The United Nations refugee agency said Monday that needs remain high for hundreds of thousands flood victims in Pakistan as they face the winter in camps or without proper shelter. "The emergency phase of this crisis is not over and many of the most vulnerable flood victims are yet to receive sufficient relief aid," said Mengesha Kebede, UNHCR's Country Representative in Pakistan. Kebede said the situation in Sindh province was of particular concern where large tracts of land were still submerged, delaying return and recovery for the hundreds of thousands of people remaining in camps, schools or spontaneous sites along roadsides. UNHCR's latest monthly survey of camps and spontaneous sites in Sindh found almost 60 percent of the million people in more than 3,000 sites were children, with 21 percent under five years old. Twelve percent of the camp population are people with disabilities. "As with most crises, it is the most vulnerable who live in camps as they have no other option. But the thousands of camps in Sindh are still pitifully under-resourced with many providing just the most basic services," said Kebede. UNHCR's latest survey of Sindh sites found that malnutrition may affect more than 56,000 displaced people but that only 9,600 currently receive supplemental feeding. The survey also found that water and sanitation remains one of the key concerns in displacement sites, as open defecation affects one-third of the total number of displaced people, and cleaning program exist for only 28 percent. Hygiene promotion has been conducted for only 21 percent, and only 20 percent of displaced people have soap. Nineteen percent do not receive sufficient drinking water and half the displaced people report a lack of water for cleaning, washing and feeding livestock. Across Pakistan, UNHCR has distributed more than 100,000 tents, almost 190,000 plastic sheets, 510,000 sleeping mats, 200,000 mosquito nets and almost 1,500 metric tones of soap. UNHCR's revised funding requirement for its Pakistan flood operation until June 2011 is 186 million U.S. dollars with only 41 percent funded.
