World Food Prize mentions that Dr B.R. Barwale is the 1998 recipient of that award. Google has it that Mr Barwale was born in 1931 in India.
Because Wikipedia does not know that Mr Barwale was born in 1931, he is not in a category "Born in 1931" and consequently Wikidata did not know that Mr Barwale was a human and therefore he was not automatically awarded the World Food Prize.. This was added by hand.
The World Food Prize has a website, it mentions Mr Barwale in plenty of detail. Arguably, as a source the website of the World Food Prize provides many details for its laureates. It is however like Wikipedia not a source that makes for easy automated comparisons.
