Scientific production on environmental education: a bibliometric analysis

The study presents a bibliometric analysis of scientific production on environmental education, using the VOSviewer software to map collaboration between authors and countries, as well as the co-occurrence of keywords. A total of 3,319 works published between 1996 and 2020 were analyzed, focusing on interdisciplinary and multidisciplinary collaboration. The analysis revealed a low level of collaboration among researchers, despite the significant increase in publications over the last decade. Most of the high-impact authors are based at universities in the United States, such as Stanford and Cornell. Regarding international collaboration, the United States leads, followed by Australia, the United Kingdom, Canada, and Spain, all economically developed countries. The keyword analysis indicated that terms such as "environmental education," "sustainability," and "sustainable development" are strongly interconnected and present in the majority of studies. The study concludes that environmental education has become an increasingly relevant field of research, with growing academic interest and potential to influence public policies. However, there is a need for greater collaboration between researchers from different areas and countries to enrich the field and address existing gaps. The bibliometric methodology used in the study provides an overview of the evolution of research in environmental education, identifying the main trends and challenges for the future.
