The World Association of Agronomists, known as AMIA, was founded by representatives from thirty countries on September 8, 1994 in Santiago, Chile, as a result of the First World Congress of Professionals in Agronomy.

The World Association of Agronomists is a non-governmental, non-political, non-religious, and no-profit international organization, and managed by agronomists only.
The Association’s executive body is the General Secretariat which is chaired by an agronomist from the host country, appointed by its Management Board as nominated by the president of the Association.
