A new international study published today in PNAS warned that climate change could reduce 36-50% of the world’s climatically suitable grazing land by the end of the century, threatening the livelihoods of over 100 million pastoralists and up to 1.6 billion animals.

The study highlights that the strongest impacts will fall on already vulnerable regions, including countries facing food insecurity, economic instability, and social inequality.

“Climate change will significantly shrink the spaces where grazing systems can survive. Much of this loss will occur in regions already struggling with hunger, political instability, and gender inequity,” said Chaohui Li, lead author and former researcher at Potsdam Institute for Climate Impact Research and Peking University.

“Grassland-based grazing is highly dependent on the environment, including things like temperature, humidity, and water availability. What we see is that climate change is going to reduce the spaces in which grazing can thrive, fundamentally challenging farming practices that have existed for centuries,” commented Maximilian Kotz, another of the study’s coauthors and researcher at the Barcelona Supercomputing Center.

Meanwhile, Africa emerges as one of the most vulnerable continent. Depending on future emissions pathways, the continent could lose 16% of suitable grazing land under low-emissions scenarios, and up to 65% if fossil fuel use continues unabated. As temperature zones shift southward, key grazing regions—including the Ethiopian Highlands, the East African Rift Valley, and the Kalahari Basin—may become nonviable altogether.

“The scale of climate change we observe goes far beyond what historical adaptation strategies—such as switching livestock species or migrating herds—can handle. In many regions, especially Africa, the climatic shifts are simply too large,” said Dr Prajal Pradhan, Assistant Professor at the University of Groningen and affiliated with Wubbo Ockels School for Energy and Climate, is a co-author of the study

According to Xudong Wu (Beijing Forestry University), climate-driven changes in grazing suitability across Asia are projected to follow a distinct westward shift. 

Grazing zones are expected to move inland from their current concentration in the eastern plains toward the highland and interior regions. Suitable future niches are likely to cluster in Asian major grazing landscapes, including the Mongolian Grasslands and the Northern China Plains.

The findings underscore the urgent need for rapid emissions reductions, highlighting that limiting global warming is the most effective way to protect grazing-based livelihoods that have sustained communities for centuries.

At least four persons died in a bus accident near Manthali of Ramechhap district on Tuesday.
