I'm in Australia. My initial internet searches for Australian strategic food reserves / stockpiles don't seem to turn up anything. Thinking about climate change here in Australia, and how some areas have been subject to quite persistent drought, it doesn't seem completely inconceivable that the whole continent could have a bad season. Having said that, we do export a lot of grain, so you'd think if we'd be able to reduce / halt exports and still feed the nation maybe?
