摘要: Abstract The maintenance of biodiversity and the capacity natural systems to provide goods services for people is affected on different levels by intensity human activities ecosystems. In this study, we apply a Legacy-adjusted Human Footprint Index (LHFI) evaluate spatiotemporal variation anthropic impact in Colombia 1970, 1990, 2000 2015. We identified hotspots change LHFI evaluated pressures regions found that increased between 1970 Andean Caribbean presented highest impact, remaining stable over time. Hotspots were mainly located following regions: (Antioquia, Cauca Valle del states), Amazon (Amazonas, parts Meta, Guaviare Putumayo states) Orinoco (Casanare Meta Vichada states). addition, ecosystems under IUCN ecosystem risk categories are Critically Endangered (CR) Vulnerable (VU) most high level impact. Spatiotemporal evaluation footprint provides new insights about trends constitutes an analytical tool with potential harmonizing land use planning conservation.
