This paper reviews the academic literature related to religious tourism through a bibliometric study and citations of articles indexed in the multidisciplinary database Web of Science (WoS). Through an advanced search by terms, a representative set of 103 documents that form the ad-hoc basis of the analysis were selected. In view of the results, it is concluded that the United States is at the forefront of research, with almost 20% of the articles affiliated to one of its centres, mainly university centres. Publications on religious tourism are currently in an exponential growth stage, supported by the annual increase in the number of citations received. These papers are published in a small number of journals well positioned in their JCR category, classified within the field of Social Sciences Research.

Island ecosystems have very specific physical, economic and socio-cultural characteristics, which are shared by most of these ecosystems regardless of their geographical area. These characteristics include well defined geographical boundaries that lead to a greater degree of isolation, lack of economically exploitable resources, great external dependence for consumption, cultural and natural heritage with a high uniqueness level and a high concentration of endemic plant and animal species. All of them are responsible for the high development dependence level linked to the tourism activity of these ecosystems. Thus, island ecosystems are currently an important international tourism destination, where a great diversity of very attractive natural and cultural resources and of great heritage value are concentrated. This fact allows for the development of tourism activities of great heterogeneity among countries or regions of the world that host these island ecosystems. The aim of this research was to identify and analyze, through a bibliometric and bibliographic analysis, the scientific production indexed in the international Scopus database, which addresses the subject of use of cultural and natural resources by tourism in island ecosystems. This scientific mapping allows us to observe the evolution of scientific production in this field of study. The results show that this is a new subject (a large number of transient authors), predominantly affiliated with the United States and Spain. The most followed research lines to date are destination management followed very far by responsible environmental behavior and the impacts of sustainable development. However, the keywords with the highest co-occurrence show that the hot topics are tourism exploitation in the ecotourism field and sustainable tourism development. This research is considered the first bibliometric study carried out which is related to this thematic approach, providing a clear in-depth analysis for researchers and thereby facilitating the approach of future research work.

Purpose: The purpose of this paper is to present an in-depth analysis of the current state of research related to Education for Entrepreneurship in Higher Education. Education for entrepreneurship is one of the fastest growing fields within academic training worldwide, which is a good indicator of the importance that entrepreneurship and the creation of companies have for the economic development of any society. Education for entrepreneurship is essential, not only to promote an entrepreneurial spirit among young people but also to provide the basic skills, knowledge and innovative attitudes to carry out new business models successfully.Design/methodology/approach: A descriptive bibliometric study was carried out with analysis of citations of 164 articles included in the multidisciplinary database Scopus (Elsevier) until 2017.Findings: The results obtained show a growing interest of the scientific community in its study, as shown by the significant increase both in the number of articles and their citations in recent years.Research limitations/implications: In any bibliometric study, the limitation involved when analysing the results, the choice of a specific database and a specific search equation must be taken into account. With respect to the search terms, those used in this research may not be possible, the inclusion of new terms will alter the results. On the other hand, the aim was not to evaluate the quality of the content of the selected articles at any time, an objective that can be considered in a subsequent investigation, but a descriptive-quantitative analysis of the works and citations related to Education for Entrepreneurship in Higher Education, present in Scopus. To expand the present study, it would be interesting to examine the documents indexed in other databases (Redalyc, Scielo, ProQuest, Directory of Open Access Journals[DOAJ]), together with the possibility of including comparative and overlapping studies between them.Originality/value: The purpose of this work is to serve as a reference for researchers who are developing their studies in the general field of education for entrepreneurship and more specifically in the field of higher education, to improve their knowledge on the most relevant articles, the most productive authors or the key scientific journals that address this topic.

While global water demand continues increasing, the quantity and quality of water resources is decreasing in many regions. Conflicts over competition in the use of water are likely to increase as societies face social, economic and political challenges, especially aggravated by climate change. In this scenario, sustainable management of water resources is a key priority to meet the growing demand for water and to achieve a safe and environmentally sustainable future supply. The main objective of this article was to show an image of the international scientific production related to “Sustainable Water Resources Management” by using the comparative bibliometric study of the documents indexed in the WoS(Web of Science) and Scopus databases as a tool; and to analyze relevant aspects such as their coverage, correlation, overlap, growth, citation, dispersion or concentration, among others. For this purpose, and by means of an advanced search of terms, a representative set of 160 articles in WoS and 210 in Scopus were selected (with a time limit that limited the results to anything published before 2017, including 2017), which form the ad-hoc basis of the analysis. Their significant increase in both the number of articles and citations received in the last 10 years demonstrates the growing interest of the scientific community in its study. Regarding the analysis of the databases, although WoS and Scopus differ in terms of scope, volume of data and coverage policies, both information systems are complementary and non-exclusive. Despite their similarities, Scopus performs better coverage in the specific area of Sustainable Water Resource Management by collecting a greater number of articles and receiving a greater number of citations.

Debates on how growth and urbanization affect the environment have been intense, but they lack the global perspective. Therefore, this research examined those relationships, and to a greater extent other forms of global environmental degradation, such as foreign direct investment (FDI). It also explored the relationships between industrialization and technologies. The results, using Westerlund cointegration and quantile regressions over the period 1995–2017, show cointegration and regional heterogeneities in the environmental transmissions of economic development, industrialization, renewable energy, urbanization and FDI. The results show that economic development generates more environmental degradation in all quantiles at a global level, whereas urbanization and renewable energy reduce environmental degradation in all quantiles, with the highest effect being in the upper quantiles. On the other hand, industrialization affects the lower quantiles negatively and significantly but affects the upper quantiles positively. Finally, the empirical analysis supports the paradise haven or pollution halo hypothesis (PHH) for the 40th, 50th, 60th and 80th quantiles. This suggests that FDI inflows have a detrimental effect on the host country for these quantiles. Therefore, among the objectives of the policies are to give priority to more sustainable economic growth processes, which contribute to reducing environmental degradation, and furthermore to reinforce strict environmental laws on investment inflows and to build sustainable urbanization and industrialization processes for countries.

In the last decades in developing countries, the tourism sector has been immersed in an intense process of strengthening the participation of local communities through the so-called community tourism initiatives, whose main objective is to improve the quality of life of the inhabitants of host communities, ensuring the subsistence of traditional culture. Its growing momentum as a means for sustainable tourism and a strategy for social development has generated a large amount of academic literature, and it is necessary to analyze its presence in the main multidisciplinary databases. Thus, the main purpose of our article is to show the current state of scientific production on community tourism through a bibliometric comparative study of the documents indexed in the WoS and Scopus databases, dealing with aspects such as their coverage, correlation between both bases, overlapping of documents and journals, growth, dispersion or concentration of articles, among others. For this purpose, and by means of an advanced search by terms, a representative set of 115 articles in WoS and 185 in Scopus were selected, with the time limit set in 2017. These form the ad-hoc basis of the analysis. In view of the results, it is concluded that, although WoS and Scopus databases differ in terms of scope, volume of data, and coverage policies, both information systems are complementary but not exclusive. Although the documents and the results of their analysis are in many aspects similar, Scopus has a better coverage in the specific area of community tourism due to collecting a greater number of articles, journals and signatures, and its articles receiving a greater number of citations.
