rural extension, agricultural policy, sustainable developmentAbstract
Agricultural technical assistance is a public policy tool. This study analyzed, from a social science perspective, the international scientific literature on agricultural technical assistance, sustainable agricultural practices, and productive diversification. A quantitative, descriptive, and retrospective longitudinal design was used. A search in Scopus yielded 3,619 records; after excluding other document types, incomplete years, subject areas outside the social sciences, and duplicates—in accordance with the PRISMA 2020 protocol—the corpus consisted of 1,101 articles and reviews published between 1983 and 2025. The data were processed using Bibliometrix and Biblioshiny through performance indicators and scientific mapping. Output grew at an annual rate of 13.43%, and 76.8% of the documents were published since 2016. 35.88% involve international co-authorship. The United States, Ethiopia, and South Africa lead in output based on the country of the corresponding author; Africa accounts for 31.7% of these documents, and Latin America, 5.2%. Reference spectroscopy shows that the field draws on the theory of innovation diffusion and the economics of adoption. The thematic map identifies agroecology as a driving theme and adoption and climate change as core themes, while diversification does not constitute a theme in its own right. Research in this field has focused primarily on how technical assistance promotes the adoption of sustainable practices and has given less attention to its impact on crop and income diversification, which limits the evaluation of public programs.
