The flood recovery costs for Pakistan's vital agriculture sector and farmers could be in the billions of dollars, said the spokesman for U.N humanitarian operations on Thursday. "The devastation to crops is immense. I think it's safe to say it will take some billions of dollars to recover. Even though we don't have estimates yet. I am referring to livelihood for agriculture and farming to get back in shape," U.N. humanitarian operations spokesman Maurizio Giuliano told Reuters.
