A recent study from the Potsdam Institute for Climate Impact Research (PIK) reveals a chilling forecast for grassland-based grazing systems. These systems cover a third of our planet and are vital for millions of pastoralists and billions of livestock.
This research shows that by the year 2100, up to 50% of currently suitable grazing land might lose its viability due to rising global temperatures. This could severely impact over 100 million pastoralists and nearly 1.6 billion grazing animals.
The study, published in the journal PNAS, defines a “safe climatic space” for the grazing of cattle, sheep, and goats. Currently, these systems can thrive in a specific range of temperatures, rainfall levels, and humidity. However, climate change is set to shrink these suitable areas significantly.
Chaohui Li, the lead author of the study, pointed out that many countries already face hunger, economic issues, and political instability. These regions will suffer the most as climate change disrupts traditional grazing areas.
Maximilian Kotz, another coauthor, emphasized the heavy link between grazing and its environment. As climate conditions change, the farming practices that have sustained communities for centuries will be pushed to the brink.
Africa stands out as a hotspot for these changes. The continent could see a reduction of up to 65% of its grasslands if fossil fuel usage continues to rise. Regions crucial for grazing, like the Ethiopian Highlands and the Kalahari Basin, might no longer support livestock as temperatures shift.
“Ineffective adaptation strategies,” warns Prajal Pradhan from the University of Groningen, “like changing animal species or migrating herds, may no longer work due to the scale of these changes.”
Li also advocates for an urgent switch to renewable energy to protect livestock farming from these looming threats.
This research highlights a critical moment for global agriculture. As the climate continues to change, the challenge will not only be about adapting but about survival.
