Article Synopsis
- * Research using advanced wheat simulation models indicates improved wheat genotypes can boost yields by 16% using current nitrogen fertilizer levels.
- * To reach a potential 52% increase in yield under severe climate change conditions, nitrogen fertilizer use would need to quadruple, which could exacerbate environmental impacts, highlighting the need for better nitrogen management.
Crop multi-model ensembles (MME) have proven to be effective in increasing the accuracy of simulations in modelling experiments. However, the ability of MME to capture crop responses to changes in sowing dates and densities has not yet been investigated. These management interventions are some of the main levers for adapting cropping systems to climate change.

- Potential climate change will negatively affect future crop yields, particularly for maize, soybean, and rice, with new projections showing significant declines in productivity.
- Previous models anticipated slight increases or minor declines, but updated simulations suggest much larger decreases for these crops.
- On the other hand, wheat is expected to see improved yields due to increased CO2 levels, with notable climate impacts emerging earlier than expected, before 2040 in key agricultural regions.
Wheat yield potential in controlled-environment vertical farms.
Proc Natl Acad Sci U S A
August 2020
Scaling current cereal production to a growing global population will be a challenge. Wheat supplies approximately one-fifth of the calories and protein for human diets. Vertical farming is a possible promising option for increasing future wheat production.
