“…Several studies have shown that seed mineral content and its response to eCO 2 was highly dependent on the environment (Dier et al, 2020;Fernando, Panozzo, Tausz, Norton, Fitzgerald, Myers, et al, 2012;Fernando, Panozzo, Tausz, Norton, Neumann, et al, 2014;Köhler et al, 2019;Parvin et al, 2019;Samarah et al, 2004;Singh et al, 2016) as well as the cultivar (Beleggia et al, 2018;Myers et al, 2014). Soares et al (2021) also reported stronger declines when using a FACE setting compared with experiments performed in growth chambers (Soares et al, 2019), emphasizing that the experimental set can also affect the results (Bunce, 2016). More studies are needed to improve our mechanistic understanding of the interaction of eCO 2 and growing season conditions and their effects on seed nutrient content.…”

“…In particular, the impact of eCO 2 on Ca, Zn, and Fe has received considerable attention because of their importance to human health (FAO et al., 2021). Several studies have reported a decline in one or more of these elements in soybean (Li et al., 2018; Soares et al., 2021; Soba et al., 2020), other legumes (Högy et al., 2009; Parvin et al., 2019; Saha et al., 2015), and other C 3 crops (Chumley & Hewlings, 2020; Högy et al., 2009; Zhu et al., 2018). Those three elements were also shown to decline under eCO2 in our study, although not consistently in both cultivars and all years.…”

Reduced grain and seed nutrient content in crops grown under elevated CO2 concentrations (eCO2) have raised concerns about future food security. Studies have reported that different seed elements responded differently to eCO2. Additionally, the nutrient response to eCO2 varied across species and cultivars. This study investigated the response of seed quality in two soybean cultivars (HS93‐4118 and Loda) previously shown to have different yield responses to eCO2. We show that seed quality responded differently to eCO2 for the two cultivars and that elements were differentially impacted. The strongest declines under eCO2 were observed for Al, Ca, Fe, and Se while P and Mn were unaffected. Seed protein content increased under eCO2 for the two cultivars. Oil content, however, showed a negative relationship with yield and declined under eCO2. Using path analysis, we show that eCO2 reduced the seed content for some elements through increasing seed yield, effectively diluting the elemental concentrations, while other elements were reduced in a yield‐independent manner. Despite the decline in the seed concentration for some elements, the overall yield per hectare of elements, protein, and oil under eCO2 increased because of greater seed yield. We quantified the economic impact of altered seed composition and show that the decline in oil content with increasing soybean yield at eCO2 could adversely impact profits.

“…All models assume that the seed protein concentration will remain largely unaffected by elevated temperature and CO 2 levels, meaning that soybean yields translate directly into protein yields. Experimental evidence, however, indicates that soybean seed protein may decrease slightly under elevated CO 2 levels (Li et al, 2018; Soares et al, 2021).…”

The European Union is highly dependent on soybean imports from overseas to meet its protein demands. Individual Member States have been quick to declare selfsufficiency targets for plant-based proteins, but detailed strategies are still lacking.Rising global temperatures have painted an image of a bright future for soybean production in Europe, but emerging climatic risks such as drought have so far not been included in any of those outlooks. Here, we present simulations of future soybean production and the most prominent risk factors across Europe using an ensemble of climate and soybean growth models. Projections suggest a substantial increase in potential soybean production area and productivity in Central Europe, while southern European production would become increasingly dependent on supplementary irrigation. Average productivity would rise by 8.3% (RCP 4.5) to 8.7% (RCP 8.5) as a result of improved growing conditions (plant physiology benefiting from rising temperature and CO 2 levels) and farmers adapting to them by using cultivars with longer phenological cycles. Suitable production area would rise by 31.4% (RCP 4.5) to 37.7% (RCP | 1341 NENDEL et al.

“…Well-founded research must support this transition, evidencing how future climate events will impact food safety and nutritional profile, given that current data mainly focuses on crop production in face of weather variables ( Marmai et al., 2022 ). However, there are few recent studies that suggest that the increasing CO 2 levels, heat, drought, or salinity stresses, either single or combined, alter nutrient allocation pathways and accumulation in staple crops, such as soybean and wheat ( Soares et al., 2021 ; Zhara et al., 2022 ).…”

Editorial on the Research TopicThe impact of climate change on nutrient composition of staple foods and the role of diversification in increasing food system resilience A staple food crop is a crop that makes up the dominant part of a population's diet, being the primary source of energy and nutrition. The Food and Agriculture Organization (FAO) reported that maize, rice and wheat provide about 60 per cent of the world's food energy intake. Soybean (an oil crop) is the most commonly used crop in animal feed since it has high protein content. Given the high demand for these four crops, several agricultural technologies and practices have focused on increasing their productivity and adaptation to different environmental conditions (HarvestPlus, 2021). Specific interventions include increased technological investment, biofortification programs, machinery and selective agrochemicals, and advanced agronomic management practices.However, agricultural conditions are rapidly changing due to current climate change events. These include increased greenhouse gas (GHG) concentrations in the atmosphere, global air temperature increase, drought events, sea surface temperature, and erratic precipitation patterns (Jones and Driscoll, 2022). These events harm crop production and setback the developed efforts to ensure a stable supply to the growing world's population. Therefore, food security is at risk, and current food systems are under extreme pressure, which evidences the inequalities in food access and availability, access to land, and the working conditions for farm workers (Farooq et al., 2022). Adding on to food insecurity, undetermined consequences of climate change on agricultural production may also aggravate nutritional insecurity, which consists of the insufficient intake of essential nutritional components, such as vitamins, minerals, protein, or fat (Semba et al., 2022).Current food systems are drivers of the climate change scenario. They contribute to about 35% of the global GHG emissions, biodiversity loss, and water pollution, all of which being highly unsustainable (Xu et al., 2021).
