Living Planet Index

Living Planet Index

"The Living Planet Index (LPI)" is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.

The LPI provides the general public, scientists and policy-makers with information on trends in the abundance of the world’s vertebrates and offers insights into which habitats or ecosystems have species that are declining most rapidly. This information can be used to define the impact humans are having on the planet and for guiding actions to address biodiversity loss.

The World Wide Fund for Nature (WWF) is working in collaboration with the Institute of Zoology (IoZ), the research division of the Zoological Society of London (ZSL), to further develop the project which began in 1997.

The Living Planet Index was originally developed by WWF in collaboration with UNEP-WCMC, the biodiversity assessment and policy implementation arm of the United Nations Environment Programme. UNEP-WCMC collected much of the data for the index in the first few years of the project.

Results are presented biennially in the "WWF Living Planet Report", on the worldwide Web, and in publications such as the Millennium Ecosystem Assessment and the UN Global Environment Outlook.

Separate indices are produced for terrestrial, marine, and freshwater species, and the three trends are then averaged to create an aggregated index.

Between 1970 and 2003, the index fell by about 30%.

This global trend suggests that we are degrading natural ecosystems at a rate unprecedented in human history.

The current "Living Planet Database (LPD)" maintained by ZSL, contains over 6,000 population trends for more than 1,400 species of fish, amphibians, reptiles, birds and mammals.

Convention on Biological Diversity

In April 2002, at the Convention on Biological Diversity (CBD), 188 Nations committed themselves to actions to: "“… achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional and national levels…”" The Living Planet Index is one of the "indicators designated for immediate testing by the CBD" as a means of measuring progress towards the 2010 target, specifically for trends in abundance and distribution of species. The work at ZSL is concerned with ensuring the most rigorous and robust methods are implemented for the measurement of population trends, expanding the coverage of the LPI to more broadly represent biodiversity, and disaggregating the index in meaningful ways (such as assessing the changes in exploited or invasive species).

Building the LPD network

Population data invariably comes from the better monitored regions of the world; however a network of organisations collecting species population data is currently being developed. With the regular addition of high quality data to the LPD the LPI will provide greater coverage of species from poorly known taxonomic groups and regions. In addition, ZSL and WWF have recently begun forming partnerships to develop LPIs for invertebrates [http://en.wikipedia.org/wiki/Invertebrate] and plants.
