Problem:
The ground of membership of a particular social group was not included in the refugee definition in the 1950 statue of the UNHCR. It was added later on in the refugee definition of the 1951 convention relation to the status of refugees and subsequent definitions.
Why was it added??
Its effect was not felt immediately, but in a recent years it has had a significant impact, why?
How and in what areas has this impact been felt?
Note: please be very specific and focused on the question itself. Examples and explanations with analytical skills answers/research.
