The forecast indicates a gradual decline in Brazil's share of scientific publications among the world's 10% top-cited in chemical engineering from 3.92% in 2024 to 3.52% by 2028. This denotes a consistent downtrend from the present (2024) level. Given the historical context, the year-on-year decline is persistent, with the compound annual growth rate (CAGR) depicting a negative trajectory over the last five years.

Future trends to watch for:

Strengthening collaborative efforts internationally to enhance citation impact.
Increased investment in research infrastructure and funding to boost research quality.
Focused policy initiatives to support innovation and high-impact research outputs.
