From camel drivers in the Sahara to nomads on the Mongolian steppe, traditional herders the world over rely on earth’s wildest open spaces to support an ancient way of life.
But the expansive plains, tundra and savanna they inhabit are in much greater peril than previously thought, researchers said Tuesday in a major reassessment of the health of these crucial environments.
As much as half of all rangelands — encompassing some of nature’s most striking vistas from the Arctic to the tropics, deserts and mountains — are believed to be degraded, the report said.
Mostly natural grasslands used by livestock and wild animals to graze, they also include scrubland, mountain plateaus, deserts and wetlands.
Climate change, urban expansion, population growth and the conversion of land for farming was fuelling their destruction, said the report by the UN Convention to Combat Desertification (UNCCD).
Rangelands were grossly undervalued and their “silent demise” had passed mostly unnoticed despite what was at stake, said UNCCD executive secretary Ibrahim Thiaw.
“We as humanity have to pay attention to this,” he told AFP.
The “persistent loss and deterioration” of rangelands would be felt beyond the pastoralist communities who have adapted to life in these environments over centuries, the report said.
– Climate ally –
Healthy rangelands are an asset in the fight against global warming, locking away carbon in soil and spurring the growth of vegetation that pulls planet-heating CO2 from the atmosphere.
Traditional farming customs — such as rotating grazing areas and conserving scarce resources in difficult times — improved soil health and its capacity to store carbon, the report’s lead author Pedro Maria Herrera Calvo told AFP.
Poor policy, neglect and large-scale rangeland mismanagement had eroded soils, releasing carbon rather than storing it, and stripped the earth of the nutrients needed to support plant and animal life.
Rangelands are biodiversity hotspots, providing habitats for Africa’s most iconic wildlife, and pasture for one billion grazing animals, the report said.
They account for one-sixth of the world’s food production, it added, and underpin many national economies.
They are also a cultural bedrock for half a billion pastoralist people in more than 100 countries, mostly poor and marginalised communities such as the Bedouin, Fulani and Saami.
A quarter of the world’s languages are spoken among pastoral groups who call these places home.
“It is part of our heritage,” said Thiaw. “Losing it would mean not only losing ecosystems and losing the economy, but losing our own culture.”
– ‘Voiceless and powerless’ –
Yet they are barely studied, said Calvo. Rosier outlooks did not reflect reality, and this reassessment by dozens of experts was long overdue, he added.
“We feel that the actual data estimating rangelands degradation around 25 percent is severely underestimated,” he said. “We think that almost 35 -– even 50 percent –- of rangelands are already degraded.”
Rangelands cover 80 million square kilometres — more than half the land surface of earth. Protecting them would require policy that better supports the pastoralists who understand them best, the report said.
Instead of having a seat at the table however, nomadic communities were “voiceless and powerless”, the report said.
Ignoring their wisdom in sustainably managing these complex environments — or, worse still, forcing them off the land — would only condemn these wild places and their custodians to an even bleaker future, Thiaw argued.
“It is important for this to be taken much more seriously.”
‘Silent demise’ of vast rangelands threatens climate, food, wellbeing of billions: UN Convention to Combat Desertification
Rangelands cover 54% of all land; as much as 50% are degraded, imperilling 1/6th of humanity’s food supply, 1/3rd of Earth’s carbon reservoir; UNCCD report points way to restore, better manage rangelands, urges protection of pastoralism

DEGRADATION OF EARTH’S EXTENSIVE, OFTEN IMMENSE NATURAL PASTURES AND OTHER RANGELANDS DUE TO OVERUSE, MISUSE, CLIMATE CHANGE AND BIODIVERSITY LOSS POSES A SEVERE THREAT TO HUMANITY’S FOOD SUPPLY AND THE WELLBEING OR SURVIVAL OF BILLIONS OF PEOPLE, THE UN WARNS IN A STARK NEW REPORT.

Bonn/Ulaanbaatar – Degradation of Earth’s extensive, often immense natural pastures and other rangelands due to overuse, misuse, climate change and biodiversity loss poses a severe threat to humanity’s food supply and the wellbeing or survival of billions of people, the UN warns in a stark report today.
Authors of the Global Land Outlook Thematic Report on Rangelands and Pastoralists, launched May 21 in Ulaanbaatar, Mongolia by the UN Convention to Combat Desertification (and available post-embargo at www.unccd.int), say up to 50% of rangelands are degraded.
Symptoms of the problem include diminished soil fertility and nutrients, erosion, salinization, alkalinization, and soil compaction inhibiting plant growth, all of which contribute to drought, precipitation fluctuations, and biodiversity loss both above and below the ground.
The problem is driven largely by converting pastures to cropland and other land use changes due to population growth and urban expansion, rapidly rising food, fibre and fuel demands, excessive grazing, abandonment (end of maintenance by pastoralists), and policies that incentivise overexploitation.
What are rangelands?
The rangelands category of Earth’s land cover consists mostly of the natural grasslands used by livestock and wild animals to graze and forage.
They also include savannas, shrublands, wetlands, tundra and deserts.
Altogether, these lands constitute 54% of Earth’s land cover, account for one sixth of global food production and represent nearly one third of the planet’s carbon reservoir.
“When we cut down a forest, when we see a 100-year-old tree fall, it rightly evokes an emotional response in many of us. The conversion of ancient rangelands, on the other hand, happens in ‘silence’ and generates little public reaction,” says UNCCD Executive Secretary Ibrahim Thiaw.
“Sadly, these expansive landscapes and the pastoralists and livestock breeders who depend on them, are usually under-appreciated,” Mr. Thiaw adds. “Despite numbering an estimated half a billion individuals worldwide, pastoralist communities are frequently overlooked, lack a voice in policy-making that directly affects their livelihoods, are marginalised, and are even often seen as outsiders in their own lands.”
Mongolia Environment Minister H.E. Bat-Erdene Bat-Ulzii says: “As custodian of the largest grasslands in Eurasia, Mongolia has always been cautious in transforming rangelands. Mongolian traditions are built on the appreciation of resource limits, which defined mobility as a strategy, established shared responsibilities over the land, and set limits in consumption. We hope this report helps focus attention on rangelands and their many enormous values – cultural, environmental, and economic – which cannot be overstated. If these rangelands cannot support these massive numbers of people, what alternatives can they turn to?”
Mongolia will host the 17th UNCCD Conference of the Parties meeting in 2026, the International Year of Rangelands and Pastoralists (IYRP), declared by the United Nations General Assembly on Mongolia’s initiative.
Two billion people – small-scale herders, ranchers and farmers, often poor and marginalised – depend on healthy rangelands worldwide.
Indeed, in many West African states, livestock production employs 80% of the population. In Central Asia and Mongolia 60% of the land area is used as grazing rangelands, with livestock herding supporting nearly one third of the region’s population.
Ironically, the report underlines, efforts to increase food security and productivity by converting rangelands to crop production in mostly arid regions have resulted in degraded land and lowered agricultural yields.
The report calls out “weak and ineffective governance,” “poorly implemented policies and regulations,” and “the lack of investment in rangeland communities and sustainable production models” for undermining rangelands.
An innovative approach
The new report’s 60+ expert contributors from over 40 countries agree that past estimates of degraded rangeland worldwide – roughly 25% – “significantly underestimates the actual loss of rangeland health and productivity” and could be as much as 50%.
Rangelands are often poorly understood and a lack of reliable data undermines the sustainable management of their immense value in food provisioning and climate regulation, the report warns.
The report details an innovative conceptual approach that would enable policy-makers to stabilise, restore and manage rangelands.
The new approach is backed by experience detailed in case studies from nearly every world region, drawing important lessons from successes and missteps of rangeland management.
A core recommendation: protect pastoralism, a mobile way of life dating back millennia centred on the pasture-based production of sheep, goats, cattle, horses, camels, yaks, llamas or other domesticated herbivores, along with semi-domesticated species such as bison and reindeer.
Says Mr. Thiaw: “From the tropics to the Arctic, pastoralism is a desirable default and often the most sustainable option that should be incorporated into rangeland use planning.”
The economic engine of many countries
Rangelands are an important economic engine in many countries and define cultures. Home to one quarter of the world’s languages, they also host numerous World Heritage Sites and have shaped the value systems, customs and identities of pastoralists for thousands of years.
The report includes detailed analyses of individual countries and regions.
For example, livestock production accounts for 19% of Ethiopia’s GDP, and 4% of India’s.
Brazil – with over 250 million cattle -- produces 16% of the world’s beef, valued at $7.6 billion in 2019.
In Europe, many rangelands have given way to urbanization, afforestation and renewable energy production.
In the United States, large tracts of grassland have been converted to crops, while some Canadian grasslands have been left fragile by large-scale mining and infrastructure projects. There are also positive developments noted, such as growing efforts in both countries to reintroduce bison – an animal of great cultural importance to indigenous peoples – to promote rangeland health and food security.

World areas most acutely affected by rangelands degradation, ranked in descending order:
Central Asia, China, Mongolia
The replacement of government management and oversight with privatization and agricultural industrialization left herders abandoned and dependent on insufficient natural resources causing widespread degradation.
The gradual restoration of traditional and community-based pastoralism is leading to critical advances in sustainable rangeland management.”
North Africa and Near East
The impact of climate change in one of the world’s driest regions is pushing pastoralists into poverty and degrading the rangelands on which they rely.
Updated traditional institutions, such as Agdals – reservoirs of fodder used to feed animals in periods of critical need and allowing for the regeneration of natural resources – and incipient supportive policies are improving the way rangelands are managed.
Sahel and West Africa
Conflict, power balance and border issues have interrupted livestock mobility leading to rangelands degradation.
Unified policies, recognition of pastoralists’ rights and cross-border agreements are reestablishing mobility for animal herders, crucial for landscape restoration.
South America
Climatic change, deforestation linked to industrialised agriculture and extractive activities, and land use conversion are South America’s main drivers of rangeland degradation.
Multifunctionality and diversity of pastoralist systems hold the key for restoring some of the most interesting rangelands in the world, including the Pampa, the Cerrado and Caatinga savannahs, and the Puno Andean systems.
East Africa
Migration and forced displacement caused by competing uses of land (such as hunting, tourism, etc), are evicting pastoralists from their traditional lands, causing unanticipated degradation consequences.
Women-led initiatives and improved land rights are securing pastoralists’ livelihoods, protecting biodiversity, and safeguarding the ecosystem services provided by rangelands.
North America
The degradation of ancient grasslands and dry rangelands threatens the biodiversity of iconic North American ecosystems such as the tall-grass prairies or the southern deserts.
The incorporation of indigenous people to rangeland governance is a clear step to help recover these historic landscapes.
Europe
Policies favouring industrial farming over pastoralism and misguided incentives are causing rangelands and other open ecosystems to be abandoned and degraded.
Political and economic support, including legal recognition and differentiation, can turn the tide and help address critical environmental crises such as the rising frequency and intensity of wildfires and climate change.
South Africa and Australia
Afforestation, mining, and the conversion of rangelands to other uses are causing the degradation and loss of rangelands.
The co-creation of knowledge by producers and researchers, and respect for and use of traditional wisdom held by indigenous communities, open new paths for restoring and protecting rangelands.
Paradigm shift
Halting the deterioration requires a paradigm shift in management at every level – from grassroots to global, the report concludes.
Pedro Maria Herrera Calvo, the report’s lead author, says: “The meaningful participation of all stakeholders is key to responsible rangeland governance, which fosters collective action, improves access to land and integrates traditional knowledge and practical skills”.
Achieving “land degradation neutrality” (Sustainable Development Goal 15.3) – balancing the amount and quality of healthy land to support ecosystem services and food security – also requires cross-border cooperation.
Pastoralists with generations of experience in achieving life in balance with these ecosystems should help inform this process at every step, from planning to decision-making to governance, the report says.
Solutions must be tailored to the characteristics and dynamics of rangelands, which vary widely from arid to sub-humid environments, as seen in West Africa, India or South America.
The report notes that traditional assessment methods often undervalue the real economic contribution of rangelands and pastoralism, highlighting the need for the innovative approach recommended.
Among key recommendations:
- Integrated climate change mitigation and adaptation strategies with sustainable rangeland management plans to increase carbon sequestration and storage while boosting the resilience of pastoralist and rangeland communities
- Avoid or reduce rangeland conversion and other land use changes that diminish the diversity and multifunctionality of rangelands, especially on indigenous and communal lands
- Design and adopt rangeland conservation measures, within and outside protected areas, that support biodiversity above and below ground while boosting the health, productivity, and resilience of extensive livestock production systems
- Adopt and support pastoralism-based strategies and practices that help mitigate harms to rangeland health, such as climate change, overgrazing, soil erosion, invasive species, drought, and wildfires
- Promote supportive policies, full people’s participation and flexible management and governance systems to boost the services that rangelands and pastoralists provide to the whole society.

Comments
“Imbalance between the supply of and demand for animal forage lands leads to overgrazing, invasive species, and the increased risk of drought and wildfires – all of which accelerate desertification and land degradation trends around the world.”
“We must translate our shared aspirations into concrete actions - stopping indiscriminate conversion of rangelands into unsuitable land uses, advocating for policies that support sustainable land management, investing in research that enhances our understanding of rangelands and pastoralism, empowering pastoralist communities to preserve their sustainable practices while also gaining tools to thrive in a changing world, and supporting all stakeholders, especially pastoralists, to implement measures that effectively thwart further degradation and preserve our land, our communities, and our cultures.”
Maryam Niamir-Fuller, Co-Chair, International Support Group for the UN’s International Year for Rangelands and Pastoralists – 2026
For the sake of future generations and economic stability, we need to improve awareness of and safeguard the immense value of rangelands. Due to their dynamic nature, predicting the consequences of rangelands degradation on economics, ecology, and societies is challenging. Managers require authoritative insights into the response of rangelands to different disturbances and management approaches, including policy tools that better capture the broad social importance of rangelands.
Carlos Manuel Rodríguez, CEO and Chairperson, Global Environment Facility
“More than half of the world’s land mass is rangeland – and yet these landscapes and the people who inhabit and manage them have been largely neglected. They are a main source of food and feed for humanity, and yet they are also the world economy’s dumping ground. It is time to shift perspective – from ‘a rangeland problem’ to ‘a sustainable rangeland solution’.
UN International Year of Rangelands & Pastoralists (IYRP) Working Group
“Pastoralists produce food in the world’s harshest environments, and pastoral production supports the livelihoods of rural populations on almost half of the world’s land. They have traditionally suffered from poor understanding, marginalization, and exclusion from dialogue. We need to bring together pastoralists and the main actors working with them to join forces and create the synergies for dialogue and pastoralist development
UN Food and Agricultural Organization (FAO)
“To have any chance of meeting global biodiversity, climate and food security goals, we simply cannot afford to lose any more of our rangelands, grasslands and savannahs. Our planet suffers from their ongoing conversion, as do the pastoralists who depend on them for their livelihoods, and all those who rely on them for food, water and other vital ecosystem services. The Global Land Outlook reinforces that too little political attention or finance is invested in protecting and restoring these critical ecosystems. National and sub-national authorities must take place-based action to safeguard and improve the health and productivity of rangelands, grasslands and savannahs – to benefit people and planet.”
