Cotton Outlook's world production number for 2012/13 has been raised by 278,000 tonnes, leading to greater carryover in the new season. This is partly due to the emergence of a bumper crop in India.
The 2013/14 global production figure has been revised upwards by nearly 70,000 tonnes. This change is primarily attributed to an increase for China. A decline in consumption (mainly for smaller markets) has also contributed to the surplus of production over consumption.
