TL;DR: The questions for this chapter are how far climate and its change affect current food production systems and food security and the extent to which they will do so in the future.

TL;DR: This eight-year study used precipitation manipulation and year-to-year variation in weather conditions at a unique open-air field facility to show that the stimulation of soybean yield by elevated [CO2] diminished to zero as drought intensified.
Journal ArticleDOI
Reduction of transpiration and altered nutrient allocation contribute to nutrient decline of crops grown in elevated CO2 concentrations
TL;DR: Nutrients acquired mostly by mass flow were decreased significantly more by elevated [CO(2) ] than nutrients acquired by diffusion to the roots through the soil, supporting the first hypothesis and Mg showed large concentration declines in leaves and wheat stems, but smaller decreases in other tissues.
Journal ArticleDOI
Genomic basis for stimulated respiration by plants growing under elevated carbon dioxide
Andrew D. B. Leakey,Fangxiu Xu,Kelly M. Gillespie,Justin M. McGrath,Elizabeth A. Ainsworth,Donald R. Ort +5 more
TL;DR: Great respiratory quotient and leaf carbohydrate content at elevated [CO2] indicate that stimulated respiration was supported by the additional carbohydrate available from enhanced photosynthesis at elevated [*CO2], which could facilitate greater yields through enhanced photoassimilate export to sink tissues.
Journal ArticleDOI
Can the cyanobacterial carbon-concentrating mechanism increase photosynthesis in crop species? A theoretical analysis.
TL;DR: A model incorporating the full cyanobacterial carbon-concentrating mechanism into C3 plants indicates that CO2 uptake rate could be increased by 60%, thus increasing yield during a time when yield growth has stagnated and decreasing photorespiration.
