In the post-apocalyptic science fiction novel The Death of Grass (and the movie No Blade of Grass), a virus threatens all the world's grass crops. Some governments begin plotting to nuke (their own!) cities to reduce food demand.
There is a worrying analogy to global warming, where governments might consider nuclear war to reduce carbon emissions (from other countries). Though at the point global warming is really bad, it would probably be too late to make much difference.
