ISLAMABAD - Provisions of instant humanitarian aid to the IDPs hinge on the materialisation of pledges on the part of donors even though funding situation has shown an evident improvement. Saudi Arabia in September last had pledged $100 million for the rehabilitation of IDPs of Pakistan. Information provided by United Nations to this newspaper reveals that the said aid pledge, which would be the largest aid contribution by any donor in the recent months, has not been received yet. Although Saudi authorities have assured us that the financial aid would reach UNs bank accounts very soon, but it hasnt happened so far, we hope that Saudi Arabia would expedite the matter on urgent basis, a UN staffer told TheNation. It is worth remembering that a UN delegation led by senior officials of the international body had visited Saudi Arabia in summer last year for negotiations with Saudi government to discuss modalities and conditions regarding proposed aid pledge. On delegations return, UN had declared that the negotiations with Saudi government were successful and Pakistan would be provided with hefty unconditional aid for IDPs by Saudi Arabia. Soon after, Saudi Arabia had pledged $100m aid for IDPs, which has not been received till date. According to UNs data, over 90 percent or 2,430,000 of 2.7 million IDPs of Swat and Malakand division are back in their native towns, while 270,000 are displaced or have preferred to live with host communities. On the other hand, over 430,000 registered and 200,000 unregistered IDPs of South Waziristan are still displaced sheltering in different cities across the country. The funding percentage for South Waziristans IDPs, which nearly touches 72 percent or 490m (approx), is partially sufficient and immediate influx of funds is vital keeping in view the collective number of the displaced masses of Swat, Malakand division and SWA. If materialised, the Saudi aid pledge could give a mega boost to required funding from $490m to $590m increasing the percentage of collected funds from 72 percent to over 86 percent. United Nations in 2009 struggled with the influx of funds till July, but the materialisation of over $200m of aid pledges by Brazil, Spain, Norway and Canada proved a major breakthrough for the rehabilitation of the affectees of operation Rah-e-Rast.
