This externalisation process involves the articulation of farmers' hidden tacit knowledge into explicit knowledge. The study found that farmers externalised their tacit knowledge into explicit knowledge although it was practiced at a very low rate. The present findings showed that few (13.3%; 24) farmers converted their indigenous tacit knowledge into explicit forms which included written formats (87.5%; 21), carvings (16.7%; 4) and still pictures (7.4%; 2). Carvings included locally made traps for controlling plant pests, utensils, toys, ornaments and drawings on clay pots, hand mills and pestles. Poor recognition of IK and lack of a knowledge sharing culture may have limited farmers in externalising their tacit knowledge into explicit knowledge in the local communities.
