This paper examines the impact of the 1993 North American Free Trade Agreement on Mexican agriculture. It begins by noting the benefits of the agreement for industry and the concentration of those benefits in northern and central Mexico. Agricultural exporters in the north (tomatoes, roses, citrus fruits) adjacent to California have also benefited. However, corn and sorghum the two largest domestic crops and the principle crops in the 'agri-subsistence' south (including Chiapas), have all faltered under freer trade. 14 pgs.
