Annual rice production falls short of demand by 50 million tonnes. Annual growth in rice yield declined from 2.5 per cent during the green revolution (1960-70) to 1.1 per cent since 1980s, while global population grew by 1.4 per cent

90 per cent of rice is cultivated in Asia. But 55 per cent of Asians will be in urban areas by 2025, taking over some of the most fertile rice-growing areas

Rice consumption is already on the decline in south Asia and southeast Asia. China, India and southeast Asian countries have taken to diversified food like wheat, vegetables, meat, fruit and dairy products with rising income levels

Thailand and Vietnam have a major market in Africa, which accounts for 40 per cent of Thailand's total exports since 2000. 48 per cent of US export to Africa is through food aid programmes

Sub-Saharan Africa, where most of the new demand comes from, is getting poorer. Per capita consumption has doubled since 1970

People earning less than US $I a day rose in sub-Saharan Africa by 29 per cent during 1970-2000, but fell by 65 per cent in Asia

43 per cent of rice is cultivated in rainfed area and overlaps with concentrations of poor people. 75 per cent of the world's poorest depend on rice

Each hectare in sub-Saharan Africa with 16 per cent irrigation yields 25 per cent of one hectare in the developed world receiving 100 per cent irrigation
