Living Planet Index
The Living Planet Index (LPI for short) is an indicator of global biological diversity . It is based on trends in the global population of vertebrate species.
description
The WWF is working with the Institute of Zoology (IOC), the research division of the Zoological Society of London (ZSL) to the project started in 1997 to develop further. The idea of the LPI comes from the WWF and the UNEP-WCMC (UNEP World Conservation Monitoring Center, UNEP World Monitoring Center for Nature Conservation) in order to implement biodiversity as a measurable parameter in the United Nations Environment Program UNEP. The aim of the network is to expand the database to include invertebrates and plants. The data collection in the area, especially in the countries of the south , is to be improved.
The Living Planet Index is calculated on the basis of the development of 14,152 populations of 3706 vertebrate species. The data comes from specialist journals, online databases and government reports, among other things. The species are differentiated according to habitat (dry land, fresh water, sea) and according to biogeographical region. Land and freshwater inhabitants are assigned to the four classic fauna regions of Palearctic , Nearctic , Afrotropic and Neotropic as well as an Indo-Pacific region , marine inhabitants to the six biogeographical regions Arctic , Temperate North Atlantic , Temperate North Pacific , Tropical and subtropical Atlantic , tropical and subtropical Indo-Pacific and seas of the southern temperate latitudes and Antarctica . Since 2014, the global LPI in the form of will -weighted Living Planet Index ( weighted Living Planet Index , LPI-D) indicated, in addition to its calculation, the number of species in the different bio-geographical regions and in the five traditionally distinguished vertebrate large groups ( " fish " Amphibians , " reptiles ", birds and mammals ) is taken into account. The results have been published since 1998 in the Living Planet Report, which is usually published every two years by the WWF .
The oldest data used to calculate the LPI date from 1970. By convention, the LPI has a value of 1 for this year. Since then it has fallen continuously. The last Living Planet Report was published in 2016 and found a decline in biodiversity by 58 percent between 1970 and 2012, which corresponds to an LPI for 2012 of 0.42.
