What has our country implemented in a planned and step-by-step manner to prevent soil erosion?

In order to prevent water and soil erosion, our country has implemented a planned return of farmland to forest and grassland, and implemented ecological resettlement in some areas with serious water and soil erosion.

Soil and water loss is very serious in areas such as the Loess Plateau, Yunnan-Guizhou Plateau, and southeastern hills in my country. Soil erosion in these areas is related to natural factors, but more often due to long-term unreasonable human activities, deforestation, grass destruction, mining, engineering construction, etc. Creating vegetation is an important way to control water and soil erosion, and adjusting the agricultural structure to return farmland to forest and return farmland to grassland is also an important measure.
