Food prices are on the rise and not only in India. The increase has been sharper still in in other Asian counties, such as Thailand, the Philippines, Indonesia and Myanmar. The continent is paying for its neglect of agricultural research and irrigation. There has neen a dwindling of prime land and shrinkage of water supplies owing to industrialisation. The UN's Economic Commission for Asia and the Pacific has stated that a boost in farm productivity is the only way out of the crisis. India urgently needs another Green Revolution. The government of Ms Arroyo in the Philippines is under threat from the opposition over the spectre of hunger. The situation may well get replicated in India if people feel that the government has failed to deliver. ~ Yours, etc., R Narayanan, Ghaziabad, 1 April. (Letters)
