It's one of a number of international aid organisations which say they're not getting enough funding to offer support to the increasing numbers of people fleeing conflict.
Gavin Crowden, World Vision UK's Head of Policy and Public Affairs, said: "While much of the focus on the current refugee crisis has been on the Syrian conflict, fighting in South Sudan, Central Africa Republic, Iraq, Yemen and other countries has stretched the limits of our ability to respond.
"That the UN appeal for the Syrian crisis has only been 37-per-cent funded is a reflection of the challenges we face in responding to various protracted crises. And it's children who are being hit hardest.
"Even as the global goals for development were being agreed by governments in New York including on peace and security, humanitarian needs on the ground are not being matched by the funding and political will required.
"Aid agencies alone cannot respond to the growing number of humanitarian crises worldwide and we need to have a discussion on how we can address these challenges."
The organisation hosted a fringe event at the Labour Party conference on Monday which Mr Crowden added was "an opportunity to dissect some of these issues and develop coherent and long-term plans to address to the current shortcomings".
On the panel at the event was the former shadow Secretary of State for International Development Mary Creagh MP.
She said: "I recently visited the Middle East where I experienced the front-line of the refugee crisis.
"Britain has a proud history of giving sanctuary to people fleeing persecution, and we must now honour that legacy.
"The UK has a responsibility to offer support - including taking some of the refugees who are already in southern and eastern Europe.
"We need to urgently bring together local authorities, INGOs and donor governments to develop coherent and long-term plans to address this crisis."
