January 14, 1984 was an auspicious date for appropriate technology advocates and practitioners when SIBAT was conceptualized by nine (9) rural and Manila-based non-government organizations as a mechanism for coordination of their initiatives (i.e., particularly on research, training and cooperative development) in organic agriculture and appropriate technology.

The founding assembly took place on April 13-16, 1984. The First General Assembly held in Cebu City, formulated the orientation, direction and thrust of SIBAT. A Declaration of Principles was issued during this event and became the basis of unity of all SIBAT members.
