A scientist’s position in the ranking is determined by their D-index (Discipline H-index), a metric that isolates a researcher's impact within a specific discipline by including only papers and citation metrics relevant to that field. This discipline-focused approach guarantees an accurate reflection of scholarly influence within Environmental Sciences.
Scope and Criteria of the Ranking
This ranking is based on the examination of 279,971 scientist profiles identified across a diverse array of bibliometric data sources, encompassing all scientific disciplines. Specifically, 8 scientists within the Environmental Sciences discipline in Cyprus were evaluated for this edition.
To qualify for inclusion in the ranking, researchers were required to meet stringent criteria. First, their D-index had to be at least 30, reflecting significant scholarly output and impact within the field. Second, a majority of their tier publications needed to be concentrated in Environmental Sciences, ensuring disciplinary relevance. Furthermore, recognition through awards and achievements in Environmental Sciences was factored in as an additional qualitative measure.
The threshold for the D-index is dynamically adjusted in increments of 10 depending on the estimated total number of scholars within each discipline, while maintaining an inclusion of the top 1% of leading experts. An additional qualifier mandates that the proximity between a scientist’s general H-index and their D-index remains within 30% or less, maintaining alignment between overall and discipline-specific research impact.
Verification and Validation Practices
The team behind this ranking is keenly aware that raw bibliometric data alone cannot serve as an absolute indicator of a researcher’s scholarly contributions. To uphold the highest standards of accuracy and credibility, all scientist profiles were manually verified and cross-correlated against publications indexed in a broad range of trustworthy sources. This meticulous validation process safeguards against inaccuracies and ensures that data quality meets rigorous academic standards.
Although publication counts in prominent journals and conference proceedings do not influence a researcher’s ranking position, they provide valuable secondary signals of scientific contribution within a specific area of research.
The final ranking positions were established by leveraging each researcher’s D-index based on meticulously gathered data from OpenAlex and CrossRef. These sources are acknowledged as the most reliable and comprehensive bibliometric databases, further reinforcing the ranking’s authority.
