“…Shifting climatic and ecological conditions threaten global food security at a time when the growing human population requires crop yields to increase an estimated + 50% to + 110% by 2050 (Alexandratos and Bruinsma 2012;Ray et al 2013;Tilman et al 2011;van Dijk et al 2021). Domestication and improvement of major crops have led to genetic bottlenecks and reduced diversity due to strong selection for agronomic traits, especially in self-pollinating plant species such as soybean (Glycine max (L.) Merr.)…”

Key message The major soy protein QTL, cqProt-003, was analysed for haplotype diversity and global distribution, and results indicate 304 bp deletion and variable tandem repeats in protein coding regions are likely causal candidates. Abstract Here, we present association and linkage analysis of 985 wild, landrace and cultivar soybean accessions in a pan genomic dataset to characterize the major high-protein/low-oil associated locus cqProt-003 located on chromosome 20. A significant trait-associated region within a 173 kb linkage block was identified, and variants in the region were characterized, identifying 34 high confidence SNPs, 4 insertions, 1 deletion and a larger 304 bp structural variant in the high-protein haplotype. Trinucleotide tandem repeats of variable length present in the second exon of gene Glyma.20G085100 are strongly correlated with the high-protein phenotype and likely represent causal variation. Structural variation has previously been found in the same gene, for which we report the global distribution of the 304 bp deletion and have identified additional nested variation present in high-protein individuals. Mapping variation at the cqProt-003 locus across demographic groups suggests that the high-protein haplotype is common in wild accessions (94.7%), rare in landraces (10.6%) and near absent in cultivated breeding pools (4.1%), suggesting its decrease in frequency primarily correlates with domestication and continued during subsequent improvement. However, the variation that has persisted in under-utilized wild and landrace populations holds high breeding potential for breeders willing to forego seed oil to maximize protein content. The results of this study include the identification of distinct haplotype structures within the high-protein population, and a broad characterization of the genomic context and linkage patterns of cqProt-003 across global populations, supporting future functional characterization and modification.

“…Globally, food demand from a growing population is projected to increase anywhere from 35% to 56% above recent (within the last 10 years) production levels by 2050 [1]. Concurrent with unprecedented food demand, wealth is also expected to increase, thus increasing per-capita consumption of high-protein and high-value foods, with the consumption of more livestock products being a major driver [2].…”

Ecological Intensification of Food Production by Integrating Forages

et al. 2021

Forage crops have the potential to serve multiple functions, providing an ecological framework to sustainably intensify food production, i.e., ecological intensification. We review three categories of forages (annual forages, perennial forages, and dual-use perennial crops/forages) we believe hold the greatest promise for ecologically intensifying food production. Annual cover crops can provide additional forage resources while mitigating nutrient losses from agricultural fields when they are intercropped with, interseeded into, or following an annual crop, for instance. The integration of perennial forages either temporally, such as annual crop rotations that include a perennial forage phase, or spatially, such as the intercropping of perennial forages with an annual cash crop, provide weed suppression, soil quality, and yield and crop quality benefits. Dual-use crops/forages can provide forage and a grain crop in a single year while providing multiple ecological and economic benefits. However, tradeoffs in balancing multiple functions and limitations in reducing the risks associated with these practices exist. Advancing our understanding of these systems so we can overcome some of the limitations will play a critical role in increasing food production while promoting positive environmental outcomes.

“…Shifting consumers away from resourceintensive animal-based foods and toward plantbased alternatives is critical for sustainably feeding a growing global population and mitigating climate change. Recent estimates suggest that the world's food supply will need to increase by up to 62 percent (from 2010) to meet increasing demand (van Dijk et al 2021). As climate change intensifies, demand-side solutions are urgently needed to complement supply-side efforts to produce more food on limited available land.…”

Food production accounts for a quarter of all greenhouse gases, making shifting people’s diets toward lower carbon foods a critical strategy for reducing emissions. This study finds that displaying thoughtfully framed environmental messages on restaurant menus can significantly increase customers' uptake of lower carbon, plant-rich dishes. WRI finds that the two most effective descriptive messages doubled the chance that a consumer would order a vegetarian menu item. These themes are “small changes can make a big difference” and “join a movement of people choosing foods with less impact on the climate.” Restaurants and food businesses should use these findings to increase sales of lower carbon menu items while helping consumers choose foods that fit a climate-friendly lifestyle. While the WRI study was done online with more than 6,000 participants, the findings can be adapted and tailored to a wide variety of retail and food service contexts. More research and real-world learnings will further our base of knowledge. This study, however, shows that adding environmental messaging can be an easy, cost-effective and promising way for companies to see impact and shift consumer choices toward more climate-friendly options.
