Science in Brazil, 2002-06

Brazil'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 Thomson Scientific database. Also, Brazil's relative citation impact compared to the world average in each field, in percentage terms.

Between 2002 and 2006, Thomson Scientific indexed 70,003 papers that listed at least one author address in Brazil. Of those papers, the highest percentage appeared in journals categorized under the heading of agricultural sciences, followed by plant & animal sciences and microbiology. As the right-hand column indicates, Brazil's impact average in agricultural sciences was 46% below the world mark (1.47 cites per paper for Brazil, versus the world average of 2.74 cites). On the other hand, the nation's relative-impact performance was comparatively strong in physics, ecology/environmental sciences, mathematics, geosciences, and engineering.
