In the Eurasian steppe, the Sogad Virgin Lands Campaign of thee 1950s andd 1960s plowed millions of hectares; today, Ukraine and disa have lost over 70% of their original steppe area.

Overgrazing also reduces the ability of steppes to capture andstore store carbon, increbating climate change. Restoring degraded steppes often requires activement: rotational grazing, limiting stocking rates, and reseeding g nativa species. However, these measures are difficut to implement in regions where herders depend on maximum short term output to contribute.
Climate Change andShifting Ecotone
Climate change is altering the fundamentaltal conditions that sustain steppe ecosystems. Rising temperatures, changing precipitation parafartns, and more frequent extreme events - droughs, heatwaves, and wildfires - are already being observed across steppe regions.
