The United Nations High Commissioner for Refugees has said Ireland is scaling up its commitment to support refugees, but expressed concern at the reliance on emergency accommodation for asylum seekers.

Speaking on RTÉ's Morning Ireland, Filippo Grandi said Ireland has taken in 2,500 people under various programmes in recent years and this year it is expected to take in 600 people.

He said while some of the resettlement programmes are small, they are "essential".

Mr Grandi, who is in Dublin for a series of meetings with the Government, is calling on more countries like Ireland - where he said there is stability - to take more refugees through resettlement programmes.

He also said he is concerned by resistance to refugees everywhere, but said it occurs less in Ireland compared to other parts of Europe.

"What happens elsewhere, not really here, what happens in other countries is there are very unscrupulous politicians that are exploiting people's apprehensions and fears for globalisation, for insecurity for economic hardship and they direct that towards foreigners, migrants and refugees," Mr Grandi said.

He said 71 million people around the world are displaced by violence, conflict and discrimination, which he said is the highest figure since the UNHCR started recording these figures with precision and described it as "very worrying".

Mr Grandi added that issues like poverty and bad governance make the response to the international refugee crisis more complex than it has been in the past.

He also expressed concern regarding the increasing reliance on emergency accommodation for asylum applicants, but said he is confident the Government is dealing with the situation.

"I think there is a solution because we are talking about relatively small numbers.

"If I am not mistaken, there are 6,000 people living here under Direct Provision conditions with 1,000 in an emergency situation. I trust that with work being done by the Government, by the Department of Justice, and other parts of the Government, this can be overcome," Mr Grandi said.

However, he commended Ireland's integration of refugees in society and encouraged Irish people to continue in this direction.
