Hassan Khail , Pakistan ( CNN ) -- The white bags land with a thud , a small cloud of dust billowing around them . But for Pakistanis like Tariq Jan , the simple sack may as well be gold . Each 30-kilogram sack contains enough animal feed to keep a donkey satisfied for a month . Without the United Nations donations , Tariq Jan would have no chance of restarting the life that he lost , washed away by the massive flooding that began in Pakistan almost two months ago . He used to own more than 40 animals . But many of them died when his house and his land drowned under torrents of gushing water . His family depends on the milk from the cows . `` They have gotten much thinner , '' he said of his animals . `` I am having a lot of trouble getting anything to eat for them . '' The floodwaters submerged about 10 million acres , much of it in Punjab province , Pakistan 's breadbasket , where people live off the soil and their livestock . The United Nations Food and Agriculture Organization has been trucking in animal feed and seeds to plant anew . `` We have to try and and get seeds in here and make sure they can get off food aid as fast as possible , '' the group 's Truls Brekke said of the flood survivors . Tariq Jan used to profit from several acres of syrupy sugar cane . But now , without any help , it will take perhaps five years before he can clear the sludge and see new shoots again . But even the food aid is falling short . Secretary-General Ban Ki-moon announced a few days ago that the United Nations is seeking another $ 1.594 billion for flood victims , bringing the total to more than $ 2 billion . The world body has received about 70 percent of the $ 460 million it initially requested . Farther south in Sindh , the floods are still adding to the ranks of the homeless . Every day , the United Nations is seeing 20,000 to 30,000 more people who have just lost their homes to rising waters . In all , more than 20 million people were affected by the floods . Waters from Lake Manchar are overflowing in five directions . Some people are referring to it as a `` lake burst , '' said Fawad Hussain , a U.N. relief coordinator for Sindh . `` First we had the rain , then the waters from the river and now the lake , '' Hussain said . `` We have not been able to scale up [ the response ] as quickly in the far south due to lack of funding . '' There are people marooned in Pakistani villages who are still waiting for help . `` The monsoon rains may be over , but the floods are not , '' said Andro Shilakadze of UNICEF . CNN 's Fred Pletigen contributed to this report .
