||In developing countries, researchers with strong international links potentially act as a double-edge sword. On the one hand, local researchers with international links could strengthen the research base of an institution or country while, on the other hand, they could leave the research base vulnerable should they migrate. The study identified internationally linked authors in Uganda, East Africa, by applying individual-level bibliometrics to a dataset of 3,948 Ugandan authors from the Web of Science, for the period 2011–2015. The focus was on four overlapping groups of internationally linked authors: (1) Ugandan authors with an international co-author, (2) Uganda authors with a joint international affiliation, (3) Ugandan authors affiliated with an international organisation that has a local address, and (4) Ugandan authors affiliated with an international research partnership. The study showed that without the identified forms of international linkages, the Ugandan scholarly workforce would reduce to 14% of its current size. Moreover, 74% of Ugandan authors without any international links had co-authored articles with Ugandan authors who are linked internationally. Although the extent of both international and national mobility associated with internationally linked authors seem low, benchmarking against comparative figures for other countries in sub-Saharan Africa is required.
