Patterns of adoption of improved rice varieties and farm-level impacts in stress-prone rainfed areas in South Asia
Widespread and persistent poverty in Asia is a longstanding problem, particularly in rainfed ecosystems. Rice is dominant in these areas because it is the only crop that can be grown in the wet season. As a result, it is the principal source of the rural population's food, employment, and income. Rice yields in these rainfed ecosystems- home to 100 million farm households that plant a total of 60 million hectares-remain low (1.5-2.5 tons/ha) and unstable because of two perennial wraths of nature, drought and flooding, which with looming climate change will only become worse. Compounding this problem are poor soils that pervade many rice-growing environments.
