A groundbreaking scientometric analysis has illuminated the rising prominence of Indigenous Knowledge Systems (IKS), or IK, in higher education curricula worldwide, positioning it as a vital force for sustainable development. Published in the Journal of International Students on April 5, 2026, the study titled “Indigenous knowledge and curriculum internationalisation for sustainability. A decade of global scientometric analysis (2016–2025)” reveals a decade-long surge in research output, with IK transitioning from peripheral local practices to a globally networked domain integral to addressing climate challenges and advancing the United Nations Sustainable Development Goals (SDGs).

This shift is particularly pronounced in South Africa, where universities are at the forefront of weaving IK into teaching and research. The analysis of 173 Scopus-indexed publications shows steady growth accelerating post-2018, coinciding with SDG adoption. IK now underpins decolonised curricula, teacher training, and global citizenship education, fostering epistemic plurality—where diverse knowledge systems coexist to solve real-world problems like biodiversity loss and environmental degradation.

South Africa's Pioneering Role in IK Research

South African higher education institutions have emerged as key contributors to this global IK renaissance. The study highlights substantial increases from the Global South, including South Africa alongside Brazil, India, and Indonesia, signaling a rebalancing of epistemic power away from Western dominance. Universities such as the University of KwaZulu-Natal (UKZN), home to the African Institute in Indigenous Knowledge Systems (AIIKS), are leading efforts to document, preserve, and integrate IK into academic frameworks. AIIKS, approved as a research institute and UNESCO-recommended, focuses on traditional African knowledge for modern applications in health, agriculture, and ecology.

Similarly, North West University's Indigenous Knowledge Systems Centre pioneers IK research across Africa, exploring its applications in sustainable livelihoods. These institutions exemplify how SA universities are bridging traditional wisdom with contemporary science, contributing to SDG 4.7 (education for sustainable development) and SDG 13 (climate action). For instance, UKZN researchers have demonstrated IK's role in ecosystem management, using practices like controlled burning and polyculture to enhance soil fertility by up to 40% and boost crop yields by 20-60%.

Key Findings from the Scientometric Analysis

The study's methodology involved science-mapping tools on Scopus data, revealing thematic evolution from early biodiversity-focused work to sophisticated integrations in curriculum reform. Annual publication trends show IK's integration challenging Eurocentric models, with collaborations forming dense networks among Global South institutions. South Africa's output has grown significantly, reflecting policy support like the Department of Science and Innovation's (DSI) Indigenous Knowledge Systems Policy, which aims to stimulate IK's contribution to socio-economic development.

IK's value lies in its place-based, holistic approach: Zulu rotational cropping prevents soil depletion, San tracking informs biodiversity conservation, and Xhosa herbal medicine offers climate-resilient health solutions. These practices align with SDGs by promoting responsible consumption (SDG 12), zero hunger (SDG 2), and life on land (SDG 15). The analysis underscores IK's role in 'ontological shock' for international students, exposing them to diverse epistemologies for ethical sustainability engagement.

SA Universities Driving IK Integration in Curricula

In South African classrooms, IK integration is gaining traction. A case study from UKZN's Asheena Singh-Pillay and Andile Madlala examined Grade 8 Natural Sciences teaching in KwaZulu-Natal, where teachers incorporated IK agricultural practices like ibhuleki (controlled burning) and ubulongwe (organic dung fertilization). Using inquiry-based learning, storytelling, and visual aids, educators positioned IK as empirical science complementary to Western methods, enabling students to navigate multiple knowledge systems seamlessly.

At Stellenbosch University, IK informs wine science and ecology research, while Wits University's genomics projects incorporate San knowledge for benefit-sharing models. NWU's centre advances IK in teacher education, training educators to blend traditional and modern pedagogies. These efforts address decolonisation calls, with IK fostering cognitive justice—recognising non-Western knowledge as equally valid.

Challenges in Mainstreaming IK in SA Higher Education

Despite progress, challenges persist. The scientometric study notes asymmetries: Global North dominates publication volume due to better funding and infrastructure. In SA, tokenistic IK inclusion in curricula—often symbolic rather than structural—limits impact. Teachers require training in IK pedagogies, and policies like the Curriculum and Assessment Policy Statement (CAPS) need reform for authentic integration.

Resource gaps hinder digital preservation, vital for global networking. Community partnerships are essential but under-resourced, risking IK appropriation without benefiting originators. SA universities must prioritise open-access dissemination and North-South equity to amplify IK's voice.

Global Networking: SA's IK in International Collaborations

IK's global surge manifests in networked collaborations. SA universities partner with international bodies like UNESCO and the World Bank, integrating IK into SDG frameworks. UKZN's AIIKS collaborates continent-wide, while Univen hosts forums linking IK to bioeconomy and climate resilience. The study's collaboration maps show dense Global South networks, positioning SA as a hub for IK-driven sustainability.

This networking extends to curriculum internationalisation, where IK enriches exchange programs, preparing students for pluralistic worldviews. Examples include IK in UKZN's teacher training exported to African partners, enhancing regional sustainable development capacity.

Implications for Sustainable Development in South Africa

IK offers practical solutions for SA's challenges: drought-resistant farming from IK polycultures combats food insecurity; San fire management mitigates wildfires amid climate change; traditional medicines provide affordable healthcare. By embedding IK in higher ed, universities cultivate graduates who innovate at the science-IK nexus, driving bioeconomy growth estimated at R100 billion potential.

Government support via DSI's IKS Policy and NRF funding amplifies this. Universities like UKZN and NWU lead, but scaling requires policy alignment, funding, and community co-creation.

Stakeholder Perspectives and Case Studies

UKZN's Singh-Pillay emphasises teachers as 'cultural brokers', validating IK alongside science. NWU's centre director highlights IK's role in livelihoods sustainability. Case: In Pinetown schools, IK integration boosted student engagement, linking local practices to global SDGs.

• Inquiry-based community visits reveal IK's empirical basis.
• Storytelling transmits knowledge intergenerationally.
• Visual aids make IK accessible.
• Culture-science bridges foster pluralism.

Future Outlook: Pathways Forward for SA Higher Ed

The study calls for structural reforms: decolonised curricula, IK teacher training, and equitable collaborations. SA universities should invest in digital IK repositories, partner with communities for benefit-sharing, and advocate open-access. With DSI and NRF backing, IK can propel SA toward Viksit Bharat-like knowledge economy, blending tradition and innovation for resilient sustainability.

Prospects include IK-infused SDG research hubs, international IK exchanges, and policy embedding IK in national curricula. By championing IK, SA higher ed positions itself as a global leader in epistemic justice and sustainable futures.
