It is a known fact that historical resource management has existed without Western knowledge in Africa. Then, local, Indigenous, and traditional communities have adequate stewardship and control of marine blue resources without overexploitation, overfishing, or pollution issues. Hence, this era is called the era of traditional sustainability values. However, the increasing technologies derived from Western knowledge of the blue resources have culled the mismanagement of these resources. Knowing that it is still possible to achieve sustainable blue economy practices globally, there is a need to harness the power of Indigenous and Western knowledge and practices. Hence, this chapter aims to examine various Indigenous conservation approaches and how they are integrated with Western resource management techniques to promote inclusivity in advancing a sustainable blue economy in Africa. This situation could be achieved by synergizing traditional Indigenous knowledge with Western scientific principles to solve complex problems and ensure participation in decision-making and policymaking. Integrating traditional ecological knowledge is pivotal for preserving cultural heritage and fostering ecologically sound practices. On the other hand, it is known that using Western traits like advanced technologies and open government systems can make blue economy projects more effective and scalable. This chapter emphasizes the need for a balanced and inclusive approach that respects Indigenous insights while leveraging global innovations to address local needs and broader sustainability objectives.
