Summary: Crop diversity in intercropping systems affects the productivity and resource utilization efficiency. The below ground interactions between maize and soybean in relay strip intercropping have been found to enhance root development and water uptake. The swapping of rows in intercropping further improves the productivity and resource use efficiency.

Summary: Climate change has a global impact on soil microbial community composition in various ecosystems. However, the effects of warming on soil microbial community structure and the underlying mechanisms in subtropical forest ecosystems remain poorly understood. To fill this research gap, an altitudinal gradient was used to simulate ecosystem warming, and after 6 years, it was found that microbial co-occurrence network complexity increased with warming. The taxonomic composition changes were asynchronous, likely due to different community assembly processes. Stochastic processes drove bacterial community composition, but warming led to a shift from stochastic to deterministic drivers during the dry season.

Summary: This study investigated the effects of CO2 and O3 enrichment on the dynamics of the soil bacterial community in paddy soils. The results showed that CO2 and O3 enrichment had no significant effect on the abundance and diversity of the soil bacterial community. However, O3 enrichment significantly reduced the relative abundance of the Myxococcota phylum, and both CO2 and O3 enrichment decreased the network complexity of the soil bacterial community.

Summary: This study found that intercropping with multiple crops significantly increased soil aggregates and ecosystem functions, such as enzyme activities and microbial biomass. In addition, intercropping enhanced the diversity of bacteria and fungi and promoted their ecological communities. These results are important for understanding microbial diversity and ecosystem functioning in intercropping systems and guiding agricultural practices.

Summary: The quality of wheat grain, which is crucial for human nutrition, is often neglected when focusing on crop production in stressed environments. Climate change, with combined stresses such as elevated CO2 concentrations and extreme climatic events, affects the quality and composition of wheat grain. This study highlights the limited data and lack of global efforts in assessing climate risks on wheat grain quality. Climate-change events, including eCO(2), heat, drought, salinity stress, and their combinations, alter various aspects of wheat grain quality, such as weight, nutrient content, fiber content, protein composition, starch granules, and free amino acid composition. Different stress types and exposure conditions also influence grain quality components. Impairment of wheat productivity and degradation of grain quality can occur due to disrupted nutrient allocation and assimilation under rapid climate shifts.

Summary: Soil microbe diversity is influenced by altered precipitation and plant biodiversity attributes such as species richness and plant height, as well as soil properties like soil water content, in desert-shrub and steppe-grass communities. The effects of precipitation on soil bacterial and fungal richness are mediated differently by plant biodiversity attributes and soil properties along natural and experimental gradients. Long- and short-term precipitation changes have the potential to modify the relationship between plant and soil microbial diversity in water-limited areas.

Summary: Climate change poses a significant challenge to agricultural production in developing countries, particularly in relation to extreme weather events and their impact on crop yields. By utilizing a conditional dependence model for multivariate extreme values, this study examines the probability of extreme events leading to substantial reductions in harvest for major crops across different countries. The findings reveal a high heterogeneity in both countries and crops, enabling the assessment of crop resilience to climate shocks on a country-specific and crop-specific basis.

Summary: This review summarizes the potential effects of climate change on agricultural yield and micronutrient quality of plant foods, as well as the availability of animal foods. The study suggests that climate change is likely to affect the availability of micronutrient-rich foods, rather than their nutrient content. Mitigating and adaptive strategies should be considered to reduce the risk of micronutrient deficiencies in vulnerable populations.

Summary: This article discusses the importance of long-term ecological research in understanding the response of ecosystems to climate change. The study found that air temperature and moisture variability have increased in diverse ecosystems, leading to changes in primary production and matter cycling. The research also highlights the unique drivers of change in different regions and the interactions between climate change drivers and human activities.

Summary: This study investigates the interactive effects of elevated CO2 and biochar addition on plant C:N:P stoichiometry and rhizobacterial community. The results show that elevated CO2 and biochar have opposite effects on plant biomass, nitrogen and phosphorus uptake. The rhizobacterial community in the subsoil has a greater diversity of contrasting species associated with nutrient cycling, hydrocarbon degradation, and plant productivity.

Summary: Nutrients such as nitrogen (N), phosphorus (P), sulfur (S), zinc (Zn), and iron (Fe) are essential for the optimal growth, development, and productivity of plants. Plant responses to deficiencies of these nutrients are mainly studied separately, but there is limited research on the molecular basis of interactions among them. Recent advances have identified master regulators like phosphate starvation response 1 (PHR1) and light-responsive transcription factors involved in coordinating nutrient responses in plants. Understanding the interactions between macro- and micro-nutrients could help breeders improve nutrient use efficiency and crop yield/quality, especially in the face of changing climatic conditions.

Summary: Well-managed legume-based food systems have the potential to mitigate climate change by reducing GHG emissions while providing benefits like improved ecosystem functions, reduced biodiversity loss, and better human health and nutrition. Despite being underutilized in Europe and globally, integrated, diverse, legume-based, regenerative agricultural practices should be implemented at appropriate bioregional scales to optimize production and safeguard food security. This approach requires complex solutions and must be supported by concerted policy action to harness the transformative capacity of legumes and ensure the establishment of knowledge networks and new value-chain capacities.
