The technical and scientific analysis regarding studies of the water surface or groundwater has increasingly taken on a great social impact, which has led to the creation of the term socio-hydrology. Since decision making has a greater weight, considering the social perspective, its study has become more important in the past 20 years. This article aims to carry out a bibliometric analysis related to socio-hydrology using the Scopus database and the application of VOSviewer software for the evaluation of the intellectual structure of socio-hydrology, its conceptual evolution, and its tendencies. The methodology considers (i) search criteria of the research field, (ii) search and document selection, (iii) software and data extraction, and (iv) analysis of results and trends. The results show us the term socio-hydrology as a new scientific discipline that has traces in the Scopus database in the past two decades. However, its application stems from recognising ancestral knowledge alongside other forms of knowledge. Socio-hydrology practice requires participatory models, where the community has a great influence, and for the most part, it guarantees results for the common good. The trend of this topic is growing and open to the criteria of sustainability.

Ecuador has shown a growth in its scientific production since 2011, representing 85% of the total historical production. These investigations are reflected in scientific publications, which address world interest topics and serve as a link for the university, business, and society. This work aims to analyze the scientific production generated by Ecuador in the period of 1920–2020 using bibliometric methods to evaluate its intellectual structure and performance. The methodology applied in this study includes: (i) terms definition and search criteria; (ii) database selection, initial search, and document compilation; (iii) data extraction and software selection; and finally, (iv) analysis of results. The results show that scientific production has been consolidated in 30,205 documents, developed in 27 subject areas, in 13 languages under the contribution of 84 countries. This intellectual structure is in harmony with the global context when presenting research topics related to “Biology and regional climate change”, “Higher education and its various approaches”, “Technology and Computer Science”, “Medicine”, “Energy, food and water”, and ”Development and applications on the Web”. Topics framed in the Sustainable Development Goals (SDGs), sustainability, climate change, and others. This study contributes to the academic community, considering current re-search issues and global concerns, the collaboration between universities and countries that allow establishing future collaboration links.

Worldwide, forest fires exert effects on natural ecosystems, contributing to economic/human losses, health effects, and climate change. Spectral indices are an essential tool for monitoring and analyzing forest fires. These indices make it possible to evaluate the affected areas and help mitigate possible future events and reduce damage. The case study addressed in this work corresponds to the Cerro of the Guadual community of La Carolina parish (Ibarra, Ecuador). This work aims to evaluate the degree of severity and the recovery of post-fire vegetation, employing the multitemporal analysis of spectral indices and correlating these with the climatological aspects of the region. The methodological process was based on (i) background information collection, (ii) remote sensing data, (iii) spectral index analysis, (iv) multivariate analysis, and (v) a forest fire action plan proposal. Landsat-8 OLI satellite images were used for multitemporal analysis (2014–2020). Using the dNDVI index, the fire’s severity was classified as unburned and very low severity in regard to the areas that did not regenerate post-fire, which represented 10,484.64 ha. In contrast, the areas classified as high and very high severity represented 5859.06 ha and 2966.98 ha, respectively. In addition, the dNBR was used to map the burned areas. The high enhanced regrowth zones represented an area of 8017.67 ha, whereas the moderate/high-severity to high-severity zones represented 3083.72 ha and 1233.49 ha, respectively. The areas with a high severity level corresponded to native forests, which are challenging to recover after fires. These fire severity models were validated with 31 in situ data from fire-starting points and they presented an accuracy of 99.1% in the high severity category. In addition, through the application of principal component analysis (PCA) with data from four meteorological stations in the region, a bimodal behavior was identified corresponding to the climatology of the area (dry season and rainy season), which is related to the presence of fires (in the dry season). It is essential to note that after the 2014 fire, locally, rainfall decreased and temperatures increased. Finally, the proposed action plan for forest fires made it possible to define a safe and effective evacuation route to reduce the number of victims during future events.

The excessive use of energy from fossil fuels, which corresponds to population, industrialisation, and unsustainable economic growth, is the cause of carbon dioxide production and climate change. The Water–Energy–Food (WEF) nexus is an applicable conceptual framework that helps manage the balance between human development and natural resource constraints, and it becomes a valuable tool to address the challenges of resource depletion and clean energy. This article aims to analyse the relationship between the WEF nexus and clean energy through a statistical analysis and a systematic review of knowledge on energy sustainability. The methodology involves the selection of bibliographic information databases such as Scopus and Web of Science (WoS), a statistical analysis, specifically the Scientometrics applied to the information obtained, and the identification of 179 scientific publications related to the study variables through a screening process called Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The interaction of green energy and sustainability with the WEF nexus has been approached mainly by developed countries such as China (10%), the United States (9.49%), India (7.26%), and Brazil (5.02%). The review of 55 scientific papers identified strategies that balance economic growth and environmental impact, applying clean energy systems (e.g., solar and wind), and the importance of adaptation to the subsystems of the WEF nexus. This study also highlights adaptability to climate change in rural and urban communities. Therefore, it is consistent with the four pillars of sustainable development (Economic: 7 papers, Environmental: 22, Social: 18, and Cultural: 8). This study highlights the following: (a) the importance of the use of renewable energy either in mixed systems and consumption, energy storage, and seeking energy efficiency in systems adapted to diverse environments and (b) the relevance of community participation in the decision-making process for the use of clean energy, such as a strategy for climate change adaptation.

Water Sowing and Harvesting (WS&H) is an ancestral knowledge widely used as a sustainable technique in water management. This study aims to analyse the importance, promotion, and cultural heritage of WS&H techniques through a literature review in Ecuador, considering applications of ancestral techniques by region (coastal, Andean and insular) with a strengths, opportunities, weaknesses, and threats (SWOTs) analysis and a focus group for a strategy proposal of the water supply. The methodology of this study includes the following: (i) an analysis of the evolution of WS&H studies in Ecuador; (ii) a presentation of WS&H techniques and their applications; and (iii) the contribution of WS&H to the Sustainable Development Goals (SDGs), complemented by a SWOTs analysis. The results show that, in Ecuador, WS&H is a method of Nature-based Solutions (NbSs) applied to the problems of water scarcity and is affordable, ecological, and has high efficiency, improving agricultural productivity and guaranteeing water supply for human consumption. The Manglaralto coastal aquifer, a case study in the coastal region of Ecuador, involves WS&H management and artificial aquifer recharge. WS&H structures became a reference for the sustainable development of rural communities that can be replicated nationally and internationally as a resilient alternative to water scarcity and a global climate emergency, contributing to the SDGs of UNESCO.

Georesources comprise spaces of relevant geological value with the potential to be used and managed as a resource. Therefore, georesources are an essential development factor in the world, mainly oriented to their rational use to improve the quality of life of the surrounding population. This work aims to analyze the main applications, conservation strategies and sustainable use of georesources in the rural area of Manglaralto (Ecuador) through their inventory, assessment and analysis for the adaptation of alternative uses to particular circumstances (e.g., the COVID-19 pandemic). The method used consists of four phases: (i) inventory and mapping of georesources; (ii) description and assessment of georesources using international methodologies (e.g., GtRAM for georoute assessment, hydrogeological characterization using GeoModeller for groundwater assessment, GIS tools for assessing materials with industrial–artisanal interest, and KFM matrix method for the assessment of the level of construction difficulty of sanitary landfills); (iii) georesources complementary applications and (iv) SWOT analysis (Strengths, Weaknesses, Opportunities, Threats) and TOWS matrix preparation (Threats, Opportunities, Weaknesses, Strengths), seeking strategies to guarantee the viability of the use of georesources. As a main result of the investigation, the geolocation of the georesources of the area was obtained. In addition, the assessment of the main georesources such as (i) potential geosites and sites of geological interest (e.g., beaches, cliffs, waterfalls, capes), (ii) groundwater (aquifers), and (iii) materials with artisanal and industrial interest (e.g., clays, sands). Finally, the study allowed us to define areas to develop landfill infrastructure, identify ecosystem services, and construct tsunami refuge site proposals. The case study addressed shows that the inventory and definition of the use of geological resources constitute a fundamental process for the economic, social, and environmental development of the population.
