RESUMO
Traditional knowledge has played a significant role in the healthcare systems in countries of the African Region for centuries. Traditional medicines are presently used by nearly 80of the population. Owing to the global resurgence in the use of natural products and the advent of the biotechnological industry; traditional knowledge is increasingly becoming a source of modern drug development and biotechnological inventions. Despite the important role of traditional knowledge; traditional communities are unable to protect their knowledge through the existing intellectual property system owing to the failure of the knowledge to satisfy the requirements for intellectual property protection; incompatibility in most cases between the traditional knowledge concepts and intellectual property as well as the prohibitive costs involved in patent registration. Studies conducted recently and the outcomes of global debates have suggested some policy and legal approaches that can be used to effectively protect traditional knowledge; including traditional medicine. This paper discusses conceptsof traditional knowledge and provides policy and legal measures that have been developed at the international and regional levels for the protection and utilization of traditional knowledge for the benefit of the knowledge holders and society at large
