GENEVA (AFP) A UN refugee official suggested on Tuesday that Pakistans geopolitical stability was at stake unless international aid accelerates to help about 20 million Pakistanis hit by devastating floods. The office of the UN High Commissioner for Refugees (UNHCR) said that the situation remained critically difficult in some areas, while shelter and recovery for hundreds of thousands of people was still short nearly 10 weeks since flooding began. We need to draw the international communitys attention that the emergency in Pakistan is not over, said Mengesha Kebede, the UNHCRs representative in the country. Making sure 20 million people are rehabilitated I think is an international obligation: we are looking at a geopolitical situation where the stability of Pakistan we feel is in everybodys interest, he told journalists in Geneva. Donors have so far funded just one-third of the $2.0b UN aid appeal, while the UNHCRs shelter needs are only half funded, a situation Kebede dismissed as unacceptable. In hard-hit Sindh and Balochistan provinces, a total of about 2.7m people are still displaced. Kebede underlined that about 600,000 displaced had sought shelter in schools in Balochistan, where local authorities wanted to reopen them to start schooling again. However, many of the displaced could not return to damaged homes and supplies to set up huge tented camps were short. That kind of challenge continues on a daily basis in every province, Kebede added. UNHCR is also caring for the worlds largest refugee population in Pakistan, some 1.7 million Afghan refugees, many of whom were in flood hit areas. Another 1.2 million Pakistanis are still displaced by conflict in the northern Khyber Pakhtunkhwa province. That problem has become secondary because of the magnitude of the floods. Now that the floods have started receding it will definitely start surfacing again because the conflict continues, said Kebede.
