Migratory animals worldwide are sending an urgent warning about the climate crisis, as outlined in a new report from a United Nations-backed workshop in Edinburgh convened by the Convention on the Conservation of Migratory Species of Wild Animals (CMS). Drawing from February’s gathering of 73 scientists, wildlife managers, and intergovernmental agency representatives, the report details an alarming escalation in the pressures facing species that have relied on ancient migration routes for survival.

The evidence is stark and affects all migratory groups. Warming, extreme weather, and altered water systems are “affecting migratory species across the board, altering ranges, shrinking habitats, and threatening ecosystem service delivery,” the report states. In Alaska and the Arctic, for instance, shorebirds now see fatal mismatches between their chick-rearing and the seasonal emergence of insects, with “every degree change shifting nesting time by 12 days,” leaving chicks hungry and vulnerable. Over the past decade, cooling spells have also delayed nesting by up to five days, causing birds to lay fewer, smaller eggs, further reducing their chances of survival.

Meanwhile, Asian elephants are grappling with what scientists describe as “habitat gridlock” as both climate and land-use changes push their ranges east—without sufficient forest corridors for the animals to follow, most elephants in India and Sri Lanka are left with nowhere to go, resulting in escalating encounters with human communities. Whales, too, are facing new risks as changing ocean temperatures send them off their traditional routes and diminish their food sources. The North Atlantic right whale, for example, has been identified as especially at risk, with warming seas “forcing dangerous detours.” In the rivers and seas of South America and the Mediterranean, heatwaves are killing off dolphins and slashing whale and dolphin habitat, compounding other human-caused threats.

The danger isn’t limited to charismatic megafauna. The CMS report notes how Himalayan species like musk deer, pheasants, and snow trout are being forced upslope into “smaller, fragmented refugia,” while small mammals could lose over half their range. Coastal carbon sinks such as seagrass meadows—which anchor fisheries and help trap nearly 20 percent of the world’s oceanic carbon—are under siege from marine heatwaves, cyclones, and rising seas, placing even more stress on communities dependent on these environments.

Amid these dire trends, CMS Executive Secretary Amy Fraenkel used the release to sound a public call to action. “Migratory animals are the planet’s early-warning system and they are in trouble,” Fraenkel said in a media statement. “From monarch butterflies vanishing from our gardens to whales veering off course in warming seas, these travellers are sending us a clear signal. Climate change is having impacts now, and without urgent action, the survival of such species is in jeopardy”.

Experts highlighted promising approaches to help species adapt, such as ecological corridors for land animals and dynamic management of marine migrations. “Case studies are pointing to key actions to help species adapt to climate change,” said Dr. Des Thompson, Scientific Councillor for Climate Change, in a media statement.

“We need to share examples of successful work and practices, and this is especially important where we can work with Indigenous Peoples and traditional knowledge holders to devise community-based solutions”. Dr. Thompson emphasized that “climate change compounds these problems, with greater extremes in weather affecting habitats and food resources, ecosystem services such as carbon capture, and the ranges migratory species occupy”.

The workshop’s findings, which will guide recommendations at the next major UN convention meeting in Brazil, call for closer alignment between climate and biodiversity policies worldwide and stress the necessity of unprecedented international cooperation and funding. As the CMS report makes clear, the fate of migratory species is intertwined with the environmental health of the entire planet—and their struggles echo a warning for all of humanity

Ecosystem restoration efforts are expanding across the world, but progress remains insufficient to meet global biodiversity targets for 2030, according to a new report released by the Food and Agriculture Organization of the United Nations (FAO), the United Nations Environment Programme (UNEP) and the Secretariat of the Convention on Biological Diversity (SCBD).

The report, Restoration Progress Report: Nature’s Comeback – Scaling Ecosystem Restoration for People and Planet, documents approximately 252 million hectares of terrestrial, freshwater, marine and coastal ecosystems under restoration across 149 countries in 2026. Despite this progress, the report warns that implementation must triple to achieve the global commitment to restore 30 per cent of degraded ecosystems by 2030.

Countries have collectively committed to restoring approximately one billion hectares through national plans, international agreements and regional initiatives. However, the documented restoration area represents only about a quarter of these commitments, highlighting the gap between political ambition and action on the ground.

The assessment comes as the United Nations Decade on Ecosystem Restoration (2021–2030) enters its second half. It examines restoration progress across different ecosystems, the financial resources required and the measures needed to accelerate recovery.

The report identifies land-use change, agricultural expansion, deforestation, overexploitation of natural resources, pollution and climate change as major drivers of ecosystem degradation. These pressures frequently interact, making recovery more difficult and expensive.

More than 1.56 billion hectares of land, representing over 15 per cent of the global land surface, are estimated to be degraded. Between 2015 and 2019, at least 100 million hectares of previously healthy and productive land were degraded annually. Agricultural lands account for more than 60 per cent of global land degradation, with an estimated 480 million hectares of cropland and 560 million hectares of pastureland affected.

Freshwater and marine ecosystems lag behind

Restoration progress varies considerably across ecosystem types. Terrestrial ecosystems account for the largest share of documented restoration, with approximately 232 million hectares under restoration. However, this still represents only about half of the 469 million hectares estimated to be required to meet the 2030 restoration target for terrestrial ecosystems.

Freshwater ecosystems face a substantially larger implementation gap. Only around 11 million hectares are documented as being under restoration, representing approximately 4.5 per cent of the estimated 244 million hectares required to meet the target.

Marine and coastal ecosystems have approximately 5.7 million hectares under restoration, equivalent to around 23 per cent of their estimated 25 million-hectare target.

The report notes that freshwater and marine ecosystems are among the most rapidly degrading environments, despite their importance in supporting biodiversity, food security and livelihoods. Incomplete monitoring and inconsistent national reporting also make it difficult to establish the full extent of restoration activities in these ecosystems.

Funding gap threatens restoration ambitions

Financing remains another major obstacle. Global restoration investments reached approximately $64 billion in 2022, but annual funding needs to increase to $296 billion by 2030 and $448 billion by 2050 to meet restoration requirements.

The report calls for greater public investment alongside private and blended financing mechanisms. It also stresses the need to redirect financial flows and subsidies that encourage unsustainable resource use and contribute to environmental degradation.

Beyond ecological benefits, restoration could generate significant employment opportunities. The report estimates that more than one million green jobs have been created through the World Restoration Flagships, while ecosystem restoration has the potential to generate over 32 million additional jobs globally by 2030.

It also highlights the potential of restoration to address climate change and biodiversity loss. Research cited in the assessment indicates that restoring just 15 per cent of global priority areas could capture and store carbon equivalent to 30 per cent of the total increase in atmospheric carbon dioxide since the Industrial Revolution, while helping avoid 60 per cent of species extinctions.

The report emphasises that successful restoration requires more than increasing the area of land brought under recovery. It calls for greater participation of Indigenous Peoples and local communities, recognition of land rights, stronger monitoring systems and restoration strategies that address entire landscapes and ecosystems.

As the 2030 deadline approaches, the assessment identifies three priorities for accelerating progress: building a broader global movement for restoration, strengthening political commitment and developing the technical capacity needed to implement and monitor restoration programmes.

It concludes that restoration targets must translate into sustained ecological recovery rather than remain numerical commitments. Preventing further degradation and ensuring that restored ecosystems continue to recover will be essential to securing long-term benefits for biodiversity, climate resilience and human well-being.

Greener Forests, Weaker Carbon Sinks? Study Finds Declining Productivity in Northeast India

A 24-year satellite-based study finds that Northeast India’s forests are experiencing declining carbon productivity despite relatively stable canopy cover, highlighting how rising atmospheric dryness could weaken their capacity to absorb and retain carbon.

Forests in Northeast India are showing signs of a weakening capacity to accumulate carbon despite maintaining relatively stable canopy cover, according to a study published in Ecological Indicators in October 2026. The research suggests that increasing vegetation greenness does not necessarily indicate stronger carbon sinks, highlighting the need to assess forest health beyond satellite measurements of green cover.

Titled Are Greener Forests Stronger Carbon Sinks? Rising Vapour Pressure Deficit Instigates Greening-Productivity Decoupling in a Tropical Biodiversity Hotspot in India, the study examined forest carbon dynamics across Northeast India using 24 years of satellite-derived data from 2001 to 2024.

Researchers analysed three indicators: Leaf Area Index (LAI), Gross Primary Productivity (GPP) and Net Primary Productivity (NPP). These measurements helped assess changes in forest canopy structure, photosynthetic activity and the amount of carbon retained in plant biomass after accounting for plant respiration.

The analysis found that while canopy structure remained relatively stable and gross primary productivity increased modestly by 1.76 grams of carbon per square metre annually, net primary productivity declined by 0.83 grams of carbon per square metre annually across much of the region.

The researchers identified a divergence between canopy greenness and carbon productivity across approximately 40% of forested areas. A separate divergence between photosynthetic activity and net productivity was observed across around 30% of the region.

These findings indicate that forests can maintain their green appearance without achieving corresponding gains in carbon accumulation.

Atmospheric dryness emerges as a major factor

The study identified rising Vapour Pressure Deficit (VPD) as a primary driver of declining forest productivity. VPD measures the difference between the amount of moisture the atmosphere can hold and the moisture it actually contains. Higher VPD indicates greater atmospheric demand for water, increasing stress on vegetation.

Under such conditions, plants may close their stomata, the small pores on their leaves, to reduce water loss. This also restricts the intake of carbon dioxide required for photosynthesis, potentially reducing the amount of carbon absorbed by vegetation.

The researchers also identified a major shift in forest carbon functioning beginning around 2012. Their analysis suggests that the relationship between canopy structure, photosynthesis and net carbon accumulation has weakened over time.

The findings are particularly significant for Northeast India, which the study identifies as a climatically sensitive biodiversity hotspot containing approximately one-third of India’s forest carbon.

Earlier research points to similar concerns

The findings build on earlier research published in Scientific Reports in December 2023, which examined vegetation productivity across India between 2001 and 2019.

That study found that India’s Leaf Area Index increased by 6.75% in consistently forested areas, while Net Primary Productivity declined by 6.19%. Northeast India, the Western Ghats and parts of Peninsular India emerged as important regions experiencing declining productivity.

The 2023 research associated these changes with rising temperatures, which can reduce photosynthesis and increase plant respiration beyond certain temperature thresholds.

Another study examining a semi-deciduous forest in Kaziranga, published in Agricultural and Forest Meteorology in 2022, demonstrated how carbon exchange varies with seasonal and climatic conditions. It found that the forest functioned as a carbon sink during the pre-monsoon season but as a carbon source during winter in the observed study period.

Together, these studies highlight the importance of examining forest productivity, atmospheric conditions and seasonal carbon exchange rather than relying solely on changes in green cover.

The latest research does not suggest that Northeast India’s forests are structurally collapsing. Instead, it points to a less visible change in their ecological functioning, with implications for forest carbon accounting and climate-resilient forest management.

The findings underline the need for monitoring systems that combine satellite observations with measurements of atmospheric stress and carbon productivity to better understand how tropical forests respond to a warming climate.

252 Million Hectares Under Restoration Across 149 Countries, but UN Warns of 2030 Target Gap

A UN report finds that 252 million hectares across 149 countries are under ecosystem restoration. However, increased investment and accelerated action are needed to meet global restoration targets by 2030.

Global efforts to restore degraded ecosystems have reached 252 million hectares across 149 countries, generating more than one million green jobs. However, a new United Nations assessment warns that restoration efforts remain insufficient to meet international biodiversity targets by 2030, calling for a more than fourfold increase in annual investment.

The findings are presented in the Restoration Progress Report: Nature’s Comeback – Scaling Ecosystem Restoration for People and Planet, released on October 29, 2026, by the United Nations Environment Programme (UNEP), the Food and Agriculture Organization (FAO) and the Secretariat of the Convention on Biological Diversity (CBD).

The report provides the first comprehensive global assessment of progress towards commitments to restore approximately one billion hectares of degraded ecosystems. These commitments are linked to the UN Decade on Ecosystem Restoration (2021–2030) and the Kunming-Montreal Global Biodiversity Framework, which calls for at least 30 per cent of degraded terrestrial, freshwater, marine and coastal ecosystems to be under effective restoration by 2030.

According to the assessment, the 252 million hectares currently documented under restoration represent the largest recorded global restoration effort. However, this accounts for only 34 per cent of the indicative global benchmark associated with the 2030 target.

Freshwater and marine ecosystems lag behind

The report identifies considerable differences in restoration progress across regions and ecosystem types. Asia accounts for the largest share of documented restoration, with 192.2 million hectares, followed by Africa with 36.3 million hectares and Europe with 9.1 million hectares. North and Central America account for 5.8 million hectares, South America 5.4 million hectares and Oceania 3.2 million hectares.

However, the report cautions that these figures should not be interpreted as a ranking of restoration performance, as they also reflect differences in regional land area and monitoring and reporting capacities.

Restoration of terrestrial ecosystems has reached nearly half of the global 2030 target. China reports the largest terrestrial restoration area, with 127.4 million hectares, while substantial restoration activities have also been documented in Mongolia and Kazakhstan.

Progress remains considerably slower in freshwater, marine and coastal ecosystems, despite these environments experiencing rapid degradation.

The assessment documents 11 million hectares of freshwater ecosystems under restoration across 62 countries and 5.7 million hectares of marine and coastal ecosystems across 46 countries. The report also notes that limited monitoring and reporting may mean that actual restoration activities in these ecosystems are higher than the documented figures.

Meanwhile, the share of countries reporting implemented wetland restoration or rehabilitation programmes has increased from 8 per cent in 2022 to 54 per cent.

Restoration financing needs to increase fourfold

Insufficient investment remains a major obstacle to achieving global restoration commitments. The report estimates that annual restoration financing must increase from US$64 billion to US$296 billion by 2030, representing more than a fourfold rise.

Agroforestry requires the largest estimated annual investment, at US$87 billion, followed by restorative reforestation at US$52 billion, peatland restoration at US$44 billion and seagrass restoration at US$28 billion.

The report identifies employment generation as another potential benefit of scaling up restoration. While more than one million green jobs have already been associated with restoration initiatives, increased global investment could generate up to 32 million additional jobs by 2030.

It also highlights the potential contribution of ecosystem restoration to climate mitigation and biodiversity protection. Research cited in the assessment indicates that restoring just 15 per cent of global priority areas could capture and store 30 per cent of carbon dioxide-equivalent emissions released since the Industrial Revolution and help prevent 60 per cent of projected species extinctions.

The report further identifies the participation and leadership of Indigenous Peoples and local communities as essential to ensuring long-term restoration outcomes. Secure land rights, stronger monitoring systems and sustained political commitment are among the priorities identified.

With five years remaining in the UN Decade on Ecosystem Restoration, the assessment calls on governments to move beyond isolated restoration projects towards coordinated, long-term programmes that address the underlying causes of ecosystem degradation.

It emphasises that the 2030 targets should serve as a milestone in the restoration process rather than its conclusion, as ecological recovery requires sustained action and investment beyond the end of the decade.
