**1. Introduction**

Science aims to answer questions, and from a pragmatic approach, science can be understood as a resolution of problems in our society. Science cannot be considered an independent activity, and therefore, it must be remembered that prior studies have been carried out in any given scientific field. Combining scientific aspects with documental aspects gives rise to a certain type of scientific work: scientometric, bibliometric, and informetric studies. These take different titles according to the final approach of the work, such as the following: examining the scholarly literature, evolution, and new trends; worldwide research trends; mapping of the knowledge base; visualizing the knowledge structure; analysis of global research; publication trends; knowledge domain visualization. Scientific literature is losing its relevance more and more quickly, but the aging of literature is not uniform for all scientific subjects. This means that being up to date in a scientific field requires bibliometric studies through which new trends are revealed when undertaking scientific studies of interest to the community. Two topics of special interest to society today are environmental research and public health, and within these larger topics are sub-topics related to global health. Global health, in a broad context, refers to improving health worldwide, reducing disparities, and protecting against global threats that do not consider national borders. This Special Issue aims to provide a global view of all of these global health issues, and through bibliometric studies, we believe that this objective can be achieved. Therefore, articles reviewing the state of the art in any of these fields, bibliometric or scientometric studies, and research articles dealing with a global perspective are welcome.
