Okay.
Very specifically, what we find is that for refugees who are in a protracted refugee situation, human rights violations are significantly higher than for those who are not. Long-term exile leads to higher levels of sexual and gender-based violence. It leads to higher instances in crime and insecurity within camps, especially as assistance to the camp-based populations is withdrawn and prolonged exile without a viable foreseeable durable solution frequently leads to irregular secondary movements, so moving to urban centres or seeking a perilous journey to another area.
The very short answer is that there are significant human rights concerns as exile becomes increasingly prolonged.
