The project is managed by a committee comprised of key stakeholders from state and municipal entities, universities, and local communities, to promote and generate sustainable local de-velopment strategies. Paraguay has significant geodiversity, particularly in the east-ern region, with rocks ranging from the Paleoproterozoic to Quaternary sediments. Appreciation of this extensive geodiversity only began a decade ago with a focus on heritage value and preservation of certain geological sites. The methodology present-ed here involves a qualitative inventory of geosites and geodiversity sites (GS) with scientific, educational, and tourist value. Additionally, it considers their fragility and vulnerability within the territory of the Geoparque ÑandeYvytykuera, covering the departments of Central, Cordillera, and Paraguarí. The GS with the highest scien-tific value is the columnar sandstones of Cerro Koi. Those with superior educational qualities include the GS Ñemby Hill, Perõ Hill, and Yaguarón Hill. Tourism value is highest at the GS San Bernardino Beach. As for fragility and vulnerability, the Itauguá Fossiliferous Shales GS stands out due to the deterioration and loss of its geodiversity, attributed to a diverse array of unique marine fossils. In conclusion, we recommend adding more locations as a geoconservation strategy, and expanding studies that incorporate quantitative methodologies to provide more precise data and further these and other investigation.
