Humanitarian agencies at the UN climate summit in Madrid say refugee camps in Africa and Asia are increasingly being damaged by extreme weather.
They say this has significantly added to the challenges they face in operations around the world, as already displaced people have in some cases been forced to move again.
Scientists warn that flooding and violent storms will become the new normal if the planet continues to warm at the current rate, adding to the hardship of those already displaced by conflict.
When tropical cyclone Idai hit south-east Africa, killing more than 1,000 people in March this year, a refugee camp in Zimbabwe was affected too, according to the UN refugee agency (UNHCR) officials.
They said many were injured in the Tongogara refugee camp that hosts some 13,000 refugees in Chipinge district.
“Around 2,000 refugee houses, mainly built using mud bricks, were completely or partially damaged,” the UNHCR said at the time.
“Over 600 latrines have collapsed, and borehole water is feared to be contaminated due to flood waters. There is a real danger of an outbreak of waterborne diseases.”
