1 The Impact of African Science: A Bibliometric Analysis Scientometrics 102(2): 1241-1268 (2015) Hugo Confraria and Manuel Mira Godinho (ISEG, University of Lisbon,Portugal)

2 Motivation Plenty of bibliometric studies carried out for the developed countries and for the emerging economies (China etc.) …BUT… Until a couple of years ago no up-to-date bibliometric studies for Africa Is it acceptable / suitable to carry out such analysis for Africa? Declaration stemming from the 2003 African Ministerial Conference on Science and Technology commits to: – “develop and adopt common sets of indicators to benchmark our national and regional systems of innovation” (NEPAD, 2003).

3 Implicit questions How much should Africa invest in science? (trade-off…) How (and where) to invest in science? Objective: not to provide direct answers, but systematic data and analysis

4 Previous Studies Science in the continent  dismal state (Hassan, 2002). Little scientific co-authorship found between African countries (Narvaez-Berthelemot et al., 2002). Research production in Africa  highly skewed across nations and disciplinary areas (Uthman et al., 2007). Some fields of science (e.g. health sciences) are internationally oriented and tend to attract more international funds, partnerships, and opportunities to publish in international journals (Tjissen, 2007). Output sensitive to political instabilities, being the impact higher when the scientific communities are small (Waast et al., 2010).

5 Methodology - Databases Analysis of publications in WEB of Science Journals indexed by: Science Citation Index Expanded (SCI-EXPANDED); Social Sciences Citation Index (SSCI); Arts & Humanities Citation Index (A&HCI) The use of these DBs allows for easy international comparison Data covers 53 African countries, 2002 to 2011.

6 AnalysisIndicator Scientific productivity research output / GDP research output / population Specialization indexes RSI “Revealed Scientific Advantage Index” “Chi-square of sectoral specialization” Scientific Impact “Impact relative to subject area” Collaboration Network Analysis TOP10 countries that have more collaborations with each of the 13 African countries Regression WoS Pubs (02-11) X PCT Apps (02-11) Methodology – Metrics

15 All subject areas: Output vs. CXC (Impact), 2007-2011 world

16 Collaboration Network of the TOP 13 2007 and 2011

17 Scientific Impact versus Collaboration Intensity (2007-2011)

18 Log publications vs. log PCT applications (per 10^6 population, 2002-201)

19 Main Conclusions Take off from 2004 (2011 2.51% WoS) SA + Egypt + Nigeria + Tunisia driving output increase SA + Egypt > 50 % and top10 countries about 85% However smaller countries growing faster Docs/GDP – On world average Docs/POP – Much below world average Specialization mainly in Agricultural Sciences (+ Related areas: Environmental & Ecology and Plant & Animal Sciences) and some specific health sciences (Immunology, Microbiology)

20 Main Conclusions “Academic impact” Impact rising from 2002 to 2011 Impact of Mozambique, Zambia, Mali, Tanzania, Uganda, Malawi, Kenya > World average + IMPACT > Small scientific communities > High levels of specialization in few scientific disciplines > High levels of international collaboration > English language “Practical impact” PCT patents share below scientific share and declining Non linear dynamics between publication and patenting Science mainly related with education (capability building)
