A scientist’s position within this ranking is determined by their Discipline H-index, hereafter referred to as the D-index. This index exclusively considers publications and citation metrics that pertain to the specific discipline under examination — in this case, Environmental Sciences. This targeted approach ensures a precise and relevant assessment of each researcher’s impact within their specialized area of expertise.
Scope of Research and Eligibility Criteria
Our evaluation process examined a total of 279,971 scientist profiles drawn from diverse bibliometric resources covering all scientific disciplines. Within that broad cohort, 36 scientists focused specifically on Environmental Sciences in Israel were identified and subjected to detailed analysis.
To qualify for inclusion in this ranking, a scientist was required to have a D-index of at least 30, with the majority of their top-tier publications concentrated in Environmental Sciences. Additionally, a researcher’s documented awards and achievements within this field were considered to provide further context on their scholarly contributions.
The threshold D-index value is dynamically set in increments of 10 according to the estimated total number of researchers present in each discipline, ensuring that the ranking consistently encompasses the top 1% of leading scholars. Furthermore, to maintain disciplinary relevance, we applied a criterion that a researcher’s general H-index and D-index should be within 30% of each other, thereby guaranteeing a close alignment between overall scholarly output and specific disciplinary impact.
Verification Practices and Methodological Transparency
At Research.com, we recognize that raw bibliometric data alone cannot serve as an absolute or definitive measure of scholarly output or impact. Consequently, every scientist profile included in this ranking underwent manual verification and was cross-checked against a wide range of trusted publication sources. This rigorous verification process adds an essential layer of quality assurance to the ranking.
While not factored directly into ranking positions, the number of papers published in prominent journals and esteemed conference proceedings is considered a valuable secondary indicator of a researcher’s scientific influence within Environmental Sciences. This supplementary signal provides additional context regarding the breadth and quality of scholarly contributions.
It is important to emphasize that ranking positions are established exclusively using each researcher’s D-index based on data aggregated from OpenAlex and CrossRef. These two databases are among the most prominent and well-curated bibliometric tools available to the global research community, reinforcing the credibility and robustness of this ranking.
