🗞️ Why in News WWF released the Living Planet Report (LPR) 2026, subtitled The Science of Hope, on 8 October 2026. Its Living Planet Index (LPI), produced by the Zoological Society of London (ZSL), shows a 73% average decline in the size of monitored wildlife populations between 1970 and 2022, with freshwater populations down 85%. The report pairs the warning with a case for positive tipping points in the energy, food and finance systems, ahead of COP17 of the Convention on Biological Diversity (CBD), scheduled to open on 19 October 2026 in Yerevan, Armenia.
New to this topic? Start here: the basics in plain words (revision card 1 of 7)
The headline number is easy to remember and easy to misread. A 73% decline does not mean that 73% of animals, or 73% of species, have gone. It is the average change in the size of 35,803 monitored populations of 5,790 vertebrate species: amphibians, birds, fishes, mammals and reptiles. Getting that distinction right is the most important Prelims point in this report, and the first thing a Mains answer should state.

What the Living Planet Index Measures, and What It Does Not
The LPI “measures the average change in the size of wild populations of vertebrate species over time”. It tracks relative abundance, not head counts. The report gives its own example: a population that falls from 20,000 to 10,000 individuals and another that falls from 200 to 100 have both declined by 50%, even though far fewer animals were lost from the second. Working in percentages is what lets populations of very different sizes be combined into one index.
The report itself (Box 1.2) rules out the first two popular misreadings below, and the third follows from what the index measures:
- It does not mean there are 73% fewer wild animals than in 1970. In the report’s words: “The LPI measures changes in relative abundance, not the total number of animals.”
- It does not mean 73% of species or populations are declining. Around half of the populations studied are stable or increasing; “these gains are outweighed by the greater magnitude of losses elsewhere when calculating a global average.”
- It is not a count of extinctions. Extinction is tracked by a different measure: documented extinctions show species “disappearing at rates 100 times or more above the pre-human background rate”.
How the Living Planet Index reaches 73%
From each population’s own change to one average, and three readings the number does not support.
The LPI is one of four indicators the report reads together. “The four indicators approach biodiversity from different angles, and they point in the same direction.”
| Indicator | What it tracks |
|---|---|
| Living Planet Index | the average change in the size of monitored vertebrate populations |
| Red List Index | how the extinction risk of species is changing |
| Biodiversity Intactness Index | how much of a region’s original biodiversity remains, compared with pre-industrial conditions |
| Documented extinctions | the rate at which species are disappearing: 100 times or more above the pre-human background rate |
A built-in bias, and its correction. Charismatic birds and mammals and commercially harvested fish are better monitored than other groups. Temperate species are also better represented than tropical ones, which have seen steeper declines since 1970. The index offsets this by “giving greater weight to populations from more biodiverse regions and species groups”. The report adds a caution of its own: the LPI “is not designed to be a comprehensive indicator as it represents just one measure of the state of Earth’s biodiversity.”
Where the Decline Is Steepest
By realm
| Realm | Decline, 1970 to 2022 | Range | Average fall per year |
|---|---|---|---|
| Freshwater | -85% | -90% to -77% | 3.6% |
| Terrestrial | -69% | -78% to -57% | 2.3% |
| Marine | -59% | -69% to -45% | 1.7% (the slowest) |
- Freshwater: fish are often threatened by changes to their habitat, “including dams and diversions, which can block essential migration routes.”
- Terrestrial: the main driver is the loss and degradation of natural habitat. An estimated 420 million hectares were deforested between 1990 and 2020, with conversion to permanent agriculture the leading driver.
- Marine: the index is dominated by fish, particularly managed fish stocks, where better incentives, regulation, enforcement and electronic monitoring are helping recoveries after years of overfishing, and this is reflected in the lower overall decline. Sharks and rays, however, “continue to show steep declines”, which is often not apparent in a global average.
By region
The regional indices use the regions of IPBES, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services, and cover terrestrial and freshwater populations only. Marine populations are not part of them.
| IPBES region | Decline, 1970 to 2022 | Range |
|---|---|---|
| Latin America and the Caribbean | -95% (the fastest of any region) | -97% to -91% |
| Africa | -80% | -91% to -57% |
| Asia and the Pacific | -49% | -72% to -8% |
| North America | -28% | -51% to +5% |
| Europe and Central Asia | -23% (the slowest) | -37% to -3% |
- Latin America and the Caribbean: conversion of grasslands, forests and wetlands, damming of rivers, overexploitation and, more than in other regions, climate change and disease.
- Africa: trends are negative on average in all groups, and monitored freshwater fish are the most severely affected.
- Asia and the Pacific: threats range from invasive species on Pacific islands to overexploitation and habitat degradation for freshwater fish, for example in the lower Mekong.
- North America and Europe: the smaller declines partly reflect the 1970 baseline. Large-scale damage to nature had already happened before 1970, so many populations may have stabilised or be rising from a lower base.
The report gives no India-specific LPI figure.
The Same 73% as in 2024 Is Not a Sign of Stability
The 2024 report also headlined 73% (72.9%), but for 1970 to 2020. The 2026 figure (73.2%) runs to 2022. The report is explicit that this “doesn’t imply that average wildlife population sizes have remained stable in the last two years.” Each edition adds new data, sometimes covering earlier periods, so the whole series is re-estimated. Compared with the 2024 dataset, the 2026 index has 967 additional populations and 295 new species, and 669 populations have been updated with new data.
WWF’s own 2024 release put the rule plainly: “successive iterations of the LPI are not directly comparable as they contain different sets of species.”
The same caution applies to the regional and realm figures. The 2024 report had put Asia and the Pacific at -60% and the marine index at -56%; the 2026 report gives -49% and -59%. These are revised estimates on a larger dataset, not a recovery in Asia or a fresh collapse at sea. Do not read them as a two-year trend.
What Drives the Loss
The threats most often reported for monitored populations, in order:
- Habitat loss and degradation
- Overexploitation
- Climate change
- Pollution
- Invasive species
- Disease
Behind these threats the report sees three systems: “the food system is the leading cause of habitat loss, the energy system fuels climate change, while the finance system bankrolls harmful activities.”
Signs of Recovery
The report highlights four recoveries as proof that targeted conservation works. It also warns that the declines “cannot be reversed by conservation efforts alone.”
| Species | What the report records |
|---|---|
| Tiger (Panthera tigris) | wild numbers up by over 70% between 2010 and 2025, from 3,200 to around 5,700 (camera-trap estimates), “the first documented reversal of their longterm decline” |
| Green sea turtle (Chelonia mydas) | in 2025 the first marine turtle ever downlisted from Endangered to Least Concern on the IUCN Red List, after 50 years of work across some 80 nesting countries |
| Atlantic and Pacific bluefin tuna | collapsing after decades of overfishing, they have recovered to the point where neither is now considered threatened |
| Southern African elephants | stable or growing in many of the places where local communities lead the management of the land; the African savannah elephant (Loxodonta africana) still declines across much of its range and remains Endangered overall |
The tiger recovery came from “coordinated action across scales”: national tiger recovery plans, intergovernmental commitments through the Global Tiger Initiative, professional ranger units, protected area expansion, cross-border anti-trafficking work and demand-reduction campaigns. The report does not break the tiger figure down by country. For India’s own tiger reintroduction work, see our page on the tigress reintroduction at Buxa Tiger Reserve.
The Report’s Hook: Positive Tipping Points
Tipping points are usually discussed as risks, such as the collapse of coral reefs or the loss of the Amazon rainforest as a carbon sink. The report argues that the same dynamic can work the other way. In its definition, “A positive tipping point occurs when a system crosses a threshold into a healthier state, and the change begins to reinforce itself through amplifying feedback loops. Once that happens, the change becomes faster, cheaper and harder to reverse.” The tipping-point research in the report is by the University of Exeter.
Three systems, three stages of a positive tipping point
Energy has tipped; food and finance are still in the enabling phase.
The report places the three systems that drive nature loss at different stages:
- Energy: past the tipping point. The global energy system “has passed a positive tipping point and entered its acceleration phase”. Solar is now “the cheapest source of new electricity generation in most countries”, global solar capacity is doubling every three years, and electric vehicles (EVs) were more than 25% of new car sales globally in 2024. Solar and wind together supplied around 14% of global electricity generation in 2024, up from less than 5% in 2015.
- Food: the enabling phase. Positive change is under way, through nature-positive production, sustainable trade and consumption, healthy and sustainable diets, and less food loss and waste, but the system has not tipped.
- Finance: the enabling phase, at an early stage. The sector needs to stop financing harmful activities, value nature and climate as material risks, create regulatory certainty and close an annual US$1.3 trillion biodiversity financing gap.
The deadline is the decade itself: food and finance “need to reach their own tipping points within this decade if the 2030 goals are to remain within reach.”
Where India Appears in the Report
The report names India in a few places that are useful in an answer:
- Energy: “Both China and India appear to be on the cusp of decoupling economic growth from rising fossil fuel consumption, with India shifting toward a solar-powered economy even faster than China.”
- Electric two- and three-wheelers: India is named among the “key centres of innovation”, alongside East Africa, Southeast Asia and China. In 2024, 38% of global two-wheeler sales and 80% of three-wheeler sales were electric.
- Water commons: “in parts of rural India”, restoring traditional rainwater harvesting structures (johads) with community groundwater management “triggered a social tipping point”. As water returned, vegetation recovered, farm productivity rose, women’s workload fell and men returned home.
The report does not discuss India’s flagship species. Government of India figures, which are not from the report, give an answer local evidence:
- Asiatic lion: “The population of Asiatic Lion in the country has increased from 674 in 2020 to 891 in 2025” (Ministry of Environment, Forest and Climate Change, Parliament reply, PIB, 5 February 2026).
- Riverine dolphins: the 2021-23 nationwide survey estimated around 6,327 riverine dolphins in India: Ganges river dolphins across several river systems and a small population of Indus river dolphins in the Beas. The second rangewide estimation under Project Dolphin was rolled out from Bijnor, Uttar Pradesh, on 17 January 2026 (PIB).
The Policy Frame: KMGBF and COP17
- Kunming-Montreal Global Biodiversity Framework (KMGBF): agreed in 2022 “by almost every country through the UN Convention on Biological Diversity (CBD)”. It has 23 targets for 2030, and its four goals for 2050 include “increasing the abundance of native wild species to healthy and resilient levels”, the very quantity the LPI tracks. The report names as a key strength of the framework that, going beyond traditional conservation, it “calls for a whole-of-society approach”.
- Target 3, “30x30”: “Ensure and enable that by 2030 at least 30 per cent of terrestrial, inland water, and of coastal and marine areas ... are effectively conserved and managed”.
- The report’s critique: “30x30 counts hectares, not the biodiversity value of what is protected.” It also notes that “The GBF does not measure what one country’s consumption does to another’s ecosystems.”
- COP17 (scheduled): COP17 of the CBD is due to begin on 19 October in Yerevan, Armenia. WWF says meeting the 2030 targets “will require faster implementation, greater investment, stronger political leadership and deeper action across the whole economy and society”, and that the transition must be “fair and inclusive”.
For the CBD and the framework in more detail, see our page on International Biodiversity Day 2026 and the KMGBF.
Reading the Report Critically
What makes it credible. It is a long series (52 years) built on a large and growing dataset, and its direction matches three other indicators: the Red List Index, the Biodiversity Intactness Index and documented extinction rates.
What limits it.
- An average of percentage changes treats a fall from 200 to 100 like a fall from 20,000 to 10,000, so it says nothing about how many animals were lost.
- Monitoring favours charismatic birds and mammals, harvested fish and temperate regions; the index offsets this by seeking more data and by weighting.
- Each edition re-estimates the past, so headline numbers cannot be directly compared across editions.
The way forward, as the report frames it.
- Treat conservation successes (tigers, turtles, tuna) as models, but address the systems behind the loss: food, energy and finance.
- Push food and finance past their tipping points within this decade, starting with closing the US$1.3 trillion a year financing gap.
- Implement the KMGBF so that it counts biodiversity value, not only hectares, and keep the transition fair and inclusive.

GS Paper 2 link: international environmental agreements and bodies (CBD, KMGBF).
Prelims: who produces the LPI (ZSL) and who publishes the report (WWF); what “relative abundance” means; realm and region figures; IPBES regions; the Red List Index and Biodiversity Intactness Index; KMGBF Target 3; the green sea turtle’s IUCN status.
Mains: why an average decline coexists with stable or rising populations; drivers of biodiversity loss; positive tipping points as a theory of change; the 30x30 debate.
Practice question (GS3, 250 words): “The Living Planet Index shows a 73% average decline in monitored wildlife populations since 1970, yet about half the populations it tracks are stable or increasing.” Explain what the index measures, and discuss how positive tipping points in the energy, food and finance systems can help meet the Kunming-Montreal targets.
📌 Facts Corner, Knowledgepedia
Prelims, statement-ready facts:
- Living Planet Report 2026, The Science of Hope: published by WWF (Gland, Switzerland), released 8 October 2026.
- The Living Planet Index is produced by ZSL (Zoological Society of London): 35,803 populations of 5,790 vertebrate species.
- Global LPI: -73% (73.2%) from 1970 to 2022, an average fall of 2.5% a year.
- Realms: freshwater -85%, terrestrial -69%, marine -59% (the slowest).
- Regions: Latin America and the Caribbean -95%, Africa -80%, Asia and the Pacific -49%, North America -28%, Europe and Central Asia -23%.
- Most reported threat: habitat loss and degradation; then overexploitation, climate change, pollution, invasive species and disease.
- Green sea turtle: first marine turtle downlisted from Endangered to Least Concern on the IUCN Red List (2025).
- Wild tigers: 3,200 (2010) to around 5,700 (2025), an increase of over 70%.
- KMGBF (2022, under the CBD): 23 targets for 2030; Target 3: at least 30% of land, inland water, coastal and marine areas effectively conserved by 2030.
Prelims, the traps:
- 73% is not species lost and not 73% fewer animals: the LPI is the average change in relative abundance of monitored populations.
- About half the populations in the index are stable or increasing; the average falls because the losses are larger.
- The 2024 and 2026 reports both say 73%, but over different series (to 2020 and to 2022): not two years of stability.
- Regional figures cover terrestrial and freshwater populations only, not marine.
- The African savannah elephant remains Endangered overall; only some southern African populations are rising.
Mains, arguments and keywords:
- Positive tipping point: a system crosses a threshold into a healthier state and the change reinforces itself. Energy has tipped; food and finance have not.
- Keywords: relative abundance; 1970 baseline; nature-positive production; US$1.3 trillion biodiversity financing gap; whole-of-society approach; 30x30.
- Way forward: scale proven recoveries, transform food and finance within this decade, measure biodiversity value and not only protected hectares.
Interview, be ready for:
- “If half the populations are stable or rising, is the 73% alarmist?” Explain averaging of relative change, then note that three other indicators point the same way.
