“…Non-renewable georesources include: minerals, rocks, fossils, petrogenetic features, mines, landforms, glaciers, ice age phenomena, and some geomorphological features [14][15][16]. Their main applications include building construction [17,18]; development of smartphones and computers [19,20]; illumination [21]; farming [22,23]; jewelry (gemstones) [24,25], drinking water supply, and development of renewable energies [26].…”

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.
