Science in Brazil, 2009-2013

December 2014

Brazil’s world share of science and social-science papers over a recent five-year period, ranked according to percentage of papers in each of 21 main fields indexed by Thomson Reuters. Also, Brazil’s relative citation impact compared to the world average in each field, in percentage terms. These figures are derived from Thomson Reuters InCites, a subset of the Web of Science.

Between 2009 and 2013, Thomson Reuters indexed 178,313 papers that listed at least one author address in Brazil. Of those papers, the highest percentage, by far, appeared in journals classified under the main heading of Agricultural Sciences, followed by Plant & Animal Science and Microbiology.

As the right-hand column shows, the citations-per-paper average, or impact, of Agricultural Sciences papers featuring Brazil-based authors was at 50% of the world average for the field (1.71 citations per paper for Brazil versus the world mark of 3.43 citations). In the other fields shown, Brazil is still moving towards parity with the world average in impact, with the exception of Physics, in which the nation exceeded the world figure by 5%. Relative impact was also comparatively strong in Engineering (11% below the world mark) and Mathematics (-12%).
