In developing countries, structural transformation started much later, mostly in the 1900s. The structural transformation of the agricultural sector has been characterized by the relative decline of basic agriculture; the rising importance of agribusiness, which includes the value added for agro-related industries and for agricultural trade and distribution services; as well as the growing share of high-value agricultural products in international trade with respect to traditional exports.
Agricultural structural transformation has been shaped by three interrelated processes: improvements in productivity; change in composition in production; and change in mode of commercialization.
