Just when some worldwide food supplies are declining, now the UN says there may be a shortage of global rice production.  This is caused by new UN agricultural regulations forcing farmers to use new methods of growing rice to prevent the release of greenhouse gases.  This transitioning is "needed" to prevent climate change affecting our weather with such things as drought and flooding.  But if rice is destabilized it may cause millions of people worldwide to be adversely affected since rice provides up to 50% of the dietary caloric supply they need.
