About 32,000 people have been displaced by conflict and severe drought ravaging several parts of Somalia in October, the UN humanitarian agency said on Thursday.

The UN Office for Coordination of Humanitarian Affairs (OCHA) said in its latest bulletin this is a slight decline in the number of newly displaced people, compared to about 49,000 people displaced in September.

“Of those displaced in October, 23,000 were due to drought-related reasons as the cause of the displacement, while 8,000 cited conflict,” the UN said.

The Horn of Africa nation is in the midst of an unprecedented drought after rains failed for the fourth year in a row.

Humanitarians in Somalia have mobilized 1.2 billion U.S. dollars since January for famine prevention to reach the most vulnerable with life-saving assistance.

The UN agency, which cited figures compiled by the UNHCR-led Protection and Return Monitoring Network (PRMN), said more than 1 million people have been displaced due to drought compounded by armed conflict since January, mainly from rural areas to urban centers.

It said the latest displacements bring the estimated number of displaced in Somalia to more than 2 million people.

“It is imperative to complement humanitarian assistance with more sustainable durable solutions for IDPs, currently making up more than 16 percent of the population,” said OCHA.
