Other claims from this paper (11)

Intervention effect Climate change has adversely affected wheat yield, especially rain fed wheat in Iran and elsewhere.
Observation Some studies report wheat yield changes greater than the 10-14% estimate.
Mechanism Temperature increase and heat stress are identified as the most important factor in wheat climate impacts.
Intervention effect Climate change can reduce the wheat crop growth period.
Intervention effect Climate change can reduce the planting-to-flowering period.
Intervention effect Climate change can shorten the seed filling period.
Intervention effect Climate change can reduce the flowering-to-maturity and seed production period.
Recommendation Adaptation measures include heat-tolerant, low-water-requirement cultivars, longer-growing cultivars and planting date changes.
Recommendation Adaptation measures include improved on-farm water management, residue management and increased soil organic matter.
Recommendation Wheat adaptation strategies should focus on reducing temperature and heat stress effects, especially at critical growth stages.
Recommendation Climate effects on strategic crops should be mainstreamed and prioritized in national and sub-national research, especially in Iran, to ensure food security.
