China completes historic 1,800-mile “Great Green Wall”
China’s Great Green Wall has helped lift forest cover from under 10% in 1949 to nearly a quarter of the country’s land today, across roughly 1,800 miles of arid north. In dunes near Hongshui village, 78-year-old farmer Wang Tianchang and his family have spent four decades planting sweetvetch shrubs in tidy squares — a technique locals call “holding down the sand” — alongside pines and blue spruces that now shield their fields. Tens of thousands of volunteers join each planting season, and species choices have grown sharper after decades of trial and error. The honest picture includes monoculture missteps and stubborn sandstorms, but Africa’s own Great Green Wall is drawing explicit inspiration — proof that patient, place-based restoration can ripple far beyond where the first seedlings go in.
