Indigenous technical knowledge (ITK) plays a vital role in sustainable agriculture, offering eco-friendly practices and methods honed over generations. This chapter explores the integration of ITK with modern agricultural techniques to enhance crop production and environmental sustainability. It highlights how ITK, including practices like crop rotation, intercropping, and natural pest management, supports soil health, reduces chemical dependency, and promotes biodiversity. The historical context of ITK demonstrates its evolution from folklore to recognized scientific knowledge, emphasizing its relevance in contemporary farming. The chapter also examines successful case studies from various regions, illustrating the benefits of combining traditional wisdom with modern technologies. Despite its value, ITK faces challenges such as modernization and environmental degradation, which threaten its preservation. Strategies for revitalizing and integrating ITK into current agricultural systems are proposed to ensure its continued contribution to sustainable development.
