International collaboration clusters in Africa
Jonathan Adams, Karen Gurney, Daniel Hook, Loet Leydesdorff
TL;DR
The paper asks whether African research collaboration follows the uniform global pattern described elsewhere. It analyzes African collaboration links and finds that geography, shared culture and especially language help distinguish patterns that are not captured by a single network. The authors argue that understanding these bottom-up factors matters for research policy and management.
Problem
The paper asks whether Africa shares the uniform, generic research-collaboration pattern perceived elsewhere or exhibits more subtle influences.

Abstract
from arXiv · showhide
Recent discussion about the increase in international research collaboration suggests a comprehensive global network centred around a group of core countries and driven by generic socio-economic factors where the global system influences all national and institutional outcomes. In counterpoint, we demonstrate that the collaboration pattern for countries in Africa is far from universal. Instead, it exhibits layers of internal clusters and external links that are explained not by monotypic global influences but by regional geography and, perhaps even more strongly, by history, culture and language. Analysis of these bottom-up, subjective, human factors is required in order to provide the fuller explanation useful for policy and management purposes.
Introduction
Studies describe growing international research collaboration and a global network centred on core countries, but that network alone does not explain African patterns. This paper examines how regional geography and human factors such as history, culture and language shape collaboration in Africa.
Introduction
- Prior work describes an intensifying global collaboration network that reinforces a core of fourteen cooperative countries and may disadvantage peripheral countries.Source: Introduction · p. 1
- The paper contests the global network as a sufficient explanation, arguing that facilities and cooperative programmes also matter and that history, culture and language influence collaboration through personal preference.The authors accept the global meta-pattern while emphasizing agents and human influences beyond strategic logic.Source: Introduction · pp. 1–2
- Africa’s diversity and research-base challenges, including limited internet access outside North Africa, motivate the need for international research partners.Source: Introduction · p. 2
- The study asks whether Africa shares the uniform collaboration pattern reported elsewhere or instead exhibits more subtle influences.Source: Introduction · p. 2
Methods
The study analyzes African research publications and country-level co-authorship links from 2000 to 2012, using publication counts rather than researcher counts to measure collaboration.
Methods
- The dataset covers publications with at least one address in a UN-defined African country from 2000–2012 and includes GDP data for countries with publication records.Source: Methods · p. 2
- Volume and subject analyses use Thomson Reuters National Science Indicators, while collaboration analyses use Research Performance Profiles in InCites and include articles, notes and reviews.Source: Methods · p. 2
- Collaboration counts treat each co-authored paper as one link between every represented country pair, rather than counting participating researchers.A paper involving Ghana, Nigeria and Kenya contributes one link for each country pair.Source: Methods · p. 2
Results
African research output and domestic publication counts grew, but output is concentrated in a few countries and collaboration patterns vary across partners and regions. The analyses also identify differences in publication productivity relative to GDP and use complementary visualizations to represent collaboration links.
Results
- Africa’s indexed research output rose from 13,271 publications in 2000 to over 35,000 in 2012 (34,528 catalogued at Dec 15, 2012).Source: Results · p. 2
- Wholly African articles and reviews doubled from 6,319 to 12,089, although their share of total research-paper output fell from 54% to 42%; the share that was substantive research papers declined from 88% to 82.6%.The authors attribute the latter decline to more proceedings papers and other contributions authored within Africa.Source: Results · pp. 2–3
- Publication output was concentrated in South Africa, Egypt and Nigeria, with marked regional differences in the leading countries’ totals.Since 2000, South Africa produced over 95,000 publications versus Tanzania’s just over 6,300; Egypt produced nearly 58,000, more than twice Tunisia’s total, and Nigeria exceeded 20,000 versus Kenya’s roughly 12,800.Source: Results · p. 3
- South Africa’s world-publication shares were highest in Plant & Animal Science (1.55%), Environment/Ecology (1.29%) and Geosciences (1.13%).The passage relates these fields to natural resources, climate change and mineral richness.Source: Results · p. 3
- Comparing publication output with GDP identifies Tunisia and Malawi as relative productivity leaders, while Nigeria produces less research than expected given its economy.Zimbabwe’s high publications-per-unit-GDP result is described as anomalous because it retains a legacy research base despite a collapsing economy and very low current GDP; the authors say a productivity gap also applies to several other countries.Source: Results · pp. 3–4
- Egypt–Saudi Arabia co-authorship rose from 100 papers (4% of Egypt’s output) in 2002 to over 1000 (15%) in 2011, with only a small fraction also including the USA.The authors characterize this axis as regionally, rather than globally, driven.Source: Results · p. 4
- France’s 31,421 co-authorships were concentrated in North Africa, led by Tunisia (7,400 23.6%), while the USA and UK collaborated more diversely across African countries.The UK had particularly strong links with the Gambia and Malawi; Saudi Arabia’s collaboration was almost entirely with North Africa, especially Egypt (4,939 joint publications).Source: Results · p. 4
- For six key African research economies, the study analyzes links with the USA, UK and three other frequent partners, and visualizes collaboration using a five-papers-per-year threshold over a recent five-year period.The threshold excludes countries with too little recent collaboration; a grouping algorithm places strongly cross-linked countries near one another, complemented by a more complete but more complex 2011 Africa network map.Source: Results · p. 4
Discussion
African research collaboration forms diverse international and intra-African links rather than one uniform network. Geography, shared culture, and especially language help explain this pattern, alongside global connections.
Discussion
- African research output is growing but remains small relative to established economies, and the paper argues that bottom-up factors are needed for policy-relevant performance analysis.The discussion also anticipates continued benefit from external support and collaboration.Source: Discussion · p. 5
- External collaboration varies by country: France ranks second after the USA, while the UK is the most frequent collaborator with other African countries; many links involve targeted health and food programmes.French links concentrate in North-West and central West Africa; UK examples include Malawi and Gambia.Source: Discussion · p. 5
- Egypt and Saudi Arabia have an exceptionally strong direct link associated with support for regional research-capacity growth in the Arabian Middle East.Source: Discussion · p. 5
- At a threshold of interaction strength, no single African research network emerges; collaboration reflects geography, shared culture, and especially language.The analysis presents diverse international and intra-African links rather than one uniform pattern.Source: Discussion · pp. 4–5
- North African countries form a marked, relatively prolific group linked by shared language and culture, but do little research with the rest of Africa beyond Egypt–South Africa.Source: Discussion · p. 5
- SADC does not emerge as one research network: it is split between the Kenya–Nigeria-linked group and a South Africa-centered group that includes Sudan and Gabon.Source: Discussion · p. 6
- Nigeria and South Africa are strong cross-continent nodes, with Kenya helping link African groups to global networks.Nigeria connects Anglophone networks, West African neighbours, and South Africa; South Africa has links into other groups.Source: Discussion · p. 6
- China and Brazil collaborate only weakly with Africa; Nigeria has some collaboration with China but has yet to realize a proposed opportunity to extend links to Brazil.Source: Discussion · p. 6
