Since the 1970s green revolution, agricultural production has continued to rise, but not to benefit the hungry. Half of India's children aged under five suffer from malnutrition, and the rate remained stable between 1999 and 2006 despite the economic growth in those years. India is the world's 11th largest economic power but still has more people in poverty than sub-Saharan Africa, even though it has not suffered from civil wars and political crises.
