A three-year government expedition survey shows soil erosion of 3,569,200 square kilometers. This includes water erosion of 1,612,200 square kilometers and wind erosion of 1,957,000 square kilometers. The ramifications of soil erosion on China’s economic and social development are “far-reaching and even irreversible.” The three-year survey was the largest since 1949 with over 800 participants traveling 140,000 kilometers (315 counties) and analyzing nearly 200,000 questionnaires.
