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

O_LITourism 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. C_LIO_LIUsing 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. C_LIO_LITo 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. C_LIO_LIWhile 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. C_LIO_LIThis 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. C_LI

A global map of human pressures on tropical coral reefs

As human activities on the worlds oceans intensify, mapping human pressures is essential to develop appropriate conservation strategies and prioritize investments with limited resources. Here, we map non-climatic pressures on coral reefs using the latest quantitative data layers on fishing, nitrogen and sediment pollution, coastal and industrial development, and tourism. Across 54,596 coral reef pixels worldwide, we identify the top-ranked local pressure and estimate a cumulative pressure index mapped at 0.05-degree ([~]5 km) resolution. Fishing was the most common top-ranked pressure followed by water pollution (nutrients and sediments), although there is substantial variation by regions. We also find that local pressures are similar inside and outside a proposed global portfolio of coral reef climate refugia. We provide the best available information to inform critical conservation strategies and ensure local pressures are effectively managed to increase the likelihood of the persistence of coral reefs to climate change.

Limiting the loss of terrestrial ecosystems to safeguard nature for biodiversity and humanity

Humanity is on a pathway of unsustainable loss of the natural systems upon which we, and all life, rely. To date, global efforts to achieve internationally-agreed goals to reduce carbon emissions, halt biodiversity loss, and retain essential ecosystem services, have been poorly integrated. However, these different goals all rely on preserving natural ecosystems. Here, we show how to unify these goals by empirically deriving spatially-explicit, quantitative area-based targets for the retention of natural terrestrial ecosystems. We found that at least 67 million km2 of Earths natural terrestrial ecosystems (~79% of the area remaining) require retention - via a combination of strict protection but more prominently through sustainably managed land use regimes complemented by restoration actions - to contribute to biodiversity, climate, soil and freshwater objectives under four United Nations Resolutions. This equates to retaining natural ecosystems across ~50% of the total terrestrial (excluding Antarctica) surface of Earth. Our results show where retention efforts could be focussed to contribute to multiple goals simultaneously. The retention targets concept that we present explicitly recognises that such management can and should co-occur alongside and be driven by the people who live in and rely on places where natural and semi-natural ecosystems remain on Earth.
