The National Bank for Agriculture and Rural Development (Nabard) will raise in a month funds for the Rs.20,000 crore dedicated long-term irrigation fund announced in this year's budget, its Chairman Harsh Kumar Bhanwala has said. Elaborating on the plans for the fund mop up, Bhanwala said that Nabard will raise the funds in several tranches under two types of bonds. One type of bond will be in which the Centre will take the liability for repayment, and the other in which Nabard will bear the obligation to repay the bonds. Of the targeted funds mop up of close to Rs.20,000 crore, the water resources ministry will bring in Rs.1,500 crore (budgetary allocation), the bonds for which the Centre will take the repayment obligation will amount to about Rs. 6,300 crore, and the balance amount of about Rs.12,000-13,000 crore will be directly raised by Nabard under its own books, Bhanwala said
