The year we became unsustainable: Analysis of Spanish production in Sustainability (2020)

The journal Sustainability, published by MDPI, was the journal that published the most papers by researchers from Spanish institutions in 2020. This justifies a detailed examination of the Spanish scientific production in this journal. At the same time, the work of editing monographic issues in which papers with Spanish authors have been published is analyzed. For this purpose, we have identified whether each paper belongs to regular or to special issues of the journal, identifying whether the author of the paper is also editor of the monograph, or a university colleague. The nationality of the editors was also studied. The subject matter of the articles and their belonging to the area of the journal were analyzed. Most of the papers published by Spanish authors were published in special issues (81.6%), mainly edited by authors of the same nationality (63.1%). It is also found that there is an important production carried out by the same editor of the monograph, or by colleagues from the same institution. It is also found that a substantial number of works published in Sustainability (42.3%) have minimal or no relationship with the subject of sustainability. Finally, the implications of these findings are discussed under the light of the publication strategies of Spanish researchers and the science evaluation policies applied in Spain. The main controversial aspects identified have to do with the publication of papers on other subjects, the value of publishing in monographs, which in some cases could be considered as inbreeding, and the short editing times.
