This chapter introduces digital communities of practice as a means of operationalizing and expanding the exercise of the human right to knowledge, positioning this right as essential for advancing the Sustainable Development Goals amid the global spread of the Information Age and the current upheavals in international development. As digital technologies increasingly shape economies, communication, and development strategies, access to life-sustaining information remains unequally distributed across linguistic, geographic, and socioeconomic lines. Framing knowledge as a public good and a foundational right, this chapter critically examines how barriers to accessibility, usability, and convenience disproportionately affect the world’s most marginalized populations. Arguing for producer-side interventions, this chapter outlines how knowledge producers—through strategies such as language localization, culturally responsive design, and adaptive learning systems—can ensure that scientifically grounded, contextually relevant information reaches those most in need. Drawing on examples such as Scientific Animations Without Borders (SAWBO), this chapter demonstrates how digital communities of practice—peer-driven, scalable, and rooted in formal, informal, and non-formal learning—can empower people to access, adapt, and apply information aligned with the Sustainable Development Goals (SDGs). Ultimately, this chapter contends that enabling the exercise of the right to knowledge requires not only technological infrastructure but also a moral and institutional commitment to epistemic justice, particularly as it pertains to digital equity and local agency.
