The Loess Plateau region in China has experienced severe soil erosion for centuries due to deforestation and overgrazing. In 1995, the Chinese government launched the "Grain for Green" program to convert cropland back to forest and grassland, planting trees on over 36,000 square kilometers of eroded hillsides. This ambitious reforestation and revegetation effort helped restore the region's ecosystems while improving the livelihoods of local farmers.
