This document discusses IS innovation for agriculture advisory services in Ghana. It finds that IS innovations have progressed through three generations: (1) providing basic access to information and organizing existing resources, (2) increasing interaction through multimedia and modifying actions through single-loop learning, and (3) enabling information and knowledge sharing through double-loop learning. Key enabling and constraining factors include infrastructure, organizational norms, and traditional oral culture. Sample first generation IS artifacts include GIFEC's CICs and GAINS' question and answer system, while second generation examples are Esoko Scout and third generation is Talking Book knowledge exchanges.
