Cindy Holleman, a senior economist at the Food and Agriculture Organisation, explained that rises in man-made conflict and climate change, which usually occur alongside economic slowdowns, make it harder for poor people to get access to food.
According to an economic report, published on Friday by the Federal Minister for Family Affairs, the number of children threatened by poverty in Germany rose by around 200,000 between 2010 and 2015.
Two years ago 20% of children in Germany were threatened by poverty, constituting a rise of 1.5 percentage points over five years.
The report found that a total of 2.8 million under-eighteens were living in households with an income per person of less than 60% of the national average.
A crucial factor behind this development has been the influx of migrant children over the past few years.
