New atlas reveals climate-critical rangelands cover half the world’s land surface, supporting millions of people and critical ecosystems— yet often ignored despite threats

May 26, 2021

Rangelands Atlas launched by the Rangelands Initiative and ILRI, FAO, IUCN, UNEP, WWF

● 54 per cent of the world’s terrestrial surface consists of rangelands, but just 10 per cent of national climate plans (as part of the Paris Climate Agreement) include references to rangelands. 

● New rangelands atlas can guide climate and biodiversity negotiators ahead of UN summits

● Despite their importance to climate, nature and people, rangelands are threatened with escalating  conversion and drastic effects of climate change  

A new atlas published today shows that 54 per cent of the world’s land surface consists of vast  tracts of land covered by grass, shrubs or sparse, hardy vegetation that support millions of pastoralists, hunter  gatherers, ranchers and large populations of wildlife--and store large amounts of carbon. Yet while most climate  plans focus on forests, much less importance is given to rangelands, leaving this massive planetary ecosystems  supporting people and nature exposed to a wide variety of threats.  

"The atlas is a valuable tool to gather data and to experiment with participatory forms of mapping, together with  the pastoralist communities on the ground. The world's pastoralists - estimated to be over 200 million people - need to be heard, supported and recognized for their role in caring and sustainably managing rangelands, and  therefore must be part of the solution to the critical environmental situation that we find ourselves in." – Fernando  García Dory, Pastoralists Focal Point, Rangelands Initiative

This is among the key conclusions of the new Rangelands Atlas—an ambitious, first of its kind inventory compiled  by a coalition of prominent international environmental, conservation and agricultural organisations cataloguing  the contemporary character of the world’s rangelands, which include the Mongolian steppe, the savannas of  Africa, the pampas of South America and the Great Plains of North America.  

The goal is to make rangelands a prominent part of policy discussions around everything from confronting  climate change to reducing poverty, managing threats to biodiversity and freshwater, and developing sustainable  food systems.  

“For the first time ever, we have an accurate understanding of how much of our planet’s land is covered by  rangelands. So far, conservation and development efforts have focused mostly on forests – we now know that  rangelands should also receive increased attention,” said Shirley Tarawali, assistant director general of the  International Livestock Research Institute (ILRI), which collaborated on the Rangeland Atlas. 

The diversity and importance of rangeland environments is mirrored in the diversity and prestige of the report’s  authors. In addition to ILRI, they include the International Union for Conservation of Nature, the World Wide  Fund for Nature, UN Environment Programme and the International Land Coalition, with contributions from the  Food and Agriculture Organization of the United Nations. 

Until now, rangelands have rarely featured on international agendas. Just 10 per cent of national climate plans  (as part of the Paris Climate Agreement) include references to rangelands, compared to 70 per cent of those  plans including references to forests. Rangelands are known to play a key role in storing carbon, providing habitat  for diverse wildlife and nature, and supporting the world’s largest rivers and wetlands. A key reason they have  been underappreciated is the lack of definitive data capturing their size and value.  

“Rangelands include some of the earth’s most precious habitats and biodiversity and they support the livelihoods  of millions of pastoralists who have a strong tradition of nature conservation. This Atlas provides the long-awaited  evidence that rangelands need to be greatly elevated as an investment and policy priority in order to achieve  sustainable development worldwide.” – Jonathan Davies, International Union for Conservation of Nature Global  Coordinator, Global Drylands Initiative 

The Rangelands Atlas helps to fill that void and will be regularly updated. It captures key elements of the  importance of rangelands, a large portion of which are dry, desert-like areas, for supporting people, wildlife and  vegetation. For example, 70 per cent of Mongolia is rangelands. In Chad, grazing livestock across remote tracts  of parched rangelands accounts for 11 per cent of GDP. The Northern Great Plains in the United States are one of the world’s four remaining intact temperate grasslands, supporting a menagerie of plants, birds and reptile  species and providing home to several Native American nations. But the atlas reveals that due to threats,  including large-scale industrial agriculture, these lands are being lost at a faster rate than the destruction of the  Amazon rainforest.  

“This preliminary set of maps fills in key data gaps about rangelands and pastoralism for key stakeholders and  decisions makers as they work toward sustainable rangelands and pastoralism. The maps will also contribute to  the UN Decade on Ecosystem Restoration (2021-2030), to help inform decisions around prioritizing where  restoration should take place in rangeland areas." – Abdelkader Bensada, UN Environment Programme’s focal  point on Pastoralism, Grasslands and Rangelands and Programme Management Officer in the Terrestrial  Ecosystem Management Unit 

To date, 12 per cent of rangelands are designated as protected areas. Much of the rest is threatened from  escalating conversion, particularly for croplands. The atlas shows that in the past three centuries more than 60  per cent of wildlands and woodlands have been converted – an area larger than North America - and an area  approximately the size of Australia (7.45 million km2) is now used to produce crops. This land-use change contributes to the climate crisis, but the atlas shows rangelands will also suffer from global warming. Drastic  effects are predicated in an area twice the size of Europe, with nature being dangerously destabilized and the  ability to produce food, fuel and fibre being reduced. 

“If we’re to have any chance of achieving climate, nature and food goals, the management and use of rangelands  must be addressed at the highest levels. Our hope is that rangelands will be included at upcoming UN conferences  on biodiversity, climate, land and food,” added Tarawali, who is also the chair of the FAO-hosted Global Agenda  for Sustainable Livestock (GASL)

In the second half of 2021, government leaders will participate in annual conferences for the three Rio Conventions, on climate change (UNFCCC), biodiversity (UNCBD) and desertification (UNCCD), along with the first  ever UN Food Systems Summit. Published ahead of the 5 June launch of the UN Decade of Ecosystem Restoration, the atlas can help guide governments, international organisations, NGOs and donors on restoring, protecting and  better managing rangelands. 

“Rangelands help keep carbon in the ground and offer necessary space for renewable energy like wind and solar,  whilst hosting diverse ecosystems and endemic species. This makes them important for the three Rio Conventions  and ultimately for achieving the SDGs. We must protect and restore rangelands while securing the livelihoods for millions of people, including pastoralists who are the custodians of these lands. The Atlas can guide all these  endeavors.” – Badi Besbes, Head Animal Production and Genetics Unit, Animal Production and Health Division,  FAO 

The Rangelands Atlas consists of preliminary maps that are a starting point for gathering more detailed data on the exact ecosystem services and economic and social benefits that rangelands deliver to people and nature. The Rangelands Atlas is available here. 

“To date, conservation and development efforts have focused on forests, overlooking other valuable ecosystems.  This atlas shows us, for the first time ever, the extent of our rangelands and highlights that we must stop  neglecting them if we are to address the world’s climate and nature crises, whilst sustainably meeting global food  demand. The protection, management and restoration of the rich and varied ecosystems of rangelands is  fundamental and their relevance must be reflected within global conservation agendas.” – Karina Berg, Global  Grasslands and Savannahs Initiative Lead, WWF
