Let the forest come back and it does the work: 59% more carbon captured in a Chinese river valley

Between 2000 and 2020, stretches of farmland in the Yiluo River basin — a Yellow River tributary in central China — were turned back into forest and grassland. Researchers tracking the change year by year found the newly forested land now pulls 59% more carbon from the air each year than it did as farmland (29% more where grass returned). The land didn't just look greener from above — its plants were working harder, soaking up more carbon dioxide with every season. It's a hopeful, measurable equation: hand the land back to nature, and nature multiplies the gift.
