Geoparks are unique geographical areas whose geological significance is worthy of UNESCO designation as a Global Geopark. As of 2022, 177 geoparks located in 46 countries have this designation. The aim of this paper is to identify and analyse the worldwide scientific production published in the Web of Sciences database in the context of Geoparks. The methodology used was bibliometric analysis, which allows for the rigorous exploration and analysis of large volumes of data. To this end, descriptive and relational indicators were obtained for the field of study; performance analysis, scientific mapping, and network analysis. A total of 324 articles were identified, the first of which was from 1999 by Wolfgang Eder, in which he presented the UNESCO initiative on the creation of geoparks as a tool to promote a better understanding of the geological heritage and the rational use of the Earth’s crust; the rest of the articles were written after the programme was launched (2001). Few authors work on the subject continuously, the author with the highest number of publications has six, and most of the authors with a single authorship are transient. The countries with the highest number of publications are China, followed by Spain, Portugal, Brazil and Italy, where scientific production is concentrated; the high rate of transience indicates that many countries have only one publication. Most publications are concentrated in two journals: geoheritage and geosciences. In the early years (1999–2003), publications were associated with two research areas, geology and palaeontology, and it is in the last five years (2019–2002) that the areas of knowledge showing interest in the subject have diversified.

It is a fact that society has increased the need for mobility throughout the world. In that regard, it has become aware of the problems associated with the use of fossil fuels such as jet-fuel. As alter-natives, the use of bio-jet fuel has been proposed, which is a biofuel that researchers have evaluated and developed as an environmentally friendly alternative. The development of research on the topic of biofuels has generated a growing number of alternatives in the methods, technologies and raw materials for the production of bio-jet fuel. In this work, a bibliometric study has been developed to analyze the evolution of publications, the contribution of authors, countries, in terms of citation productivity on the topic of bio-jet fuel. Scientific publications were searched in the Scopus database for the period 2001 to 2021. The results showed that the publications have grown exponentially in the last 10 years. The most influential institution and country are from China. “Renewable and Sustainable Energy Reviews” is the most cited journal in the field of bio-jet fuel. The growth rate of publications was estimated using the Gompertz model, the rate was 0.2232 y-1. Most of the documents were published in journals Q1.

The ongoing depletion of fossil resources, the energetic autonomy of countries, soaring prices for petroleum and climate change have stimulated research and development on renewable energy as biofuels. In this work, a bibliometric analysis of the Web of Science database was carried out to identify the research related to sugar beet to biofuels. The equation logistic was used to quantitatively describe the growth of the publication of sugar beet in the biofuels field. The results show that the publications of sugar beet for biofuel have a rate of growth of 0-1898 year −1 . Germany and the USA were the countries with high influence for research in the field of sugar beet for biofuels. The journal Zuckerindustrie was the referent to publications in the field of study. From 2003 to 2019, the exponential growth of publications was found, this profile of growth can be attributed to the development of renewable energy and the relevance of global warming, security energetic and laws that promoted clean energy. This work shows that the logistic equation can be used to predict the evolution of publications in the field of study.

The aim of this article is to provide a comparative analysis regarding the production of the scientific research of biorefineries in India using Web of Science and Scopus databases. The rate of growth of publications, production, citation, correlation and overlap between databases, authors, journals and universities has been analyzed. The results of both databases show exponential growth of publications in India from 2015-2020 on the topic of biorefineries. The index of citations per document is similar in WoS and Scopus. The correlation of citations was found to be high between databases used. Most Indian authors publish in quartile 1 (Q1) journals. Most of the published documents are review and the highest number of citations were found in the journal "Renewable and Sustainable Energy Reviews". Both databases present a series of publications on the topic of biorefinery by authors from India, the difference between the databases lies in the indexing criteria and the updating of the journals.
