The challenge to eliminating child labour and forced labour I think is captured by the number 5.5 million. If you look at the 2005 forced labour estimates, the estimate of child slavery in the world was 5.5 million. In 2012, that number was 5.5 million. In 2017, the number has risen to about 10 million, because forced child marriage was finally recognized as being a form of child slavery as well.
The reason I refer to this number is that during this time period, we've seen a significant decline in the number of children in child labour in the world, including its worst forms, but no impact on the number of children in slavery, which suggests that there has been no impact whatsoever on the number of people in slavery.
In spite of many fine words and some fine action in relation to the broader question of child labour, we're not seeing any progress whatsoever in the issue of slavery. This suggests that we need to rethink, quite fundamentally, how we're doing some very big things, starting with international trade, and working our way down to the way in which we practise development, humanitarian response, and particularly education.
I think I'll leave it at that, and we can discuss it further as we're going along.
