In northern Serbia, in Novi Sad, small boats sit idle on cracked ground in a shriveled side channel of the Danube River, where water has receded into a couple of shrinking ponds. This was reported by Qazaqyia.kz citing Associated Press.

Fisherman Dusan Jovanovic said: "This is all we have, these two little ponds that are full of juvenile fish." He noted the fish are in danger because there is too little water and its temperature is over 30 degrees Celsius.

"If they start to die, they will all die at once," Jovanovic added.

Persistent drought and scorching heat this summer have ravaged ecosystems and businesses across the region, from a lake in Slovenia to the side channel of the Danube in Serbia.
