Other claims from this paper (6)
- Observation Farmers applied 25% of the irrigation water required for maximum potential grain yield in 2018–2020.
- Observation Actual wheat yields were below 50% of potential yields.
- Observation RCP4.5 projected a 3% increase in irrigation water demand by century end.
- Mechanism Reduced irrigation demand under RCP8.5 was attributed to truncated crop duration and lower maturity biomass.
- Observation Simulated wheat yields declined by 20% under climate change.
- Recommendation Authors infer irrigation alone will not offset climate damage to crop production.
