Consequently, the irrigated and the high rainfall lowland environments became the primary source of food supply for Asia's escalating population. The emergence of the rice-wheat system in South Asia as the most important source of food supply, is a testament to the success of the Green revolution in wheat and rice. Recent signs indicate, however, a slow down in productivity growth of the primary cereals, rice and wheat, especially in the intensively cultivated lowlands of Asia, and particularly in the intensively cultivated rice-wheat zones of South Asia. Slackening of infrastructure and research investments and reduced policy support partly explain the sluggish growth. This pa...
