Climate change is affecting the cultivation of Assam tea, with rising temperatures reducing yields and altering the distinctive flavour of India's most popular drink, researchers say.
The Tea Board of India said it had recorded a steady decline in tea production in recent years. In 2007, Assam produced 512,000 tonnes of tea. By 2008 this had declined to 487,000 tonnes, with estimated production in 2009 down again to 445,000. A further decrease is expected this year.
Thanks to a comment by AntonyIndia, and adding in the stats from the site, we can see the stats since 2001 (which I've helpfully charted for you good people):-
So, even if there's been a decline the past 2 years, it's still above what it was in 2002 and 2003 (which were below 2005-2008).
