Change Type: Correction
Change Details: In the version of this article published online and in print, there was a mistake in the legend of Fig. 2 regarding the descriptions of the red and blue colours in the Figure. The text should have read ‘The blue and red colours represent regions (provinces) with wheat and rice as the staple food, respectively.’ This has now been corrected in the HTML and PDF version of the article.
