Context of the News
The World Wide Fund for Nature (WWF) and the Zoological Society of London (ZSL) have released the Living Planet Report 2026, titled “The Science of Hope.”
The report uses the Living Planet Index (LPI) to assess changes in monitored vertebrate populations. It reports an average 73.2% decline in monitored vertebrate population abundance between 1970 and 2022.
At the same time, the report highlights that targeted conservation can reverse wildlife decline. India provides several examples of such recovery.
Background
What is the Living Planet Index?
The Living Planet Index (LPI) is an indicator that tracks changes in the relative abundance of monitored vertebrate populations over time.
It is important to understand what the index does not measure.
A 73.2% decline in the LPI does not mean that 73.2% of all animals have disappeared.
Instead, it means that the average relative abundance of the populations included in the index has declined by that amount.
The LPI is therefore an indicator of population trends, rather than a direct count of total animals or species.
Why is biodiversity important?
Biodiversity refers to the variety of life at three broad levels:
- Genetic diversity — variation within a species.
- Species diversity — variety of species in an ecosystem.
- Ecosystem diversity — variety of ecosystems and habitats.
India is particularly important from a biodiversity perspective. It occupies only about 2.4% of the world’s geographical area, but supports nearly 8% of globally known species and is recognised as one of the world’s megadiverse countries.
News Breakdown
Global Wildlife Populations Show a Sharp Decline
The Living Planet Report 2026 presents a serious picture of global biodiversity.
The average abundance of monitored vertebrate populations declined by 73.2% between 1970 and 2022.
This is an average population-level decline, not a statement that most species have become extinct.
Major findings
| Indicator | Finding |
| Period covered | 1970–2022 |
| Average decline in monitored vertebrate populations | 73.2% |
| Average annual decline | About 2.5% |
| Freshwater populations | 85% decline |
| Terrestrial populations | 69% decline |
| Marine populations | 59% decline |
Around half of the monitored populations remain stable or are increasing. However, severe declines in other populations pull down the overall index.
Freshwater Ecosystems Face the Greatest Decline
Among the major ecosystem categories, freshwater ecosystems recorded the steepest decline.
Freshwater biodiversity is particularly vulnerable because rivers, lakes and wetlands face several pressures simultaneously.
Major pressures include:
- Habitat fragmentation caused by dams and infrastructure.
- Water extraction for agriculture and human consumption.
- Pollution from urban, industrial and agricultural sources.
- Alteration of natural river flows.
- Destruction and degradation of wetlands.
This makes freshwater conservation important not only for biodiversity but also for water security, agriculture and human livelihoods.
Regional Trends Show Major Differences
The decline is not uniform across the world.
| Region | Decline in monitored populations |
| Latin America and Caribbean | 95% |
| Africa | 80% |
| Asia-Pacific | 49% |
| North America | 28% |
| Europe and Central Asia | 23% |
However, these numbers should not be interpreted as a simple ranking of which regions have the healthiest ecosystems.
The baseline year matters.
Significant biodiversity loss had already occurred in parts of North America and Europe before 1970. Therefore, a smaller decline after 1970 does not necessarily mean that these regions have experienced less overall biodiversity loss.
What is Driving Biodiversity Loss?
The report identifies several major drivers of wildlife decline.
1. Habitat Loss and Degradation
Habitat loss occurs when natural habitats are converted or destroyed.
It is the largest reported driver, accounting for around 30% of the identified pressure.
Agricultural expansion is a major cause of habitat conversion.
2. Overexploitation
Overexploitation means using biological resources faster than their populations can naturally recover.
It contributes about 23% of the identified pressure.
Examples include:
- Overfishing.
- Unsustainable hunting.
- Illegal wildlife trade.
- Excessive harvesting of biological resources.
3. Climate Change
Climate change accounts for around 14% of the identified pressure.
It can affect wildlife through:
- Changing temperature regimes.
- Altering rainfall patterns.
- Increasing extreme weather events.
- Changing species distribution.
- Affecting food and breeding cycles.
- Increasing the frequency or intensity of ecosystem disturbances.
Together, habitat loss and degradation, overexploitation and climate change account for roughly two-thirds of the identified pressures.
The Report Also Highlights Hope
The report does not present biodiversity conservation only as a story of decline.
It also identifies successful conservation interventions.
This is important for UPSC because it demonstrates that biodiversity loss is not necessarily irreversible.
Examples of species showing recovery following targeted interventions include:
- Green turtles
- Bluefin tuna
- Southern African elephants
- Wild tigers
The central lesson is that scientific monitoring, habitat protection, regulation, community participation and sustained financing can produce measurable conservation gains.
What are Positive Tipping Points?
A positive tipping point is a stage at which a sustainable technology, practice or behaviour gains enough momentum to produce rapid and self-reinforcing transformation.
The report identifies three broad phases of systemic transformation:
| Phase | Meaning |
| Enabling | Conditions are being created for wider transformation |
| Accelerating | Adoption is expanding rapidly |
| Stabilising | The new sustainable system becomes established |
The report identifies energy as being in the accelerating phase, while food and finance require faster progress.
The broader message is that biodiversity conservation cannot be separated from the way societies produce energy, food and finance.
Why Does Biodiversity Loss Matter to the Economy?
Nature is not only an environmental asset.
It also provides ecosystem services.
Ecosystem services are the benefits that people obtain from ecosystems.
They include:
- Pollination.
- Water purification.
- Soil formation.
- Climate regulation.
- Fisheries.
- Flood regulation.
- Carbon storage.
A major economic implication is that a substantial share of global economic activity depends on functioning natural systems.
Therefore, biodiversity loss can become a problem of economic security, food security and livelihood security.
India: A Biodiversity-Rich Country
India is one of the world’s megadiverse countries.
Despite occupying only 2.4% of global land area, India supports nearly 8% of globally known flora and fauna according to government biodiversity documentation.
India’s biodiversity importance is linked to its wide geographical and climatic diversity.
It contains:
- Himalayan ecosystems.
- Tropical forests.
- Grasslands.
- Deserts.
- Wetlands.
- Coastal ecosystems.
- Islands.
- Marine ecosystems.
India also contains parts of four global biodiversity hotspots:
- Himalaya
- Indo-Burma
- Western Ghats–Sri Lanka
- Sundaland through the Nicobar Islands.
India Shows That Wildlife Recovery Is Possible
India’s conservation experience provides several examples of species recovery.
Tiger Conservation
Project Tiger was launched in 1973 to protect India’s tiger populations and their habitats.
The 2022 All India Tiger Estimation estimated India’s tiger population at 3,682, with an estimated range of 3,167–3,925.
India now supports roughly 70% of the world’s wild tiger population according to the National Tiger Conservation Authority.
The tiger recovery demonstrates the importance of:
- Protected areas.
- Scientific population estimation.
- Anti-poaching measures.
- Habitat management.
- Landscape-level conservation.
Snow Leopard Conservation
India conducted its first nationwide scientific assessment of snow leopards under the Snow Leopard Population Assessment in India (SPAI) programme.
The assessment estimated 718 snow leopards in India.
The exercise covered more than 70% of the potential snow leopard range and used field surveys, occupancy assessment and camera trapping.
The estimated distribution included:
| Region | Estimated population |
| Ladakh | 477 |
| Uttarakhand | 124 |
| Himachal Pradesh | 51 |
| Arunachal Pradesh | 36 |
| Sikkim | 21 |
| Jammu and Kashmir | 9 |
The assessment demonstrates the growing role of technology and scientific monitoring in wildlife conservation.
Cheetah Reintroduction
Project Cheetah aims to restore the cheetah to India after its historical extinction from the country.
The project involves the translocation of cheetahs from Africa to India and represents an important experiment in species restoration.
It also highlights the difference between species reintroduction and conventional population protection.
- Protection focuses on conserving an existing population.
- Reintroduction attempts to establish a population where the species has become locally extinct.
Dugong Conservation
India has established the Dugong Conservation Reserve in Palk Bay, Tamil Nadu, covering about 448 sq km.
A conservation reserve is a protected area category under India’s wildlife protection framework that can also provide space for conservation involving local communities.
The Palk Bay reserve is particularly significant because the dugong is a threatened marine mammal dependent on coastal and seagrass ecosystems.
Conservation Is Not Limited to Charismatic Species
A major challenge in wildlife policy is the tendency to prioritise highly popular animals such as:
- Tiger.
- Elephant.
- Lion.
- Rhino.
These are often called charismatic species because they attract substantial public attention and conservation funding.
However, less prominent species also perform critical ecological functions.
India therefore needs dedicated conservation financing for species such as:
- Dugong
- Great Indian Bustard
- Caracal
- Mahseer
- Lion-tailed macaque
- Hornbills
This is where instruments such as dedicated species conservation funds can become important.
Major Challenges for India’s Wildlife
1. Habitat Fragmentation
Habitat fragmentation occurs when a large continuous habitat is divided into smaller and isolated patches.
Roads, railways, canals and other linear infrastructure can fragment wildlife habitats.
This can:
- Restrict animal movement.
- Reduce genetic exchange.
- Increase road and railway mortality.
- Isolate populations.
- Increase human-wildlife conflict.
Therefore, conservation must increasingly move from isolated protected areas towards connected wildlife landscapes and corridors.
2. Human-Wildlife Conflict
Human-Wildlife Conflict (HWC) occurs when interactions between people and wildlife result in negative consequences for people, wildlife or both.
As wildlife populations recover and natural habitats become fragmented, animals can increasingly enter agricultural and settlement areas.
This may result in:
- Crop damage.
- Livestock loss.
- Human injury or death.
- Retaliatory killing of animals.
Therefore, successful wildlife recovery must be accompanied by conflict mitigation and community participation.
3. Invasive Alien Species
An invasive alien species is a non-native species that establishes itself and causes ecological or economic harm.
Examples relevant to Indian ecosystems include:
- Lantana camara
- Prosopis juliflora
These species can alter vegetation structure and compete with native plants.
4. Illegal Wildlife Trade
Illegal wildlife trade continues to threaten several species.
Species such as pangolins, star tortoises and certain birds are targeted for illegal trade.
The challenge is increasingly linked with organised criminal networks, requiring cooperation between wildlife authorities, police, customs agencies and international organisations.
5. Climate Change
Climate change is increasingly altering wildlife habitats.
Its impacts include:
- Changing rainfall patterns.
- Increasing heat stress.
- Forest fires.
- Sea-level rise.
- Shifts in species ranges.
- Changes in breeding and migration patterns.
Species confined to specialised habitats may be particularly vulnerable because they have fewer opportunities to shift their range.
How Can India Strengthen Wildlife Conservation?
Integrate Conservation with Infrastructure Planning
Wildlife corridors should be considered during the planning of highways, railways, canals and other infrastructure.
Tools such as GIS-based habitat mapping, wildlife crossings and landscape-level planning can reduce fragmentation.
Strengthen Community Participation
Local and indigenous communities should be treated as partners in conservation, rather than merely as beneficiaries or restrictions imposed upon them.
Community-based conservation can improve:
- Monitoring.
- Conflict management.
- Habitat protection.
- Sustainable resource use.
Improve Conservation Financing
Wildlife conservation requires long-term funding.
Financial resources should not be concentrated only on famous species.
Dedicated funding can support lesser-known but ecologically important species.
Use Technology for Monitoring
Modern conservation increasingly depends on:
- Camera traps.
- Radio-collaring.
- Geographic Information System (GIS) mapping.
- Drones and remote sensing.
- Digital patrolling.
- Wildlife forensics.
The objective should be to combine technology with field-based ecological knowledge.
Align National Action with Global Biodiversity Goals
India’s biodiversity policies need to remain aligned with the Kunming-Montreal Global Biodiversity Framework (KMGBF).
A major KMGBF objective is the 30×30 target, which seeks to effectively conserve and manage at least 30% of the world’s terrestrial, inland water, coastal and marine areas by 2030.

Answers and Explanations
Question 1 — (b) 1 and 3 only
- Statement 1 is correct: The LPI tracks changes in the relative abundance of monitored vertebrate populations.
- Statement 2 is incorrect: A decline in the index does not mean an equivalent percentage of animals or species has disappeared.
- Statement 3 is correct: The index is designed to identify population abundance trends over time.
Question 2 — (c) Only three
- Pair 1 is correct: Project Tiger was launched in 1973.
- Pair 2 is correct: The Snow Leopard Population Assessment in India was India’s first nationwide scientific assessment of the species.
- Pair 3 is correct: The Dugong Conservation Reserve is located in Palk Bay, Tamil Nadu and covers about 448 sq km.
- Pair 4 is incorrect: Project Cheetah involves translocation of cheetahs from Africa to India; it is not simply protection of an existing indigenous population.

- Statement-I is correct: A lower post-baseline decline cannot automatically be interpreted as lower cumulative historical biodiversity loss.
- Statement-II is correct: The LPI compares population trends against its defined historical baseline.
- Therefore, earlier biodiversity losses that occurred before the baseline period can affect how later regional trends should be interpreted.
Key Takeaway for UPSC
The Living Planet Report 2026 is important because it connects biodiversity loss, ecosystem services, economic systems and conservation governance. For the Mains examination, the key theme is not merely wildlife decline but the question of how scientific conservation and institutional action can reverse ecological degradation.
“Conservation is not about preserving the past; it is about securing the future.”
