producing systems in low-income countries. Accurately predicting how much rising atmospheric carbon dioxide can increase rice production is important for managing global rice production. This study highlights that elevated carbon dioxide will boost rice yields more in middle-to-high-income countries than in low-income countries, and that this yield gap will continue to widen in the future.

Rising atmospheric carbon dioxide concentrations and temperature unevenly affect the two main rice subspecies, which is predicted to increase the yield gap between low-income and middle- to high-income countries later this century.

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. Trees are an important source of food. Combining household surveys with high-resolution land-cover data, a causal mediation analysis shows how sourcing food from on-farm trees mediates the positive effect of tree cover on micronutrient adequacy in Malawi.

We employed a function-oriented single-cell Raman approach to identify, quantify and sequence active phosphorus solubilizing bacteria from complex soil matrices. The in situ behaviour of phosphorus solubilizing bacteria across diverse soil and fertilization regimes, as well as the key taxa driving active phosphorus solubilization and the genetic determinants underpinning this function, were identified.

Following the 2023 Mexican Healthy and Sustainable Dietary Guidelines could improve health and reduce the environmental impact and cost of diets, mainly by cutting down on red meat and processed food. In southern rural areas, however, the water footprint and cost of following these guidelines could rise due to increased consumption of nuts, fruits and vegetables.

The 2023 Mexican Healthy and Sustainable Dietary Guidelines (HSDG 2023) were developed to include all dimensions of sustainability. Here we compare the environmental impact and cost of diets based on the HSDG 2023, current diets and the Mexican-adapted EAT healthy reference diet. Diets following HSDG 2023 are 21% less expensive, require 30% less land to be produced and have 34% less carbon emissions than current diets—particularly in Mexico City and other urban areas with higher prevalence of Westernized diets. This is driven by reduced animal-source food, especially red meat, and ultra-processed foods. In south–rural areas, the water footprint and cost of diets following HSDG 2023 were higher than those of current diets owing to increased intake of nuts, fruits and vegetables not offset by lower meat consumption (which is already close to recommendations). Diet environmental impact and cost could be further reduced with the Mexican-adapted EAT healthy reference diet compared with the HSDG 2023. Sustainability is increasingly integrated into national food-based dietary guidelines, but how and to what effect requires investigation. This study analyses the costs and environmental impact of the 2023 Mexican Healthy and Sustainable Dietary Guidelines (HSDG) relative to current diets and the Mexican-adapted EAT healthy reference diet.

Phosphate-solubilizing bacteria (PSB) are crucial for enhancing phosphorus bioavailability and regulating phosphorus transformation processes. However, the in situ phosphorus-solubilizing activity and the link between phenotypes and genotypes for PSB remain unidentified. Here we employed single-cell Raman spectroscopy combined with heavy water to discern and quantify soil active PSB. Our results reveal that PSB abundance and in situ activity differed significantly between soil types and fertilization treatments. Inorganic fertilizer input was the key driver for active PSB distribution. Targeted single-cell sorting and metagenomic sequencing of active PSB uncovered several low-abundance genera that are easily overlooked within bulk soil microbiota. We elucidate the underlying functional genes and metabolic pathway, and the interplay between phosphorus and carbon cycling involved in high phosphorus solubilization activity. Our study provides a single-cell approach to exploring PSB from native environments, enabling the development of a microbial solution for the efficient agronomic use of phosphorus and mitigating the phosphorus crisis. Phosphate-solubilizing bacteria (PSB) are crucial for enhancing phosphorus bioavailability and regulating phosphorus transformation processes. This study employed a function-oriented single-cell Raman approach to identify, quantify and sequence active PSB from complex soil matrices to explore the mechanisms of phosphorus solubilization for efficient phosphorus management.
