Living Planet Index

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 partnership 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 data for the index in the first few years of the project.
Results are presented biennially in the WWF Living Planet Report, on the World Wide Web, and in publications such as the Millennium Ecosystem Assessment and the UN Global Biodiversity Outlook. National and regional reports are now being produced to focus on relevant issues at a smaller scale. The latest edition of the Living Planet Report was released in September 2014 (LPR 2014- Species and spaces, people and places). The previous version of the report, published in 2012, was launched from space by astronaut André Kuipers in the International Space Station, in collaboration with the European Space Agency.
Between 1970 and 2010 the index fell by 52%. This global trend suggests that natural ecosystems are degrading at a rate unprecedented in human history.
The current Living Planet Database (LPD), maintained by ZSL, contains almost 16,000 population trends for more than 3,500 species of fish, amphibians, reptiles, birds and mammals.
The global LPI is calculated using over 10,000 of these population time-series which are gathered from a variety of sources such as journals, online databases and government reports.
Each species trend is aggregated to produce an index for the terrestrial, marine and freshwater systems. This process uses a weighted average method which places most weight on the largest (most species-rich) groups within a biogeographic realm. This is done to counteract the uneven spatial and taxonomic distribution of data in the LPD. The three system indices are then averaged to produce the global LPI.
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 work by the Indicators and Assessments Unit 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 aim to have 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 and plants.
