New York - An estimated $40bn is needed annually to help the rapidly growing number of people needing humanitarian aid as a result of conflicts and natural disasters, a UN-appointed panel says.
It added that one possibility to help fill the $15bn funding gap was a small voluntary tax on tickets for soccer games and other sports, concerts and entertainment events, airline travel, and fuel.
The panel's report on humanitarian financing, launched on Sunday by UN Secretary General Ban Ki-moon at an event in Dubai, says the world is spending around $25bn today to provide life-saving assistance to 125 million people devastated by wars and natural disasters - more than 12 times the $2bn that was spent in 2000.
"We have an exponentially growing problem," said panel co-chair Kristalina Georgieva, the European Commission's vice president for budget and human resources. "The good news is that the world has never been so generous to people in need. The bad news is that never has our generosity been so insufficient."
The nine-member panel calculated that an additional $15bn is needed annually to reduce suffering and ensure that no one in need dies or has to live "without dignity" for a lack of money.
"This is a lot of money, but not out of reach for a world producing $78 trillion of annual GDP," the panel said in the report.
Ban met with the panellists in Dubai to thank them for their work and discuss their recommendations to tackle the shortfall in humanitarian funding.
"Since they began their work the needs created by the demand for humanitarian aid have continued to rise dramatically. We are living in the age of the mega-crises. But, as this report clearly demonstrates, the gap in funding is a solvable problem," Ban said at the launch event, according to the UN spokesperson's office.
At a news conference, Ban noted that three out of four UN appeals for humanitarian funding for more than a billion dollars are in the Middle East and North Africa. He added that "Globally, the world is shattering records we would never wish to break."
The 31-page report focuses on three inter-linked solutions to address the widening financial gap: mobilising additional funds, shrinking the need for aid, and improving the efficiency of humanitarian assistance.
The report says that today's massive instability and its capacity to cross borders, demonstrated by the flight of people from Syria and other conflict areas to Europe, "makes humanitarian aid a global public good that requires an appropriate fundraising model".
It recommends that at the first UN humanitarian summit, to be held in Istanbul in May, governments voluntarily sign up to "the successful model of a solidarity levy and create a steady flow of revenues for humanitarian action".
The report points to a small levy on airline tickets, initially proposed by France, which raised €1.6bn between 2006 and 2011 from just 10 participating countries - Georgieva estimated this at $2.3bn - to help fund diagnosis and treatment for HIV/Aids, malaria and tuberculosis in low-income countries.
Georgieva said in a video briefing from Brussels before the report's release that the panel couldn't agree on the specifics of a levy because some members are against taxation.
But she said she is "more optimistic on a voluntary levy, especially combined with social responsibility".
The panel has talked about a small tax on "high-volume transaction businesses" like Uber, concerts, entertainment, movies and sports and has been talking to some "potential players" including FIFA, the governing body of world football, Georgieva said.
She said people probably wouldn't feel a five-cent or 10-cent addition to a ticket or a ride, but the money generated could have a major humanitarian impact.
The report also calls for governments with greater wealth to provide more aid, for the humanitarian community to "harness the power of business to deliver its key skills and capabilities", including by supporting the delivery of aid and creating jobs, and for Muslim countries, which are most affected by conflict, to use "Islamic social finance" to help meet humanitarian needs.
Georgieva said zakat, the annual donation many Muslims are religiously required to make as a basic tenet of the Islamic faith, raises between $300bn and $500bn a year, and earmarking just 1% of that for humanitarian aid would go "a long way" toward closing the $15bn gap.
To shrink the need for aid, the panel calls for world leaders to commit to preventing and resolving conflicts and to increasing investments in reducing the risk of natural disasters. In addition to putting more money in these areas, it recommends that aid should focus on "fragile countries" and countries experiencing shocks due to conflicts or natural disasters.
The panel also recommends that humanitarian aid should follow people in need, not countries. Georgieva said this means, for example, that when people fleeing conflict move from Syria to Lebanon and Jordan, those middle-income countries can get access to grants and low-cost loans.
To improve aid delivery, the panel calls for an end to competition between aid organisations and between humanitarian and development agencies.
It calls for donors and aid organisations to come together in "a grand bargain" in which donors provide more cash, long-term, with fewer strings and aid organisations are more transparent so that everyone can "follow the money".
