Culturally Grounded Co-Design for Sustainable Technology: A Conceptual Analysis Illustrated by the O-Waste Project in the Gambia

Implementing technological change in rural or culturally distinct settings requires moving beyond the modernization bias that treats Western technical solutions as universally applicable. This article develops a process-based reflection on culturally grounded co-design for sustainable technology, drawing on social design, just transition principles, and appropriate technology. Rather than evaluating final project outcomes, the article examines how technology and social organization can be approached as context-specific practices that must be negotiated, adapted, and maintained with local actors. The discussion is informed by the O-Waste Project in The Gambia, which is used as an illustrative case to examine the role of local councils, women’s organizations, market committees, and implementing partners in shaping technological adoption. By emphasizing vernacular knowledge, locally maintainable systems, and participatory decision-making, the article argues that sustainable innovation depends on technical performance as well as cultural legitimacy, institutional trust, and procedural justice. The analysis suggests that development in diverse cultural contexts requires a careful balance between external technical expertise and community appropriation. The O-Waste case therefore offers process-based insights into how sustainable technologies can be introduced without reducing local communities to passive recipients of modernization.
