Africa's research publishing landscape: examining journals, publishers, and the infrastructure behind them.

Background: Africa's research publishing sector is growing but remains largely fragmented and under-resourced, posing major barriers to the visibility, accessibility, and global integration of African research. Methods: This paper presents a continent-wide mapping of Africa's research publishing ecosystem, drawing on five integrated datasets covering 1,169 publishers and 1,790 journals to assess the scale, thematic content, linguistic diversity, and the degree of openness characterising the African publishing landscape. Results: The analysis reveals that the majority of journals are published by single-journal entities embedded within universities, learned societies, and research institutes. While this decentralised model allows for locally driven publishing and alignment with national research priorities, it is often constrained by limited infrastructure, inconsistent metadata practices, and lack of professional publishing support. Geographically, publishing activity is concentrated in a few countries, most notably Egypt, Nigeria, and South Africa - reflecting disparities in research investment and infrastructure across the continent. Disciplinary patterns reveal a strong emphasis on the social sciences and humanities, shaped by post-independence academic development and limited commercial interest in these fields. The predominance of English in journal publishing enhances global visibility but risks marginalising non-Anglophone scholarship. The study also explores the increasing role of commercial publishers in improving visibility and editorial standards, while raising concerns about data control, sustainability, and long-term ownership of African research outputs. Conclusion: The paper concludes by highlighting the urgent need for coordinated, African-led investments in shared infrastructure, multilingual publishing strategies, and national indexing systems. These efforts are essential to enhance research equity, reduce dependency on external platforms, and ensure African knowledge systems are robust, inclusive, and visible in a rapidly evolving global publishing environment.
