The largest losses, mostly in forests, occurred in the Sundaland, Indo-Burma and Mesoamerica hotspots, all in developing countries

Top biodiversity hotspots of the world lost 148 million hectares (mha) of land to agriculture and urbanisation between 1992 and 2015, a global analysis released October 30, 2020, by the Norwegian University of Science and Technology, said.

Most of the land lost — nearly 40 per cent, or 54 mha — was in the form of forests. The three largest losses in forest area occurred in the biodiversity hotspots of Sundaland (Indonesia), Indo-Burma (mainland southeast Asia) and Mesoamerica.

The three hotspots accounted for forest losses of 11 mha, 6 mha, and 5 mha respectively. This corresponds to a relative loss of 13 per cent, six per cent and seven per cent, respectively, of the forest area originally present in 1992, the study showed.

A ‘biodiversity hotspot’ was defined as an area that contained “exceptional concentrations of endemic species that were undergoing exceptional loss of habitat”, according to the team that conducted the study.

These areas compose 2.3 per cent of the Earth’s surface but have more than half of the world’s endemic plant species, according to the International Union for Conservation of Nature. Thirty-four biodiversity hotspots were covered under the study.
