UNITED NATIONS (AFP) - A UN envoy pressed donors Tuesday for urgently needed funds for an estimated 1.3 million displaced persons in strife-torn northwest Pakistan amid warnings that some aid projects may have to be cut. Jean-Maurice Ripert, the UN special envoy in charge of humanitarian affairs for Pakistan, said he had just met donors to complain about inadequate funding for the 537-million dollar UN humanitarian appeal launched in February for Pakistans internally displaced people (IDPs). We are becoming a little bit nervous and worried about the financing, he told reporters at UN headquarters, warning that there was no funding at all for sectors such as agriculture or education in Pakistans northwest and rugged tribal regions. I met with donors this morning to launch a new appeal to cover this, he added. Monday, the UN humanitarian coordinator for Pakistan, Martin Mogwanja, said in Islamabad that the world body had so far received only $106m from the donors, barely 20 percent of the total appeal. Humanitarian actors responding to the needs of the people are concerned that some of the projects may have to be suspended because of lack of finances, Mogwanja said. Last year, a total of 3.1 million people were displaced from their homes in Pakistans North West Frontier Province and the semi-autonomous Federally Administered Tribal Areas along the Afghan border. Ripert, a former French ambassador to the UN who was assigned as UN envoy to Pakistan last October, said the number of IDPs was now down to roughly 1.3 million, most of them sheltered in host communities and only 126,000 living in camps.
