BRUSSELS, Nov 17 (Reuter) - The 15-nation European Union and the United States, which between them provide more than 90 percent of world humanitarian aid, will hold a special meeting next month to combat what they called "donor fatigue". With around 45 million refugees now aid-dependent, including $4 billion channelled through the United Nations in 1194, donors were in danger of becoming overwhelmed and giving up the fight. "We need a new awareness and effort to mobilise aid world-wide," EU Humanitarian Aid Commissioner Emma Bonino told a news conference at in Brussels. The meeting, to be held in Madrid on December 14, will draw up guidelines to improve humanitarian aid to present to an EU summit in the Spanish capital the following day. Spain holds the rotating EU presidency until the end of the year. The aid meeting will also discuss ways to strengthen cooperation between EU, U.S. and U.N. and private aid donors. EU aid policy tends to be more politically neutral than that of the United States, Bonino said

, noting that U.S. help for ex-Yugoslavia was focused on Moslems in Bosnia whereas the EU gave support to all the republics, including Serbia. Bonino said the scale of human emergencies had grown in recent years, creating new problems such as breakdown in public order and a decline in safety for aid workers. "The humanitarian problem has completely changed," Bonino said, noting that some refugee camps were like cities with more than 200,000 people. Bonino announced two new aid initiatives for ex-Yugoslavia and for refugees from Rwanda and Burundi. The EU will grant 110 million European currency units ($148 million) aid to help 3.6 million refugees, of which 2.7 million in Bosnia, survive winter in camps in ex-Yugoslavia. "It's a really dramatic situation," Bonino told a news conference. "There's a tragedy in the making this winter." The EU has already given 1.1 billion Ecus ($1.4 billion) in humanitarian aid with a further 500,000 Ecus ($645,000) from member states covering all ex-Yugoslavia since the confli

ct started more than three years ago. The EU will grant 70 million Ecus ($94 million) to help two million refugees from Rwanda and Burundi survive the next six months and assist their return home, Bonino added. "The objective is to finance a series of projects to build confidence and help them return home," Bonino said. Only 100 to 150 a day were returning from camps in Zaire and Tanzania, far below the target of 6,000 daily, a Commission official said. Between 500,000 and a million Tutsis and moderate Hutus are estimated to have been killed by Hutu forces in a four-year civil war in Rwanda.
