Global food insecurity on the rise as more than 820m people go hungry every day

The number of people going hungry has risen for the third year running to more than 820 million, according to a UN report which finds that conflict, climate change and weak economic growth are to blame.

After decades of decline, food insecurity began to increase in 2015 and reversing the trend is one of the 2030 targets of the UN's Sustainable Development Goals.
