This article aims to present research conducted on the literature regarding Multi-objective Optimization (MOO) for routing problems with environmental considerations (EC), referred to here as Multi-objective Optimization for the Green Vehicle Routing Problem (MOOGVRP). A Brazilian database, CAPES (Coordination for the Improvement of Higher Education Personnel), was used to collect articles of general application, case studies and reviews in English starting from, since 2012. The terms “green vehicle routing problem” (GVRP), “pollution routing problem” (PRP), “vehicle routing problem in reverse logistics” (VRPRI.) and ” multi-objective” were used in the research protocol. Consequently, this study obtained 1,744 research results that, following the application of the filtering criterion, resulted in a sample of 76 articles from 38 journals, for which a bibliometric data (bibliometric review) survey was conducted. When dealing with the bibliometric data of the sample, it was possible to identify information such as the number of publications per year and types of published works. Information was also identified regarding the most frequently used journals and the countries and institutions that published the most articles on the proposed theme. It was also possible to analyze the frequency of the protocol terms in the title, abstracts and keywords, the relationship between taxonomies, vehicle fleet types, multi-objective procedures, and VRP procedures. Information was also found regarding solution procedures, number of objectives, and programming languages for computational implementation, the frequency of the most used objectives, and the most cited articles in the sample. The originality of this article lies in how the research is presented, highlighting the results and particular details obtained through the survey, which may be considered of great academic importance in the sense of guiding the trends for future research.

Although humans have interacted with wildfires for millennia, a science-based approach to fire management has evolved in recent decades. This paper reviews the development of fire-management research, focusing on publications that use this term in their title, abstract, or keywords identified on the Scopus platform. This resulted in the identification of 5624 documents published between 1973 and 2021. Publication rates have particularly increased since 2010. The paper details the characteristics of this body of the literature, including the main authors, institutions, and countries. Furthermore, it considers the bibliographic networks, main research foci, and the publications’ study areas. First, these analyses provide researchers interested in fire management an overview of the field and its most prominent sources, authors, and publications. Second, they invite reflection on the current state of fire-management research. In particular, the considerable disparities in spatial foci and countries of authorship suggest that the challenges of today’s problems in fire management are more likely to be overcome with a more balanced global research effort.

The world’s cultural and natural heritage has been gradually affected by climate change, and although the research agendas of many countries have included this reality since 2003, there is still an incipient approach to it, with analysis techniques used being limited. In addition, there are very few case studies that describe in detail the adaptation processes of spaces to these new conditions. The aim of this research is to identify the scientific production related to the impact of climate change on cultural and natural heritage indexed in the international databases Scopus and Web of Science (WoS), which will enable to establish maturity of the research on this subject. The methodology used for the analysis of the data obtained is bibliometric analysis; evaluative and relational measures are applied to a set of 78 articles (45 in Scopus and 33 in WoS) and to a joint base of 47 articles after deleting those articles that overlap in both databases. The result is a scientific mapping that enables observing of the evolution of knowledge generation in this field of study. The main findings show that research is incipient, with a large presence of transient authors with a single publication, the research is limited to the geographical scope of Europe and North America, neglecting many other areas, the impact which is measured by the citation of articles is very low, the relational measures corroborate that the thematic approach is new by identifying a high presence of isolated relationships among authors. The results obtained will be very useful for researchers working in this scientific area, as they can find a synthesis of scientific production in this document, allowing them to draw their own conclusions regarding the current gaps in research; constituting the starting point of their research, with the aim of filling these gaps.

A global review of animal translocation programs. We performed a bibliometric analysis to investigate the efficiency of release techniques (soft and hard-release), to analyse the characteristics and outcomes of the translocation programs, to identify knowledge gaps, and to provide recommendations. Animal conservation studies involving animal release to the wild increased significantly over the 31 years studied and were more frequently performed with terrestrial mammals than with other taxonomic groups. Most of the studies were performed by researchers from developed countries. Translocations occurred mostly in temperate regions, with almost no translocations occurring in the tropics. Almost 60 % of the studies did not provide information regarding the success or failure of the translocation programs. The most commonly used technique was hard release. Wild-caught specimens were preferred for translocations. Translocation programs were less common for groups like amphibians, fishes, and invertebrates. If criteria for suitable translocation are met, this management tool should also be conducted for tropical threatened species, led by native researchers. Furthermore, criteria for successful translocation should be clearly identified in order to improve future conservation actions.
