Corn, a staple crop introduced by Native Americans, now faces a precarious future due to climate change. This crop, pivotal in global food systems, may see significant yield declines as global warming progresses.
Corn's ability to efficiently convert sunlight into energy through the C4 photosynthetic pathway has historically given it advantages in productivity and drought resistance.
This same trait may become a disadvantage with rising CO2 levels, which benefit C3 plants like wheat and rice more than C4 plants like corn.
Recent studies suggest that by the end of this century, corn yields could decrease by up to 24%, while crops like wheat might see an increase of 18% in yields.
This shift could profoundly affect everything from food prices to biofuel production and even the ability of our ecosystems to sequester carbon.
Additionally, less than a third of the corn grown in the U.S. is directly consumed by humans. Most are processed into additives like high-fructose corn syrup or used as feed for livestock. The potential decrease in corn production could thus have far-reaching effects on dietary patterns and meat availability.
As we approach future Thanksgiving celebrations, the traditional corn dishes might become rarities, symbolizing a deeper shift in our agricultural landscape.
This underscores the urgent need for adaptive agricultural techniques and crop diversification to sustain our food systems in the face of climatic changes.
