Food insecurity, income inequality, and the changing comparative advantage in world agriculture

I would like to argue in this article that in the process of economic development in land-poor countries in Asia, agriculture faces three distinctly different problems: food insecurity, sectoral income inequality, and the declining food self-sufficiency associated with the declining comparative advantage in agriculture at the high-income stage. Massive imports of food grains to Asia, if they occur, will aggravate the world food shortage, which will have significant implications for the poverty incidence in the world. I argue that in order to avoid such a tragedy, Asia should expand farm size to reduce labor cost by adopting large-scale mechanization, sub-Saharan Africa should realize a green revolution in grain production, and Latin America should further expand its grain production capacity.
