Cities in Hotspots

Cities in hotspots expanding into remnant habitat

This map locates cities of 300,000 or more people projected to sprawl into remnant habitat in the world's biological hotspots. To make the map urban growth projections are overlaid on top of remnant vegetation data from the Global Land Cover Facility 1 and IUCN Red List 2 of ranges for 3,245 mammal species that are either critically endangered or endangered. Due to technical and time constraints, the research only used mammal species as a start to examine the potential conflicts that lie between immanent urban development and biodiversity. This map draws attention to places in need of urban design strategies to mitigate immanent conflict between urban development (formal and informal) and biodiversity. These cities can each be seen in greater detail in the Hotspots section.
