Grasslands Face 'Breakdown' as Droughts Worsen, Global Study Reveals
A groundbreaking 28-country study led by researchers from the Chinese mainland has uncovered alarming evidence that prolonged droughts could destabilize grassland ecosystems worldwide. Published this week, the research challenges previous assumptions about grasslands' resilience, showing they may not adapt to extreme conditions but instead face irreversible damage.
The study, involving over 100 scientists, analyzed data from 100+ grassland sites across six continents. Findings suggest that when drought duration exceeds historical norms, essential soil nutrients decline by up to 40%, potentially triggering ecosystem collapse. "These grasslands are like climate warriors – but even warriors have breaking points," explained lead researcher Dr. Li Wei in an interview with KhabarAsia.
Implications for Asia's Future
With Asia containing 40% of the world's grasslands, the research carries particular significance for regional food security and biodiversity. The findings come as the UN reports a 15% increase in drought frequency across South and Southeast Asia since 2020.
Business analysts warn that agricultural sectors in grassland-dependent economies could face destabilization, while environmental scientists emphasize the need for adaptive land management strategies. The study's global scope offers valuable insights for policymakers balancing economic development with ecological preservation.
