The study was conducted in Lindi (Nachingwea district) and Mtwara (Masasi district) to investigate and document existing indigenous knowledge practices on management of agro-biodiversity and show how Nonaka and Konnos' 1998 KM model (Socialization, Externalization, Combination and Internalization (SECI)) can be applied to manage indigenous knowledge related to agro-biodiversity in local communities. Combined with Adapted Sustainable Livelihood model, the study also sought to investigate how such knowledge contributes to livelihoods of local communities.
