MADRID: The ADB pledged $2.5 billion in emergency aid and loans in Asian nations hit hardest by soaring food costs as finance chiefs agreed on Tuesday to boost farm output as a long term solution to the crisis.

After four days of talks governments remained split on whether they should use export bans and market intervention to ensure one billion poor Asians living on less than $2 a day do not slip back into hunger and malnutrition.

Finance chiefs called on the Asian Development Bank to take an active role in stabilising surging food prices in a region that is home to two thirds of the world’s poor and risks civil unrest after wheat and rice prices doubled in the last year. ADB President Haruhiko Kuroda said the Manila-based bank stood ready to act.

“I am pleased to announce that ADB will provide $500 million as immediate budgetary support to the hardest hit countries so that they can bring food to the tables of the vulnerable, poor and needy,” he said. But Kuroda said the best long term solution to painful price spikes was through boosting agricultural output, adding that the bank would double lending to agricultural and natural resource and infrastructure projects to $2 billion in 2009.
