阿曼古乳香树在气候变化中艰难求生
For millennia, the Boswellia sacra tree has shaped Omani life, its resin — frankincense — once prized as highly as gold. Harvested in the Dhofar region, the milky sap has scented temples and palaces from Rome to China. Even today, the annual spring harvest follows ancient techniques passed down through generations.
Yet this tradition now faces serious threats. Climate change brings longer droughts and unseasonal storms that weaken the trees. Meanwhile, overharvesting to meet global demand leaves bark deeply scarred. Local ecologists report that young saplings struggle to survive, as goats and camels graze on the few that sprout, cutting the natural regeneration rate by nearly half in some valleys.
