KABUL (AFP) - Millions of Afghans are finding it "problematic" to meet their basic food needs with prices of the staple food, wheat, doubling in some areas over recent months, the World Food Programme said Thursday. Imports are being squeezed and there are early indications that low snowfalls and rain could result in a poor domestic wheat crop, WFP Asia director Anthony Banbury told reporters. "The WFP assessment is that right now meeting basic food needs is extremely problematic for millions of Afghans," Banbury said, wrapping up a visit to the country. Inflation in Afghanistan was 22 percent in February, including 30 percent for food and between 50 and 100 percent for wheat depending on the area of the country, he said. While many Afghans could cope with the price hike, the hardest hit were the poorest, some of whom had to spend 70 percent of their income on food, he said. Banbury commended the Afghan government for being one of the first in the world to taken action on rising global food prices by issuing an appeal in January for 79 million dollars in aid for food. WFP's portion of this 77 million dollars is being used to support 2.5 million Afghans in a programme due to end in July, he said. The government has set aside a separate 50 million dollars to buy in food. The future need for help would depend on agriculture production, global supply, commercial imports and other issues. Banbury stressed though: "The solution to the food security problem is not food aid. It is investment in agriculture, it's better roads, more developed markets, good trade policies." He urged Afghanistan and its allies to come up with a "comprehensive strategy" to meeting its food needs. The largely rural country, where most people subsist on agriculture, is regularly struck by drought. Decades of war have meanwhile destroyed its infrastructure, and efforts to rebuild are hampered by an extremist insurgency.
