The trend of scientific research analysis on climate change in Iran
Mahdi Hadi, Maryam Hashemkhani, Elnaz Iravani,
Volume 15, Issue 2 (8-2022)
Abstract
Background and Objective: Researchers investigate and identify the gaps and frequency of studies related to specific knowledge by using scientometrics. The purpose of this study was to analyze the trend of scientific research in the field of climate change in Iran.
Materials and Methods: All articles affiliated with Iran in the field of climate change have been cited in Scopus databases from 1991 to December 9, 2019, and were retrieved by using keywords like "climate change", "global warming", "global change", "climate variability", "greenhouse gas". The data were analyzed using R software.
Results: The total number of documents was 2253. The trend of document production in the field of climate change in Iran follows an increasing exponential trend. Iran's collaboration with other countries in the field of climate change studies was significant so around 25% of scientific productions have been produced jointly with other countries. Keywords analysis showed a greater frequency for keywords including “downscaling”, “energy”, “global warming” and “uncertainty”. However, despite the importance of issues such as “adaptation” and “vulnerability” concerning climate change in Iran, the frequency of these keywords in climate change studies in Iran is low.
Conclusion: Based on the results of this study and considering the importance of climate change and its effects on the country, also the importance of greenhouse gases including CO2, and the rank of Iran as the eighth country in the emission of these gases, it is recommended to pay more attention to issues such as “vulnerability”, “adaptability”, analysis of “greenhouse gases production”, “management of energy consumption” and the use of “renewable energies” in future studies.
 

The role of environmental health in the prevention and control of diseases related to environmental factors in Iran: a scientometric study
Ali Hamidi, Maryam Ravanipour, Masoumeh Ravanipour,
Volume 17, Issue 2 (9-2024)
Abstract
Background and Objective: Scientometrics is used to identify existing study gaps, discover the future research directions, investigate fundamental trends and implement the necessary policies in a specific field of knowledge. Considering the key role of environmental factors in the health trends and the varyingburden of diseases in the country, this study was conducted with the aim of performing scientometric analysis of the role of environmental health in the prevention and control of diseases related to environmental factors in Iran.
Materials and Methods: Bibliographic information related to scientific documents indexed in the Web of Science database until September 12, 2022, was analyzed and visualized using Citespace and Biblioshiny software.
Results: A total of 1,212 documents were retrieved. These documents were published in 629 sources with the participation of 8,461 authors. The average publication year of the documents was 2010. The top three ranks of organizational affiliations were as follows: Tehran University of Medical Sciences (747 documents), Isfahan University of Medical Sciences (436 documents), and Shahid Beheshti University of Medical Sciences (393 documents). Iran's cooperation network with other countries indicates substantial joint researchbetween Iran and the main countries in this network. Over time, the co-occurrence network of keywords has evolved from outcomes (such as cardiovascular diseases, cancers, etc.) to environmental exposure factors, especially air pollutants, heavy metals, and food-borne pathogens factors. Risk assessment has also been a category of interest in recent years.
Conclusion: Scientometric analysis showed that environmental health studies in prevention and control of diseases related to environmental factors in Iran are young and still progressing. In the early years, studies were mainly focused on diseases as an outcome, while in recent years, they have focused more on exposure factors or environmental pathogens. It is suggested that the future studies based on the retrieved keywords should be more mission-oriented and the priority of solving the problems of environmental pollutants affecting people's health in the country based on the extent and scope of the problems of each province should be considered by policy makers and researchers.
 

A scientometric analysis of publications on air pollution and respiratory diseases in Middle Eastern countries from 2003 to 2024
Afshin Hamdipour, Rasoul Zavaraqi, Hamideh Javadipour,
Volume 18, Issue 3 (12-2025)
Abstract
Background and Objective: Air pollution significantly exacerbates the burden of respiratory disease, particularly in the Middle East. This study aimed to conduct a scientometric analysis of publications on air pollution and respiratory diseases in Middle Eastern countries.
Materials and Methods: In this scientometric study, we analyzed 19811 documents on air pollution and respiratory diseases in Middle Eastern countries, published between (2003-2024) and retrieved from the WoS. Data visualization and analyses were conducted using VOSviewer and HistCite.
Results: The publication output showed a consistent upward trend, with an average annual growth rate of 11%. Environmental Science and Pollution Research was the leading journal (467 documents; 2.3%). Iran (28.3%), Turkey (27.1%), and Saudi Arabia (14.2%) collectively contributed more than 69% of the region’s scholarly output. Iran was identified as the most influential country in this field, with 111,930 global citations. Researchers from the Middle East collaborated with scholars from 166 countries, with the United States being the most frequent partner, accounting for 2,948 joint publications (14.9%). The study identified 60,814 contributing authors, forming twelve major collaboration networks, which facilitated the recognition of key research clusters and influential contributors. Keyword co-occurrence analysis identified seven dominant thematic clusters.
Conclusion: This study clarifies both qualitative and quantitative trends in Middle Eastern research on air pollution and respiratory diseases. To translate the region’s growing research capacity into lasting public health and policy impact, stakeholders should prioritize improving study quality, strengthening regional scientific collaboration, and establishing practical mechanisms to ensure that research findings are effectively incorporated into policy and practice.
