Sensitivity Analysis of APLIS Method to Compute Spatial Variability of Karst Aquifers Recharge at the National Park of Viñales (Cuba)

In this contribution, sensitivity analysis of APLIS method is realized. APLIS method is based on a GIS analysis where the principal variables which influenced the recharge are taken into consideration, with a special emphasis on carbonate aquifers. The methodology is applied to carbonated aquifers of the tropical mountains at the National Park of Vinales. As the method has been developed from Mediterranean conditions, some modifications were required to improve the soil. The method shows acceptable results taking into account antecedent studies in the area. Results of sensitivity analysis of map removing show that the relative influence in the final recharge map is L>I>S>P>A. The single parameter sensitivity analysis shows some deviations between the empirical and the real weighting.

Advances in Geoconservation in Cuba: Assessment of the Guaniguanico Range and Guanahacabibes Plain (Pinar del Río)

The application of geoconservation concepts in Cuba is very recent, despite the wide body of knowledge accumulated through the study of Cuban geology. Recently, the establishment and consolidation of a National System of Protected Areas that stresses interaction with scientific institutions has greatly helped initiate geoconservation in Cuba. In this study, we review the geoconservation criteria used in the management of protected areas, their precedents and administrative framework. We used the methodology proposed by Bruschi (2007) for the characterisation, assessment and management of geodiversity resources, and modified its criteria for use in selecting geosites. We have applied the methodology to assess the Guaniguanico Range and the Guanahacabibes Plain where 162 geosites were defined. Of the 162 geosites assessed, 107 were at Viñales National Park, so it could be a potential area to become the first Caribbean Geopark.
