Science in South Africa, 1998-2002

South Africa's world share of science and social-science papers over a recent five-year period, expressed as a percentage of papers in each of 21 fields in the ISI database. Also, South Africa's relative citation impact compared to the world average in each field, in percentage terms.

     Field

Percentage of papers from South Africa

Relative impact compared to world
Plant & Animal Science 1.59 -35
Ecology/Environmental  1.16 -25
Geosciences  1.13 -27
Space Science 0.91 -19
Education  0.80 -33
Microbiology 0.64 -25
Social Sciences 0.61 -15
Agricultural Sciences 0.53 -8

**<---  South Africa, 1998-2002's overall percent share, all fields: 0.50 --->**
Psychology/Psychiatry 0.49 -48
Economics & Business 0.47 -73
Clinical Medicine 0.44 -20
Pharmacology  0.44 -30
Immunology  0.43 -1
Mathematics  0.41 -21
Biology & Biochemistry 0.36 -41
Chemistry  0.33 -40
Engineering  0.23 -32
Materials Science 0.30 -15
Molecular Biology 0.28 -48
Physics 0.26 -20
Computer Science 0.24 -46
Neurosciences  0.19 -46

Between 1998 and 2002, ISI indexed 18,152 papers that listed at least one author address in South Africa. Of those papers, the highest percentage appeared in journals classified under the heading of plant & animal sciences. As the right-hand column shows, the citations-per-paper average for South African research in plant & animal sciences was 35% below the world mark for that field (1.76 cites per paper for South Africa, versus the world average of 2.72 cites per paper). While the relative impact of South African research has yet to attain the world average in any of the fields shown, performance was comparatively strong in immunology, agricultural sciences, materials science, and social sciences.
