Toward Sustainable Biocultural Tourism: An Integrated Spatial Analysis of Cultural and Biodiversity Richness in Colombia

1. Tourism plays a vital role in both economic development and depending on the scale, it can also aid environmental conservation. Tourism planning often considers culture-based and nature-based tourism separately, failing to recognize the synergies between them, with the potential to market locations as biocultural destinations. 2. Using Colombia as a case study, we created metrics of taxonomic biological diversity as measured by vertebrate species richness (including birds, mammals, freshwater fishes, reptiles, and amphibians) and institutionalized cultural richness (by counting the number of UNESCO world heritage sites, intangible cultural heritage sites, museums, endemic music festivals, Afro-Colombian territories, and Indigenous reserves), and evaluated the spatial correlations between them. 3. To determine biocultural tourism potential, we evaluated whether biocultural richness was accessible, and mapped potential biocultural tourism supply. By mapping areas of sports fisheries, birdwatching destinations, and airport arrivals we also estimated spatial demand. We also analyzed the difference between demand and supply to assess the realized and untapped potential for biocultural destinations. 4. While biocultural richness is high in the Amazon, Pacific, and Caribbean regions, we found that there are no win-win-win locations where culture, species richness, and accessibility are all high. Areas with great potential for biocultural tourism development largely coincide with designated Indigenous reserves and Afro-Colombian territories. 5. This study underscores the power of integrating cultural and biological variables to reshape the tourism sector. Our paper offers practical recommendations for policymakers, conservation organizations, and local communities seeking to create transformative and inclusive tourism experiences. ### Competing Interest Statement The authors have declared no competing interest.
