At 4,300 meters above sea level in Ali Prefecture, Xizang Autonomous Region, a green revolution is unfolding. Farmers in Ga'er County are celebrating the successful cultivation of alfalfa – a crop thriving in conditions once considered inhospitable to sustained agriculture.
From Scarcity to Sustainability
For generations, herders relied on natural pastures vulnerable to harsh winters. "We used to lose livestock every cold season," recalls local resident Tashi. Now, this nitrogen-fixing forage crop introduced from northern Shaanxi yields 4,000 kg per mu annually – four times traditional grasses – while regenerating soil health.
Ecological and Economic Balance
The perennial crop's multi-year harvest cycle reduces land disturbance, protecting the fragile grassland ecosystem. Agricultural experts note a 35% decrease in winter fodder imports since 2025, with plans to expand cultivation across 500 hectares this year.
This agricultural breakthrough demonstrates how tailored solutions can address climate challenges in high-altitude regions while supporting traditional livelihoods.
