The foreign adviser, Iftekhar Ahmed Chowdhury, has urged the UN secretary general, Ban Ki-moon, to immediately establish a high- level task force to address the acute global food crisis. He made the appeal while chairing a ministerial meeting of LDCs on the eve of the inauguration of UNCTAD-XII in the Ghana's capital on Saturday. Iftekhar proposed that the task force, comprising eminent persons, should address long-term food security issues including those of agricultural productivity, grains trade, land utilisation and diversion for bio-fuels. He also suggested that the task force should submit its recommendations within three months, following which the secretary general should convene an international meeting to take appropriate action.
