According to the aid agencies, the conflict forced 1.7 million people to evacuate their homes in the Democratic Republic of Congo this year, causing a mega-crisis.
The agencies added that for the second consecutive year, DR Congo is worst-affected by conflict displacement in the world.
DR Congo has been struck by years of instability, with rival militias fighting for control of territory.
"It's a mega-crisis. The scale of people fleeing violence is off the charts, outpacing Syria, Yemen and Iraq," the Norwegian Refugee Council's DR Congo director, Ulrika Blom, said.
"If we fail to step up now, mass hunger will spread and people will die. We are in a race against time," she warned.
