Subject: Your article on rice yields
Dear Mr. Black,
I’m writing as a courtesy to advise you that I believe your article:
Which says “Yields have fallen by 10-20% over the last 25 years in some locations.”
…is in error.
The actual press release says ”Rising temperatures during the past 25 years have already cut the yield growth rate by 10-20 percent in several locations.”
It is not the gross yield that has supposedly fallen, but the rate of increase in the yield.
Further, I have a graph from the International Rice Research Institute which supports this and demonstrates that gross rice yields are still increasing in Asia:
I think it’s just a simple interpretive error on how you read the press release, but it does have large consequences for how the story is interpreted by readers. Here in Northern California, one of the largest rice growing areas of the world, a call to our local Rice Association confirmed this. A correction might be in order.
Thank you for your consideration.
