Biodiversity is an essential component of nature, relegating the aspects of geodiversity, which provides geological and landscape variety to a territory. However, the importance of geodiversity and its social, economic, educational, scientific, and technological impact on a region, are not well understood. This article measures the geoheritage values of Guayaquil, a port city in Ecuador, via surveys and analyses of variables, with the aim of proposing guidelines or strategies that promote the knowledge and diffusion of that geoheritage. Our methodology included (i) a review of historical landmarks of Guayaquil and their relationship with geodiversity, (ii) a survey and data tabulation, (iii) an analysis of the local population’s perception of the city’s geoheritage, and (iv) the development of geodiversity strategies using computer tools. Our results determined that people approach areas of interest because of each site’s biodiversity and the available information about the site. Once there, they can obtain knowledge about the city’s geology, geodiversity, and urban geotourism. Therefore, geoheritage is an essential consideration in establishing educational plans, initiatives, and promotion strategies. Furthermore, the identification of a city’s heritage values following geoeducation, and the recognition by society of the city’s geosites and their historical–scientific significance, will provide a basis for using geotourism in a context of sustainability.

Geological heritage represents and brings together geological elements of great local and global relevance. It also promotes conservation and sustainable use. This study aims to perform a bibliometric analysis of the contributions that address the topics of geological heritage and geosites, using the Scopus and Web of Science databases for the knowledge of trends and research focuses in this area. The methodology consists of: (i) the preparation of the idea and gathering information from a search on the subjects of interest (geoheritage and geosites); (ii) the merging of the databases and applying automated conversions; and (iii) the analysis of the results and the literature review. The first phase of the work identified 2409 and 1635 documents indexed in Scopus and WoS, respectively. The merged global database (2565 documents) identified the following words as analysis topics: geoconservation, geotourism, geopark, and geodiversity. The analysis also revealed the top five countries in scientific contributions as Italy (12.1%), Spain (8.77%), China (5.67%), Portugal (5.35%), and Brazil (5.31%). Finally, most of the publications focus on the characterisation, assessment, and development of geosite initiatives. The main lines of action and contributions to the topics (7.91%) highlight the fact that geoscientists worldwide value geosites for geoconservation and geotourism strategies.

Geodiversity has elements of exceptional scientific value that are considered to represent geoheritage, or geological heritage. One way to conserve and promote the knowledge of these elements is through the initiatives of United Nations Educational, Scientific, and Cultural Organization (UNESCO) Global Geoparks, which, over a decade ago, began to notably highlight a new sustainable tourism alternative called geotourism, or geological tourism, that promotes the protection of the unique geological resources of territory and, at the same time, provides social, economic, and environmental benefits. This study aims to investigate the scientific information related to geotourism in the Scopus database through a bibliometric analysis, using the VOSviewer software, for the evaluation of the structure, conceptual evolution, and trends of geotourism following related publications. The research comprises four study phases: (i) search criteria of the research field; (ii) search and selection of documents; (iii) software and data extraction; and (iv) analysis of results and trends. The results present geotourism as a scientific discipline that is in a phase of exponential research growth and exhibits its scientific productivity from 1984 to 2019, where three main periods are differentiated: introduction, theoretical development, and diversification of information. The most active research area is geomorphological heritage, which is very far from the emerging line of research of engineering geology in geotourism. However, growing exploration during the last six years has generated the development of various geoscientific branches promoted by geotourism that, currently, present their research area trends such as geosites, geoheritages, and geoparks.

This study offers a detailed assessment of the geosites and mining sites present in the Zaruma-Portovelo mining district (Ecuador) through their qualitative and quantitative assessment. It shows up the potentiality of this area taking advantage of its geological-mining heritage. The methodological process includes: (i) compilation and inventory of all the sites within the study area with particular geological or mining interest; (ii) preparation of reports and thematic cartography, (iii) assessment and classification of the elements of geological-mining interest; (iv) SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis and TOWS (Threats, Opportunities, Weaknesses, Strengths) matrix preparation seeking strategies to guarantee the viability of geotourism. A total of 16 sites of geological interest and 11 of mining interest were identified. The 77% of these sites was proved to be of high and very high interest in scientific terms. Likewise, their susceptibility to degradation assessed from their vulnerability and fragility was found to be high or very high in the 30% of the cases. As for the protection priority, all the studied sites obtained a medium-high result. Finally, the study based on the SWOT-TOWS revealed the possibility of applying action strategies in order to facilitate the compatibility of geotourism with the current productive activities, despite the difficult situation in the study area created by mining activities.
