The Surge in Brazilian Scientific Output and Its Pressures
Brazil has witnessed a remarkable expansion in its scientific publications over the past two decades, driven by national evaluation systems and the demands of graduate education. Institutions such as the University of São Paulo (USP), the State University of Campinas (Unicamp), and the Oswaldo Cruz Foundation (Fiocruz) have contributed significantly to this growth. The Coordination for the Improvement of Higher Education Personnel (CAPES) and the National Council for Scientific and Technological Development (CNPq) have played central roles in shaping incentives for researchers at federal and state universities across the country.
Recent data indicate that Brazilian researchers published approximately 69,656 articles in 2023, followed by a rebound to around 73,220 articles in 2024, representing a 4.5 percent increase. This recovery comes after consecutive years of decline linked to reduced federal investment in science and technology. Funding for CNPq and the National Fund for Scientific and Technological Development (FNDCT) has faced structural challenges, with real-term budgets falling substantially since 2013. These dynamics have intensified the pressure on academics to publish, particularly in graduate programs evaluated by CAPES.
Evaluation Systems Fueling Publication Growth
The CAPES evaluation of graduate programs has historically emphasized publication volume through the Qualis journal classification system. This framework influenced scholarship allocation, program rankings, and career progression for faculty at institutions nationwide. Researchers often targeted higher-strata journals to secure productivity grants from CNPq and advance in their careers at universities in São Paulo, Rio de Janeiro, Minas Gerais, and other states.
Recent reforms by CAPES signal a shift away from journal-centric metrics toward assessing the quality and societal impact of individual articles. This change aims to address some distortions created by the previous model, which encouraged quantity over depth. State research foundations such as FAPESP in São Paulo have also supported open-access initiatives through platforms like SciELO, broadening visibility for Brazilian scholarship.
Strains on the Peer Review Process
The rapid increase in submissions has placed unprecedented strain on the peer review system. Reviewers at Brazilian journals and international outlets report higher refusal rates and longer turnaround times. Editors at SciELO-indexed publications and university presses have noted difficulties in securing qualified reviewers, especially in specialized fields where expertise is limited.
Global trends in manipulated peer review and paper mills have affected Brazilian output as well. Studies of retractions in the SciELO Brazil collection highlight issues such as plagiarism, data fabrication, and fake reviewer suggestions. These problems have led to retractions involving researchers affiliated with public universities and funded projects from CNPq and FAPESP. The rise of predatory outlets promising rapid publication has further complicated the landscape for early-career academics seeking to meet evaluation criteria.
Impacts on Universities and Researchers
At federal universities and state institutions, the publish-or-perish culture has influenced hiring, promotion, and funding decisions. Early-career researchers, including postdoctoral fellows supported by CAPES and CNPq programs, face delays that can affect contract renewals and grant applications. Brain drain concerns have emerged as inconsistent funding cycles prompt some talent to seek opportunities abroad.
Graduate students in programs evaluated by CAPES often prioritize publication in indexed journals, sometimes at the expense of thorough methodology or broader societal relevance. This dynamic has sparked discussions among rectors and academic associations about balancing quantity with integrity.

Retractions and Integrity Challenges
Analyses of retracted articles from Brazilian authors reveal patterns of misconduct, including duplication and image manipulation. While not unique to Brazil, the concentration in certain open-access journals indexed by SciELO has prompted calls for stronger oversight. Funding agencies have responded with updated guidelines on research integrity, emphasizing transparency in authorship and data management.
University ethics committees and graduate program coordinators are increasingly involved in training on responsible conduct. Institutions like USP and Unicamp have implemented workshops and policies to mitigate risks associated with high-pressure publication environments.
Emerging Solutions and Reforms
Brazilian stakeholders are exploring open peer review models and greater use of preprint servers to alleviate bottlenecks. SciELO has promoted initiatives for open science, including transparent review processes. Collaborative efforts between CAPES, CNPq, and state foundations aim to diversify evaluation criteria beyond traditional bibliometrics.
Artificial intelligence tools are being piloted for initial manuscript screening at some journals, though human oversight remains essential. Discussions at national forums emphasize the need for sustainable funding to support both research and editorial infrastructure at universities.
Perspectives from Key Institutions
Leaders at Fiocruz and other research-intensive centers stress the importance of maintaining Brazil's position in global science while safeguarding quality. International partnerships, including transformative agreements with publishers for open-access publishing, offer pathways to increase visibility without compromising standards.
Faculty associations and student representatives have advocated for workload adjustments and better support for reviewers, many of whom are themselves active researchers balancing teaching and administrative duties at Brazilian universities.
Broader Implications for Higher Education
The intersection of publication growth and peer review challenges affects doctoral training, postdoctoral opportunities, and the overall research ecosystem. Universities are adapting by investing in research integrity offices and revising internal promotion guidelines to value diverse contributions beyond journal articles.
These developments underscore the need for systemic approaches that align incentives with long-term scientific advancement, particularly in fields critical to national priorities such as public health, agriculture, and environmental sustainability.

Future Outlook and Recommendations
Looking ahead, sustained investment in science funding and editorial capacity will be crucial. Reforms to evaluation frameworks by CAPES and enhanced collaboration through SciELO could help restore balance. International best practices in open science and responsible metrics offer models adaptable to the Brazilian context.
Stakeholders across the higher education sector continue to engage in dialogue to ensure that the expansion of scientific output translates into credible, impactful knowledge. Continued attention to these issues will support Brazil's role in the global research community.
